How to Choose a Google Ads Agency 2026

Thousands of businesses across the UK and US hand over their Google Ads accounts to agencies every year. Some do it because they have tried running campaigns themselves and burned through budget without getting results. Others do it because they recognise that managing paid search properly takes more hours than they can spare. Either way, the decision of which agency to hire is just as important as the decision to advertise in the first place.

Get it wrong and you lose three to six months of ad spend, plus the customers you could have acquired during that time. Get it right and the same budget can deliver two or three times more conversions. The problem is that every agency pitches itself as the best. Websites are polished. Case studies are cherry-picked. Testimonials are curated. So how do you cut through the noise and find an agency that will actually perform?

This guide covers everything you need to evaluate before signing a contract: certifications and what they actually prove, the seven criteria that separate good agencies from bad ones, pricing models across the UK and US, red flags that should make you walk away, the questions to ask in your first meeting, and how to measure whether your agency is delivering once you start working together.

Why Use a Google Ads Agency in the First Place?

Google Ads looks straightforward on the surface. Pick some keywords, write a few ads, set a daily budget, click publish. But the gap between launching a campaign and actually generating profitable conversions from it is enormous. Most business owners who try it themselves hit the same wall: clicks come in, money goes out, and the phone does not ring any more than it did before.

The root cause is usually technical. Match types are set too broadly, so half the budget goes to irrelevant search terms. Negative keyword lists do not exist. Ad groups contain too many unrelated keywords crammed together, which drags down Quality Scores. Conversion tracking is either missing entirely or configured incorrectly, which means nobody can tell which keywords are actually driving sales.

And the platform keeps changing. The Google Ads of 2026 barely resembles the version from 2020. Performance Max campaigns, AI-driven bidding strategies, Broad Match combined with Smart Bidding, Demand Gen campaigns across YouTube and Discover.. Google rolls out major updates every quarter. Keeping up with those changes and adapting your campaigns accordingly is a job in itself. A business owner or marketing director who also has to run the rest of the business rarely has the bandwidth to do this properly.

There are specific thresholds where hiring an agency starts to make financial sense:

• When your monthly ad spend passes £2,000 (or $3,000 in the US), the efficiency gains from professional optimisation typically outweigh the agency fee.
• When you need to run multiple campaign types at once (Search, Shopping, Display, YouTube), the workload exceeds what one person can manage well.
• When conversion tracking setup requires Google Tag Manager configuration, GA4 integration, and server-side tracking, you need someone with technical expertise.
• When campaign performance has stalled and you cannot identify why.

If your budget is under £1,000 a month and you only need one simple search campaign, it might be more cost-effective to learn the basics and manage it yourself. But as spend increases and campaign structures become more complex, the return from professional management tends to outstrip the cost of hiring an agency.

Google Partner Badges and Certifications: What Do They Actually Prove?

When you start researching agencies, the first thing you will notice is badges. Every agency website seems to display some combination of Google Partner logos, certification stamps, and award icons. Understanding what these actually mean will help you use them as a filter rather than a deciding factor.

Google Partner vs Premier Partner

Google runs its own partner programme with two tiers. To earn the standard Google Partner badge, an agency needs to meet three requirements: account performance standards (an optimisation score above 70%), a minimum level of ad spend managed across client accounts in the past 90 days, and at least one team member who has passed the Google Ads certification exams.

Premier Partner is a step above. Google awards this status to the top 3% of participating agencies in each country each year. Premier Partners have demonstrated strong client account performance, not just exam knowledge. They also get early access to beta features and dedicated Google support, which can be a genuine advantage.

The real value of these certifications is limited, though. Passing the Google Ads certification exam proves that someone understands the platform’s mechanics. It does not prove they can run profitable campaigns. A surgeon who passed their anatomy exam is not necessarily a good surgeon. Certification sets a floor. An agency without any certified staff is a risk for high-budget campaigns. But a badge alone does not tell you whether they will deliver results for your specific business.

Other Certifications Worth Looking For

Beyond Google’s own programme, a few other certifications signal genuine capability. GA4 certification shows the agency can handle data analysis properly. Google Tag Manager certification indicates technical setup competency. Microsoft Advertising certification means they can run Bing campaigns as well, which matters because Bing still captures 5-8% of search market share in the UK and higher in certain US demographics (particularly among older, higher-income users).

Certifications from Semrush, HubSpot, or similar platforms are less critical but show breadth of marketing knowledge. They are a nice-to-have rather than a must-have.

Seven Criteria for Choosing a Google Ads Agency

1. Account Ownership and Transparency

This is the single most important criterion. If you get nothing else from this article, remember this: you must own your Google Ads account.

The correct setup works like this. The Google Ads account is opened under your business name and linked to your payment method (credit card or bank account). The agency accesses your account through their MCC . They manage campaigns, run optimisations, and build reports from within the MCC. When the relationship ends, you revoke their MCC access. Your account, all its data, campaign history, audience lists, and conversion data stay with you.

The wrong setup: the agency runs your campaigns inside their own account. Ad spend goes through their billing. They invoice you for spend plus fees as a single line item. When you part ways, the account stays with them. Your campaign history, remarketing audiences, keyword performance data, and Quality Score history are gone. You start from scratch.

Transparency goes beyond account ownership. A good agency gives you direct login access to the Google Ads dashboard. You should be able to see which keywords your money is going to, which ads are running, and what the performance looks like, at any time. Be cautious of any agency that says “we will send you reports, you do not need to access the panel directly.” That is a control mechanism, not a service feature.

2. Industry Experience and References

Every industry has different Google Ads dynamics. Healthcare advertising is heavily regulated by Google’s policies and requires careful ad copy. E-commerce depends on product feed optimisation and Shopping campaigns. B2B (business-to-business) has longer sales cycles and different conversion definitions. Local services rely on location targeting and Google Maps placements.

An agency with experience in your sector knows the right keywords from day one. They can estimate average CPC (cost per click) before spending a penny. They understand which ad formats convert best for businesses like yours. An agency without sector experience will spend the first two to three months testing and learning. During that time your ad budget is essentially funding their education.

When you ask for references, do not accept vague statements. “Our clients are happy” tells you nothing. What you want to know: which industry did they work in, what were the starting metrics and ending metrics (ROAS, CPA, conversion volume), how long was the engagement, and what was the monthly budget range. If possible, ask to speak directly with a current or former client.

Agencies that publish concrete case studies with real numbers, the way Bravery shares its success stories, demonstrate a willingness to be held accountable for their work. That transparency is a strong trust signal.

3. Reporting Frequency and Depth

One of the most frustrating aspects of working with an agency is information asymmetry. Your money is being spent and you have no idea what is happening. A solid reporting structure eliminates this.

At minimum you should expect a brief weekly update (spend, clicks, conversions) and a detailed monthly report. The monthly report should include: campaign-level spend breakdowns, keyword performance data, CTR (click-through rate), conversion rates and costs, search terms analysis, month-over-month comparisons, and a plan of action for the following month.

But numbers alone are not enough. A spreadsheet full of metrics without interpretation is not a report. The valuable part is the analysis: what do the numbers mean, why did something go up or down, and what is going to be done about it. Screenshots pasted into a PDF do not count as reporting.

4. Communication and Response Times

When something goes wrong with your campaigns, you need to reach your agency quickly. A disapproved ad, a sudden spike in invalid clicks, a broken conversion tag, these situations require fast action. If your agency takes three days to respond to emails, the best strategy in the world cannot save you.

Clarify the communication structure before signing. Will you have a dedicated account manager? What channels do they use (email, Slack, Microsoft Teams, phone)? What is the expected response time for urgent issues? Will there be regular monthly or bi-weekly calls?

A common pattern across the industry: agencies are extremely responsive during the sales process and go quiet after the contract is signed. The way to prevent this is to include minimum communication standards in the contract. Weekly updates and monthly review calls should be written into the agreement, not left as verbal promises.

5. Campaign Management Approach

Ask the agency how they will actually manage your campaigns. “We set up and optimise” is a generic answer that tells you nothing. The specifics matter:

• How do they structure campaigns and ad groups? Single keyword ad groups, themed groups, or something else?
• What bidding strategy do they prefer and why? Do they default to automated bidding or start with manual?
• Do they run A/B tests on ad copy? How frequently?
• How often do they review the search terms report?
• What is their process for negative keyword management?
• Do they provide landing page recommendations, or is that outside their scope?

An agency that gives clear, detailed answers to these questions knows what it is doing. If you hear “we tailor our strategy to each client” without any concrete details about what that strategy looks like for your business, consider it a soft red flag. They should be able to describe a specific approach based on your industry and budget, even in the first conversation.

6. Technical Capability

A competent Google Ads agency does more than write ads and pick keywords. It ensures the technical infrastructure behind your campaigns is working correctly. Conversion tracking is the most critical piece of this puzzle.

Running Google Ads without proper conversion tracking is flying blind. You cannot optimise campaigns if you do not know which keywords lead to sales, which ads generate form submissions, and which landing pages convert. Your agency should be proficient in Google Tag Manager setup, GA4 integration, server-side tracking, and offline conversion imports.

In 2026, privacy regulations and cookie restrictions have made tracking harder. Data loss from iOS users is significant. Third-party cookies are being phased out. Agencies that can correctly implement Enhanced Conversions, Consent Mode v2, and first-party data strategies have a real competitive edge. Ask about their approach to these challenges. If they look confused, that is a problem.

You can see how we handle these technical details on our Google Ads services page.

7. Contract Terms

Contract details define the health of your relationship with the agency. Pay close attention to three areas.

Minimum term. A three-month minimum is reasonable. In Google Ads, the first month is setup and data collection, the second month is initial optimisation, and meaningful performance assessment is only possible from the third month onward. A one-month contract does not give the agency enough time. A twelve-month lock-in contract gives you no exit if things go badly. Three to six months with a rolling notice period after that is a fair middle ground.

Termination clauses. How much notice is required to end the contract? Is there an early exit penalty? When you leave, are the Google Ads account and all data transferred to you in full?

Competitor exclusivity. Will the agency work with your direct competitors at the same time? Some agencies take on multiple clients in the same industry and the same geographic market, which creates a conflict of interest. Ask whether they offer a competitor exclusion clause. It is not always available, but it is worth discussing.

Pricing Models: What UK and US Agencies Charge

Pricing is where most confusion lives in the agency selection process. Different agencies use different models, and each has trade-offs. Understanding the landscape will help you evaluate whether a proposal is fair.

UK Agency Pricing in 2026

Monthly management retainers from professional UK agencies range from £1,000 to £5,000 per month. Where you land in that range depends on the number of campaigns being managed, the complexity of your account structure, the depth of reporting, and the agency’s level of experience.

At the lower end (£1,000-£1,500), you are typically getting a single-platform setup with basic optimisation and monthly reporting. At the upper end (£3,000-£5,000), expect multi-campaign management, weekly optimisation cycles, detailed analytics reporting, landing page recommendations, and a dedicated senior account manager.

Be cautious with quotes below £750 per month. At that price point, the time an agency can realistically allocate to your account is minimal. Your campaigns will likely run on autopilot with little active management. You will pay less, but you will also get less.

For the percentage-of-spend model, 10-15% is standard in the UK market. On a £10,000 monthly spend at 12%, that works out to £1,200 per month in management fees. As spend increases, the percentage should decrease. Paying 15% on a £50,000 monthly spend (£7,500 in fees) may not be proportionate to the work involved.

US Agency Pricing in 2026

US agencies tend to charge more than their UK counterparts. Monthly retainers range from $1,500 to $8,000, with the average for a mid-market agency sitting around $2,500 to $4,000. Top-tier agencies in competitive markets like New York, Los Angeles, or San Francisco can charge $10,000 or more per month, though at that level you should be getting a senior strategist and a full support team.

The percentage-of-spend model is also common in the US, typically at 10-20%. Some agencies set a minimum management fee alongside the percentage. For example, “15% of spend or $2,000, whichever is greater” ensures the agency gets adequate compensation even on lower-spend months.

One pricing detail to watch for on both sides of the Atlantic: some agencies route your ad spend through their own billing accounts and invoice you for everything as a single amount. In that model, you have no visibility into how much is going to Google and how much is going to the agency. Your budget should flow directly to Google. The agency fee should be a separate, clearly itemised charge. Anything else is a transparency issue.

Red Flags That Should Make You Walk Away

Certain warning signs indicate that an agency is not worth your time or money. If you spot any of the following during the evaluation process, look elsewhere.

“Guaranteed” results. “We guarantee page one” or “10x ROAS within three months, guaranteed.” Google Ads runs on an auction system. Competitor bids, industry dynamics, seasonality, and Google’s own algorithm changes all affect outcomes. No agency controls these variables. The most honest thing an agency can say is: “Based on our experience in similar industries, we expect results in the range of X to Y.” Guarantees are a sales tactic, not a service commitment.

Refusing to share account access. If the agency will not give you direct access to your Google Ads dashboard, they are either hiding something or planning to hold your data hostage when you leave. Neither is acceptable. Walk away immediately.

Long mandatory contracts. A 12 or 24-month lock-in contract can signal that the agency does not trust its own ability to retain clients through performance. An agency that is confident in its work will offer a three-month initial term followed by a rolling monthly arrangement. If the results are good, you will stay. They should not need a contract to keep you.

The one-person “agency.” There is nothing wrong with hiring a freelancer. In fact, for certain budgets and single-platform needs, a freelancer can be the smart choice. The red flag is when a solo practitioner presents themselves as an agency. If they get sick, go on holiday, or take on too much work, who manages your account? Misrepresenting team size is a transparency problem.

Reporting by meeting only. “We go through everything in our monthly call” is not a substitute for written reports. Verbal updates are forgotten, cannot be referenced later, and do not create the trend data you need to evaluate performance over time. You should receive a written report every month that you can review, compare to previous months, and share with stakeholders.

“We are experts in every platform.” Google Ads, Meta Ads, TikTok Ads, LinkedIn Ads, Pinterest Ads, Amazon Ads, programmatic display.. claiming deep expertise across every platform is unlikely. An agency with strong capability in two to four platforms is more credible than one that claims to do everything equally well. Deep expertise beats surface-level coverage.

Ten Questions to Ask in Your First Meeting

The initial conversation with a prospective agency is your best opportunity to assess their competence and professionalism. These ten questions will surface the information you need to make a decision.

1. Who will own the Google Ads account? The answer should be “you.” If they hesitate or propose running campaigns in their own account, end the conversation.
2. Have you worked in our industry before? What results did you achieve? Ask for specific numbers: starting CPA, ending CPA, ROAS improvement, conversion volume changes. General statements do not count.
3. How many people on your team work on Google Ads? Understand the roles: account manager, strategist, technical specialist. Know who will actually be handling your account day to day.
4. What does your reporting look like? Ask to see a sample report. Weekly updates plus a monthly detailed report should be the minimum.
5. Do you handle conversion tracking setup? The answer should be yes, and they should be confident discussing GA4, Google Tag Manager, Enhanced Conversions, and Consent Mode.
6. How many hours per week will you spend on our account? Get a concrete time commitment. “As much as needed” is not an answer.
7. Walk me through how you would build our campaign strategy. They should describe a process: competitor analysis, keyword research, campaign structure planning, ad copy development, and landing page assessment.
8. What is the typical CPC and conversion cost in our industry? An experienced agency should be able to give you an approximate range, even if they caveat it.
9. What is your minimum contract term and what are the early termination conditions? Get clear, written answers.
10. Can we speak with one of your current or past clients? A confident agency will facilitate this. Reluctance is a warning sign.

The clarity and specificity of the answers you receive will tell you more than any sales deck. If responses are vague, evasive, or heavy on jargon but light on substance, you do not need a second meeting.

Agency Types: Boutique, Large, or Freelancer?

Choosing a Google Ads agency is not just about which specific company to hire. It is about what type of agency fits your needs. Each model has strengths and weaknesses, and the right choice depends on your budget, complexity, and expectations.

Large Agencies (50+ People)

Big teams, departmentalised structures, multi-platform capabilities. The large agencies in the UK and US manage portfolios worth hundreds of thousands per month in ad spend. Their advantages: backup staff when someone is unavailable, capacity to run campaigns across multiple platforms simultaneously, and the ability to offer creative services (landing page design, video production) alongside PPC management.

The downsides are real, though. If your account has a modest budget, you may end up low on the priority list. It is common for large agencies to assign junior staff to smaller accounts while senior strategists focus on the big spenders. Decision-making can be slow because multiple layers of approval are required. And the personal attention you receive tends to diminish as the agency grows its client roster.

Boutique Agencies (5-20 People)

These are typically specialists. They focus on one or two platforms or on specific industries. Bravery sits in this category. The advantages: more personal attention, faster decision-making, direct access to the people doing the work, and flexibility. Boutique agencies often limit their client count deliberately, which means each account gets a meaningful allocation of time and expertise.

The trade-off is resource depth. A boutique agency may not have the capacity for extremely large, multi-market campaigns that require a team of ten people. Platform coverage may be narrower than what a large agency offers. But for most mid-market businesses, the trade-off is worth it.

Freelancers and Independent Consultants

Solo practitioners, usually former agency employees or specialists who have gone independent. Advantages: lower cost, direct communication with the person doing the work, high flexibility, and often a deep understanding of the platform from years of hands-on experience.

Disadvantages: no backup when they are ill, on holiday, or overloaded with work. A single person cannot be equally strong in analytics, creative, and technical implementation. Long-term business continuity is a risk. If they decide to stop freelancing, you need to find a replacement quickly.

As a rough guide: if your monthly spend is under £2,000 and you only need one platform managed, a skilled freelancer can be an excellent choice. For £2,000 to £10,000 in monthly spend with multiple campaign types, a boutique agency is typically the better fit. For £10,000+ monthly spend with multi-platform, multi-market needs, a larger agency may make more sense. But quality always matters more than size. A brilliant boutique agency will outperform a mediocre large one every time.

How to Measure Your Agency’s Performance

You have chosen an agency, signed the contract, and campaigns are live. Now what? Understanding how to evaluate whether your agency is delivering value requires looking at the right metrics at the right times.

Months 1-3: Setup and Baseline

The first month should be focused on account structure, conversion tracking verification, keyword research, and campaign launch. Expect limited data during this period. By months two and three, initial data starts coming in: which keywords are driving conversions, which ads perform better, whether CPC levels are in line with industry norms.

This period establishes your baseline. Do not expect miraculous results in the first 30 days. But by the end of month three, you should see measurable progress and a clear direction. If the agency is still “getting set up” after three months, that is concerning.

Months 3-6: The Optimisation Window

This is where a good agency earns its fee. With enough data accumulated, campaign structure should be refined. Poor-performing keywords should be paused or removed. High performers should get increased budget allocation. Ad copy A/B tests should be running. ROAS (return on ad spend) or CPA (cost per acquisition) trends should be moving in the right direction.

The core metrics to monitor during this period:

• Conversion volume: Is it increasing month over month?
• Cost per conversion (CPA): Is it decreasing, or at least holding steady?
• Quality Score: Are scores above the platform average (aim for 6+)?
• Search term relevance: Is budget still leaking to irrelevant queries, or is it concentrated on high-intent terms?
• Impression share: How much traffic are you missing due to budget or rank constraints?

Month 6 Onwards: The Verdict

Six months gives you a clear picture of agency performance. Campaign data has matured, seasonal fluctuations have been accounted for, and enough optimisation cycles have occurred to show a trend. If CPA has not improved, conversion volume has not grown, and the agency’s reports still say “we are testing, we need more time,” it is time for a serious conversation.

But be fair in your evaluation. Factors outside the agency’s control also affect performance. If competitor activity has increased and driven up CPCs across the board, if your website loads slowly and kills conversion rates, or if your pricing is not competitive, those issues will drag down campaign results regardless of how well the campaigns are managed. Distinguish between agency performance and market conditions.

Switching from One Agency to Another

If you are already working with an agency and performance is not where it should be, switching is an option. But a poorly managed transition can cause a significant dip in campaign results. Planning the move carefully protects your investment.

Before ending things with your current agency, secure the following:

• Confirm that the Google Ads account is owned by you. If it is not, resolve this before anything else.
• Verify that conversion tracking tags are in your own Google Tag Manager container.
• Ensure remarketing lists and audience data are stored in your account.
• Download or save copies of all historical campaign reports.
• Check that any scripts, custom rules, or automated processes are documented.

Work with the new agency to create a transition plan. There should be no gap where campaigns are paused. In the ideal scenario, the new agency reviews the existing campaign structure, prepares their recommendations, and on transition day, MCC access is switched without any interruption to live campaigns.

Some performance fluctuation during the handover period is normal. The new agency needs four to six weeks to analyse the existing setup, plan changes, and implement them gradually. Knowing this in advance helps set realistic expectations. A new agency that promises to completely overhaul everything on day one is likely to cause more disruption than improvement.
