How Do I Compare Two Google Ads Agencies Without Getting Fooled?

Comparing two Google Ads agencies can feel straightforward: look at their proposals, compare the promised results, and choose the one that sounds more confident. That is also how businesses end up buying attractive reports, vague promises, or a lot of clicks that never become customers.

A useful comparison is less about which agency has the slicker deck and more about which one understands your business, can measure the outcomes that matter, and has a credible plan for improving them. This guide gives you a practical way to evaluate two proposals side by side—without pretending you can predict exact results before the work begins.

Whether you are considering agencies such as Zeka Design (Zeka Graphic) or ClickSlice (clickslice.co.uk), apply the same questions to both. The goal is not to assume one is right for you. It is to find out how each would work with your specific goals, data, budget, and constraints.

Start With the Business Goal, Not the Traffic Goal

“We want more traffic” is not a useful brief on its own. Traffic only matters if the right visitors take actions that help the business. Before comparing agencies, define what success means in commercial terms.

For an ecommerce company, that might mean profitable sales, new-customer revenue, or a target return after accounting for product margins. For a local service business, it could mean qualified enquiries, booked appointments, or completed jobs. The right measure depends on how your business earns money—not on which number is easiest to make go up.

Ask each agency to connect its proposed Google Ads work to your business goal. A good answer should explain the steps between advertising and revenue: what action the campaign is intended to generate, how that action will be measured, and how you will judge its value.

• For ecommerce: What counts as a valuable order? Do returns, cancellations, margins, and repeat purchases matter?
• For lead generation: What makes an enquiry qualified? Which services, locations, or customer types are most valuable?
• For a longer sales cycle: How will advertising results be connected to later opportunities or closed deals in your CRM?

Be wary if an agency focuses heavily on impressions, clicks, or click-through rate without explaining how those metrics support a business outcome. Those numbers can help diagnose campaign performance, but they are not automatically proof that the campaign is making money.

Compare Lead Quality, Not Just Lead Volume

More leads are not always better. A campaign can generate a large number of enquiries that are outside your service area, looking for the wrong product, unable to afford your offer, or simply not ready to buy. If the agency reports only the number of form submissions, you may mistake activity for progress.

Ask how each agency will define and assess lead quality. Ideally, the plan includes a way to distinguish a raw enquiry from a qualified opportunity or customer. This might involve connecting Google Ads data with your CRM, using consistent lead-status definitions, or regularly sharing sales outcomes with the agency.

For example, “qualified lead” should mean something specific to your team. It could require a suitable location, a relevant project, a valid contact, and a sales conversation that meets agreed criteria. If your sales team does not currently label leads consistently, that is important context—not a reason to ignore quality.

Questions That Reveal Whether Quality Is Part of the Plan

• How will we identify which campaigns generate qualified leads, not just form fills?
• What information do you need from our sales team or CRM?
• How often will we review lead quality and adjust targeting or messaging?
• What happens if lead volume rises but the share of qualified leads falls?

A strong agency should be comfortable discussing that trade-off. In some cases, reducing low-quality lead volume is a good result if it frees the team to focus on more valuable opportunities. Get agreement on the business outcome before the campaign launches, so a later conversation is not a debate over what the word “lead” was supposed to mean.

Ask for Reporting Examples, Not Just Reporting Promises

“We provide transparent reporting” sounds reassuring, but it does not tell you what you will receive or whether the report will help you make a decision. Ask for a redacted reporting example or a sample dashboard. The format matters less than whether it explains what happened, why it matters, and what the agency recommends doing next.

A useful report should not be only tables and screenshots. It should make the key results easy to understand and show how they connect to your goals. It should also explain changes in measurement, campaign activity, and business conditions that may have affected performance.

What to Look For What a Useful Example Shows What to Question Business outcomes Leads, qualified opportunities, sales, or another agreed result Only impressions, clicks, or platform scores Context What changed, what may have caused it, and what is uncertain A claim that performance improved with no explanation Recommendations Clear next steps tied to evidence and a business goal A list of metrics with no decisions attached Measurement notes Tracking limitations, data gaps, and any changes made Numbers presented as exact despite known tracking issues

Ask each agency to talk you through the sample in plain language. You should be able to answer: What happened? What did we learn? What should we do differently next week? If the report cannot support that conversation, it may be polished but not very useful.

Compare the Testing Approach, Not the Number of Ideas

Every agency can produce a list of things to try. The more important question is how it will choose tests, measure them, and decide what to do with the results. A credible testing approach is focused and controlled. It does not change five things at once and call the outcome a test.

Ask each agency to walk through one example of a proposed test. A clear explanation should cover the business question, the change being made, the measure of success, and how the result will inform the next step. For instance, an agency might test whether a message emphasizing faster service produces more qualified enquiries than a message emphasizing a lower starting price. The measure should reflect the goal—not just which ad receives more clicks.

Testing Approach Comparison

1. Question: What uncertainty are we trying to resolve?
2. Change: What specific part of the campaign will change?
3. Measure: What result will indicate that the change helped?
4. Decision: What will we do if the test wins, loses, or remains inconclusive?

Do not expect every test to produce a dramatic win. Some tests will be inconclusive, particularly when there is limited conversion volume. The important thing is that the agency explains what it learned and avoids overstating what the data can prove.

When comparing proposals, look for a sensible order of work. An agency may need to fix measurement or search coverage before testing new creative. Another may have enough reliable data to prioritize a specific campaign experiment. The plan should fit your account and business context, rather than being a generic list presented to every prospect.

Make Onboarding Prove They Understand Your Business

Onboarding is not a formality before the “real” work starts. It is where the agency learns what your business sells, who it serves, what makes a customer valuable, and what operational limits affect advertising. A proposal that skips those questions may be based on assumptions that will later shape the wrong campaigns.

Ask what the agency needs to learn before recommending changes. Good onboarding often covers your products or services, margins or commercial priorities, geography, seasonality, sales process, capacity, customer objections, competitors, and past advertising history. You do not need to share every detail in an initial meeting, but the agency should show curiosity about the factors that shape results.

Consider whether the agency asks what happens after someone clicks an ad. Do enquiries receive a quick response? Are some services more profitable than others? Can your team handle more demand in a particular location? These details can change which campaigns make sense. A business that cannot serve extra demand should not be pushed toward “more volume” without a plan.

Ask for a clear onboarding sequence: who needs to be involved, what access is required, what decisions you need to make, and what the agency will deliver before campaigns are changed. That gives both sides a chance to spot missing information early.

Check Measurement and Tracking Before Spend

Before increasing ad spend, confirm that the actions you care about are being recorded accurately. If conversion tracking is wrong, the agency may optimize toward duplicate, low-value, or irrelevant actions. More budget will not fix a broken measurement setup; it may simply make the wrong signal louder.

Ask how the agency will audit Google Ads conversion tracking and check that it reflects real business outcomes. Depending on your setup, this may involve reviewing tags, forms, calls, ecommerce events, consent settings, and the way conversions are imported or counted. The agency should explain what it can verify and what it needs your team or technical provider to confirm.

For lead generation, ask whether the team can connect ad activity to downstream statuses in your CRM. For ecommerce, check that the tracked purchase value is meaningful and that important order adjustments are understood. The goal is not to collect every possible data point. It is to have trustworthy measurements that support decisions.

Also clarify account access and ownership. You should know who owns the Google Ads account and tracking assets, who can view them, and how you will retain access if the relationship ends. A professional working arrangement should not leave you unable to inspect your own advertising history or measurement setup.

Do Not Let Missing Numbers Create False Confidence

One common mistake when comparing proposals is treating the absence of pricing, retainers, ad spend figures, or CPA numbers as though it makes two offers comparable. It does not. If those numbers are not provided, you cannot make a like-for-like financial comparison or assess whether the proposed scope fits your budget.

Ask both agencies to clarify the commercial details in writing. Separate the agency fee from the media budget paid to Google, and ask what work the fee includes. Confirm any setup costs, contract length, notice period, extra charges, and the process for approving changes in scope.

Ask about CPA targets only with the necessary context. A cost per acquisition can be useful if the agency knows what counts as an acquisition, whether it is a lead or a sale, and what that outcome is worth to your business. A low CPA is not automatically good if the leads do not convert or the sales are unprofitable. A forecast should be described as an estimate with assumptions, not a guarantee.

If an agency cannot provide a responsible forecast before reviewing your account, that may be reasonable. If it promises exact results without explaining its assumptions, be cautious. You need enough information to plan, but you do not need false precision.

Agency Proposal Red Flags to Watch For

• Guaranteed outcomes: Exact sales, lead, or ranking promises without a clear basis.
• Vanity metrics as the main success measure: More clicks or impressions, with no agreed link to business value.
• Vague testing: A long list of changes without a stated question, measure, or decision rule.
• One-size-fits-all recommendations: The same campaign plan regardless of your products, customers, or sales process.
• Unclear tracking ownership: No explanation of who controls the accounts, data, and measurement setup.
• Missing commercial terms: No clear fee, scope, media budget, or contract details.
• Reporting without action: Regular metrics, but no explanation of what the agency recommends changing.

A single concern does not automatically disqualify an agency. Use it to ask a direct follow-up question. The quality of the answer—clear, specific, and honest about uncertainty—is part of what you are evaluating.

Use a Simple Scorecard to Compare Both Agencies

After the meetings, score each agency against the same criteria. Do not give extra credit for presentation polish if the substance is missing. You can use a simple rating from one to five, then write down the evidence behind each score.

Criteria What You Are Assessing Commercial understanding Do they connect advertising to revenue, margin, qualified opportunities, or another real goal? Lead or customer quality Can they account for what happens after a form fill, call, or purchase? Onboarding Do they ask for the business context needed to make sound recommendations? Measurement Will they verify tracking and explain any limitations before scaling spend? Testing Is there a clear comparison method and a plan for making decisions from results? Communication and cost Are reporting, responsibilities, fees, media spend, and contract terms understandable?

Do not let the final score make the decision for you. Use it to surface differences and questions. If one agency scores well on presentation but poorly on measurement, that is more useful to know than simply saying its proposal “felt stronger.”

Choose the Agency That Makes the Next Decision Clearer

You cannot know in advance which agency will produce the best results. You can, however, judge whether each one has asked the right questions, treated measurement seriously, and explained how it will make decisions once the work begins.

Before signing, ask both agencies to summarize what they believe your main commercial goal is, what they would verify first, and what they would do differently next week if early results showed that lead quality was weak. Their answers should be specific enough to https://dibz.me/blog/how-do-i-set-shared-objectives-with-a-google-ads-agency-1288 show thought, but honest enough to acknowledge what they do not yet know.

The best partner is not necessarily the one promising the most traffic or presenting the boldest forecast. It is the one that can connect Google Ads activity to business outcomes, work with your team and CRM to understand quality, report in a way that supports decisions, and test changes without confusing activity for evidence.
