If you’re paying for Google Ads, some searches that trigger your ads will be a poor fit. A person looking for a free template, a job, or a do-it-yourself tutorial may have little chance of becoming a customer—even if the search includes a word from your service or product category. Negative keywords help prevent ads from showing for searches that are unlikely to support Visit the website your business goals.
But adding a long list of exclusions does not automatically mean your agency is managing negative keywords well. The right approach depends on what you sell, who you serve, how people search, and what counts as a valuable outcome for your business. To assess your agency, look beyond the size of its keyword list. Ask whether its decisions are grounded in your commercial goals, backed by reliable measurement, and reviewed with enough context to protect good opportunities.
Start with the business goal, not the traffic report
Negative keywords are a way to shape who sees your ads. They are not a business goal by themselves. Your agency should be able to explain how its exclusions support outcomes such as qualified enquiries, completed purchases, booked consultations, or sales from the right kinds of customers.
Traffic can be useful, but “more traffic” is not a strategy unless you know what kind of traffic matters. An increase in clicks may look positive in a report while producing few useful leads. On the other hand, a lower volume of visits could still be a good result if more of those visitors are a fit for your business.
When reviewing your account, ask your agency to connect each proposed negative keyword decision to a commercial reason. Is the search clearly about a service you do not provide? Is it coming from someone seeking support you cannot offer? Is it a research query that is consistently unlikely to produce a valuable outcome? Those are more useful explanations than “we added negatives to reduce clicks.”
What proper negative keyword management looks like
Regular reviews of the search terms report
The search terms report shows searches that triggered your ads, subject to Google Ads reporting limits and settings. It is one of the main places an agency can find irrelevant queries blocking opportunities—or spending your budget without a reasonable path to a business result.
A capable agency should review this report as an ongoing part of account management, not just during setup. It should identify patterns, investigate unfamiliar terms, and explain what it plans to exclude and why. A one-off cleanup can be a helpful start, but customer language and search behavior change, so exclusions need continuing attention.
Ask to see examples of actual decisions. Your agency should be able to point to a search, describe why it was considered unsuitable, and explain how the exclusion will work. If it only sends a screenshot or a count of added keywords, ask for the reasoning behind the changes.
Careful exclusions—not blanket blocking
Negative keywords can prevent ads from appearing for certain searches, but their matching behavior is not simply the opposite of regular keywords. The effect depends on the negative keyword type and how the person’s search is phrased. That makes context important.
For example, excluding a broad word that appears in both irrelevant and valuable searches can block potential customers along with unwanted traffic. An agency should check where a proposed negative might apply, whether it belongs at the campaign or account level, and whether it could interfere with a relevant product, service, or location.
Be cautious if an agency treats every unfamiliar search as irrelevant or applies the same exclusion list to every campaign without checking what each campaign is meant to do. Search terms need to be judged against your actual offer and targeting—not against a generic list alone.
Lead quality matters more than lead volume
For lead generation, an enquiry is not automatically a good lead. Someone might submit a form but be outside your service area, need a service you do not provide, or have no realistic intention to buy. If your agency optimizes only around the number of form submissions, it may miss the difference between activity and business value.
Your agency should understand what happens after a lead comes in. Does your team qualify it? Is the person contacted? Does the enquiry become a sales opportunity or a customer? A generic CRM can help connect advertising activity with those later stages. Even if the connection is not fully automated, your team can share useful feedback with the agency so campaign decisions reflect real outcomes.
That feedback can also change how negative keywords are handled. A search that appears broad or research-oriented may still produce strong customers for your business. Another search that sounds commercially relevant may repeatedly attract poor-fit enquiries. The agency should use evidence from your sales process—not just assumptions based on wording.
Ask your agency: “How do you distinguish a lead from a qualified lead?” Then ask how that distinction affects campaign management. If the answer is only a higher or lower lead count, you may be looking at a report with metrics but no decisions attached.
Onboarding should include business context
An agency cannot reliably decide which searches are irrelevant if it does not understand the business. A thorough onboarding conversation should cover what you sell, who you serve, which customers are a strong fit, and what types of enquiries your team cannot handle.
It should also cover business details that affect search intent, including:
- Products or services you do—and do not—offer Locations you serve and any areas you exclude Customer types, industries, or project sizes that are a good fit Seasonal changes or capacity limits that affect demand Common reasons you disqualify leads What happens after a form submission, call, or purchase
This context helps the agency avoid both kinds of mistakes: paying for searches that are clearly unsuitable and blocking searches that could lead to valuable business. If your agency started managing ads without asking about these details, that is a reasonable topic to revisit. Better context can make the next round of search term decisions more useful.
Measurement and tracking should come before spend decisions
Before an agency makes confident claims about wasted spend reduction, it needs a clear way to measure what counts as success. If conversion tracking is incomplete, duplicated, or recording the wrong actions, the agency may be evaluating searches using misleading data.
For example, a thank-you page view might be counted as a lead even when a form was not successfully submitted. A phone click might be recorded without confirming whether a meaningful call took place. In ecommerce, tracking may capture a purchase but fail to pass back reliable order value. These are not problems negative keywords can solve.
Ask your agency to explain which actions are tracked, how those actions are tested, and which ones are used to make campaign decisions. Make sure the business agrees on what a conversion means. For lead generation, that may require comparing Google Ads data with qualified enquiries in your CRM. For online sales, it may require checking that reported purchases match the store’s order records.
Measurement does not need to be complicated to be useful, but it does need to be trustworthy. Until tracking is sound, an agency should be careful about saying that a particular search term caused success or waste. It can still make sensible exclusions for obviously unrelated searches, but it should separate informed judgment from conclusions the data cannot support.
Questions to ask your agency
You do not need to be a Google Ads specialist to have a productive review. Ask direct questions and look for clear answers in normal language:
- How often do you review the search terms report? Can you show recent examples of searches you excluded and explain why? How do you check that an exclusion will not block relevant searches? What business information did you use to decide which searches were a poor fit? How do you use lead quality or sales feedback, not just lead volume? Which conversions are being tracked, and have they been tested? What would you do differently next week based on what we learned?
The last question is especially useful. A good review should lead to a practical next step: investigate a query pattern, test a carefully scoped exclusion, fix a tracking issue, or get better feedback from sales. If the agency cannot name an action—or cannot say what evidence would change its mind—the review may be more about presenting activity than improving decisions.
How to review an agency’s work without relying on a giant list
A negative keyword list can look impressive while hiding poor judgment. Instead of judging an agency by how many items it has added, assess the quality of its process. A useful review should connect the business context, the search term, the measurement available, and the next action.
What to review Signs of a sound approach Questions to ask Search term decisions Examples are reviewed in context, with a clear reason for each exclusion. What makes this search unsuitable for our business? Lead quality Campaign feedback includes whether enquiries fit and progress toward a sale. Which leads were useful, and how did that affect your next decision? Tracking Conversions are defined, tested, and checked against business records where possible. What exactly is counted as a conversion? Changes made Changes are documented so the team can understand what happened afterward. What changed, why, and what result would make us keep or reverse it?Documentation matters because changing several things at once makes it hard to know what caused a result. If an agency adds a large batch of negatives, changes targeting, rewrites ads, and adjusts conversion settings in the same period, it may be difficult to tell which change helped or hurt. Ask for changes to be recorded and, where practical, introduced in a way that lets you learn from the outcome.
Common warning signs—and what they may mean
- “We added lots of negatives” without examples: The agency may be reporting activity instead of explaining its decisions. Every low-converting search is excluded immediately: There may not be enough reliable data to judge the search, especially if tracking or lead feedback is incomplete. Only clicks and form fills are discussed: The agency may not be getting enough information about lead quality or sales outcomes. The same list is copied across every campaign: Different offers and audiences may require different decisions. Tracking questions are put off: The agency may be making performance claims before the measurement is dependable.
These signs do not prove that an agency is doing a bad job. They are prompts to ask for context and a clearer plan. For instance, a shared exclusion list can be appropriate for terms that are universally irrelevant to your business—but the agency should be able to explain why that is true in your case.
What a useful reporting rhythm looks like
Good reporting is not a stack of tables and screenshots. It should tell you what happened, what the agency learned, what it changed, and what it recommends doing next. Negative keyword management should fit into that story rather than appear as an isolated count.
Agencies such as ClickSlice (clickslice.co.uk) or other providers should be able to discuss their review process in terms you can follow. If you work with a design partner such as Zeka Design (Zeka Graphic), make sure marketing and website teams share relevant business context too. A campaign can attract the right person, https://instaquoteapp.com/how-do-negative-keywords-fit-into-an-agency-plan/ but unclear service information or a confusing landing page may still affect whether that person becomes a customer.
Ask for a reporting rhythm that gives your team enough time to provide feedback and the agency enough time to evaluate changes. The right schedule depends on your business and how much meaningful data is available. The important part is that reviews produce decisions, and that those decisions are documented rather than lost in a meeting recap.
Making a fair assessment
You can know your agency is using negative keywords properly when it can explain its decisions, connect them to your commercial goals, and show how it protects valuable search opportunities while filtering out poor-fit searches. It should review the search terms report regularly, use business context gathered during onboarding, and treat lead quality as more important than a raw count of leads.
It should also be honest about what the measurement can and cannot prove. Reliable conversion tracking and feedback from your CRM or sales team make it easier to judge which searches are valuable. Without that foundation, an agency may still catch obvious mismatches, but it should not present guesses as precise conclusions.
In your next review, ask for a few examples rather than a bigger list. Find out why each search was included or excluded, what evidence informed the call, and what the agency would do differently next week. That conversation will tell you far more about the quality of its work—and whether its negative keyword strategy is actually helping your business.
