Google Ads Audit Checklist 2026: 20 Checks to Stop Wasting Ad Spend

By User Flows Team · April 2026 · 13 min read

Most Google Ads accounts waste 20-30% of their budget on clicks that will never convert. Bad search terms, broken tracking, misaligned landing pages, campaigns fighting each other for the same keywords. The waste compounds quietly, month after month, while your dashboard shows just enough conversions to look acceptable.

This checklist covers 20 specific things to check in your Google Ads account. Every check can be done in your own account without paid tools. If you manage your ads yourself, this will find the leaks. If you have an agency, this will tell you whether they're doing their job. Paid search is one of the five channels in our complete marketing audit framework -- start there if you want to audit everything at once.

Conversion Tracking (Checks 1-4)

If your conversion tracking is wrong, everything else in the account is wrong too. Google's automated bidding strategies optimize toward whatever you tell them is a conversion. Feed them bad data, get bad results.

1. Are your conversion actions correct?

Go to Goals > Conversions > Summary. Review every conversion action listed. Each one should represent a real business outcome: a purchase, a qualified lead form submission, a phone call that lasted more than 60 seconds. If you're counting page views, newsletter signups, or "add to cart" as primary conversions, your bidding algorithms are optimizing for the wrong thing. Move soft conversions to "secondary" so they're tracked but not used for bidding.

2. Is Google Analytics 4 properly linked?

Go to Tools > Data manager > Google Analytics (GA4) links. If GA4 isn't connected, you're missing audience data, cross-channel attribution, and the ability to create remarketing lists from site behavior. Check that the GA4 property matches your live site. If you have multiple properties (common after migrations), make sure the right one is linked.

3. Are conversions actually firing?

In the conversion actions list, check the "Status" column. It should say "Recording conversions." If it says "No recent conversions" or "Inactive," your tracking is broken. Use Google Tag Assistant (tagassistant.google.com) to verify tags are firing on your conversion pages. A surprisingly common problem: tracking was set up once, a site redesign broke it, and nobody noticed for months.

4. Is your attribution model appropriate?

Check your conversion action settings. If you're still using "Last click" attribution, you're ignoring every touchpoint before the final click. Google now defaults to data-driven attribution for most accounts, which is the right choice for most advertisers. If you have low conversion volume (under 300 per month), data-driven may not have enough data to work well -- in that case, "Time decay" or "Position-based" are better alternatives than last click.

Account Structure (Checks 5-8)

5. Are brand and non-brand campaigns separated?

This is the single most important structural decision in any search account. Brand campaigns (people searching your company name) convert at 5-10x the rate of non-brand campaigns. If they're mixed together, your performance data is meaningless. You can't tell what's working because branded traffic inflates everything. Separate them. Always. No exceptions.

6. Does your campaign structure match your business goals?

Open each campaign and check what it's targeting. Campaigns should be organized around business objectives, not arbitrary groupings. Common structures that work: by product category, by funnel stage (prospecting vs. remarketing), by geography, or by margin tier. Common structures that don't: one campaign with everything in it, or 50 campaigns each with $5/day budgets that can never exit the learning phase.

7. Are ad groups tightly themed?

Click into your largest campaigns and check the ad groups. Each ad group should contain 5-20 keywords that share a clear theme. If an ad group has 100+ keywords covering different topics, the ads can't be relevant to all of them. Look at the keyword list and ask: would the same ad make sense for every keyword here? If not, split the ad group.

8. Are your bidding strategies aligned with goals?

Check each campaign's bidding strategy. Manual CPC in 2026 is almost never the right choice -- Google's algorithms have gotten too good at real-time bid optimization. But "Maximize Clicks" is also wrong for most accounts because it optimizes for volume, not value. For most businesses: use "Maximize Conversions" or "Target CPA" if you're optimizing for leads, "Maximize Conversion Value" or "Target ROAS" if you're optimizing for revenue. Make sure each campaign has enough conversion volume (at least 30 per month) to support automated bidding.

Keywords and Search Terms (Checks 9-13)

9. What are you actually paying for?

Go to Insights > Search terms. This shows the actual queries people typed before clicking your ad. Sort by cost, descending. In most accounts, this is where you'll find the biggest waste: irrelevant searches, competitor names you didn't mean to bid on, informational queries from people who will never buy. The search terms report typically reveals 15-30% wasted spend in accounts that haven't been reviewed recently.

10. Is your negative keyword list maintained?

Go to Keywords > Negative keywords. If the list is empty or hasn't been updated in months, you're bleeding money. At minimum, you should have negatives for: competitor names (unless you're intentionally bidding on them), job-related queries ("salary," "careers," "hiring"), informational intent ("free," "what is," "how to"), and anything clearly irrelevant to your business. Build a shared negative keyword list at the account level and apply it to all campaigns.

11. Are your match types intentional?

Check the match type distribution across your keywords. In 2026, broad match paired with smart bidding is Google's recommended approach, and it works well for accounts with strong conversion data. But if your conversion tracking is shaky (see checks 1-4), broad match will spend aggressively on marginal queries. Phrase match gives you more control. Exact match gives you the most control but limits reach. The right answer depends on your conversion volume and how much you trust your tracking.

12. Do you have keyword conflicts?

Search for the same keyword across campaigns. If "blue running shoes" exists in both your Brand campaign and your Non-Brand campaign, they're competing against each other in the auction, inflating your costs. Use Google's built-in "Where your ads showed" report or simply search your keyword list for duplicates. Each keyword should exist in exactly one campaign.

13. Are you bidding on the right keywords?

Pull your keyword list and sort by cost per conversion, descending. Look at the top 20 most expensive keywords. Are they driving conversions at an acceptable cost? Many accounts keep spending on high-volume, expensive keywords out of habit even when the data shows they don't convert. Don't be afraid to pause keywords that have spent 3-5x your target CPA without converting. You can always test them again later.

Ads and Extensions (Checks 14-16)

14. Are you running Responsive Search Ads with strong inputs?

Expanded Text Ads are gone. Responsive Search Ads (RSAs) are now the only standard search ad format. But RSAs are only as good as the headlines and descriptions you give them. Check your ads for: at least 10 unique headlines (not slight variations of the same message), at least 3 descriptions, keyword inclusion in at least 2-3 headlines, a clear call to action, and differentiated value propositions. Check your ad strength indicator. "Poor" or "Average" means Google doesn't have enough variety to test effectively.

15. Are ad extensions (assets) fully built out?

Go to Ads > Assets. At minimum, every campaign should have: sitelinks (at least 4, pointing to relevant pages), callout extensions (highlight key benefits: "Free Shipping," "24/7 Support"), structured snippets (product categories, service types), and a call extension if you accept phone leads. Extensions don't cost extra when they show, but they increase your ad's real estate on the search results page and typically improve click-through rate by 10-15%.

16. Do your ads match your landing pages?

Click through the top 10 ads in your account and land on the destination page. Does the headline on the landing page match the promise in the ad? Does the landing page focus on the same product or service the keyword targets? Sending "running shoes" traffic to your homepage instead of your running shoes category page is one of the most common and costly mistakes. Every ad group should link to a specific, relevant landing page.

Performance Max and Smart Campaigns (Checks 17-18)

17. Is Performance Max cannibalizing your search campaigns?

Performance Max (PMax) campaigns take priority over standard search campaigns for the same queries. If you're running PMax alongside standard search campaigns, check the "Insights" tab on your PMax campaign. Look at the search categories it's capturing. If PMax is eating your branded search traffic (which converts cheaply on its own), it's taking credit for conversions that would have happened anyway. Consider adding brand terms as negative keywords to your PMax campaign or using brand exclusion lists.

18. Do your Performance Max asset groups have strong signals?

PMax campaigns rely on audience signals to guide Google's targeting. Open your PMax campaigns and check each asset group. Are there audience signals defined? These should include your customer lists, website visitors, and in-market audiences relevant to your product. Without signals, PMax will spray your budget across Google's entire network hoping to find conversions. With strong signals, it starts from a much better position.

Budget and Efficiency (Checks 19-20)

19. Are your campaigns limited by budget?

Check the Status column for each campaign. If you see "Limited by budget," that campaign is running out of money before the day ends, meaning Google is throttling your ads during some hours. This isn't always bad -- you might not want to spend more. But if a campaign is profitable and limited by budget, you're leaving money on the table. The fix: either increase the budget, or lower bids to spread the same budget across more of the day.

20. What's your actual return on ad spend?

This is the check that ties everything together. Pull your total Google Ads spend for the last 90 days. Pull your total revenue attributed to Google Ads for the same period. Divide revenue by spend. That's your ROAS. For e-commerce, a healthy ROAS is typically 3:1 to 5:1 depending on your margins. For lead gen, calculate your cost per lead and compare it to your customer lifetime value. If you can't answer this question with confidence, that's the most important finding of your entire audit.

How to Score Your Google Ads Health

Count how many of the 20 checks you passed:

Checks Passed	Account Health	What to Do
18-20	Strong	Focus on scaling winners and testing new audiences
13-17	Good foundation	Fix tracking and structure issues first, then optimize
8-12	Needs work	Prioritize conversion tracking, then negatives and structure
Under 8	Major gaps	Pause spending until tracking and structure are fixed

The Audit Priority Order

If multiple things are broken, fix them in this order:

1. Conversion tracking -- nothing else matters if this is wrong
2. Search term waste -- the fastest way to reclaim budget
3. Brand vs. non-brand separation -- makes all your data meaningful
4. Landing page alignment -- improves conversion rate without spending more
5. Ad copy and extensions -- improves click-through rate and quality score
6. Bidding strategy -- only optimize this after the foundation is solid

The first two items alone -- fixing tracking and cutting search term waste -- typically improve account performance by 15-25% without spending an additional dollar.

Should You Hire a PPC Agency?

You can handle most items on this checklist yourself with a few hours of focused work. Where agencies earn their fee is in ongoing management: weekly search term reviews, bid adjustments, ad testing, and scaling campaigns once the foundation is solid.

Hire an agency when:

• You're spending more than $10,000/month and don't have time for weekly optimization
• You need help with complex setups: Google Shopping, international targeting, or multi-location campaigns
• You've done the basics on this checklist and want someone to push performance further

Don't hire an agency when:

• Your conversion tracking isn't set up (fix that first, then evaluate whether you need help)
• They can't explain their strategy beyond "we'll optimize your campaigns"
• They won't give you full access to your own Google Ads account

Running through this checklist first means you'll know what questions to ask, what a good proposal looks like, and whether the agency is finding real problems or manufacturing them.
