The 47-Point Google Ads Audit Checklist (2026 Edition)

We audit between 10 and 15 Google Ads accounts every month. Budgets range from $2,000/month local businesses to $200,000/month e-commerce brands. Industries span SaaS, professional services, DTC, lead gen, and everything in between.

And the pattern is always the same: most accounts are wasting 25-40% of their budget on preventable mistakes. Not obscure technical issues — fundamental structural problems that compound over time. A misconfigured conversion action here, a broad match keyword leaking budget there, a missing negative keyword list draining $500/month on irrelevant clicks.

This is the exact checklist our team uses on every audit. 47 points across 12 categories. Print it, bookmark it, run through it quarterly. Every point you fix compounds into better performance.

1. Account Structure

Account structure is the foundation. A poorly structured account makes optimization nearly impossible — campaigns compete against each other, budgets get misallocated, and reporting becomes meaningless.

Check #1: Campaign-to-goal alignment

Every campaign should map to a single business goal. One campaign for branded search. One for non-branded high-intent keywords. One for competitor terms. One for Shopping. Mixing goals in a single campaign dilutes budget allocation and confuses the algorithm's optimization signals.

Check #2: Ad group theme purity

Each ad group should contain tightly themed keywords — ideally 5-15 keywords that share the same intent. If an ad group contains "google ads agency" and "social media marketing," the ad copy can't be relevant to both. Tight themes mean better ad relevance, better Quality Scores, and lower CPCs.

Check #3: Search vs. Performance Max separation

In 2026, most accounts run both Search and Performance Max campaigns. Verify they aren't cannibalizing each other. PMax will poach branded traffic from Search campaigns by default. Use brand exclusions in PMax or run a branded Search campaign at high priority to maintain control over your highest-converting queries.

Check #4: Campaign naming conventions

This sounds trivial. It isn't. Consistent naming conventions (e.g., [Network]_[Goal]_[Audience]_[Geo]) make filtering, reporting, and optimization 10x faster. If campaign names are random or inconsistent, you lose time every single day trying to find what you're looking for.

Check #5: Location targeting settings

One of the most common budget leaks: location targeting is set to "Presence or interest" instead of "Presence: People in or regularly in your targeted locations." The default setting shows ads to people who are merely interested in your location — meaning someone in another country researching your city will see your ads. Switch to "Presence" only.

2. Conversion Tracking

Conversion tracking is the single most important technical foundation in Google Ads. Without accurate tracking, the algorithm optimizes blind, your Smart Bidding underperforms, and your reporting is meaningless. We find tracking errors in roughly 60% of the accounts we audit.

Check #6: Primary vs. secondary conversion actions

Only your primary business objective (purchase, qualified lead, phone call) should be set as a primary conversion action. Everything else — page views, form starts, button clicks — should be secondary. Google's Smart Bidding optimizes toward primary conversions. If you have 8 primary conversion actions, the algorithm doesn't know what you actually want.

Check #7: Conversion value accuracy

For e-commerce: are dynamic conversion values passing the correct order total (excluding tax and shipping)? For lead gen: have you assigned realistic values to each conversion type? A demo request and a newsletter signup shouldn't have the same value. Value-based bidding (tROAS) only works if values are accurate.

Check #8: Enhanced conversions enabled

Enhanced conversions use first-party data (hashed email, phone, address) to improve conversion attribution accuracy by 5-15%. This is no longer optional in 2026. With cookie deprecation and browser privacy restrictions, enhanced conversions recover data that would otherwise be lost.

Check #9: Consent mode v2 compliance

If you serve EU/EEA traffic, Consent Mode v2 is mandatory. Verify that your Google tags fire correctly in both consented and unconsented states. Without proper consent mode, you're either violating privacy regulations or losing all conversion data from users who don't consent.

Check #10: Offline conversion import

For lead gen businesses: are you importing offline conversion data (CRM stage changes, closed deals) back into Google Ads? Click-to-lead is a vanity metric. What matters is click-to-revenue. Importing offline conversions lets Smart Bidding optimize for leads that actually close, not just leads that submit a form.

3. Keyword Strategy

Keywords are where intent meets budget. The wrong keyword strategy means you're paying to attract people who will never convert. The right strategy puts your ads in front of buyers at the exact moment they're ready to act.

Check #11: Match type distribution

Review your mix of exact, phrase, and broad match keywords. In 2026, broad match paired with Smart Bidding has gotten significantly better — but only if your conversion data is strong (50+ conversions/month). If you're under that threshold, phrase and exact match give you more control. Check the search terms report to verify broad match isn't matching to irrelevant queries.

Check #12: Search terms audit

Pull the search terms report for the last 90 days. Sort by cost (descending) and look for terms that are spending money but not converting. We typically find 15-25% of spend going to irrelevant search terms in unaudited accounts. These become your negative keywords.

Check #13: Keyword intent alignment

Not all keywords carry the same buying intent. "Best CRM software" is research. "HubSpot pricing" is consideration. "Buy HubSpot enterprise" is decision. Group keywords by intent stage and ensure your ad copy and landing pages match. Bidding the same amount on research keywords as you do on decision keywords wastes money.

Check #14: Keyword cannibalization

Are multiple campaigns or ad groups bidding on the same keywords? This forces your campaigns to compete against each other in the auction, driving up costs. Use the auction insights and keyword overlap reports to identify cannibalization. Consolidate overlapping keywords into a single ad group.

Check #15: Low search volume keywords

Keywords marked "Low search volume" aren't serving ads. They clutter your account and make management harder. Remove or consolidate them into broader match types. An account with 5,000 keywords where 3,000 are inactive isn't well-optimized — it's neglected.

4. Ad Copy & Creative

Your ad copy is the first impression. It determines whether someone clicks your ad or your competitor's. In 2026, with AI-generated ad suggestions everywhere, the bar for ad quality is higher than ever.

Check #16: Responsive search ad completeness

Each RSA should have 15 headlines and 4 descriptions — the maximum allowed. Google tests combinations to find winners. Fewer assets means fewer combinations, which means slower learning and worse optimization. Check that headlines include your primary keyword, unique value propositions, and clear CTAs.

Check #17: Ad strength score

Google rates every RSA as Poor, Average, Good, or Excellent. While ad strength isn't a direct ranking factor, it correlates with reach. Ads rated "Poor" get significantly less impression share. Aim for "Good" or "Excellent" on every ad. Fix common issues: add more unique headlines, include keywords in headlines, vary your messaging angles.

Check #18: Pin strategy

Are critical messages pinned to position 1? If your brand name or primary offer must always appear, pin it. But don't over-pin. Pinning every headline to a specific position eliminates Google's ability to test combinations. We recommend pinning 1-2 headlines maximum — your brand and your strongest value prop — and letting the rest rotate.

Check #19: Ad variation testing

Every ad group should have at least 2-3 active RSAs for testing. If you've been running the same single ad for 6+ months, you're leaving performance on the table. Set up an ad testing schedule: new variation every 6-8 weeks, pause losers after statistical significance, keep iterating.

5. Landing Pages

The best ad in the world can't fix a bad landing page. We consistently find that landing page improvements deliver 2-5x the impact of ad copy changes.

Check #20: Message match

Does the landing page headline match the ad? If your ad says "50% Off First Month," the landing page should say "50% Off First Month" above the fold. Message mismatch increases bounce rate by 30-50%. Run through your top 10 ads by spend and verify each landing page delivers on the ad's promise.

Check #21: Page speed

Run every landing page through Google PageSpeed Insights. Target 90+ on mobile. Every second of load time above 3 seconds costs you 7% of conversions. Google also factors page speed into Quality Score, so slow pages mean higher CPCs. Common fixes: compress images, defer non-critical JavaScript, use a CDN.

Check #22: Mobile optimization

60-70% of Google Ads clicks happen on mobile. Check every landing page on an actual phone, not just a desktop resize. Verify: forms are easy to fill on mobile, CTAs are thumb-reachable, text is readable without zooming, no horizontal scrolling, click-to-call works.

Check #23: Conversion rate by landing page

Pull conversion rates for every landing page in Google Analytics. Any page below 2% for e-commerce or 5% for lead gen needs attention. Rank pages by volume and conversion rate to prioritize fixes. Often, improving your top-traffic landing page from 3% to 5% has more impact than launching a new campaign.

6. Bidding Strategy

Bidding strategy determines how much you pay for every click. The wrong strategy can quietly double your costs. The right one can cut CPA by 30% without changing anything else.

Check #24: Smart Bidding readiness

Smart Bidding (tCPA, tROAS, Maximize Conversions) needs sufficient data to work. The minimum is 15-30 conversions per month per campaign, but 50+ is where performance stabilizes. If a campaign has fewer than 15 conversions/month, manual CPC or Maximize Clicks may perform better until you hit volume.

Check #25: Target CPA/ROAS accuracy

Is your target CPA set based on actual business economics, or a guess? Calculate your true CPA target: (Average Order Value x Profit Margin) / Target ROI. Setting targets too aggressively restricts delivery. Setting them too loosely wastes budget. Start with your actual historical CPA and adjust by 10-15% increments.

Check #26: Portfolio vs. campaign-level bidding

Portfolio bid strategies share data across multiple campaigns, which helps when individual campaigns have low conversion volume. If you have 5 campaigns each getting 10 conversions/month, a portfolio strategy combining them gives the algorithm 50 data points — crossing the threshold where Smart Bidding excels.

Check #27: Bid adjustments review

Check device, location, and time-of-day bid adjustments. In automated bidding, most adjustments are overridden — but device adjustments still work. If mobile converts at half the rate of desktop, consider a -30% mobile bid adjustment even with Smart Bidding. Also check for legacy bid adjustments from before you switched to automated bidding — they may be hurting performance.

7. Negative Keywords

Negative keywords are the most underrated lever in Google Ads. They prevent waste by stopping your ads from showing on irrelevant searches. We've saved clients $2,000-$15,000/month in wasted spend through negative keyword optimization alone.

Check #28: Shared negative keyword lists

Create account-level shared negative keyword lists for universal exclusions: "free," "jobs," "salary," "how to," "DIY," "reddit," "youtube." Apply these lists to every campaign. Without them, each new campaign starts from zero — leaking money on the same irrelevant terms.

Check #29: Brand term exclusions in PMax

Performance Max campaigns aggressively serve ads on branded searches by default. If you're running a separate branded Search campaign (which you should be), add brand exclusion lists to your PMax campaigns. Without this, PMax takes credit for conversions your branded campaign would have captured anyway, inflating its apparent ROAS.

Check #30: Competitor term exclusions (where appropriate)

If you're not intentionally bidding on competitor terms, add competitor brand names as negatives. Competitor clicks are typically expensive (high CPC) and low-converting (the user wanted your competitor, not you). Unless you have a specific conquest strategy, exclude them.

Check #31: Weekly search term review cadence

Negative keyword optimization isn't a one-time task. New irrelevant searches appear constantly as Google's broad match evolves. Set a weekly 15-minute review: sort search terms by cost, identify wasters, add negatives. This single habit prevents more waste than any other optimization activity.

8. Ad Extensions (Assets)

Extensions increase your ad's visual real estate in search results, improving CTR by 10-15% on average. They're free to add and signal quality to Google's algorithm.

Check #32: Sitelink extensions

Every campaign should have at least 4 sitelinks pointing to your highest-value pages (pricing, features, case studies, contact). Include descriptions for each sitelink — ads with sitelink descriptions take up more screen real estate. Update sitelinks seasonally to reflect current promotions.

Check #33: Callout extensions

Callouts are short text snippets that highlight key benefits: "Free Shipping," "24/7 Support," "No Contract Required," "4.8-Star Rating." Add 6-8 callouts per campaign. Google will test and show the best-performing combinations.

Check #34: Structured snippets

Structured snippets list specific features under predefined categories (Types, Brands, Services, Destinations). They add informational depth to your ads. Example: Services — "SEO, Google Ads, Paid Social, Analytics, Creative." If your account has zero structured snippets, you're missing easy CTR gains.

Check #35: Call and lead form extensions

For lead gen businesses, call extensions (click-to-call) and lead form extensions (in-ad form submission) can generate conversions without the user ever visiting your website. Track these as conversions. If your mobile call extension is generating calls but you haven't set up call tracking, you're flying blind on a potentially major conversion source.

9. Quality Score

Quality Score directly impacts your cost per click and ad rank. A Quality Score of 8/10 means you pay roughly 50% less per click than a competitor with a 5/10. Over thousands of clicks, this compounds into massive savings.

Check #36: Quality Score distribution

Export your keyword report with Quality Score columns. Calculate the distribution: what percentage of keywords are 7+, 5-6, or below 5? Healthy accounts have 70%+ of keywords at 7 or above. If more than 20% of your keywords score below 5, you have a structural problem with relevance.

Check #37: Component-level diagnosis

Quality Score has three components: Expected CTR, Ad Relevance, and Landing Page Experience. Each is rated "Above Average," "Average," or "Below Average." Fix "Below Average" components first. Ad Relevance issues mean your ad copy doesn't match keyword intent. Landing Page issues mean the destination isn't relevant or fast enough.

Check #38: Historical vs. current Quality Score

Google stores historical Quality Score, which can drag down your current performance even after you've fixed issues. If a keyword has a long history of low Quality Score, sometimes it's better to pause it, create a new keyword in a fresh ad group, and start with a clean slate.

10. Audience Targeting

Audiences add a behavioral and demographic layer on top of keyword targeting. In 2026, audience signals are essential for feeding the algorithm the right optimization data.

Check #39: Remarketing lists applied

Are you bidding higher on people who've already visited your website? Apply remarketing audiences to Search campaigns in "Observation" mode with positive bid adjustments (+20-50%). These users already know you — they convert at 2-3x the rate of cold traffic.

Check #40: Customer match lists uploaded

Upload your customer email list (hashed) to create Customer Match audiences. Use them for exclusion (don't waste money advertising to existing customers), lookalike targeting (find people similar to your best customers), and upsell campaigns (advertise new products to existing customers).

Check #41: In-market and affinity segments

Google's in-market audiences identify people actively researching products in your category. Apply these as observation audiences to see which segments convert best, then create dedicated campaigns for top performers. Affinity audiences work for awareness; in-market audiences work for conversions.

Check #42: Audience exclusions

Exclude existing customers from acquisition campaigns. Exclude converters from remarketing campaigns (or move them to a separate upsell campaign). Exclude employees and internal traffic. Proper exclusions prevent wasted impressions and keep your CPA calculations accurate.

11. Budget Allocation

Budget allocation determines which campaigns get fuel to grow and which starve. Most accounts allocate budget based on intuition rather than performance data — and it costs them.

Check #43: Budget-to-opportunity ratio

Check impression share for every campaign. If a high-ROAS campaign is losing 40% of impressions due to budget constraints, that's your biggest opportunity. Shift budget from low-ROAS campaigns to fund high-performers. The math is simple: moving $1,000/month from a 2x ROAS campaign to a 5x ROAS campaign generates $3,000 more revenue.

Check #44: Shared budget risks

Shared budgets split spend across multiple campaigns, but Google prioritizes whichever campaign drives the most volume — not the most profit. A high-volume, low-ROAS campaign can consume a shared budget before your high-ROAS campaign gets its fair share. Use individual budgets for campaigns with different performance profiles.

Check #45: Day-of-week and hour-of-day performance

Pull performance data by day of week and hour of day. Many B2B accounts see zero conversions on weekends but still run ads 7 days a week. Many e-commerce accounts convert best on Sunday evenings but allocate budget evenly. Use ad scheduling to increase bids during peak conversion windows and reduce during dead periods.

12. Reporting & Optimization

An audit isn't useful if you don't have the systems to maintain performance over time. The final checks ensure you have the infrastructure for ongoing optimization.

Check #46: Attribution model review

Google Ads defaults to data-driven attribution in 2026, which distributes conversion credit across touchpoints using machine learning. Verify this is enabled. If you've manually set last-click attribution, you're over-crediting branded campaigns and under-crediting top-of-funnel efforts that drive awareness.

Check #47: Weekly optimization cadence

The best account structure in the world decays without maintenance. Establish a weekly cadence: Monday — review search terms and add negatives. Wednesday — check bid strategy performance and adjust targets. Friday — review creative performance and rotate underperformers. Monthly — full performance review against KPIs with reallocation decisions.

How to Use This Checklist

Don't try to fix everything at once. Prioritize by impact:

1. Conversion tracking (#6-10) — Fix this first. Nothing else matters if you can't measure results.
2. Negative keywords (#28-31) — The fastest way to stop bleeding money. Usually saves 15-25% of budget within a week.
3. Landing pages (#20-23) — The highest-leverage optimization. A 1% improvement in conversion rate is worth more than a 10% improvement in CTR.
4. Bidding strategy (#24-27) — Once tracking is solid, switching to the right bidding strategy often cuts CPA by 20-30%.
5. Everything else — Account structure, ad copy, extensions, audiences, budgets. Important, but optimize in order of impact.

Run this audit quarterly. Google Ads is not a "set it and forget it" platform. The accounts that win are the ones that maintain a rhythm of review, analysis, and optimization. The accounts that lose are the ones that launched a campaign 18 months ago and haven't looked at the search terms report since.
