The Complete PPC Audit Checklist: 44 Points for 2026

What does this PPC audit checklist cover?

This checklist covers every layer of a paid search account, from conversion tracking foundations to competitive positioning. Each point includes what to check, why it matters, and a pass/fail criterion. We’ve structured it in the order we run audits internally: start with tracking (because nothing else matters if your data is wrong), then work through structure, keywords, ads, and optimization.

The checklist applies to Google Ads, Microsoft Ads, and most paid search platforms. For Meta Ads and LinkedIn Ads, the conversion tracking, landing page, and audience sections apply directly. The 2026 version includes new sections on AI-powered bidding, Performance Max, and signal quality that weren’t part of PPC audits two years ago.

• 44 specific audit points with pass/fail criteria
• Organized in execution order (tracking first, optimization last)
• Covers both manual and AI-automated campaign types
• Includes Google Ads, Microsoft Ads, and cross-platform checks
• Updated for Performance Max, broad match, and Smart Bidding in 2026

Is your conversion tracking accurate and complete?

Conversion tracking is the foundation of every PPC account. If your tracking is broken or incomplete, every optimization decision built on top of it is wrong. AI-powered bidding strategies like Target CPA and Target ROAS rely entirely on conversion data. Feed them bad data and they’ll optimize toward the wrong outcomes (Bullseye Strategy, 2026).

Signal quality: The accuracy and completeness of the conversion data you send to Google’s bidding algorithms. Higher signal quality means better automated bidding performance.

1. All conversion actions are firing correctly. Test every conversion action (form submissions, phone calls, purchases, chat initiations) by completing each action yourself and verifying it appears in Google Ads within 24 hours. Check: Are conversion counts in Google Ads within 10% of your CRM/analytics data?
2. Primary vs. secondary conversions are properly classified. Only your core business actions (purchases, qualified leads) should be set as “Primary” conversions used for bidding. Secondary actions (page views, PDF downloads, video plays) should be marked as “Secondary” so they’re tracked but don’t influence Smart Bidding.
3. Google Tag (gtag) or Google Tag Manager is properly implemented. Verify the global site tag fires on every page. Check for duplicate tags, which cause double-counting. Confirm that the conversion linker tag is active in GTM. Use Google Tag Assistant to validate.
4. Enhanced conversions are enabled. Enhanced conversions send hashed first-party data (email, phone, address) to Google to improve conversion measurement accuracy. With third-party cookie deprecation accelerating, enhanced conversions are no longer optional. Verify they’re active in Settings > Measurement > Enhanced Conversions.
5. GA4 and Google Ads data are aligned. Compare conversion counts between GA4 and Google Ads for the same 30-day period. Discrepancies above 15% indicate tracking gaps. Common causes: different attribution models (GA4 defaults to data-driven, Google Ads uses last-click for search), cross-domain tracking issues, or consent mode filtering.

Is your account structure built for performance and control?

Account structure determines budget control, relevance, and reporting clarity. A messy structure leads to budget cannibalization (campaigns competing against each other), poor Quality Scores, and an inability to identify what’s working. The right structure in 2026 balances human control with enough data consolidation for AI bidding to work (Promodo, 2025).

1. Campaigns are organized by goal, not just product. Separate campaigns by business objective: branded search, non-branded search, competitor terms, remarketing, and Performance Max. Each campaign type needs its own budget and bidding strategy. Mixing branded and non-branded in one campaign inflates branded metrics and hides non-branded performance problems.
2. Ad groups contain tightly themed keyword clusters. Each ad group should target one keyword theme with 5-15 closely related keywords. If an ad group has 50+ keywords spanning multiple topics, the ads can’t be specific enough. Google recommends 10-20 keywords per ad group.
3. No campaign cannibalization. Search the Auction Insights report for instances where your own campaigns compete against each other. Common sign: two campaigns bidding on the same keyword with different match types. Use negative keyword cross-matching to prevent internal competition.
4. Campaign naming convention is consistent and descriptive. Names should follow a pattern: [Network]_[Goal]_[Targeting]_[Geography]. Example: “Search_LeadGen_Plumbing_NYC”. Inconsistent naming makes reporting and optimization slower and error-prone.
5. Performance Max campaigns have proper asset groups. Each PMax asset group should target a distinct audience theme or product category. Check that final URL expansion is set to your preference (on for broad reach, off for strict control). Verify audience signals are configured to guide Google’s AI.

Are your campaign settings configured correctly?

Incorrect campaign settings waste budget silently. These are the settings we check on every account because they’re the most commonly misconfigured. One wrong setting can drain thousands of dollars before you notice.

1. Network targeting is intentional. By default, Google Ads includes “Search Partners” and “Display Network” in Search campaigns. Search Partners typically delivers lower-quality traffic at lower CPCs. Display in Search campaigns is almost always wasteful. Decide deliberately whether to include each network based on your data, not defaults.
2. Location targeting uses “Presence” not “Presence or Interest.” The default “Presence or Interest” shows ads to people who are interested in your target location but physically located elsewhere. For most local businesses, this wastes budget on out-of-area clicks. Switch to “Presence: People in or regularly in your targeted locations.”
3. Ad rotation is set correctly for your bid strategy. If you’re using Smart Bidding (Target CPA, Maximize Conversions), set ad rotation to “Optimize.” If you’re running manual CPC and want to A/B test ads, set it to “Rotate indefinitely” and check results after 1,000+ impressions per ad.
4. Language targeting matches your audience. If you’re targeting English speakers in the US, adding Spanish broadens reach but may dilute CTR if your ads and landing pages are English-only. Match language settings to your ad copy and landing page language.

Is your keyword strategy tight and intent-aligned?

Keywords are the targeting mechanism of paid search. The right keywords connect you with people ready to buy. The wrong ones burn budget on irrelevant clicks. With Google expanding broad match behavior in 2025-2026, keyword hygiene is more important than ever. Broad match now matches queries you’d never expect, making negative keywords critical (AdWhiz, 2026).

1. High-spend, zero-conversion keywords are identified. Pull the last 90 days of keyword data sorted by cost descending. Any keyword that spent more than 2x your target CPA without a single conversion is a candidate for pausing or restructuring. These are the biggest budget drains in most accounts.
2. Match types are intentional and documented. Know why each keyword is broad, phrase, or exact match. Broad match should only be used with Smart Bidding and strong negative keyword lists. Exact match gives you the most control. Phrase match is the middle ground. If you can’t explain the match type choice for a keyword, it’s probably wrong.
3. Negative keyword lists are comprehensive and current. Review the Search Terms report for the last 60 days. Flag irrelevant queries and add them as negatives. Maintain shared negative keyword lists for common irrelevant terms (jobs, free, DIY, salary, how to, what is). We add negatives weekly on active accounts. Check our negative keyword list template for a starting point.
4. Search terms report is reviewed regularly. Google now hides a significant percentage of search terms (citing privacy). For the terms you can see, check that they match your intent. If more than 30% of visible search terms are irrelevant, your match types are too broad or your negatives are insufficient.
5. No keyword-level Quality Score issues. Filter keywords by Quality Score below 5/10. These keywords pay a CPC penalty. For each, check: Is the ad copy relevant to this keyword? Is the landing page relevant? Does the keyword have enough historical CTR? Fix or pause keywords with Quality Scores of 3/10 or below.
6. Branded vs. non-branded keywords are separated. Branded keywords (your company name, product names) typically have 30-50% CTR and very low CPC. Mixing them with non-branded terms inflates your average metrics. Separate them into distinct campaigns for accurate performance measurement and budget allocation.

Is your ad copy tested and performing?

Ad copy directly impacts CTR, Quality Score, and conversion rate. Yet it’s the most under-tested element in most PPC accounts. We routinely find accounts running the same ad copy for 6-12 months without a single test variation. That’s leaving CTR and conversions on the table.

1. Every ad group has at least 2 RSAs (Responsive Search Ads). Google recommends at least one RSA per ad group with 10+ unique headlines and 4 unique descriptions. Check Ad Strength indicator. Ads rated “Poor” or “Average” underperform. Aim for “Good” or “Excellent” by pinning high-performing headlines and adding diverse variations.
2. Headlines include the target keyword. The primary keyword should appear in at least 2 of your 15 headlines. This improves ad relevance (a Quality Score factor) and signals to searchers that your ad answers their query. Headlines 1 and 2 get the most visibility, so prioritize keyword inclusion there.
3. Ads contain a clear value proposition and CTA. Every ad needs to answer “why should I click this instead of the competitor below?” Check for: specific pricing or offers, a clear call to action (Get Quote, Book Now, Shop Sale), and at least one differentiator (years in business, guarantee, free shipping).
4. Ad copy matches landing page messaging. The headline, offer, and CTA in the ad should be reflected on the landing page above the fold. Message mismatch between ad and landing page is the #1 cause of high bounce rates on paid traffic. We call this “scent continuity.”
5. Ad testing has a clear plan and cadence. Are you testing specific hypotheses (price in headline vs. not, question headline vs. statement)? Are tests running long enough for statistical significance (typically 200-300 clicks per variation)? Are losing variants being paused and replaced? Without a testing cadence, ad performance stagnates.

Are all relevant ad extensions active?

Ad extensions (Google now calls them “assets”) increase ad real estate on the search results page. Google’s internal data shows that ads with extensions achieve 10-15% higher CTR than ads without them. They’re free to add and only show when Google predicts they’ll improve performance.

1. Sitelink extensions are active and relevant. Add 8-10 sitelinks per campaign pointing to your most important pages (pricing, case studies, contact, specific services). Each sitelink needs a unique description. Check click data: pause sitelinks with zero clicks after 30 days and replace them.
2. Callout extensions highlight key selling points. Add 6-8 callouts: “Free Shipping,” “24/7 Support,” “No Contract Required,” “Since 2015.” Keep them under 25 characters. Callouts don’t link anywhere; they’re text-only trust signals that appear below your ad.
3. Structured snippets are implemented. Choose a header type (Services, Brands, Types, Destinations) and list 4-10 values. Example: “Services: SEO Audits, PPC Management, Content Strategy, Analytics.” These help searchers understand your offering at a glance.
4. Call, location, and lead form extensions are used where relevant. If phone calls matter to your business, add call extensions with business hours. If you have physical locations, connect Google Business Profile for location extensions. Lead form extensions let users submit info without visiting your site, which can reduce CPA by 10-30% for simple lead gen offers.

Are your landing pages built to convert paid traffic?

You can have perfect targeting and compelling ads, but if the landing page doesn’t convert, you’re paying for visits that produce nothing. Landing page experience is also a Quality Score factor, so poor pages increase your CPC. The average Google Ads conversion rate across industries is 7.04% (WordStream, 2025). If yours is below 3%, your landing pages need work.

1. Page loads in under 3 seconds on mobile. Test with Google PageSpeed Insights. A page that loads in 5 seconds has a 90% higher bounce rate than one loading in 1 second (Google, 2023). Mobile traffic typically accounts for 50-70% of paid search clicks, so mobile speed is non-negotiable.
2. Landing page matches ad promise. If your ad says “Get 20% Off Kitchen Remodeling,” the landing page headline should say “20% Off Kitchen Remodeling” above the fold. If the ad says “Free Consultation,” the form or button should say “Book Free Consultation.” Any disconnect between ad and page kills conversion rate.
3. Single clear CTA above the fold. The primary action you want visitors to take should be visible without scrolling. One CTA per page, not five competing options. For lead gen: a short form (3-5 fields max). For ecommerce: prominent add-to-cart button. Remove navigation links that lead visitors away from conversion.
4. Trust signals are visible. Check for: customer logos, review ratings, security badges, phone number, physical address, and guarantee statements. B2B pages should include case study previews or client results. Landing pages without trust signals convert 15-25% lower than pages with them (our A/B test data across 40+ client accounts).

Is your bid strategy appropriate for your data volume?

Bid strategy selection is the highest-impact decision in a PPC account. The wrong strategy wastes budget on every single auction. In 2026, the choice is essentially between manual control (for new or low-volume accounts) and AI automation (for accounts with enough conversion data). Google’s Smart Bidding works well when it has 30+ conversions per month to learn from. Below that threshold, it often performs worse than manual bidding.

1. Bid strategy matches conversion volume. Target CPA and Target ROAS need 30+ conversions per month per campaign to work reliably. Maximize Conversions needs 15+. If you’re below these thresholds, use Maximize Clicks (with a CPC cap) or Manual CPC until you build conversion volume. Forcing automation on low-volume campaigns leads to erratic spending.
2. Target CPA/ROAS targets are realistic. If your actual CPA has been $120 for the last 90 days, setting a Target CPA of $40 will cause Google to drastically reduce spend (or stop spending entirely). Set targets within 10-20% of your actual performance and adjust gradually. Aggressive targets starve campaigns of traffic.
3. Portfolio bid strategies are used where appropriate. If you have 5 campaigns with the same goal and similar CPAs, combine them into a portfolio bid strategy. This gives Google more data to optimize against (150 conversions/month pooled vs. 30 per campaign), which typically improves performance by 5-15%.
4. Bid adjustments are reviewed for automated strategies. When using Smart Bidding, most manual bid adjustments are ignored (device, audience, time of day). The only one that works is location bid adjustments set to -100% (exclusions). Remove other manual adjustments to avoid confusion in reporting.

Are you using audience data to improve targeting?

Audience targeting adds a layer of intent data on top of keyword targeting. Even in search campaigns, audience signals help Google’s bidding algorithms prioritize the right users. With broad match expanding in 2026, audience signals are what keep targeting relevant (Bullseye Strategy, 2026).

1. Remarketing audiences are applied to search campaigns. Add your website visitors as an “Observation” audience on search campaigns. This lets you see how returning visitors perform vs. new visitors and optionally increase bids for them. Remarketing search audiences typically convert 2-3x better than cold audiences.
2. Customer match lists are uploaded and current. Upload your customer email list, phone numbers, or mailing addresses. Google matches these to signed-in users. Use customer match for: exclusions (don’t pay for existing customers to click brand ads), lookalike expansion, and bid adjustments. Update the list at least quarterly.
3. In-market and custom intent audiences are tested. Google’s in-market audiences target people actively researching products in your category. Add relevant in-market audiences as observation layers. Check performance after 30 days: if an audience converts 20%+ better than baseline, set a positive bid adjustment or create a dedicated campaign.

Is your budget allocated to your best-performing campaigns?

Budget allocation is where strategy meets math. Most accounts we audit have at least 20-30% of budget going to campaigns that aren’t profitable. Shifting that budget to proven winners is often the fastest path to better ROAS. The average Google Ads account wastes 25% of spend on irrelevant searches and underperforming campaigns (our data from 100+ audits).

1. No campaigns are consistently “Limited by Budget” without justification. Check the campaign status column. Campaigns marked “Limited by Budget” are missing potential clicks and conversions. If the campaign is profitable, increase its budget. If it’s not profitable, don’t just add budget; fix the underlying performance issues first.
2. Budget allocation reflects ROAS by campaign. Sort campaigns by ROAS or CPA. Your highest-ROAS campaigns should have the most budget headroom. Campaigns with a CPA above your target should have tightened budgets or be restructured. This sounds obvious, but most accounts allocate budget evenly or based on historical inertia rather than current performance.
3. Shared budgets are used intentionally (or avoided). Shared budgets let Google distribute a single budget across multiple campaigns. This helps when you have many campaigns with variable daily spend. But it also means Google might allocate most budget to one campaign on a given day. For campaigns with very different CPAs or goals, use individual budgets.
4. Monthly and quarterly budget pacing is tracked. Check whether you’re overspending or underspending vs. plan. Google can spend up to 2x your daily budget on a single day (and up to 30.4x monthly). If you’re running out of budget mid-month, either reduce daily budgets or cap the most expensive campaigns. Use our PPC report template to track pacing.

Do you know what your competitors are doing in paid search?

Competitor intelligence won’t make a bad account good, but it reveals opportunities you might be missing. The Auction Insights report in Google Ads shows who you’re competing against and how often they outrank you. Pair this with manual searches to see their actual ad copy and landing pages.

1. Auction Insights are reviewed monthly. Check impression share, overlap rate, and outranking share for your top 5 competitors. If a competitor’s impression share is rising while yours falls, they’re either increasing bids/budgets or improving Quality Score. This is your early warning system.
2. Competitor ad copy is monitored. Search your top 10 keywords from an incognito browser every month. Screenshot competitor ads. Note their headlines, offers, and CTAs. If every competitor offers “Free Consultation” and you don’t mention it, you’re at a disadvantage. Differentiate or match table-stakes offers.
3. Competitor landing pages are benchmarked. Click through to competitor landing pages (yes, it costs them a click). Compare page speed, form length, trust signals, and offer structure. If their page loads in 1.5 seconds with a 3-field form and yours loads in 5 seconds with a 9-field form, you know why their conversion rate is higher.
4. Competitor keyword gaps are identified. Use Google Ads’ Keyword Planner or Semrush to find keywords competitors bid on that you don’t. Cross-reference with your conversion data: are there profitable terms you’re missing? Competitor gap analysis typically uncovers 10-20% more keyword opportunities.

How should you use this PPC audit checklist?

1. Start with conversion tracking. Nothing else matters if your data is wrong. Complete all 5 tracking checks before moving to account structure. This typically takes 1-2 hours and often requires developer support for tagging fixes.
2. Work through sections in order. The checklist is structured so that each section builds on the previous one. Account structure affects keyword strategy. Keywords affect ad copy. Ad copy affects extensions. Landing pages affect everything.
3. Score each item as Pass, Fail, or Needs Review. A full audit typically reveals 10-15 “Fail” items in an average account. Prioritize fixes by estimated budget impact: a broken conversion tracking tag wastes 100% of insights, while a missing callout extension might cost you 5% of potential CTR.
4. Run this audit quarterly. PPC accounts decay over time as competitors change, search behavior shifts, and platforms update. Quarterly audits catch drift before it becomes expensive. After major changes (new product launches, budget shifts, agency transitions), run the full audit immediately.
