PPC audit checklist for small businesses

A thorough PPC audit evaluates your account structure, conversion tracking accuracy, search query intent, negative keyword lists, and landing page conversion rates to eliminate wasted ad spend. For most small to mid-sized businesses, running a systematic audit every 90 days reveals that 15 to 30 percent of the monthly ad budget is disappearing on non-commercial search queries or misconfigured bidding settings.

Whether you manage campaigns yourself or pay an external agency, auditing your active accounts keeps your advertising profitable. This step-by-step checklist walks through the points worth checking to stop budget leaks and lower customer acquisition costs.

To check your tracking setup before beginning your audit, follow our guide on how to set up Google Ads conversion tracking.

Phase 1: Conversion tracking accuracy audit

You cannot optimize what you measure incorrectly. If your conversion data is flawed, every automated bidding decision Google makes is based on faulty signals.

Check these four conversion settings immediately:

Primary versus secondary conversion status: Review your conversion goals in Google Ads. Ensure only high-value actions (completed quote forms, phone calls over 60 seconds, or completed transactions) are marked as Primary. If page views or newsletter signups are set to Primary, change them to Secondary so smart bidding algorithms do not bid on cheap clicks that never buy.

Lead counting method: Confirm that lead generation actions use the One counting setting rather than Every. If a user clicks your submit button three times in rapid succession, your account should record a single lead.

Conversion recency check: Check the Last conversion column. If a high-volume lead form has recorded zero conversions over the past 30 days while ad spend continued, your tracking tag is broken or disconnected.

Enhanced Conversions verification: Check whether Enhanced Conversions is active in your conversion settings. Enabling hashed first-party data matching recovers conversions that would otherwise be blocked by browser privacy restrictions.

Phase 2: Campaign settings and geographic targeting audit

Google often hides default campaign settings that encourage overspending on low-intent traffic.

Audit these settings across every active campaign:

If your campaign currently targets Presence or interest, someone researching your city from another state or country can trigger your local service ads. Switching to Presence immediately eliminates geographic budget waste.

Phase 3: Keyword intent and search terms audit

The search terms report reveals the actual words users typed before clicking your ads. This is where most ad waste is uncovered.

Audit your search terms report

1. Open your Search Terms report and set the date range to the past 30 days.
2. Sort the table by Cost in descending order.
3. Identify queries that accumulated significant spend with zero conversions. If a query cost $150 and generated no leads, examine whether the search intent was commercial or informational.
4. Add non-commercial search terms directly to your negative keyword lists.

Check match type distribution

Review your keyword match types. If your account relies entirely on broad match keywords without extensive negative lists, Google is matching your ads to broad queries that dilute your budget.

Ensure core commercial terms use phrase match (in quotation marks) and exact match (in brackets). Learn how to organize negative lists in our guide on negative keywords.

Phase 4: Ad creative and asset audit

Weak ad copy leads to low click-through rates, which depresses your Quality Score and inflates your cost per click.

Examine these creative components:

Ad strength and asset variety: Review your Responsive Search Ads. Each ad should include at least 8 to 12 distinct headlines and 3 to 4 descriptions. Avoid repeating the same words across multiple headlines. Write specific headlines that highlight pricing and licensing credentials.

Headline message matching: Ensure Headline 1 and Headline 2 repeat the primary keyword of the ad group. If the user searches for commercial roof inspection, the ad headline must state Commercial Roof Inspection.

Ad assets: Check that call assets and sitelinks are active and approved. Accounts that utilize full ad assets occupy more visual space on mobile screens, increasing click-through rates without raising click costs.

Phase 5: Bidding strategy and budget allocation audit

Your bidding strategy must align with your account's historical conversion volume.

Check these bidding variables:

Evaluate your automated bidding strategy. If you run Target CPA or Target ROAS, confirm that the campaign generates at least 30 conversions per month. Automated bidding on accounts with fewer than 15 monthly conversions often causes erratic bid swings because the algorithm lacks sufficient data to calibrate bids.

Examine your Lost Impression Share due to Budget. In your campaign columns, add Search lost IS (budget). If this metric exceeds 20 percent, your daily budget is too low for your keyword bids, causing Google to pause your ads mid-day. Lowering bids can help your budget last throughout the full business day.

Verify brand separation. Ensure your brand name searches are separated into a dedicated branded search campaign with a low Target CPA, rather than mixed into general service campaigns where they mask underperforming non-brand keywords.

Phase 6: Landing page experience audit

A well-targeted ad will still fail if the landing page experience creates friction for mobile users.

Evaluate your destination pages against three criteria:

Mobile load speed: Test your landing page on Google PageSpeed Insights. If mobile load time exceeds three seconds, compress images and eliminate unnecessary scripts.

Above-the-fold call to action: Verify that mobile visitors can see a prominent click-to-call button or quick quote form without scrolling down the screen.

Relevance and message continuity: Check that the headline on your landing page mirrors the ad copy that drove the click. Read our guide to PPC landing pages that convert for layout examples.

If your audit reveals multiple broken settings and your campaigns continue to underperform, consult our diagnostic guide on why your Google Ads are not working.

How to document your audit findings and build an action plan

A PPC audit is only useful if it results in concrete operational changes. When completing your review, categorize findings into three implementation tiers:

Immediate fixes: These are urgent setting corrections that stop money from leaking right now. They include disabling display network expansion on search campaigns, switching location targeting from Presence or interest to Presence, and repairing broken conversion tracking tags. Complete these within 24 hours.

Weekly optimization tasks: These tasks include adding negative keywords identified in your search terms report, writing new responsive search ad headlines to replace low-performing variations, and testing click-to-call buttons on mobile landing pages.

Strategic changes: These changes require careful planning over 30 to 60 days. They include restructuring ad groups into tighter themes, building dedicated landing pages for specific services, and transitioning from manual CPC bidding to Target CPA once conversion volumes support automated smart bidding.
