Google Ads Audit Checklist for Small and Midsize Businesses

What should a Google Ads audit cover?

A Google Ads audit is a structured review of an account that identifies what is working, what is broken, and what order to fix things in. For small and midsize businesses, the most common findings are in four areas: conversion tracking accuracy, campaign structure, search term and match type discipline, and bidding logic. Fixing these in the right order produces the fastest improvement in account efficiency.

Step 1: Verify conversion tracking before anything else

Conversion tracking is the foundation every other setting depends on. If the account is optimizing toward the wrong events, every bid strategy, budget decision, and optimization call is compromised. Check this first, before reviewing campaign settings or performance numbers.

• –Open Tools and Settings, then Conversions. List every active conversion action.
• –Identify which actions are set as Primary (used for Smart Bidding) versus Secondary (observation only).
• –Check whether each primary conversion represents a genuine business outcome: a real lead, a purchase, a qualified phone call. If it is a page view, session duration, or soft micro-conversion, Smart Bidding is optimizing toward the wrong signal.
• –Compare Google Ads conversion counts to CRM lead counts for the same 30-day window. A significant discrepancy means double-counting or tracking gaps.
• –Check conversion tag status in the Tag Assistant or Google Tag Manager. Tags that show "No recent conversions" on high-spend campaigns need investigation.

Step 2: Review campaign structure

Campaign structure determines how budget is allocated, how bidding strategy is applied, and how clearly you can read performance data. Poorly structured accounts mix unrelated intent types, geographies, or product categories in the same campaign, making it impossible to optimize any of them well.

Step 3: Search term and negative keyword review

Search terms are the most direct evidence of where budget is going and whether it is being spent on relevant queries. This is the single most impactful thing to review regularly in any account.

• –Pull the search terms report for the last 90 days. Sort by cost. Read the top 100 queries. Flag any that do not represent a realistic customer for your business.
• –Group the flagged queries into themes — informational, wrong geography, wrong product, competitor-research intent — and add each theme as a negative keyword group.
• –Check whether the negative keyword list has been updated in the last 30 days. If not, no one has been reviewing search terms.
• –Look for brand name queries appearing in non-brand campaigns. Add brand terms as negatives to non-brand campaigns and run a separate brand campaign.
• –Check match type distribution. If most keywords are broad match with few negatives, the account has limited control over query quality.

Step 4: Bidding strategy assessment

Bidding strategy should match the account's data volume and conversion quality. The most common mistake is using Target CPA or Target ROAS before the account has enough clean conversion data for the algorithm to learn from, or setting targets that are unrealistic given actual historical performance.

• –Check the current target against the 30-day actual average. If the target CPA is set to $50 but the 30-day average is $120, the algorithm is constrained in a way that reduces volume without improving efficiency.
• –Check for campaigns that show "Limited by target." This usually means the target is too aggressive relative to actual performance.
• –Check whether budget is the binding constraint or the target. A campaign limited by budget and a campaign limited by target need different fixes.

Step 5: Landing page alignment

Landing page relevance affects Quality Score, which affects CPC. More importantly, it affects conversion rate. Traffic that arrives at a page mismatched to the ad intent will not convert regardless of how well the campaign is set up.

• –For each top-spend ad group, check the destination URL. Does the page specifically address the intent of the keywords triggering that ad group?
• –Check the page load speed on mobile. A page that takes more than 3 seconds to load on mobile loses a significant portion of paid traffic before the page renders.
• –Is there one clear call to action? Multiple competing CTAs dilute conversion intent.
• –Does the page headline match the ad copy? Message mismatch is one of the fastest ways to reduce landing page conversion rate.

Step 6: Ad copy and quality

Ad copy quality affects click-through rate, which affects Quality Score, which affects CPC and auction eligibility. Beyond mechanics, ad copy that does not match search intent reduces conversion rate even for clicks that land.

• –Check whether Responsive Search Ads have at least 8 to 10 headline variants and 3 to 4 description variants. Fewer variants limit Google's ability to find the best combinations.
• –Review ad strength ratings. "Poor" or "Average" ratings indicate insufficient asset variety or low relevance.
• –Check whether at least one headline includes the primary keyword for the ad group.
• –Review whether ad extensions (assets) are in use: site links, callouts, structured snippets, call extensions. Accounts without extensions lose real estate and quality signals.

Priority action framework

Not all audit findings carry equal weight. This is the sequence that produces the fastest improvement:

1. Fix conversion tracking first. Everything else is unreliable until this is confirmed accurate.
2. Separate brand from non-brand. This one structural change clarifies performance data immediately.
3. Clean up search terms. Add negatives for obvious waste categories. This reduces irrelevant spend immediately.
4. Review bidding strategy against data volume. Move to the appropriate strategy for the account's conversion volume.
5. Fix the worst landing page alignment issues. Start with the highest-spend ad groups.
6. Improve ad copy variety and extension coverage. This is last because it has the lowest immediate impact on budget efficiency.
