The Google Ads audit checklist for small businesses

Even well-set-up accounts develop problems over time. Google's automated bidding shifts spend. Smart Bidding strategies cap out. New campaign types like Performance Max take over more of the account. Conversion tags decay. The result is that a healthy account three months ago can quietly be the source of half your wasted budget today.

An audit isn't about pausing everything that looks expensive. It's about making sure every dollar in the account is doing a job you understand — and that the conversions you're reporting actually reflect business outcomes, not just clicks.

Start here. Every other number in the account flows from this. If conversions are over- or under-counted, every "optimisation" you make will be based on bad data.

• Open Tools → Conversions. List every active conversion action and ask: does this represent something the business actually cares about?
• Check the conversion category (Purchase, Lead, Sign-up). Only one or two should be marked Primary. Everything else should be Secondary so it informs reporting without driving bids.
• Look at attribution model. Data-driven attribution is usually the right default; last click flatters branded campaigns and undervalues upper-funnel work.
• Verify deduplication. If you have a Lead conversion and a Purchase conversion, make sure a single buyer isn't being counted twice for the same journey.
• Cross-check with your CRM, store, or product analytics for one full week. If Google reports 80 conversions and your CRM has 40, find the gap before changing anything else.

Most accounts accumulate campaigns the way garages accumulate boxes. The audit moment is when you decide what stays.

• Group campaigns by intent: brand, non-brand search, shopping, Performance Max, display, video. Note total spend for each.
• Brand campaigns: if you're the only meaningful bidder on your brand terms, consider how much you really need to spend. Most small businesses overspend here.
• Performance Max: check the asset-group level reporting. If one asset group is eating 60%+ of the budget with weak conversion quality, separate it.
• Look for campaigns spending under $5/day. They rarely accumulate enough data to optimise — consolidate or pause.
• Look for campaigns with budgets capped daily. Either raise the cap or accept you've decided this isn't a priority and pause it.

This is the section that pays for the audit. Work top-down: campaign, ad group, keyword, search term.

• Filter the last 30–90 days by spend descending. Anything over $200 with zero conversions deserves a closer look — not necessarily a pause, but an explanation.
• Open the Search terms report. Look for irrelevant queries, job-seeker terms, competitor names you don't want to pay for, and free-intent queries ("free", "jobs", "how to do X yourself"). Add to negative keyword lists.
• Check device performance. Mobile traffic from display partners is a common silent leak.
• Check geography. You're probably paying for clicks in regions you don't sell to.
• Audit audience exclusions. Existing customers and current users shouldn't see your prospecting ads.

• Match types: broad match is fine when paired with strong negatives and Smart Bidding, but check that search terms still match intent. If not, tighten to phrase match.
• Quality Score: filter for keywords spending money with QS under 5. Low QS usually means ad relevance or landing page experience needs work — and it's costing you on CPC.
• Bidding strategy: tCPA and tROAS only work when conversions are honest (step 1) and there's enough volume. If a campaign converts fewer than ~15 times per month, consider Maximize Conversions with a cap instead.
• Ad rotation: check that you have at least 3 ads per ad group, and that underperformers have been paused recently.

• Open a few top-spending ads and click through. Does the landing page match the ad's promise word-for-word?
• Mobile load time under 3 seconds. Slow pages quietly destroy paid performance.
• Check that responsive search ads have at least 8 headlines and 3 descriptions, with strong asset ratings.
• Sitelinks, callouts, structured snippets, lead form extensions — every campaign should have at least sitelinks and callouts active.

The most common audit mistake is stopping at Google Ads metrics. A campaign showing a 3x ROAS in Google Ads can still lose money if the customers it brings in churn quickly, refund often, or buy only once. The most important part of any audit is to look at campaign performance alongside the business signals that matter: pipeline created, qualified accounts, repeat orders, retained users.

For an early-stage business this can be as simple as exporting last quarter's closed-won deals or paying customers, tagging the original source where possible, and asking: which campaigns are creating the kind of customers we actually want more of?

Every audit should produce a short written summary: what you found, what you changed, what you want to revisit in 30 days. Without a paper trail, the next audit starts from scratch. With one, you build a compounding view of the account.

• Top 3 wasted-spend findings and the change made
• Top 3 opportunities (campaigns to scale, keywords to lean into, audiences to test)
• Open questions to verify with another data source (CRM, store, product analytics)
• Next audit date (we recommend monthly for active accounts, quarterly at minimum)

For most small businesses spending under $10k/month on Google Ads, a full audit once a quarter plus a 30-minute monthly check on the highest-spend campaigns is enough. Above $10k/month, monthly audits start to pay for themselves quickly — the difference between catching a runaway Performance Max campaign in week one vs week four is often the entire month's wasted budget.

Running this audit manually is doable, but it's the kind of work that tends to slip — exactly when budget pressure makes it most important. Zaynforce is a growth intelligence platform that connects ad platform data (including Google Ads) with customer journey and revenue signals, so the audit becomes a continuous view instead of a quarterly project. Founders and small teams use it to make sure paid spend stays connected to real business outcomes, not just platform-reported conversions.
