7 Google Ads Mistakes Costing Your Business Money

After auditing hundreds of Google Ads accounts managing over $3M in annual ad spend, patterns emerge quickly. The same mistakes show up in nearly every account we review, and they silently drain budgets while producing underwhelming results.

Here are seven of the most common issues and how to address each one.

1. Running broad match keywords without guardrails

Broad match has become more capable with Google's AI improvements, but it still requires tight controls. Without negative keyword lists and careful bid strategies, broad match campaigns burn through budget on irrelevant searches. We recommend starting with phrase match and exact match, then expanding to broad match only after building a thorough negative keyword list from search term data.

2. Ignoring search term reports

The search terms report shows exactly what queries triggered your ads. Many advertisers check it once during setup and never return. Review search terms weekly for the first 90 days, then biweekly after that. Add irrelevant terms as negatives and look for high-converting queries to add as exact match keywords.

3. Sending all traffic to the homepage

Your homepage serves visitors at every stage of awareness. A search ad targeting a specific service should land on a dedicated page for that service. Purpose-built landing pages consistently beat a generic homepage, because the message matches what the visitor actually searched for.

4. Not tracking conversions properly

Without conversion tracking, Google's bidding algorithms have no data to optimize toward. Yet we find broken or missing conversion tracking in roughly 40% of the accounts we audit. Verify your tracking setup monthly: submit test leads, check that conversions fire in Google Ads, and confirm the numbers match your CRM.

5. Setting and forgetting bid strategies

Automated bidding strategies like Target CPA and Maximize Conversions need calibration. If your target CPA is too aggressive, Google will throttle impressions. If it is too loose, you will overpay for each lead. Start with Maximize Conversions to gather data, then switch to Target CPA once you have at least 30 conversions in a 30-day window.

6. Writing generic ad copy

Ads that say "We offer great service" compete against ads with specific numbers and outcomes. Include concrete data: response times, years of experience, customer count, or pricing. Responsive Search Ads give you 15 headline slots. Use them to test specific value propositions rather than repeating vague benefits.

7. Overlooking ad extensions

Sitelinks, callouts, structured snippets, and call extensions increase your ad's footprint in search results without additional cost. Google uses extensions as a ranking signal for Ad Rank. Accounts with complete extension coverage consistently see higher click-through rates and lower cost-per-click compared to bare ads.

Start with an audit

The fastest way to identify which of these issues affect your account is a structured audit. We review account structure, bidding strategy, keyword targeting, conversion tracking, and ad creative as part of every new engagement.
