A PPC campaign audit is a structured review of your paid search account, campaigns, ad groups, keywords, ads, landing pages, and conversion tracking to find wasted spend, weak targeting, and missed growth opportunities. It matters because even profitable accounts leak budget through loose match types, poor query control, weak ad relevance, and broken measurement. A good audit helps SEMRocket teams and in-house marketers improve return on ad spend without increasing budget.
Start with performance and tracking
Begin with the numbers that define commercial performance: conversions, cost per conversion, conversion rate, impression share, click-through rate, and return on ad spend. Compare campaign performance by brand, non-brand, competitor, and remarketing segments. If these are mixed together, you cannot judge intent or allocate budget properly.
Check measurement before optimization
Audit conversion actions first. Confirm primary conversions are real business outcomes such as qualified leads, booked demos, calls, or purchases. Remove or downgrade soft conversions if they distort bidding. Review attribution settings, duplicate tracking, call tracking, form thank-you triggers, and offline conversion imports. If tracking is wrong, every bid and budget decision will be wrong too.
Review search terms, keywords, and budget waste
Pull the search terms report and look for irrelevant queries, low-intent modifiers, and expensive terms with no conversion history. Add negatives at the right level: account, campaign, or ad group. Then review keyword match types. Broad match can scale, but only when paired with strong negatives, clean conversion data, and sensible bidding controls.
Prioritize by spend and intent
Sort keywords and search terms by cost, then by conversions. High-spend, zero-conversion terms are your fastest savings opportunity. Also look for close variants that should be split into tighter ad groups or moved into dedicated landing page themes. This improves Quality Score, ad relevance, and conversion rate.
Example: a B2B software campaign spends heavily on the keyword “project management tool” in broad match. The search terms report shows clicks from “free project tracker template” and “project management jobs.” Adding negatives like free, template, and jobs, while moving high-intent terms such as “project management software for agencies” into a dedicated ad group with a tailored landing page, can reduce wasted spend and lift lead quality quickly.
Audit ads, landing pages, and bidding strategy
Review each ad group for message match. Ads should reflect the keyword theme, include a clear value proposition, and set the right expectation for the landing page. Test stronger headlines, sharper offers, and more specific calls to action. If one ad group covers too many intents, split it.
Match landing pages to query intent
Landing pages should align with the search term, ad promise, and conversion goal. Check headline relevance, form length, mobile speed, trust signals, and whether the page supports the stage of intent. A generic homepage usually underperforms against a focused landing page built around one offer and one audience.
Finally, review bidding strategy against data volume. Automated bidding needs reliable conversion signals and enough history. If volume is low or tracking is unstable, manual control or tighter campaign structure may outperform. The audit should end with a ranked action list: fix tracking, cut waste, tighten targeting, improve message match, and reallocate budget to the highest-intent campaigns.
