An SEO audit is not a report card. It's a diagnostic — designed to answer one question: why isn't this site ranking where it should be?
For general contractors, the answer almost always lives in one of four layers. Miss a layer and you'll fix symptoms while the root cause keeps dragging you down.
The Four Audit Layers
- Technical health: Can Google crawl, index, and render your pages correctly? Issues here — broken links, duplicate URLs, missing sitemaps, slow load times — prevent rankings regardless of how good your content is.
- On-page signals: Are your service pages telling Google what you do, where you do it, and for whom? Title tags, H1s, body content, and internal linking all factor in here.
- Local SEO signals: Is your Google Business Profile complete and optimized? Are your NAP (name, address, phone) citations consistent across directories? Does your site include geo-targeted service area pages?
- Authority and trust: Do other credible websites link to yours? Does your backlink profile look natural? Are there any toxic links pointing at the site that could be suppressing performance?
Each layer builds on the one before it. A site with strong content but technical crawl errors will underperform. A site with great local signals but zero authority will plateau. The audit tells you which layer is the current bottleneck.
One important note: an audit is not the same as a checklist. A checklist tells you what to build. An audit tells you what's broken — and broken things need different fixes than missing things.
