How to Audit Your Site for Free After a Major Core Update
A technical SEO audit is only useful if you can repeat it, track changes, and ship fixes without breaking your site. In this tutorial, you’ll build a complete, developer-friendly audit workflow you can run every month in about an hour, starting from a simple crawl and ending with tested fixes in production. You’ll begin by defining a baseline (indexability, crawlability, performance, and templates), then you’ll prioritize issues by impact and effort so you don’t get stuck in endless checklists. Along the way, you’ll use a free SEO audit tool for discovery, but you’ll validate everything with “source of truth” checks: server responses, robots rules, sitemaps, and page templates. By the end, you’ll have an audit template, a short list of high-leverage checks, and a practical process for collaborating with developers. You’ll also learn how to test fixes safely before deployment, and how to monitor results after changes go live so your audit becomes a reliable system—not a one-time report.
