A technical audit isn't about chasing a perfect score; it's about removing the things that quietly hold a site back — pages search engines can't read, links that go nowhere, a broken padlock, an ugly share preview. This checklist walks the full surface in the order that matters, and points you at a tool to run each check on demand.
The signals search engines read straight from the HTML. Get these right and crawlers understand the page; get them wrong and even great content underperforms.
Before a page can rank, it has to be found and allowed. Two files control this, and both are common sources of accidental, traffic-killing mistakes.
Make sure you're not accidentally blocking crawlers (the dreaded Disallow: /), and that your sitemap is declared.
Confirm it exists, lists your important URLs, stays under the 50,000-URL / 50MB limits, and uses <lastmod> so crawlers prioritize fresh content.
Broken links waste crawl budget and frustrate users; sloppy redirects leak link equity and slow loads.
Security is a ranking and trust factor — and a broken padlock scares users away.
http:// resources on an HTTPS pageOften skipped, but it's what determines whether your links get clicked when shared. Open Graph and Twitter Card tags control the title, description, and image that appear in social feeds and chat apps.
