Technical SEO including sitemaps, schema markup, crawlability, and indexing.
Technical SEO is the plumbing beneath your content. Sitemaps, canonical tags, crawl budgets, structured data, indexation controls. Get it wrong and your best content might never appear in search results. Get it right and everything else you do works harder.
Our technical SEO articles go into the details: how to audit your site's crawlability, fix indexation issues, implement schema markup properly, and configure the server-level settings that search engines care about. Written for site owners and developers who want to understand the "why" as well as the "how".

Your SSL padlock doesn't protect against clickjacking, XSS, or downgrade attacks. Security headers do. Our free HTTP Header Inspector grades your headers A to F, traces redirect chains, and flags server version leaks. Here's what to check and how to fix it.
