What is technical SEO? A plain-English guide

Technical SEO is the foundation the rest of your SEO stands on — the behind-the-scenes setup that helps search engines crawl, understand, and trust your site. Great content won't rank if the technical basics are broken.

What it covers

• •Crawlability — search engines can access your pages.
• •Indexability — pages aren't accidentally blocked.
• •Speed and Core Web Vitals.
• •Mobile-friendliness.
• •HTTPS security, clean URLs, and structured data.
• •A valid sitemap and correct robots settings.

The good news

Most of this is set up once and maintained. A well-built site handles the technical foundations by default, so you can focus on content and customers rather than plumbing.
