Technical SEO is the plumbing of your site, the behind-the-scenes work that lets search engines crawl, index and render it.
You do not need to be a developer to cover the basics. A handful of checks prevents the issues that quietly sink rankings.
The core areas
- Crawlability. A correct robots.txt and a clean sitemap.
- Indexing. No accidental noindex tags on key pages.
- Performance. Fast load and mobile-friendly pages.
The basics to get right
- Enforce HTTPS across the whole site.
- Fix broken links and long redirect chains.
- Set canonicals and add structured data.
Note: Technical SEO will not make weak content rank, but technical problems can stop great content from ranking at all.
