What is technical SEO? Technical SEO is the work that helps search engines crawl, understand and index your site — things like speed, mobile-friendliness, a clean site structure, secure HTTPS, and proper indexing. It’s the foundation that lets your content and off-page authority actually rank.
What does technical SEO include?
- Fast load times and good Core Web Vitals
- A mobile-friendly, responsive design
- Crawlable, indexable pages (no accidental blocks)
- A logical site structure and internal links
- Secure HTTPS and a clean, error-free site
Why does technical SEO matter?
If search engines can’t crawl, render or trust your site, even great content won’t rank. Technical SEO removes the obstacles so your relevance and authority can do their job.
How do I check my technical SEO?
Free tools like Google Search Console (coverage and Core Web Vitals reports) and PageSpeed Insights surface most issues — crawl errors, indexing problems, speed and mobile usability.
Do I need to be technical to fix it?
Some fixes are simple (compress images, fix broken links); others need a developer. The key is knowing what’s broken, then prioritising the issues that actually affect crawling, speed and indexing.
