Technical SEO: Where to Start and What to Fix First

Technical SEO is the groundwork: it makes sure search engines can find, read and trust your pages. Content and links matter little if the foundations are broken.

1. Make sure pages can be crawled and indexed

Check that important pages are not blocked, that a sitemap lists them and that each page has a single, clear canonical address. Search Console shows which pages are indexed and why others are not.

2. Fix speed and mobile experience

Slow, awkward mobile pages lose visitors and rankings. Compress images, reduce unnecessary scripts and check Core Web Vitals reports for real-world results.

3. Structure each page clearly

Use one main heading, logical subheadings, descriptive titles and meta descriptions, and clear internal links between related pages.

4. Add structured data

Structured data labels what a page is about: a business, a service, a FAQ or an article. It helps search engines and AI assistants understand and cite your content accurately.

5. Fix errors and duplicates

Repair broken links, redirect old addresses and avoid duplicate pages competing with each other.

6. Secure and stable hosting

Use HTTPS everywhere and reliable hosting; downtime and security warnings hurt trust.

How to prioritise

Fix what blocks indexing first, then speed, then structure and enhancements. Re-check after each change so you can see what moved the needle.
