Technical SEO agencies
Technical SEO is the work that lets search engines crawl, render and index a site correctly: site architecture, crawl budget, internal linking, structured data, JavaScript rendering, Core Web Vitals and index control. It matters most for large, complex or recently rebuilt sites where a defect can suppress thousands of pages.
Questions worth asking
- Which crawling and log-analysis tools do you use, and can you show a sanitised audit?
- How are findings prioritised and who implements the fixes?
- How do you validate a fix once it is shipped?
