Technical SEO is a rigorous and time-consuming practice, and avoiding it can be costly. If search engines can’t find & crawl your website efficiently, you won’t rank well.
Technical SEO does not, for most small & medium businesses, require a dedicated full-time resource. So naturally, outsourcing to a freelancer or agency to get ad-hoc work done makes sense.
If you want to outsource your technical SEO to experienced agencies, you've landed in the right place. I've compiled a list of the 18 best technical SEO agencies worldwide that you can consider for your business.
What does a technical SEO agency do?
Technical SEO is a branch of search engine optimization that ensures a website is easy for search engines to properly access, crawl, and index. It primarily concerns the “behind-the-scenes” elements of your website and covers things like robots.txt files, indexing, XML sitemaps, loading times, and more.
It's everything you need outside of the other core areas of SEO: content & link building.
