A Technical SEO Checklist in December 2019 is a key strategy to all website optimisation. Too many SEOs concentrate their attention on content and backlinks but leave technical SEO because it is not sexy to carry this out. I recently heard a great saying from a good friend of mine called Andrew Halliday:-
You wouldn’t build a million dollar house on quicksand, so don’t build a million dollar website on poor foundations
This saying is so true and technical SEO is the foundations of your website. This element of works is about how easy the spiders crawl your site, index your pages and performance of the site build.
