Technical SEO
Technical SEO is where Search Engine Optimisation meets the build. It is the work of making sure a site can be crawled, rendered, understood and trusted when the CMS, templates, JavaScript, redirects and platform architecture get in the way. General SEO can deal with demand, content and reputation. This category is for the problems caused by the website itself.
Below you will find a subset of articles from my blog specifically about technical SEO implementation and related technical SEO for JavaScript applications. This is an area I have worked with for many years, and it has been a regular subject in my writing. There are twenty‑five articles collected together for you below.
