Search Engine Optimisation (SEO) has matured into a number of key disciplines.
Technical SEO is focussed on the on-site factors that assist search engines in crawling and indexing your web-based resources correctly so they can be served in the results pages (SERPs) for the most appropriate searches.
In general terms, this involves ensuring all content can be found and is tagged correctly.
Technical SEO is distinct from other SEO practices such as back-linking and content creation, but creates the foundation to maximise their effectiveness.
