What do I mean by Accessibility in Search Engine Optimisation? Google tells us that websites should be built for people and not search engines, yet to get traffic some form of SEO needs to be carried out. Accessibility in my eyes looks at the coding of the website, making it accessible to search engines and people such as those with disabilities.
What do I mean by Back links in Search Engine Optimisation? Back links are the links from other websites, they can be helpful and if sourced wrongly harmful to you websites SEO work.
What do I mean by Content in Search Engine Optimisation? There is a term Content is King and that is correct, yet you still need the queen (coding) and a few princes (back links) for your website to rank well.
