Usually, the phrase ‘Technical SEO’ refers to optimizing your website for crawling and indexing, but it can also include any technical process meant to improve search visibility and performance.
Technical SEO is an ever changing field, covering everything from xml and html sitemaps, meta tags, JavaScript indexing, internal linking, structured data (schema) implementation, and more.
Technical SEO is defined by configurations that can be implemented to your website and your server environment. All technical SEO strategies have an impact on search engine crawling, indexing and ultimately your positioning or ranking.
SEO has always entailed driving high-quality traffic through organic search, and because of the ever changing landscape associated with how searchers search the internet it is ever clearer that technical SEO is a necessity, not an option.
