What Is Search Engine Optimization?

Search Engine Optimization (SEO) is the process of understanding searcher behavior and audiences, and optimizing web content to deliver a relevant experience. It includes essential elements of technical web mastering, including providing search engines with directives, annotations, and signals for them to efficiently crawl, index and therefore rank a web page. This process ultimately results in increased search traffic and revenue.

SEO can be boiled down to three core elements, or functions: crawling (discovery), indexing, and ranking.

What Is Technical SEO?

Technical SEO is defined by configurations that can be implemented to the website and server (e.g. page elements, HTTP header responses, XML Sitemaps, redirects, meta data, etc.). Technical SEO work has either a direct or indirect impact on search engine crawling, indexing and ultimately ranking. As such, Technical SEO doesn't include analytics, keyword research, backlink profile development or social media strategies.
