SEO often involves improving the quality of the content, ensuring that it is rich in relevant keywords and organizing it by using subheads, bullet points, and bold and italic characters. SEO also ensures that the site’s HTML is optimized such that a search engine can determine what is on the page and display it as a search result in relevant searches. These standards involve the use of metadata, including the title tag and meta description. Cross linking within the website is also important.

The leading search engines, such as Google, Bing and Yahoo!, use crawlers to find pages for their algorithmic search results.

Directory and DMOZ, two major directories which closed in 2014 and 2017 respectively, both required manual submission and human editorial review.[40] Google offers Google Search Console, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that are not discoverable by automatically following links[41] in addition to their URL submission console.[42] Yahoo! formerly operated a paid submission service that guaranteed crawling for a cost per click;[43] however, this practice was discontinued in 2009.
