The Importance of SEO
Good SEO, or Search Engine Optimization, is important for your site to appear on search engines. Search companies such as Google, Yahoo, and Bing look at several aspects of your site to determine where you appear in their search results. They look for relevant terms, time your visitors stay on the site, mobile friendliness, and security, as well as many other options.
Basically they are the middle man, and make sure that your site has what their users want to make sure that they keep using their service. A search engine won’t recommend sites that don’t meet their user expectations. Before modern search engines existed, there were directories that featured sites that had to be manually added. Now there are automated processes that the crawl through your site content looking for relevant information, a mobile friendly layout, check for security certificates, and page load speeds.
