When Google and other search engines' crawlers come across a given website, among the various aspects of the site they assign ranks to as part of the process that will eventually determine its placement in generated SERPs is its "authority." Both the overall domain of the website and each of its pages receive a grade on whether it can be considered to be a reliable and authoritative resource for information about the industry the website presents itself as dealing in. The chances a search engine will award a high ranking for domain authority are proportional to the number of websites elsewhere that are maintaining quality backlinks pointing to it. Any website that is trying to become successful in a competitive online environment should always have a presence on social media. It would be considered extremely unusual if a company tried to do business without both a Twitter account and a Facebook profile because they are extremely easy to set up. They would offer the most direct and baseline methods of exposing a brand to potential customers and providing them a direct path toward the website itself. The owner of a website for a business would obviously need to make great efforts to nurture their site's content and optimize it for search engines so that it can be presented to large crowds as a resource worth discussing and linking to, but the website's representative profiles on social media will always provide a baseline amount of authority. In an odd phenomenon that can occur with more out-of-date websites that have never been properly optimized, their own Facebook profiles can be placed higher than themselves in SERPs generated from queries directly searching for those sites. This can be explained as an outcome of Facebook's own prominent status as a permanent fixture of Internet culture and online business; Facebook is innately well-optimized for search engines, so any of the profiles hosted on it will inevitably be seen and recognized by search crawlers as well-optimized by association. A website placing underneath its own Facebook page obviously and desperately needs to improve its SEO to succeed.
