Activity generated on social media sites has no impact on the optimization of the page itself outside of its own website, but it can have a significant impact on SEO’s most important external link building.
Most social media sites are user-contributed content, you can freely leave the URL, but for SEO personnel, bringing links is not as simple as posting and leaving URLs, most of the places where users can leave URLs have been made, and the URLs left behind cannot become links in the ordinary sense. so, the use of social media websites to build external links is indirect, you need to let other users on social media pay attention to your brand, product, or topic, and then users on their own websites, blogs again to discuss and mention your website, to bring links.
it is precisely because there is such a step in the middle, so the ordinary interaction on social media websites is difficult to bring links, and only which become hot topics, such as topics that are forwarded thousands of times on Weibe and are hotly discussed in forums, can bring a lot of traffic and valuable external links. The external link advantage brought about in this way is obvious, very natural, completely user-actively contributed, and a one-way link. There are also links to high-authority domain names.
Interaction and word-of-mouth communication
Marketing on a social media website, the most important thing is to interact with other users, build brand awareness, contribute to word-of-mouth communication. Accumulate several powerful social media website accounts with many fans, when the website has any new topics and products, a microblog or a post can quickly reach thousands of people, including many influential people on the Internet, and there is no shortage of people who manage the website and blog themselves, if they can promote it twice, your information can spread quickly, in this way, your articles and links will appear on more websites, and your website will have more people discussing. The resulting impact is difficult to calculate precisely, but it can affect rankings and SEO effectiveness overall.
New form link flow
most of the links left on social media sites are not normal links that search engines directly use to calculate weights. but the number of social media site users is huge, and the number of links left behind is also staggering, as if new forms of linking and weight flowing patterns have been formed. for example, google publishes links in twitter and Facebook that are counted in the ranking algorithm.
the huge flow of links on social media sites is bound to be checked by search engines and is unlikely to remain indifferent. the goal of search engine ranking is relevance, authority, and usefulness. links posted by users of social media sites are a form of practicality. While these links are unlikely to pass weights like normal links, they are likely to have become or will become a new ranking signal, an adjunct to ordinary links.
