Before the era of Web 2.0, search engine optimization (SEO) consisted mostly of search engine indexing, Web directory listings, keyword rich content, and backlinks. Social media has evolved the art of ranking high on search engines. Sharing content from the blogosphere, on social media platforms, is the next thing in SEO. The sharing of web pages on these social networks is called social bookmarking.
The main job of search engines is to provide the Web pages with the best content that best match the keywords users enter. Countless search engine optimizers are working hard to manipulate these online engines.
The mechanics of these search engines have added social media to their search engine ranking algorithms. Their only concern is displaying the most popular content. In their eyes, if it's popular it must be important. This is why “Web 1.5” had everyone scrambling for backlinks.
Social bookmarking, or “liking,” as Facebook would call it, can also have comments embedded, which means there is feedback from users. When even more people share the Web page it's like voting for the page.
Social networks also ensure that the links to Web pages are safe and spam-free. It's only natural that search engines would use social bookmarking when social media is doing all of the legwork. For these reasons, socially bookmarked pages rank very high on search engines, especially the most recent blog posts.
Having social media profiles on social networks gives your company a more professional and up-to-date image. A good Web designer can make sure social bookmarking links, called buttons, are on all of your public Web pages for users to share on social networks.
Make sure your content is original; unique content gives your website authority. Not only will this boost your search engine rankings for your website and Web pages, but also for your social network profiles.
