Facebook has made its content (groups, wall posts, events, discussion topics, etc.) accessible to search engines. This is an excellent opportunity for those in pursuit of SEO success.
Facebook could now be a major source of search engine optimized content. In fact, FB content is already driving substantial traffic from organic searches. The Website Magazine Facebook page has seen a dramatic increase in visitors and page views in the past few days and I expect that trend to remain consistent in the future.
If you're interested in search engine optimization for your personal brand or your website, I would highly advise that you get started building Facebook pages, creating groups and participating fully in that social network. The rewards will be many!
