If you follow me on Twitter and then search for email marketing, Blue Sky Factory will rank higher than it would if you didn’t follow me on Twitter, because I share stuff from BSF on Twitter, and Google’s algorithm assumes that because we’re connected, my voice as a social connection should be more influential to your search than some SEO’s optimizations.
Let that sink in for a moment. That’s monumental for three reasons.
1. Influencers who have large social networks are now causing search engine adjustments based on what they share.
2. “#1 ranking for a keyword” on Google is less meaningful now if the #1 is displaced by social sharing influence.
3. If you’re marketing something, there’s now a direct incentive to build your network as large as possible among your prospective customers. Size matters.
