Search Engineering vs Social Marketing
Lot has changed since rise of instant traffic generators like Digg, StumbledUpon came and then onwards Facebook/Twitter established as de-facto place for social marketing. With facebook/twitter came in the concept of Social Marketing and it really added whole new dimension to Internet Marketing. Marketers saw instant, huge ROI which smashed their wildest expectations. We saw incoming traffic from Facebook/Twitter reach heights beyond regular traffic from search engines.
However important factor which still keeps Search Engine Marketing in run is consistency. In a longer run your traffic from Search Engine will still be more than your one day wonder from Facebook/Twitter. So it still matters to be in top ten results on Google – marketers know this and as a result Google Adwords is raking in cash for Google even after Facebook use reached its peak.
