Welcome to the Q&A Forum

_ Is it better to keep things status quo and not give Google the data or potentially introduce a new signal to Google that might be negative if CTR is not high enough?_ If you don't add it, the signal could look as a 0 to Google (no social sign of life)... that could be finally worst than having few +1. I think that we have to forget SEO has it was since few months ago, and start thinking SEO-Socially. SEO and SM are getting closer, and surely Social Signals are playing a big part in the rankings, directly or not. What is sure, is that if you have a great site, with great contents that answer to users needs, has all to gain with the social sharing. So, yes, start play the social game. But don't fall in the opposite risk: to forget traditional SEO tactics, because they still count a lot. The philosophy is that Search Marketing has become a wider playfield, with more tactics and web marketing disciplines that influence it. The real secret is to create a coordinated internet marketing strategy and stop thinking one tactic at the time.
