I Just sat through Google’s +1 implementation seminar.
I had some good takeaways that I will share – we should test these as well to see the takeaways and value:
+1 will help Organic and Paid Search results.
+1 Analytics are coming:
The +1 will be integrated into analytics within hours of adding it to your site.
NOTE: Coming soon –Other Social Network buttons (Facebook, Twitter and Delicious logos were shown on this slide) will also be integrated into Analytics (Not previously announced).
The +1 uses the canonical tag to determine what you are +1ing on similar pages. Note: In the seminar they specifically said “similar” not “identical.
You can have multiple +1’s for different articles or sections on a single page by specifying the HREF (link) in the +1 code.
Do not buy +1’s or sell them.
However, they did say you can hide content behind a +1 button using drop-downs or collapsible div using the code to increase clicks. Idea: Exclusive videos or content for +1 clicks.
