Are Google’s Social Reports Inaccurate?


In our latest observed case, Google+ reported only 25% of the +1′s on the page we monitored. 

Is this a bug?

Navigate to Traffic > +1 Reports > Activity > All +1′s and you will see something like this:

Social Data

We recently had a sudden surge of +1′s for that particular URL and expected a more dramatic jump in the cumulative +1 graph. Note that the total amount of +1′s for the highlighted URL is “25″ and now take a look at the actual number of +1′s from the page:

Plus Count

What is going on here? Why wouldn’t Google display the data it already has available for the URL correctly in Google Webmaster tools as well? Perhaps some of the +1′s attributed towards this URL come from Google+ shares, but we haven’t been able to confirm this.

Non-cumulative overview shows the activity but only 1/4 of what is displayed on the page’s +1 button:

Plus Activity

Search impact shows the recorded jump more clearly, as this time we’re not looking at cumulative data:

Search Impact

At the highest point the value is 35 followed by 30, 30 and 12 – in total: 107 for that period. Interestingly 106 is the total count on the +1 button on the page. This, however is just a coincidence.

Has anyone else observed any discrepancies between the social data reported in Google Webmaster Tools and what what is being reported by the social?
