Google: +1 Button Served 5 Billion Times A Day

Google Says 1/3 Of Search Ads Are Now ‘Enhanced’, Launches New Formats

As I reported earlier today, Google is launching a marketing campaign to tout and promote the use of enhanced search ads, which it says are now shown for roughly one-third of all search ads.

I lifted some of the numbers that they’re boasting about on the dedicated marketing website, but I thought it’d be worth doing a separate post on the numbers they shared in relation to the +1 button, which the company started rolling out at the end of March 2011 (and more broadly last June).

Says Nick Fox, VP of Product Management at Google, in the blog post:

Since introducing the +1 button earlier this year, we now have more than 5 billion impressions on publisher sites a day.

And on the enhanced search ads marketing website, the company claims:

Our +1 button is being served 2.3 billion times a day all over the web.

I’m not sure where the discrepancy between those numbers stems from – both numbers were released today – but it’s always possible one statistic is older than the other. It’s also possible Google simply didn’t do a stellar job explaining, or that ‘serving’ and ‘impressions’ are not the same thing in their book. One theory is that the +1 button gets served 5 billion times a day on publisher sites, and clicked 2.3 billion times across the Web (including in Google search results).

We’ve asked Google for clarification, but either way, the +1 button looks like something of a hit.

UPDATE: According to Google, the +1 button is now being served 5 billion times per day; the 2.5 billion stat was from the company’s Q2 earnings call in July.
