If you have been one of Google’s 33 million unique visitors today*, then you must have noticed the best ad placement ever: meet Google ad for Google Plus (with a nice blue arrow!).
Even if you haven't joined the new social network yet, you should see a +You instead of your name. Smart!
Google has used this clever “ad-placement” before, when it advertised for its own browser Google Chrome, for HTC Magic in 2010 or for Google Offers in 2011.
Now that Google Plus is open to the public, I wonder how many people will join. I guess we’ll find out soon!
Have you joined Google+ yet?
* According to comCore, Google has 1 billion unique visitors a month
