I’m trying to enable Google+ social extension – I added the <rel=publisher tag to the website within the head tag yesterday, and the Google + page links back to our main website. But it still says “Requires Google+ Page link”

Anybody know how long it typically takes before AdWords recognizes the link?

I’ve found it can take Google anywhere from a few days to at most a week to recognize the tags. I did have one implementation that just wasn’t taking and I had to have an AdWords rep sort it out on the backend. That only happened once though.
