Came across this while surfing today. It’s a Google ad which the Skype for Firefox extension has added a click-to-call link to. First time I’ve seen this.
It seems the Skype Firefox extension (which scans web pages for phone numbers to highlight them in this way) can pick phone numbers out of Google’s javascript Adsense ads. This is different I feel from the ‘happy’ arrangement between Google and Skype’s parent eBay last year where they were working together to test click-to-call links.
With the recent suggestions of a cooling in relations between the two companies, it may just be that this is a shot across the bow from the eBay camp.
