14 DAY TRIAL // Google's introduction of the +1 button earlier today had one interesting side note, the button will also show up on ads in the search results page. This means that users will be able to +1 'like' ads just like they do regular links.
Of course, since it's rather unlikely that users will do this too often, the ads will also indicate how many times people have 'liked' the particular link in a regular search result or on the page itself once the embeddable buttons show up.
"We expect that personalized annotations will help users know when your ads and organic search results are relevant to them, increasing the chances that they'll end up on your site," Google's Dan Friedman writes.
"You don’t have to make adjustments to your advertising strategy based on +1 buttons, and the way we calculate Quality Score isn’t changing (though +1s will be one of many signals we use to calculate organic search ranking). Think of +1 buttons as an enhancement that can help already successful search campaigns perform even better," he explains.
The +1 button is rolling out gradually. But those that can already see it, or opt into the experimental program, will notice that ads sport it as well as regular results.
If you think a particular ad could be useful to your friends or contacts, there's no easier way of telling them. Alternatively, if an advertiser uses the same URL in an ad that users have 'liked' in the organic results, this will count towards the +1 number, since the infrastructure and data is common between them.
Advertisers can opt out of the program altogether if they don't like the idea. And Google assures them that they are not billed if a user clicks on the +1 button and not on the link. In theory, advertisers have very little to lose which is why Google hopes many of them will adopt +1, especially when the website version comes out.
