Google to launch +1 for sites tomorrow

Google has dialed up the love you can show Web sites, reportedly adding its nascent +1 button to the arsenal Web developers can deploy.

The +1 button (pronounced "plus one") is Google's answer to Facebook's prolific "Like" feature, where users can click on an icon to show appreciation for a site.

In March, Google launched +1 as a way to let Web surfers like search results. That feature lets users who are logged in to their Google accounts keep tabs on their favorite search discoveries on Google, as well as giving the company tools to customize what sorts of ads it delivers. And the company uses the data from +1 to gauge the quality of its search results. The new +1 feature, first reported by TechCrunch and confirmed by Search Engine Land, will give sites the ability to add the +1 icon to their pages.




What's unclear is how those clicks will show up for others. When a Facebook user "likes" a Web page, it can be seen by all their friends on Facebook, and now on some search queries in Microsoft's Bing. But Google has no similar social network, so it remains to be seen how a person's clicking +1 will show up to other users.
