Google has let webmasters and developers verify ownership of their sites in Webmaster Tools for some time, but now Google has also added the option from the Chrome Web Store, which makes a great deal of sense, considering that to publish an app in the store, developers have to prove that they own the domain that hosts it.
"Suppose you want to publish an app on the Chrome Web Store and have it associated with your company’s existing site, but you don’t have the ability to use any of the current verification methods e.g. you’re not allowed to upload a verification file to the root directory," says Google developer advocate Joe Marini. "The site verification service option in the edit page for each item listed in your Chrome Web Store developer dashboard allows you to request association of your app with your organization’s site."
"When you choose an existing site from the drop-down menu or click 'Add a new site', the current registered owner for the site will receive a notification of your request to be associated," adds Marini. "The owner can see who is making the request, and then approve or deny the request appropriately. That’s all there is to it! (Note: if this checkbox isn’t available, it may be because there’s no current owner of the site or you already have an outstanding association request)."
The addition of this feature seems like a no-brainer, but either way, it's here now.
