Google announced a new link building tool for Affiliate Network publishers by way of Chrome extension. It's called, simply, the Google Affiliate Network Link Building.
"Publishers have long been able to create links by signing into Google Affiliate Network and creating a Publisher-specific link (PSL)," explains engineering manager Ben Collins-Sussman. "Now, the Google Affiliate Network Link Builder enables publishers to create affiliate ads that link directly to unique product pages -- right from an advertiser’s website."
"If a great product catches your eye while browsing, why shouldn't a PSL be anything more than a click away?" he adds. "With our new Chrome extension, it isn’t. The extension displays a button in the corner of your browser window. If the advertiser's program supports deep linking, you can easily create a PSL for any product you’re viewing by clicking the button."
The tool makes calls to the Google Affiliate Network public API. You have to be signed into Chrome with your publisher account. The extension downloads your advertiser relationships, and then recognizes when you have an affiliate relationship with a site you're on.
