If you get a new wave of unnatural link penalties via the Google Search Console for widget links, don’t be surprised. Because, Google gives a stern warning on Webmaster blog. Google says that the links within widgets can be against their webmaster’s guidelines. Googlers, Agnieszka Łata, Trust & Safety Search Team and Eric Kuan, Webmaster Relations Specialist wrote “we would like to reiterate our policy on the creation of keyword-rich, hidden or low-quality links embedded in widgets that are distributed across various sites.” Google shared “some widgets add links to a site that a webmaster did not editorially place and contain anchor text that the webmaster does not control.” Google explained “because these links are not naturally placed, they’re considered a violation of Google Webmaster Guidelines.”
Google is requesting widget makers to remove the unnatural links from their widgets. If they don’t Google web-spam team may take manual action on that unnatural link. Google said you need to remove the links or add the rel=”nofollow” before submitting a reconsideration request.
Google said later on in their blog post. “Additionally, those that embed these widgets on their site should “add a rel=”nofollow” attribute on those unnatural links or remove the links entirely from the widget.”
