I was recently checking my website for unnecessary 404s, 302s and 301s using ScreamingFrog spider and discovered hundreds of outgoing "dofollow" links to Disqus.com. All with the exact same anchor text:
Here's what's happened - Disqus' installation snippet comes with a link, that most people don't notice and/or forget to remove:
There's actually two "powered by" links, one inside the
<noscript> section, one outside. Those links have nothing to do with the functionality, removing them changes absolutely nothing.
On a side note, I personally believe there's nothing wrong with adding a "powered by" bottom link to your software, preferably, a "nofollowed" one (we were actually doing it ourselves in the past and got slapped by Google Penguin really hard but that's a different story). Also, Disqus makes a fine product and I don't mind linking to good stuff... But.
But the link is just one side of the coin.
The answer is simple: For Googlebot
This kinda looks like "cloaking" to me but let's just hope they made a mistake. Anyways, don't forget to remove that link when installing the code. Otherwise you're just another page linking to Disqus without even knowing it. Out of a whooping 240 MILLION PAGES:
