I understand the importance of properly attributing an image / original work, but I noticed this on Yelp’s Display Requirements page:
Originally I was scanning through Yelp’s FAQ and noticed that part of their TOS forbids webmasters from using Yelp content without a link back.
There is no doubt about it that Yelp is a mega brand and gets thousands of legit links from many reputable sources.
The question remains: Is the fact that Yelp requires do-follow links a violation of Google Webmaster Guidelines, or is it fair to say that if you use Yelp’s content it is fair that they ask for a link?
I’ve spoken to several people about this example over the past few days, most of them agree that requiring webmasters to insert a do-follow link to your site can only mean one thing: you are in it for the PageRank.
In my opinion, it is one thing asking for attribution but requiring users to insert a do-follow link from their site / app /API
Google’s definition of a link scheme is laid out pretty clearly. Links should be placed organically and those that were not editorially placed or vouched for will most likely be in violation of Google’s Webmaster Guidelines.
I think it is very important to discuss these situations openly. It seems like these grey areas are coming up more and more often in the media so it is always good to get feedback from those that might have dealt with a similar situation.
