Source: Ask Yoast: can backlinks from one site hurt my rankings?
Backlinks to your website usually contribute to your rankings. So generally you’d be happy to get lots links to your posts and pages. But what if you get lots of links from one site? Would Google consider that as suspicious, and could you therefore be penalized?
In this Ask Yoast we’ll take a question from Gabriel Heffes of Alberta Home Services:
“I recently had a post on Tumblr that was reblogged and resulted in 9000 links to my page, making Tumblr and that post the most link sending post. Will these thousands of links cause a Penguin penalty and hurt my rankings?”
In the video below we’ll explain whether all those links could result in a penalty or not!
Are backlinks from Tumblr dangerous?
“The honest answer is: no. This is actually a good thing, not a bad thing. Google knows how Tumblr works. It can see that these links are not bought or in any other way bad. So don’t worry about them. Celebrate the fact that you’ve got so many links on Tumblr! And make sure you’ll create another post like this, because it will actually help in your ranking. Good luck!”
