Welcome to the Q&A Forum

We have looked into doing this, but we was just spammed by Tumblr links which ended up dropping us in the rankings for some keywords.

Thanks for the reply.

Hi, I'm new to link building. I have done some research of my competitors and have found that many of them are being linked to sites like this http://www.worldofwondersvu.com/

As you can see, this website looks like a business website, but if you view the content, it's spammed with external links.

I'm just wondering what method they are going about to get these links, because most of the websites that are linking to them are simular to the one I posted above!

Thanks
