I'm looking for a service where I can specify a heck of a lot of keywords and a lot of urls. Then have links built almost randomly back to my main site to make it Penguin safe. It also would be best if the links were from a large variety of sources. This isn't to boost rankings, though it might. Instead it's for protecting rankings. As you probably know, having links back to your site where 60% or more use the same keyword is what seems to trigger Panda. Anyone know a service that will help do this?
