I would like a little input on what to do about sites linking to me after the penguin update. I just checked the backlinks in WMT for a couple of my sites and I am not sure what to make of it. For instance, I have a gardening site and the top site that is linking back to me has given me 663 links on 22 of my pages. I have never heard of this site. It is in the same niche, but it is just a sales page for a Clickbank product. I have no idea where the links are located, but it seems to me they are trying to hurt my site - what do you think?
Also, I subscribe to the ABC backlink network and I think after Penguin it might be hurting to have all these links coming from sites that are not even remotely related to my niche. Thinking about stopping my subscription. But then what to do about backlinks? I am 'content' oriented marketer. I like to add fresh content to my sites, and I find that is where I focus my efforts. I will write articles for backlinks, but that is about it.
Input would be appreciated!
