I saw on Mr Affiliates post he mentioned to also use link exchange in addition to other backlink creating methods. My question is if two porn sites do a trade is it considered blackhat? For example if someone just dumps his porn links on a bunch of link dump sites but all of them are not porn related. But if people are on a porn site then link to another porn site does google see that as good sign?
Simply saying, you should always look for backlinks from porn websites in your own niche. If you have a blog about foot fetish then get some links from related sites. Google does not see it as a good sign when you get a bunch of backlinks from other porn sites that are completely unrelated to yours one.
