Ok well I have a few noob SEO Questions: What is the difference between hardlinks and backlinks? If I buy backlinks, do they have to be of my niche? (Like for example I have a website about porn, do I need backlinks from other porn sites?) If I want to increase the PR of my porn website, will buying .edu links help me? Thank you.
I dont think hardlink is associated to seo. nyways backlink is a link that links some other site to yours through some anchor text. and it is better that u get backlinks from your own niche and the anchortext should contain atleast a few keywords.
Not sure what you mean by a hardlink, I've never heard of this before. Its better if you backlinks have come from a relevant site, and it goes without saying that you anchor text should be keyword rich.
I do not know about hardlinks. Back links are made through hyperlinks or in simple words just a link that lies behind a text. That text is anchor text and it must be somewhere near your targeted keyword. I wonder .edu sites will offer back links to a port site. Anyway, for a porn site try to get back links from porn sites. It will help. Since porn is slightly different from other niches you will hardly find blogs offering you back links with porn related anchor text.
Hardlinks don't have anything to do with backlinks. If you buy links you should learn about the structure of linking first. How links work, what to link to, different types of links etc..
