Only buy links from sites that are highly relevant to your web site content
If the site you are buying links from already has more than 5 paid links on the page, walk away
If the site labels the links as “sponsored” or “paid links” or anything like that, walk away
Don’t buy footer or sidebar links
Check that the page ranks well for its targeted keywords
Try to make your anchor text look natural
Point the links at different pages within your site. Don’t buy lots of links for your homepage
and do not buy
links on irrelevant sites
all your links from .edu sites
all your links from .gov sites
links from large networks all sitting on the same C Block IP
Purchase links around stop words such as advertisement, paid, partners
all your links from forum signatures

Some great tips! If I am going to pay for a link, I want it to be the absolute best for my site.
Good information and I think you should make another post about the recent things google has done to penalize those who “buy links.” It’s still a much needed thing in today’s world. However, it’s getting harder and harder to do it and not get penalized.
