Buying Backlinks

Ok whats the main things to look for when buying backlinks, and should you also change the anchor text once in while.

My best tip:
- Make sure the backlinks are not coming from pages with huge amounts of outbound links

When buying links first and foremost you need to make sure that you do not buy them from a site that is advertising that they are selling links (link brokers such as linkworth.com are ok), then you want to make sure that you get your links that are embedded within the content from a RELEVANT site I can never stress this enough, you should definitely change the anchor text and try to use LSI words as well as on the anchor text and on the actual page that is giving you the link, that fact alone will help a lot, ideally if possible you should have the keywords in the title of the page where you are buying your links from.
