Will adding affiliate links negatively affect my SEO?

[SamCUK]

I'm thinking of signing up to a couple of affiliate programs related to my industry. Will adding affiliate links at the bottom of articles for example negatively affect my seo? I intend to have lots of useful content on my site and not just affililate links.

Samuel,

I don't think there will be a negative effect unless there is an abundance of these and the page becomes spammy. A couple of cautions would be: "at the bottom of articles" links lower in a page have less value, links in the footer are IMHO of little or no value and tend to clutter everything.

Your site has a nice clean look right now and you dont want tons of links all over the place. If you keep quality content and diverse links you should be fine.
