Most of what you need to avoid has been mentioned above. These days you need to have a fairly clean backlink profile. If you've got spammy links, you are being very risky. Try to make your links look as natural as possible. Use a wide variety of anchor text. Get links from many different sources. Ensure you don't have long stretches with no new links. Make sure your internal pages get links too. Also try to avoid getting links from bad neighborhoods or from pages that link to spammy sites. Having too many links from unrelated sites could be an issue too.
Don't use any kind of automated software, do it yourself. Don't build too much links in a day and target all your site pages.
