Here’s a few post Penguin link building survival tips:
1. Don’t build terrible links towards your money site period! Stay away from comment spam, low grade directory links, Xrumer automated nonsense (a popular Negative SEO tool), sidebar links, footer links, mass article submissions, links on thin content sites, profile links, don’t buy a 1000 +1s and tweets from Fiver (this is really bad, you’ll burn your site very quickly, again a favoured Negative SEO tactic) and never buy links from TextLinks, a sure fire one way ticket to Google oblivion.
