There's a few really good SEO blogs out there. Unfortunately, the best ones rarely get updated. bluehatseo.com is one. Another is makemoneyonlinewithseo.com. So makemoneyonlinewithseo.com just came out with a new post about bringing a deindexed website back from the dead. The particular site he's doing in his case study right now got around 2500 uniques a day and profited around $300 per month. It was completely deindexed. I'll paste a few points just to give you a taste of what the post is about ... There's a lot more to the post. I recommend checking the site out, the guy knows what he is talking about and has chronicled many of his experiences with adsense and microniche websites. Check out the post here.
