De-indexed keyword on serps

Hard as it is, don't sweat these things until it extends for several days or even a couple weeks. Google "dances" like a medieval peasant who ate some bad rye bread (St. Vitus) all the time. Stability in the SERPs there is the exception to the rule, I'd argue.

If your blog is new and it was only at #200 or so, chances are what you were seeing that got you to #200 was what they call QDF (Query Deserves Freshness). This is part of the Google algorithm that gives a temporary boost to fresh content that Google discovers, regardless of its source. This is theory, by the way, but it's pretty well documented to be a real phenomenon. Anyway, that's probably why your site was at #200. Now it has disappeared because it's where it really belongs (for now). Keep working on building links and use good anchor text. You'll climb up over the coming months. It's tough with new sites, especially if you're in a tough niche to crack. Persistence and an eye on the long-term success is the key to staying motivated. Never stop getting links and add fresh content now and then to keep the Google spiders happy and well fed.

Thanks for the Tip John, I am fairly new to internet market, but I guess is better to experience Google moods at this point than down the road when I start to make some money, This just tells me that Adsense is great, but I should start diversifying now rather than later.
