Is Google gone mad?? Rise And Fall in SERP
 

Hi there.
Here is my situation. Not so long ago, (4 months) i have started one blog with niche "teen", and after a couple of weeks it manage to climb up to PR2. Then i did another blog with different niche and on the daily bases he gets up to 15-20 visitors raising. And then i did 3. blog also targeted niche "teen". The third blog ( 3 months old) get up to 80 visitors and slowly raising. I did the best SEO i now, but suddenly the first two blogs simply disappeared from SERP. I am fighting now to get those two blogs on SERP-S, but no luck at all. Not to mention that there is no sales so far. The myth says that after 6 months living in send box you will rise up again. I am not. Some suggestions?

Tnx in advance.

It can be a MayDay collateral damage.
Keep on doing your SEO, do some deep-linking, add new content, and don't focus too much on it.
Before going to the sand box for six months or so, you always have a few weeks/months with good results. Paulo Coelho would call it the Beginner's Luck, then the Conquistador's Challenge.
Everything does not pay in the short-term, your only goal is the long haul in that business.
Keep on doing what you do, create networks, widen your niches, and soon enough, you won't pay too much attention anymore to the serps and rankings fluctuations.

sucks man but it's normal. Keep up the good work and be patient.

they did just implement some changes, not sure if this could be the cause as google is always changing shit... http://techcrunch.com/2010/06/08/google-caffeine/

Sometimes they did come back
 

Wtf, some of us will go to the hell anyway.
However, i did a little prayer ( i am not a believer), but did some changes on my site. A big one, replace template and remove spamy links. Then i rearrange my categories, and finally did one prayer. And the devil has shown himself. From non (O) i squeeze UP total 30 unique visitors from "G". Not bad? Considering that the only (3.) visitors from google were me, myself and i. I might did the right stuff or it was just coincidence. Recently i add a dozen hard links, one or two daily, but i don't think that this was the main reason why google send me (finally) 30. visitors? The war is still going on. I wonder, what is next prayer i should do??
I am just trying to isolate the problem, and to learn to avoid it in wide circle next time.

Did you stop updating frequently?

How old are the domains? If they are new that tends to happen. Just keep pushing and they will come back to where they were and if you are lucky to better listings then they were.

Google Is Not So (b)Mad
 

I update my site more frequently now, maybe twice a day. Finally it moves up. Sites are 6 months old. This is the result of the one of them The other site one is probably dead. This is the 3. day of raising incoming from google. And it is raising. I think i might have a clue...
