In February this year I registered mysite.com and started building, I did a lot of research on both on- and offline SEO techniques. I have a google sitemap, googlebot is camping on mysite.com, whenever I check my stats the bot is there or has just left, I get some traffic every day through google so all goes well.
Mysite.com is going fine so a few months back I also registered mysite.org because I needed another url to test some stuff before I apply it to mysite.com so I opened a subdomain on mysite.org named xxx.mysite.org I have a robots.txt there telling all the bots not to index anything on xxx.mysite.org.Not a single link is going to mysite.org and the PR is 0. On the index page of mysite.org there is only a message of the hosting company so nothing at all.
All my SEO efforts paid off and for my main keyword mysite.com gets first position on yahoo. Untill recent I got spot 3 to 7 on google for mysite.com the spots above me are from sites with high pagerank that I have placed a link on or that mention my site, so it's logical that those heavy weight sites with PR7 or 8 outrank my new site for my main keyword, this is something that will change overtime.
Now it's get weird, last week mysite.com suddenly dropped from position 4 to position 97, so mysite.com landed on page 9 of the serp results. I didn't do anything but a day later it was back there at spot 4 but now for the last 5 days it keeps at spot 97 in google's serp results.
Now get this, yesterday I checked again and what do I see? Mysite.org with PR0 and no content has spot 1 for the mysite keyword in google. Nothing links to it, no seo no nothing
and I checked a few times today and there it is still on spot 1.
I do know google found out about mysite.org pretty soon after I registered it but I haven't got a clue what is going on. I tried so hard to understand google but I don't get the hang of it, I don't do blackhat stuff or anything I understand yahoo, google must like mysite.com because it has indexed around 1400 pages so far but those serp positions are rediculous.
So what do you think?
