I have a site with PR1. I checked it at last 25th October night, it was in Google's 2nd page of few keywords (penis extender, enlarge penis, penis stretcher). But when i went to check it 26th October morning. It was not in Google's 2nd page not even in googles's ist 50 pages. I can't understand why. I am so panic-stricken. Can you guys help me to find out why.. My site is still Pr1. You can take a look my site at my signature...I didn't do anything spamming .....
i think its fluctuate result for your site, to make it consistant u need to build more back link for same keywords.
we as yet your ranking not stable in Google so ranking is up and down but don't worry for ranking ..only do regular work..after that it's will stable position..
no need to worry thats just what google does. nothing you can really do about it except focus on your content
