hi........shibi first of all you should have to send mail to google regarding information.... and you have to do concentrate on the quality work (like high pr all things)...
ok andyrodick...thanks you.. i have always concentarted in quality works.. i m doing..linkwheel,social bookmarking, article ,press relaese, blogs. forum posting etc... and the keywords for that page was first in google..but now it disappeard page and keyword also..
This is may be due to the penalize of your site from Google. Make sure whether is there any duplicate content in your website and take the relevant steps to overcome from it..
if your indexed, but not ranking, you need to do more seo (sandboxed or not). Also, I've heard google can spot link wheels and they don't take kindly to it
Do not ever send Google any info because they use machine not human in evaluating the site. Explain the thing you do in your site. How old is your site and are you doing link building or site update?
Dear, Have you check any note of penalization in search engine where you had the position? If there is no problem like that then you need to submit your website in webmaster of google, yahoo and bing. Also Update your website content and do article submission with unique content. You said that you are working on link wheel... Check the blogs that google considering those blogs which are in wheel or is they removed?
