I am on #492 on yahoo for "free php scripts" and on #200 for "free php script" ... the thing it's that i didn't optimizated it for a while, this week i would like to post my new websites + get around 200 backlinks... my problem : google dropped me for it's search results! Google bot it's coming daily to my websits, or even 3-4 times a day, trying to find lot's of intersteing pages like [login to view URL] [login to view URL] [login to view URL] but .... doing nothing... I would like somebody to help me to put [login to view URL] back on google, or/and explain me what i did wrong... and what should I do ... google never liked this domain name, it took 7 months to put in serps, and it have been dropped 3 days ago. Maiby somebody from IP class did some spam ... or maiby I duno ... this domain name was 1 year ago owned by somebody else. Also if I will get back to serps, will I suffer again the 'sandbox' effect?!
