I bought two domains from Go daddy on 30th of June 2011 http://www.recruitment2012.info and http://www.results2012.info After that i started posting genuine posts on these two blogs.My first blog (http://www.recruitment2012.info) got to number one position in Google for Keyword "IBPS Recruitment 2011" and it remained there for 3 days ie 15th,16th and 17th July 2011.Due to such ranking i got 5400 unique visitors on 17th July.But when i checked for this keyword on 18 th July,my page was slipped to #68 th position on Google.then i check for the other keywords.for every single keyword my website was on 6th or 7th page This thing has happened with me a couple of times ago.Someone said that Google has put your site in sandbox.Other says that your domain name is highly competitive so u need time to get back to number one page on Google But Frankly speaking i don't find the technical answer to this question.If someone there who known the technical answer for this problem then plz help me out of this Thanks and regards
i think the problem is your domain name. have you checked which site has got your previous position? then try to study their process of SEO. you will find your drawbacks. and of you see and think that your page is in the better position of SEO than the others then of course your site is in the sand box.
Someone told me that my domain name is highly competitive so may be Google thinks that my domain age is not that much to complete for that keyword
This also happens when some one buys the 1st position from GOOGLE. google puts it on the first rank for couple of days according to the contract and then puts it farther then they put you. It is paid ranking or contract based ranking. Now the only way out is haaaaard struggle. You have to start SEO process and bring it to peak again. Wish u all the best. OMER FAROOQ
