i found my site by domain name but when i go to check for its indexing i hardly found it there , how come this happen and is this mean that my site is banned by BIG BOSS
Probably your web site into the Google sand box, this requires a period of waiting for will come out,
How old is your site? New sites tend to go in and out of the SERPs and as long as you can still find your site on the SERPs, then you should be fine. Just continue building links to your site and it will soon get back into the SERPs. Hope that helps. Have a good day!
Yea, just fix the problem. If you duplicate the site on a new domain you will experience the same results.
yes it means that it was sandboxed as others suggested. I would recommend that you still continue to build out your pages and ping the pages to show to the search engines that it is relevant.
