Helloo, one of my blogger blogs have been blocked in google searches, l was fething news from some populer sites for this blog, l also hosted a domain for this blogger blog , it was having around 500 daily hits at first months but than suddenly traffic gone and l realised google blocked it. than l removed the hosted domain from blogger and it became xxx.blogspot.com now, but l am not hopefull google will going to index this new subdomain and will giwe same traffic again. l want to know some informations about you, what do u think? Google will unblock site? May giwe same traffic? pls write ur reviews...
duplicate content pages are always facing such glitches of quick indexing and sudden de-indexing followed by it...so i dnt think that penalty will removed unless u seriously think bout ur content irrespective of diff sub domains.
Yeah, you should probably change most of the content you already have on your website if you want your page back in the rankings.
