Can anyone tell me why Google banned this site avnisays.com . 3 months before it has 3,000 pages in google but now Google has removed all pages. I had also re-submit it to Google but no result.
the referring site you mention was used for a week or two 9 months ago small amount of content until the domain name and separate website was established. The content has always been on one website although the videos are also on youtube.com
Strange - it´s showing 1064 indexed pages on Yahoo and 3 on Bing but nothing on Google. Is all the content original? Have you tried submitting it to Google again since the time you mentioned in your post?
There are many reasons why google ban the site. Its better to ask in webmaster forum in crawling and indexing category!!
I think you have used some black hat seo techniques, google normally bans such site's. Or you might have gone against their TOS.
I think that your content is not unique. If you search for "Making sure that you do not spend all of your money on power is a good way to make sure that your spending stays under control" (with quotes) and you can see that google returns a number of other sites with the same article.
