I created 27 new sites for adsense .and created inbound link with each other.But I not find any backlinks for any sites by backlinkwatch.com iwebtool.com etc.why I not see backlinks?I will be grateful if anybody tell me how can I create backlink with my own sites.
Just because you don't see them using some backlinks tool doesn't mean they are not there. It takes time to get crawled and indexed. And Google does not report back all your links. Keep working and move on. Traffic is what matters. Traffic that converts.
What internet marketing says is true. It takes some time to get crawled. Backlinkwatch is using Yahoo to look for backlinks, so it might be possible that Yahoo didn't find your backlink yet. Maybe you should Ping your backlinks if you want them to get indexed faster.
