Last week I posted 10 articles(ezinearticles.com), these articles link to my website. All articles are already indexed in Google but I havn't seen any backlinks yet. So, what is the problem?
Make sure that you've used the keywords in your subject, this will index you really quickly at most of search engines.
I have used the keywords in my subject and my main keyword in link's anchor text. But when i check google - link:mysite it doesn't show me any links from my articles. May be i should wait more?
Backlinks are not frequently update. You might need to wait a couple of months to see the change in backlinks.
It's not about how many articles you write, it's about HOW you write them. This might help http://rapidshare.com/files/85285747/Clickbank-Case-Study.pdf.html
Google does not list every back link. They only list backlinks from reliabel sites. It also often takes a very long time for google to show the backlinks. You should try to use yahoo to check your backlinks. Another great way to see your back links as they come is do a search in google for links to your site from google blog search. These links are posted as they happen.
