Subpages not crawled

Subpages not crawled by Google, MSN

Hi,

All the major search engines have crawled my website by only the entry pages are scanned. I have over 20,000 pages which are not being referred to.

Any inputs on this please?
Enclosed robots.txt which disallows only /bin folder

How long has the site been up? It can take some time for sites to show up in the indexes.

Hi,

The site is up for 6 months, and google, yahoo, msn have been crawling on a fortnight/monthly basis, i could see the log and email analysis.

however, subpages are not indexed only root pages!
