Started a site on 12/1 Google has visited often, I have an "article" page that is linked off the home page, in the sitemap, easily accessable and has been crawled and indexed successfully. Back around 12/10 when it crawled the page for the first time there were 3 nice articles there and when I check the cached data from that site it shows the 3 articles. Here we are over a month later (and many more articles) and it hasn't indexed the page ever again and this is where all the "meat" of the site is. Webmaster tools and other Google tools show zero problems, any suggestions? Or do I just wait?
Just wait and build links to these pages. Google spiders will find your deep links from links on other websites. Concentrate on increasing your PR, Google will crawl your site more often and also spider deep links more often.
Don't just wait, help index and crawl your site. Use social bookmarking, forums sigs, article submissions and many other methods to let google bots visit your site.
It's the best advice, keep on doing that.. obtaining more backlinks specially deep links to the main pages if possible
