The Google Robot Don't Went Deep

I would like to know how I can make the robot go deeper in my website. For example I've made a change to the website title and description and I waited for the robot to come. He came made the changes to the title and description, but he didn't go deeper in my website to reindex the pages on that I've also made changes. I have link to those pages like this ..

Index -> Articles -> article1 , article 2, article3

article1 , article 2, article3 - are the pages where I've made the changes.

Thanks

 

I'm no expert but I believe a sitemap will help this. A link from the index page to a sitemap.

 

I already have a sitemap for that website submitted at Google Webmaster Central. Should I resubmit a new one ?

 

TRy with site map.You can create free and easy through www.auditmypc.com

 

Also place the link of your article 1. artricle2, article 3 pages on the main article page and also made sitemap and categoprised it and also create a XML sitemap on Google so that your deeper pages will be indexed ....

 

Crawl rate & depth is dependent on the PR of your site. You need to get more trusted, natural links with a high PR to get deeper crawling.
