Hi, I have read numerous articles that support submitting multiple XML sitemaps for websites that have thousands of articles... in our case we have over 100,000.  So, I was thinking I should submit one sitemap for each news category. My question is how many page levels should each sitemap instruct the spiders to go?  Would it not be enough to just submit the top level URL for each category and then let the spiders follow the rest of the links organically? So, if I have 12 categories the total number of URL´s will be 12??? If this is true, how do you suggest handling or home page, where the latest articles are displayed regardless of their category... so I.E. the spiders will find l links to a given article both on the home page and in the category it belongs to.  We are using canonical tags. Thanks, Jarrett
