Should the sitemap include just menu pages or all pages site wide?

[EricPacifico]

I have a Drupal site that utilizes Solr, with 10 menu pages and about 4,000 pages of content. Redoing a few things and we'll need to revamp the sitemap. Typically I'd jam all pages into a single sitemap and that's it, but post-Panda, should I do anything different?

Every page of your site that you wish to be indexed should be included in the sitemap you submit to search engines.

If there are pages on your site that are questionable due to duplicate content or thin content issues, those pages should either be removed or have the noindex meta tag added, then excluded from the sitemap.

Maybe even a robots.txt for a particular page like "advanced catalog" for ecommerce sites.
