Welcome to the Q&A Forum

When you say 'submit all of your product pages' - Do you mean submit them to Google's organic search engine, or Google Shopping? For the organic search engine, depending on how many pages you really have, I would say you should submit xml sitemaps, and you may need to submit a sitemap index too (check the current max. limit on a single sitemap submission, I am not sure what it is these days!). Personally though, with a good navigation system and a few backlinks, you shouldn't need to worry 'too much' about submitting xml sitemaps. As you say the product pages are updated daily though, I can see why you feel the need to do this. Or, did you mean submitting them to... Google Shopping If you have lots of products, I would strongly recommend submitting them to Google Shopping - it's free, after all! This should help you to get some 'quick wins' whilst you work at getting your products and category pages ranking well in the organic results. **Canonicalisation ** As you are running an ecom. store, with lots of products - be very careful with canonical and duplication issues, especially since Google Panda! Ensure that query strings in your URLs don't result in multiple URLs for the same products, likewise make sure if you have products in multiple categories, that you are not creating duplicate content/URLs that way either! - I guess you have this covered already?
