I have been using Simple SEO for a year now. I have 80,000 products and 400 categories. I noticed that I am getting a lot of errors in my webmaster tool due to not found. I also notice in other search engines that the language prefix is added to the URL which cause duplicate in the URLs sent to search engine.

I am debating between dynamic and static urls. It seems that if you don't do the static URL correct the cons will out weight the pros.

I use SEO re-write on my Wordpress setup and I never run into problems with Google. If I submit 10 links in the sitemap I get 9 indexed but I submit 100,000 link in Zen Cart sitemap I would be lucky if 10,000 get indexed.

The question is how does this mod compare to Simple SEO as far as speed of rewriting. I have multiple level categories. Is it possible to configure this mod to only display the last category in the category Tree.

Conor, if you think we can assist me in figuring out how to actually benefit from static URL please IM me or email me so we can discuss that. I don't mind paying for your time.
