Can I use ultimate seo urls and Ceon URI Mapping together? They both have something I want. Ceon URI Mapping is difficult to use when I want to rewrite other pages like reviews contact us and news articles. That is easy for ultimate seo urls. But the problem of ultimate seo urls is that there's always a number in the url and they can not rewrite categories url as xx.com/xx/. It will be xx.com/xxx-1.html. That's not perfect for seoer. SO I'm here to ask for help that if I can use them together. Will there be any conflict or I should try it myelf first?
