what is the best structure for seo without have problems on future?

the best urls schemas in PrestaShop are:

1. Route to product: {category:/}{rewrite}.html optionally {category:/}{rewrite}
2. Route to category: {category:/}{rewrite}/ or {category:/}{rewrite}
3. Route to supplier: supplier/{rewrite}/ or supplier/{rewrite} (you can replace word 'supplier' with similar / equal word in other languages)
4. Route to manufacturer: manufacturer/{rewrite}/ or manufacturer/{rewrite} (you can replace word 'manufacturer' with similar / equal word in other languages)
5. Route to CMS page: info/{rewrite}.html or info/{rewrite}
6. Route to CMS category page info/{rewrite}

to remove the ID you can use module "pretty clean urls"
