What would your personal experience - opinion on this matter?
1. getting rid of .html (sure I think if content is poor it wont benefit, but if there were too identical contents would you think bot would prefer shorter url ?
2. currently my categories are /category/subcategory/
white products
domain.com/product1
domain.com/product2
and so on, long time ago decided I want my urls to be as short as possible, but I cannot say I have strong, meaning good rank product pages or category pages, some of my blog pages and index page is rankest best.
Just if you can say yes no to the above it would be great. Thanks
First of all, let me know which CMS are you using on your site? And did you try to change permalink? It's called permalink that you can find in your CMS's settings.
