Welcome to the Q&A Forum

I got handed a website running on Joomla without the SEO friendly URL check box selected so our URLs all look like this www.rotaryvalve.com/index.php?option=com_content&view=article&id=22&Itemid=37 . I am hoping to rework this website in the near future here and plan on changing the URL structure across the website so there are some actual keywords in the URL. When I did this I was thinking of just doing 301 redirects to the new pages and hopefully the hit from the search engines wouldn't be too bad. Can anyone speak from experience as to what the best way to go about doing this would be so I don't end up falling back ranking wise. Would change the URLs end up helping me or hurting me? Thanks
