I am considering to change the link structure on one of my websites. The current links are The new link structure would be "category" represents the category name and "article-name" represents the actual name of the article (is also in H1 tags). I wrote an .htaccess rule to redirect from old to new. There are a few more rules, but that is not what the question is really about. 1) Is the rule itself sufficient enough or does it need to be a 301 and how would the rule then look like? 2) What's the impact for my rankings and page rank that I would have to expect? Is it better to forget the entire idea and stay where I am? The site is a few years old and uses a commercial (now by development abandonded) software. I'd hate to put my rankings at risk just by trying to SEO the site a little better. Any feedback would be welcome. Thanks. Christoph
