Welcome to the Q&A Forum

A site I'm involved with, www.organicguide.com, was at one stage (long ago) performing reasonably well in the search engines. It was ranking highly for several keywords. The site has been neglected for some considerable period of time. A new group of people are interested in revamping the site, updating content, removing some of the existing content, and generally refreshing the site entirely. In order to go forward with the site, significant changes need to be made. This will likely involve moving the entire site across to wordpress. The directory software (edirectory.com) currently being used has not been designed with SEO in mind and as a result numerous similar pages of directory listings (all with similar titles and descriptions) are in google's results, albeit with very weak PA. After reading many of the articles/blog posts here I realize that a significant revamp and some serious SEO work is needed. So, I've joined this community to learn from those more experienced. Apart from doing 301 redirects for pages that we need to retain, is there any optimal way of removing/repairing the current URL structure as the site gets updated? Also, is it better to make changes all at once or is an iterative approach preferred? Many thanks in advance for any responses/advice offered. Cheers MacRobbo
