Welcome to the Q&A Forum

Hi all, We are going to launch a new site design for our current e-commerce site. I have taken this opportunity to change some categories due to keyword research and all old categories will be 301ed to best fitting new category. So I have 2 questions about moving stuff over; 1. I read that leaving the old xml site map running for the first week, would help, because this would give crawlers the chance to run through the site and follow the 301s, which would help pass the juice. How true does this sound? 2. I was thinking of re-writing all category and sub category titles, meta descriptions and on page content. The positive of this is loads of fresh content - but doing this all at the same time with the new site launch might see some major dropping in search ranking. I've identified our top traffic keyword terms/pages, would it be more wise to leave these pages, and change the others, or would the total new fresh burst have a better impact? Cheers
