I am redesigning a gallery which has several different pages and want to make it just one page. I would take the content from each existing page and add it to this one page. I would use 301 re-directs to direct traffic from the old pages to the one page. Would this hurt the keyword rankings for the pages I will be redirecting at all? I have read initially traffic will change, bit then it should be back to normal after a few weeks once everything is indexed. My client needs some reassurance his current traffic won't be affected.
