My main money site is in need of a re-vamp. When I set it up, I used what I though was a good Wordpress theme, and a few different plugins. My theme is actually pretty shit, and has been having problems with various bits and pieces. (And I've had an e-mail from 1and1 saying that Wsijia Newsletter has a virus injected :-/). I basically want to start a new, clean WP install, and copy-paste my posts into the new site. I want to replace a few of the images, and edit a few of the posts (generally low word-count, non-ranking posts). I don't mind doing this the long way round, as I need to edit most posts to remove shortcodes for a plugin I made, and want to proof-read all the previous posts. Will this sort of redesign have a negative impact on my G rankings? I recently upgraded server speed, removed W3 cache, and installed a simpler minify plugin, and my rankings improved dramatically, so an even better (quicker) theme should in theory help even more. I'm going to be keeping the same URL structure, mostly the same images and post text, just a clean install with a clean theme (maybe change author name from my name, to the site's name). I presume it will cause a dance, but can I expect to come back with worse/better/same rankings? Cheers, BHF TL;DR version: Will a new WP install, new theme and minor changes have a negative impact on rankings?
