Hey Guys, I just picked up a new client for SEO and Web Design for eCommerce sites.. They own a bunch of domains with good age and already good meta tags, etc. Their design looks horrific and they want everything from web design completely revamped and adding in new products.. I feel more comfortable working on Wordpress with this so i can install some good seo plugins. If i were to transfer the coding to Word press would this affect my rankings with google in a negative way?
