Hi, I just made a new version for my site. (it's not yet uploaded) I want to ask these : 1) Will this, affect google's page rank for my site ? Right now, I have pr:4, and the h1,h2,h3 tags will be different. Also, the pages titles, the metadescriptions and the main content (slightly) will be change. Will this affect my site's current position at search results? 2) Will i have to re-submit my new site to webmaster tools ?
