Hi guys I'm working for a company, just doing general site updates as well as graphic design for them and I told the owner about Wordpress. He's been working solid on his HTML and PHP based sites for a couple of years now (going very whitehat, 'slowly wins the race') for a local and national service, and the sites are doing ok, getting position 20+ for a lot of his keywords, but he's concerned that Wordpress will throw it all out of proportion and all the link building, on-site SEO etc. will go out of the window. So I just wanted to ask some of you for some advice on changing a fairly regular site to a Wordpress based site and how it affected your rankings, what changed and how drastic it all was. And also for any tips that people who have done this before may have. Thanks always given to helpful responses and rep given as always if deserved Cheers guys.
