Requirements: Successful prior experience in minimizing site load time and site optimization. Experience with YSlow and Google PageSpeed. Great coding skills.
One of my sites is very slow to load. Google says: "On average, pages in your site take 5.2 seconds to load. This is slower than 76% of sites." YSlow gives it a grade of D.
I know for sure this is hurting greatly the search rankings for the site in Google as Google has stated that slowness is a big negative factor. The site is a Wordpress-based content site on Apache web server hosted on a VPS, and I just had the host install deflate module but I know that's not enough.
So your job would be to use tools like Google PageSpeed and YSlow to analyze and implement recommendations and speed up the site to a great loading time level. I would give you any access (FTP, etc) you need to do that.
