Now onwards, landing page load time factor will be incorporated into keywords’ Quality Scores. Keywords with landing pages that load slowly may get lower Quality Scores and thus higher minimum bids. On the other hand, keywords with landing pages that load very quickly may get higher Quality Scores and lower minimum bids. Your Quality Score may change/increase gradually over a number of weeks after you improve your load time. Factors Contributing to a slow load time: Below are common causes of a slow load time. If you don’t directly upkeep your site, you might want to pass this information along to your webmaster. Multi-second Meta refreshes Redirects that use multi-second meta refreshes are a common culprit. If you have a redirect set to occur after several seconds, change it to zero seconds so that the redirect happens immediately. Slow redirects To check the speed of your redirects, copy and paste your destination URL into a web browser to see how long the browser spends on each redirect URL. You can get more precise values using a tool like Fiddler (English only). Multiple redirects Each redirect increases your landing page load time. If you have more than one redirect, consider eliminating unnecessary ones. Interstitial pages If you employ an interstitial page (where the user waits for a few seconds before being taken to the landing page), you should consider removing it. Slow server Your site may be hosted by a slow server. Use Google’s Webmaster Tools to see how long your site takes to fetch. If it’s slow, contact your web hosting provider. Large page size If your page’s HTML document is very large, try compressing it with gzip or DEFLATE. So reduce your page load time to reduce the advertising cost

Great tips, I wonder what percentage of the quality score it makes up. Im assuming not very much, but every bit counts. Good luck -Patz
