Page load time not only affects your quality score, but it can dramatically impact page load times. I recently worked with someone who’s landing pages were loading in about 15-20 seconds! That has a major affect on user experience. Very few people with broadband will wait even 5 seconds for a page to load, let alone 20 seconds. We reduced the size and number of images, decreased the amount of and size of includes and modified the hosting and caching settings of the web server. The result was a page that loaded in about two seconds. What an improvement! Think of all the people that were leaving even before they saw the message.
