I was checking out this article which contained a video interview with Matt Cutt’s. In the video (worth watching) they talk about site speed becoming a ranking factor in 2010. Matt mentions a page called code.google.com/speed. This is pretty much a big resource for making your site faster for Google. The firefox page speed add on is pretty helpful in determining how fast or slow your pages are loading. It’s worth a shot to download it and check your sites, one thing I noticed I wasn’t doing was browser side caching. It pretty much allows a visitor’s browser to cache all the images on your site until their set expiration date. This cuts down your bandwidth and also doesn’t make the user reload every image for every page view, thus drastically increasing the page load speed.
I have found that almost none of the affiliate sites I checked are leveraging browser caching, and many of them have a slew of other factors slowing down their pages. Anything from not using gzip compression to unused css to bulky javascript to not specifying image sizes etc etc the list goes on. Chances are your pages don’t have any drastic mistakes slowing them down, but a bunch of small factors can have a big impact. My pages on my online poker site are ripping fast, are yours?
