Slow websites cause irritation for users because they are on your site expecting to view the content their looking for quickly and with little downtime between pages. This is especially true for eCommerce sites which benefit from allowing their customers to jump from product to product on a whim and allow a smooth and pain free check out process.
I am a web developer with tools and the knowledge to test your webpage and provide a list of speed problems for you webpage.
Various fixes I look at include:
- Image Optmization - File compression - Reducing requests to the server - Reducing unneeded code - Browser Caching
