that’s assuming your target client has no idea that page size has anything to do with speed
This is not the case all the time. It’s the technique we employ to make this happen. Weight in KBs doesn’t necessarily equate to slow site.
Clients are somewhat familiar with popular tools out there. So using the same services makes sense for me. Here’s a site I’m optimizing collegiatepress.com, here’s dev version collegiatepressdev.neu.edu there’s nothing more powerful that showing the client all A’s. That’s one thing they can understand. :D
