A few years ago Amazon came out with their finding on how 1 addition second of website loading, could potentially cost them $1.6 billion.
Latency matters. Amazon found every 100ms of latency cost them 1% in sales. Google found an extra .5 seconds in search page generation time dropped traffic by 20%. A broker could lose $4 million in revenues per millisecond if their electronic trading platform is 5 milliseconds behind the competition.
Now I am not making millions, but it doesn’t hurt to improve user experience and increase my conversion rates. Here’s a simple little trick I pulled early this morning. By optimizing photos you can greatly reduce load time and overall size of the landing page without reducing the quality of the photos or user experience.
Here you see a before and after screenshot, and it took me just 10 minutes (I had to resize 3 photos I’ve uploaded neglecting to check file size which translated into 9 extra megabytes that didn’t have to load).
Naturally, I could shave another 500 milliseconds or maybe even a second in many other ways, but I am happy with 2.66 s for my personal blog. Naturally, this isn’t going to improve your product or bring you clients, but it will affect your conversion rates, and the overall feeling of browsing your website.
