No.4 - Speed up your site
Depending on what platform you use, there will likely be limitations to what can be achieved here. If you use a hosted solution like Shopify, there’s no way to upgrade servers, but you shouldn’t need to as they are fast enough. If you use a non-hosted solution like Magento, make sure that you pay the server the attention it deserves. A slow site (e-Commerce or not) will never perform as well. Bounce rates increase exponentially as load time goes up. If your home page take more than 3 seconds, make some adjustments.
Beyond servers, the simplest way to make sure you site is as fast as possible is to ensure that images are properly optimised for the web. There’s a balance to be found here, you want product imagery to be sharp and have zoom functionality, but hero images, banner and collection imagery on the homepage should be as small in file as possible. Start by exporting images from photoshop and playing with the quality settings to reduce file size.
We also often use a free online service called Tiny PNG. It couldn’t be simpler to use, and the amount of compression is displayed so that you can clearly see how much you’re saving. Don’t be fooled by the aesthetic of the site itself, the algorithms used are intelligent and the results speak for themselves. Just make sure to compare the compressed images to the originals and make sure that the quality is up to scratch.
