Thanks for reaching out. I'd be happy to look into this for you. First, I'd like to clarify a couple things:
1. Are you referring to the online speed score feature built in Shopify? If so, what was the score?
2. Are all areas of your website loading slowly or a particular one (Homepage, collections, products, etc.)?
3. What is the name of the theme you are currently using?
In the meantime, I recommend going through our guide on improving your online store speed to get the most out of your website. There are several actionable steps that you can take in that guide to improve your speed.
If there is anything else I can help you with, please let me know.
I see! I would recommend using Shopify's online store speed report as well to get accurate page speed insights. With that said, I'd be happy to offer some tips on how you can optimize your website for page speed.
Many of these changes relate to the quality of your Shopify theme, so it is important to choose a well-built theme (whether it is custom or purchased from our theme store) that follows our theme best practices
Oversized images take longer to load, so it’s important that you keep your images as small as possible. Be sure to crop your images to the correct size. For instance, if the space for an image is 300px wide, resize the image to that width.
Reduce the number of apps, plug-ins, and scripts
These slow your site, create a larger security footprint, and often cause crashes and other technical difficulties. Deactivate, delete, or remove any unnecessary apps, plug-ins or tracking scripts. Try selectively uninstalling problem apps, then measuring page load time. This way you can identify any that harm your site speed.
I hope this helps! If there is anything else I can help you with, please let me know.
