We are trying to improve our website www.thekennelco.co.uk and have looked at the Google Page Speed and get the errors below which need resolved. From what I can see, these are related to files which we cannot control - I am not sure if we have access to the vendors.js?
Anyway, does anyone have any tips on how we can improve these metrics?
I have checked your store in page speed insight tool, yeah Its very low and low mobile page speed may kill your traffic and affect your conversion.
We cannot remove vendor.js as it require for shopify store.
Or defer them one by one and check if it messes with anything in your store. after adding defer, preview your store and see if everything works – things like your add to cart and popups.
You're loading the script for Google Tag manager 3 times, these are probably from third party monitoring services, I suggest you organize all your analytics and reduce all your tags into a single Tag manager container and only load one instance of the google tag manager script.
