You just checked the PageSpeed score on your ecommerce site, and it's not great. Is this something to be concerned about? Probably not. Remember that a PageSpeed score is not actually speed. It's just a useful bit of guidance to help find some areas for improvement. On its own, it means very little. Ultimately, your site needs to be competitive and provide a good user experience. As long as you are on par with your competition, there's probably nothing to worry about. And for ecommerce sites, how much effort you should put in to outperforming your competition should probably be a financial decision, not a technical one.
