This past weekend I pulled out the winter squash, the last of my summer plants.
It was still growing slowly as the temperatures haven't dropped low enough yet, but it was growing v e r y slowly and I needed that space to plant the next plants (fava beans).
That let us lock-in our harvest (130 pounds of squash), get the beans planted, and we only lost out on a couple more weeks of growth. It would have been optimal for the squash's growth to wait until the very end but then the fava beans wouldn't have had as much time to grow before winter. What was optimal for the squash, was sub-optimal for the garden as a whole.
As you work on and optimize your Shopify store you'll come across things that are doing well, but not yet maximized. You could improve them to their max, but that'll take resources away from something else that could have a larger impact on your main metrics.
You should note down any ideas but leave them for later. That's why I like to come back regularly and review the list of optimization ideas I have. What wasn't worthwhile last year might be worth it now.
You'll have a hard time finding optimizations for your customer loyalty and repeat orders unless you use something like Repeat Customer Insights to crunch your data. Those optimizations are usually hidden in the data away from where CRO experts usually look.
