I know some themes has this (https://instant.page) or very similar technologies built-in to improve perceived site speed.

Do you use it? How much of an improvement it is and are there any cons?

I’m also curious. I checked pages from the section “Trusted by” and I didn’t find this snippet in the source codes :thinking:

Why not properly optimize e-commerce, using Google guidelines? It’s not that hard to optimize Shopify stores, unlike WordPress.

Hi Tim!

There are two approaches you can use when it comes to prefetching future navigations:

  1. A JavaScript-based one, like the instant.page that you mentioned.
  2. A native one, based on the Speculation Rules API.

Both of them can be configured with different levels of aggressiveness when it comes to triggering potential future requests earlier. More eager approach will provide bigger improvements to the loading metrics, but may waste user data and lead to issues with outdated content on inaccurate analytics.

Personally, I would recommend waiting a week or two before implementing anything custom. We are working on a platform-wide solution that should provide a nice improvement without the downsides that I mentioned.
