Mimetic vs Google Lighthouse

A better score is not the same as more orders

Lighthouse is free, good at what it does, and you should run it. It grades a page. It does not walk your checkout, watch a real shopper fail to buy, or prepare the change that fixes it.

The gap

What Google Lighthouse misses.

Free automated auditing of performance, accessibility, best practices and basic SEO on a single page load

The buying journey, it grades one page rather than following a shopper from ad to order

Functional failures, a dead Add to Cart or a checkout that breaks on one browser will not lower your score

Tracking integrity, whether your pixels fire correctly and count once

Commercial priority, every issue is technical severity with no connection to orders

Implementation, it tells you what is slow, not what to change

In-app browsers, where a large share of paid social traffic actually lands

FAQ

Frequently asked questions.

Should I just use Lighthouse?

If you want to know whether a page is slow, yes, and it is free. Start there. Come back when the question is why shoppers are not buying, because a page can pass Lighthouse comfortably and still lose the sale at the cart.

Does Mimetic replace it?

No, and it does not try to. Performance is one input among several. Mimetic covers the buying journey and connects what it finds to orders, then prepares the change. Keep running Lighthouse.

Will a better score increase my sales?

Sometimes, and it is not automatic. Speed matters most where it is bad enough to lose people before the page is usable, which is common in in-app browsers on mobile. We report speed findings with the sessions affected and the assumptions behind the estimate rather than promising a lift from a score change.
