Stop Chasing Your Shopify Page Speed Score

Shopify took its single admin speed score offline on January 31, 2024. The score is gone from the dashboard. But the Fiverr gigs that promise to "boost your shopify page speed to 90+" are still online, with thousands of reviews and five-figure annual revenue per seller. The Etsy and Shopify Exchange listings for "turnkey" stores still cite a PageSpeed Insights number as if it were Shopify's own. Agency decks still benchmark themselves on PSI. A whole optimization economy outlived the thing it was supposed to optimize.

This post sets aside whether your store is fast. The question it digs into is how merchants get sold a number, and why the number you bought is almost never the number Google uses.

The score that was retired and the score that gets sold

Shopify replaced the admin score with the Web Performance Dashboard at Online Store > Themes. The new view does not give you a 0-to-100 number. It shows LCP, INP, and CLS values from the Chrome User Experience Report, drawn from real Chrome users browsing your store over the last 28 days. The reasoning, in Shopify's own announcement, was that the old number caused "confusion and frustration." I would put it more sharply: the old number was being gamed.

The optimization industry did not stop. It pivoted. The number on the Fiverr listing today is PageSpeed Insights. Same shape of pitch, same screenshot, different source. A merchant looking at a Fiverr gig titled "I will boost your Shopify store to 90+ PSI in 24 hours" sees a before/after grid of PSI screenshots. They do not see what their real customers see, which is the only number Search Console actually ranks on.

If you are still grading your shopify page speed against a number you saw in 2022, you are grading yourself against something that has not existed since the year before last. If you are grading it against the number a $50 gig sent you, you are usually grading yourself against a screenshot that the store itself never has to live up to.

What a $50 "optimization" actually buys you

In September 2025, a freelancer posted a 108-upvote confession on r/shopify describing the inside of the Fiverr speed-optimization business. They were a former seller. The work, in their own words, was a four-line edit to theme.liquid that detected when PageSpeed Insights or GTmetrix was testing the page and served a stripped-down version to the test bot. Real customers saw the actual store and the actual performance. The merchant got a screenshot. The store did not change.

Shopify's own performance team estimated in March 2024 that roughly 15% of "optimization" extensions and services use the same pattern. They worked with the Chromium project, the Lighthouse team, and GTmetrix on detection. Community evidence from late 2025 suggests the gigs adapted and kept selling. We have personally pulled the same kind of script out of two stores in the last twelve months, both belonging to merchants who paid for "speed optimization" the previous year and never saw their conversions move.

I am not going to walk through the exact signature here, because the technical detective work belongs in its own post. If you want to see what one of these scripts looks like inside an actual theme.liquid, the eight-lines-of-theme.liquid case study is the post for that. The summary you need today is: a script that lies to test bots is small, cheap to write, easy to inherit, and impossible to spot if you only look at PSI screenshots.

Why the score still gets sold

I keep meeting merchants who know all of this and still buy the gigs. The reason is structural, not stupid.

A 0-to-100 number is something a merchant can show their accountant, their co-founder, or the agency they are evaluating. "My CrUX p75 LCP is 2.4 seconds" is not a sentence anyone outside of performance engineering finds reassuring. "My shopify page speed is 92" sounds like an A on a report card. The retired admin score had at least the virtue of being Shopify's. PSI is Google's, which feels nearly as authoritative. The merchant brain reaches for the number it can put in a slide.

The same dynamic shapes the secondhand-store market. Etsy and the Shopify Exchange both let sellers list "store assets," and PageSpeed Insights screenshots are routinely part of the listing. I have read listings priced at $4,000 to $40,000 where "optimized to 90+ PSI mobile" was named as a feature in the headline. Some of those stores were really optimized. Some carried a four-line cloaking script that the buyer inherited along with the inventory. There is no due diligence checklist published anywhere on either marketplace that catches the second case. We have helped two buyers find one. Both bought the store under a "PSI 90+" claim and learned the truth from their Search Console data three months later.

Agencies pitch the same way. The deck shows a before/after PSI graph because PSI screenshots photograph well. Search Console graphs do not photograph well. CrUX dashboards do not photograph well. The metric that actually ranks your store is the worst metric for marketing materials, which is why so few agency decks lead with it.

The number Google uses, in one sentence

The shopify page speed reading that affects your search rankings is the LCP, INP, and CLS values in your Web Performance Dashboard, drawn from CrUX. PageSpeed Insights and GTmetrix are diagnostics. The deeper reason the tools disagree, and how to read each one, is covered in the methodology primer post. The detail that matters for this post is shorter: if your dashboard says "Poor" while your PSI says 87, a screenshot did not save you.

If you bought your store from someone else, or you paid for "speed optimization" in the last two years and your conversions did not move, the first 15 minutes with a help1 expert is free and that is plenty of time to look at your theme.liquid and your Search Console together. We are not going to sell you a screenshot.

What I tell merchants now

A few things, none of them new:

Treat any single shopify page speed score as a diagnostic, not a benchmark. If your PSI is 41 and your Search Console says LCP is "Good" at p75 2.1 seconds, your store is fine and you should stop refreshing PSI. If your PSI is 92 and your Search Console says LCP is "Poor" at p75 4.7 seconds, your store is not fine and the 92 is a lie someone is telling on its behalf.

If you are evaluating a store to buy, ask for Search Console screenshots over the last 28 days before you ask for a PSI run. Most sellers cannot produce them because they have never connected Search Console to the store. That is its own signal.

If you are evaluating an agency, ask what before-and-after data they will commit to. If the answer is a PSI screenshot, the answer is no. If the answer is a Search Console field-data screenshot 28 days after their work ships, the answer is probably yes. The market has not caught up to this distinction yet. Use that to your advantage.

The optimization industry built around a retired number is not going to retire itself. It runs on screenshots, and screenshots are the cheapest thing in the world to manufacture. The defense is not to buy a more expensive screenshot. The defense is to stop trading on the number entirely, and read the data that nobody can fake.
