Method: one ordinary GET request to the public homepage. We do not log in, do not touch admin or customer data, and do not execute JavaScript — so anything loaded later by a tag manager reads as absent, and we say so wherever it applies. These companies are not clients and have not asked for this. Sites change; each entry carries the date it was scanned.

What is done well
Consent is handled properly
- Observed
- A consent management platform is present in the served markup.
- Why it matters
- Allbirds sells into the UK and EU, where setting non-essential cookies without consent is a regulatory exposure rather than a preference. A surprising number of storefronts of this size still have no consent layer at all, so this is worth noting as done right.
The measurement stack is real
- Observed
- Meta pixel and Google Tag Manager are both present, alongside a review widget.
- Why it matters
- This is a storefront where paid media can actually optimise toward purchases and where product pages have social proof to convert with. It is the baseline every store should have, and plenty do not.
The server is quick
- Observed
- First byte returned in 569 ms.
- Why it matters
- Server response is the part of performance a merchant has least direct control over on hosted platforms. There is nothing to fix here — the opportunity is in what gets sent, not how fast it starts.
Where there is room
659 KB of HTML on a single page
- Observed
- The homepage delivered 659 KB of HTML in one response, before images, fonts, CSS or JavaScript are counted.
- Why it matters
- HTML must be downloaded and parsed before anything renders, and it is on the critical path in a way that images are not. On a mid-range phone over mobile data — which is most paid social traffic — a payload this size delays the first meaningful paint measurably. For a brand buying cold traffic at scale, that delay is applied to every acquired visitor.
- In fairness
- Large HTML on Shopify frequently reflects inlined JSON for product and section data rather than sloppy markup, and some of it is doing useful work. The question is not whether it can be zero, but how much of it the first screen actually needs.
No JSON-LD found on the homepage
- Observed
- No `application/ld+json` block was present in the served homepage markup.
- Why it matters
- Structured data is what lets search results carry price, availability and rating. Absent it, listings fall back to a plain blue link while competitors show stars and prices — a difference in click-through that compounds across a whole catalogue.
- In fairness
- Homepages carry structured data far less often than product pages do, and product pages here may well be marked up correctly. This finding is specifically about the homepage we scanned, and it would be wrong to read it as a catalogue-wide gap without checking product templates.
GA4 not detected directly
- Observed
- No direct GA4 snippet was found in the served markup, though Google Tag Manager is present.
- Why it matters
- Worth verifying that analytics fires as expected, because tag manager containers are exactly where measurement quietly breaks after a theme change.
- In fairness
- This is almost certainly a false alarm. GA4 is routinely deployed through GTM rather than as a direct snippet, and our scan does not execute JavaScript, so a GTM-loaded tag is invisible to it by design. We flag it only because it is cheap to confirm.
The one thing we would do first
This is a well-run storefront, and most of what we would look at is already in place. The single finding worth acting on is the homepage payload: 659 KB of HTML is a lot to put in front of a first-time visitor arriving from a paid ad on a phone, and it is the kind of cost that never shows up in a campaign report because it is spent before the page is visible.
