Pillar breakdown

Each pillar shows the points earned against the maximum that was actually observable. Where a signal could not be observed it is removed from both sides rather than scored as a failure.

The pages we sampled

Drawn by seeded random selection from your own product sitemap — 50,000 candidate product URLs, seed "anglera-legibility-2026". Same seed, same pages, every time. Open any of them and check our arithmetic.

What would move this number

  • Publish a valid GTIN on every page. 38% of your sampled pages carried one that validates. It is the field an agent uses to match your product to the same product at three competitors.
  • Fill in the recommended Product fields. Your markup is present but shallow — shipping, returns, condition and price validity are the ones most often missing.
  • Express variants as a ProductGroup. Size and colour are the retail catalog, and without hasVariant an agent sees unrelated products.
  • Put ratings in the markup, not just the pixels. Reviews are the single biggest factor shoppers cite, and only 0% of your sampled pages expose them where a machine can read them.

What this score is not

It is not an audit and not a judgement of the business — it is a 8-page sample taken on a stated date, scored on a published rubric with no model judgement in it. Nothing here predicts whether any assistant will recommend you; for most answer engines that is decided by a private merchant feed we cannot see. If a number here is wrong, tell us and it goes in the public corrections log.

Go deeper than eight pages

This scorecard is a sample — eight product pages, drawn at random from a published seed. It tells you where Walmart stands, not which SKUs are costing you. We’ll run a real sample of the whole catalog through the same extractor and send back the fields that are missing, by product.

Everything above stays free either way — the rubric, the sampled pages, the dataset, and every other company’s scorecard.
