Counts are exact rows from the dataset, not derived from the percentages shown. Sample scope: 8,226 of these 9,510 storefronts run Shopify; the rest are other platforms in the same crawl. Shopify-only product markup: 3.9% (318 of 8,226).
Canonical tags sit at 96.9% and Open Graph at 92.4%. Those ship with most themes. Product markup sits at 3.6%. INFERENCE The pattern points at the same cause in most stores: themes and apps cover the generic tags, and nobody owns the one block that carries price and availability. This is a reading of the counts above, not a test of cause.
A store can carry Product markup on its product pages and still show nothing on the homepage. Read every number here as "not visible from the homepage", not "the developer forgot".
