Replaced 963 anonymous structured‑data blocks that restated the company 1,671 times with one linked graph of 16 types minted from stable origin identifiers.

Situation. The site emitted structured data the way most sites do: a block per page, each one describing the organisation again from scratch. Across the site that came to 963 blocks restating the same company 1,671 times, anonymously — no stable identifier anywhere, so nothing consuming it could tell that the organisation on one page was the organisation on another.

Task. The structured data had to become one graph with stable identity, rather than a pile of blocks that happen to contain the same words.

Action. Identifiers are now minted from the site’s origin — one for the organisation, one for the site, one for the person — and every block references them rather than restating their contents. The identifiers are origin‑wide rather than per language, because the company is the same company in Danish. Sixteen types are in play, covering the service catalogue and its offers, the reviews and the work they describe, the collections and their breadcrumbs. Two decisions kept the weight down. List pages publish their items by URL only rather than inlining them, which was measured: naming them on the portfolio index would have meant 107 full statements and a 52 per cent increase in the compressed page. And the check that guards it does not merely validate syntax — it asserts that every block parses, that every identifier resolves, and that every URL the graph names was actually built, so a graph pointing at a page that does not exist fails the gate.

Result. One graph with stable identity replaces 963 anonymous restatements, and the pages carry less rather than more. The measurement that started the work is worth keeping in mind: the site had been emitting the same organisation description 1,671 times without anything being able to join them up.
