How to read this site
Two things on every claim tell you how far to trust it: the label says who is speaking, the grade says whether Google’s documentation backs it.
Search Central Live Deep Dive Europe 2026 ran for three days in Barcelona. This site turns what was shown and said there into claims: short, self-contained statements, each with an ID, a label for who is speaking and a grade for how it stands against Google’s documentation.

Labels: who is speaking
Slide
Shown on screen. Shown on a slide at the event, by Google or a community speaker, taken from a photo of the slide.
Stage
Said on stage. Taken from the author’s notes, a transcript or a recording. The speaker is named when known; audience questions say so.
Docs
Google's documentation. Google’s own published pages, with a link. Placed next to the session it explains; it was not said there.
Press
Reported by the press. A third-party publication, such as a search industry news site, reporting what Google or a Googler said. Useful context, but not Google’s own words on record.
Analysis
The author's interpretation. Advice and interpretation by Ibrahim Anjro. Never attribute it to Google.
Verification: is it in Google’s documentation?
Every technical claim made at the event was checked against Google’s public documentation.
Confirmed by docs
Google's documentation states the same thing.
Consistent with docs
Google's documentation supports it without stating it directly.
Not in docs
Said or shown at the event, but not in Google's documentation. Quote it as said at Search Central Live, not as documented policy.
Source
The claim is the cited document itself: a page of Google documentation or a press report.
No badge
Nothing to verify: a quotation, framing, agenda fact, audience question, opinion or analysis.
Links between claims
Claims point to each other when a later talk returns to an earlier point, and answers point to the audience question they answer. The Across days page lists every link.
Contradicts
A claim that disagrees with an earlier one. The other claim shows “Contradicted by”.
Updates
A claim that replaces or revises an earlier one. The other claim shows “Updated by”.
Extends
A claim that adds detail to an earlier one. The other claim shows “Extended by”.
Repeats
The same point made again, often on a later day. The other claim shows “Repeated by”.
Answers
An answer to a question from the audience. The other claim shows “Answered by”.
Under a claim, Used by lists what rests on it: the developer requirements, facts, myths, quotes, story angles and glossary terms of the two kits that cite it. Each topic page lists the requirements and facts built on its claims, and each source lists the claims it backs, by grade.
Things
A thing is a product, feature, crawler, report, directive, status code, standard, metric, concept, update or tool the event talked about, such as Search Console, Googlebot, hreflang or 429. Under a claim, Things lists the ones it names, matched word for word by name or other name. Each thing has a short card: what Google’s documentation says, what was only said at the event, the kit items built on those claims and the things named with it most often. A card is a map, not a source: cite the claim IDs on it. All things.
The Reef mapGraph shows the same links as a map, one neighbourhood at a time: a thing, topic, kit item, document or claim in the centre and everything linked to it around it, with the full list beside the map. Click a neighbour, or tab to it and press Enter, to put it in the centre; the browser’s back button returns. Every thing’s card and every topic page has an “Open in” button that starts it there. Drag the background to pan, scroll or pinch to zoom, and drag a bubble to move it. Point at a bubble for a preview; its + grows its neighbours where it sits, and a right-click (a long press on a phone) opens a menu to open, pin or hide it. A trail along the top lists the centres you visited.

Citing a claim
Every claim has a permanent ID such as D1-C094: Day 1, claim 94. IDs never change or get reused. Link to claims.html#D1-C094 on the All claims page.
What is deliberately not here
No slide photographs, no transcripts, no private notes and nothing about other attendees. Claims are paraphrased, with quotations of 25 words or fewer only where the wording matters. Companies shown on stage as examples of broken sites are not named.
