Retourneert een domein‑backlinkprofiel: een samenvatting overview, distributie insights, en een verrijkte lijst van individuele backlinks. Resultaten worden gecached en gedeeld met uw dashboard (Pro: 2 dagen, Agency: 7 dagen); een cache‑hit wordt gemarkeerd "cached": true en kost geen functiequota.

Dit is dezelfde data die de Backlink Checker shows in the app, and the cache is shared — a domain you have already looked at there returns instantly here, free.

Backlinkvelden

Retourneert een volledige metrische set voor een seed‑trefwoord — zoekvolume, CPC, concurrentie, moeilijkheidsgraad, zoekintentie, een 12‑maanden volume‑trend, SERP‑features en meer — plus een gerangschikte lijst van gerelateerde trefwoorden met dezelfde velden. Synchronous — reageert onmiddellijk.

Dit zijn de metrics die Keyword Research Tool worden weergegeven. Zodra u de trefwoorden hebt gekozen die de moeite waard zijn, de Rank Tracker follows their positions daily — and /rank/keywords leest die posities terug, gratis.

Zoekwoordvelden

De overview (seed‑keyword) en elke related_keywords rij deelt deze velden. Elk veld kan zijn null wanneer de upstream‑data niet beschikbaar is.

Voert dezelfde crawl uit als de Website Audit Tool — broken links, redirect chains, missing titles and canonical problems, page by page.

position_change is positief wanneer het zoekwoord is verplaatst omhoog. Een zoekwoord dat nog nooit is gecontroleerd, geeft null voor elke latest.* veld in plaats van 0 — position zero would read as "ranked first".

Dagelijkse positiegeschiedenis voor één gevolgde zoekterm, met de gerangschikte URL en de SERP‑features die bij elke controle aanwezig waren. Inclusief een vooraf berekende trend samenvatting.

Lezen trend

history is gesorteerd op nieuwste eerst. best en worst negeer niet-gerankte controles, zodat ze null wanneer het zoekwoord nooit gerangschikt was in het venster.

De Google Search Console-eigenschappen die aan uw account zijn gekoppeld, zoals weergegeven in Search Console Insights. Neemt geen parameters.

This reads SignalSumo's synced copy — it does not call Google. last_synced_at vertelt je hoe actueel die kopie is.

De merken die u volgt over AI-antwoordmachines, één rij per project, met de huidige zichtbaarheidsscore en de beweging ervan. Neemt geen parameters. Aangedreven door de AI Visibility Checker.

Scores are collected by scheduled scans, so this endpoint never calls an AI provider — it returns what the last scan stored.

Twee verschillende percentages

Deze zijn gemakkelijk te verwarren, en ze beantwoorden verschillende vragen:

latest_snapshot is null voordat de eerste scan van een project voltooid is. competitors retourneert maximaal 20, gesorteerd op vermeldingsteller. brand_share_pct is null when no mentions have been recorded on either side — a share of nothing is not zero percent.

Elke markt POST /keyword-research accepteert, zodat u een kunt ontdekken location_code in plaats van er één te raden en een 422. Neemt geen parameters.
