Renvoie le profil de backlinks d'un domaine : un résumé overview, distribution insights, et une liste enrichie d'individus backlinks. Les résultats sont mis en cache et partagés avec votre tableau de bord (Pro : 2 jours, Agence : 7 jours) ; un hit de cache est marqué "cached": true et ne consomme aucun quota de fonctionnalité.

Ceci est les mêmes données que le Backlink Checker shows in the app, and the cache is shared — a domain you have already looked at there returns instantly here, free.

Champs de backlink

Renvoie un ensemble complet de métriques pour un mot‑clé de base — volume de recherche, CPC, concurrence, difficulté, intention de recherche, tendance du volume sur 12 mois, fonctionnalités SERP et plus — ainsi qu’une liste classée de mots‑clés associés contenant les mêmes champs. Synchronous — répond immédiatement.

Voici les métriques que Keyword Research Tool affiche. Une fois que vous avez sélectionné les mots‑clés à poursuivre, le Rank Tracker follows their positions daily — and /rank/keywords lit ces positions en retour, gratuitement.

position_change est positif lorsque le mot‑clé a bougé en hausse. Un mot‑clé jamais vérifié renvoie null pour chaque latest.* champ plutôt que 0 — position zero would read as "ranked first".

Historique quotidien des positions pour un mot‑clé suivi, avec l’URL classée et les fonctionnalités SERP présentes à chaque vérification. Inclut un pré‑calculé trend résumé.

Lecture trend

history est trié du plus récent au plus ancien. best et worst ignorer les vérifications non classées, afin qu'elles soient null lorsque le mot‑clé n’a jamais été classé dans la période.

Les propriétés Google Search Console connectées à votre compte, comme affichées dans Search Console Insights. Aucun paramètre requis.

This reads SignalSumo's synced copy — it does not call Google. last_synced_at vous indique à quel point cette copie est fraîche.

Clicks, impressions, CTR and average position for a synced property, grouped by whichever dimension you ask for. Despite the name it is not limited to queries — set dim pour décomposer les mêmes chiffres par page, pays, appareil ou date.

Les marques que vous suivez sur les moteurs de réponse IA, une ligne par projet, avec le score de visibilité actuel et son évolution. Aucun paramètre requis. Propulsé par le AI Visibility Checker.

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

score_change est null until a project has been scanned at least twice — a first scan has nothing to compare against, and reporting 0 serait lu comme « aucun mouvement ».

Deux pourcentages différents

Ce sont des notions faciles à confondre, et elles répondent à des questions différentes :

latest_snapshot est null avant que le premier scan d'un projet ne soit terminé. competitors renvoie au maximum 20, triés par nombre de mentions. brand_share_pct est null when no mentions have been recorded on either side — a share of nothing is not zero percent.

Tous les marchés POST /keyword-research accepte, afin que vous puissiez découvrir un location_code au lieu de deviner un et de gagner un 422. Aucun paramètre requis.
