Meet de gereedheid van een website voor generatief zoeken, antwoordmachines, AI-citaties en traditioneel zoeken.
This site's takeaway scores: SEO 94/100 (grade A) and AIO 88/100 (grade B), from 9 measured visibility categories. Strongest area: Search visibility (100/100); weakest: AI & answer engines (77/100). Strong-ranking sites meet an 85-point profile on these same checks — that is the yardstick for both scores.
SEO: voldoet aan het sterk scorend profiel. AIO: voldoet aan het sterk scorend profiel. De 85-punten benchmark is de score die een site zou behalen op dezelfde controles als deze de werkwijzen volgt die consequent sterk rankende sites hanteren: een meetbare maatstaf, geen actuele concurrentierankings.
Elke categorie bestaat uit een gewogen set gemeten controles; niet-meetbare categorieën worden uitgesloten van de beoordeling en niet geschat.
Niet meetbaar op deze site, uitgesloten in plaats van geschat: Lokale zoekresultaten.
Elke score is opgebouwd uit gewogen categorieën; de bijdragekolom toont exact hoeveel punten elke categorie aan het totaal toevoegt (gewichten worden hernormaliseerd over wat meetbaar was). Categorieën hergebruiken dezelfde onderliggende controles; niets wordt dubbel gecrawld.

Elk item is getagd met de score die het verbetert (SEO, AIO of beide) en heeft een status: Te doen = staat op uw huidige plan · ✓ Gereed = de wijziging is gedetecteerd bij een hercontrole van uw site · Nog open = hergecontroleerd maar nog niet gedetecteerd · Wacht op externe data = een crawl van uw site alleen kan dit niet bevestigen.
