Technical SEO
Crawling, rendering, indexation, log files, Core Web Vitals, structured data, internationalisation and migrations.
Professional knowledge assessment
A knowledge assessment game for SEO professionals. Four clues, decreasing points, ten questions per session — and a blind-spot map that shows exactly what to study next.
The format
Every Four Clues question reveals up to four hints. Answer on the first clue and you take full marks. Need all four? You still learn — you just bank fewer points.
Broad and abstract. Only real practitioners land it here.
A sharper technical framing narrows the field.
A concrete signal or symptom you'd see in the wild.
The give-away. Points drop, understanding stays.
Verticals
Crawling, rendering, indexation, log files, Core Web Vitals, structured data, internationalisation and migrations.
Search intent, title and heading craft, internal linking, content depth, cannibalisation and E-E-A-T signals.
Generative engine optimisation, retrieval and chunking, citation earning, llms.txt, agent crawlers and AI Overviews.
Blind spots
Four Clues tracks accuracy per competency, not just per session. Your dashboard surfaces the areas quietly dragging your score down, then builds practice sessions that target them — while rotating questions so you're never re-answering what you already nailed.
Performance bands
From Needs work to Exceptional, with honest feedback.
Weak-area practice
One tap to drill your five softest competencies.
Question rotation
Recently seen questions are pushed to the back.
Explanations that teach
Why the right answer is right — and yours wasn't.
