Free web tools (calculators) as SEO/AEO entry points into the quiz funnel
As AI search eroded blog SEO (30–40% of Built With Science's traffic), they built calculators (calories, macros) that rank well in AI answers, deliver value and hand off into the web quiz — converting slightly better than blog posts; plus Reddit as an early AEO lever.
Free web tools as entry points into the quiz
TL;DR
- Built With Science got 30–40% of traffic from SEO (old blog posts); AI search has been eroding it.1
- Response (2026): hire an external AEO (answer-engine optimisation) consultant, re-optimise existing content, and build free online tools — calorie calculator, macro calculator.1
- Tools add value (e.g. calories to eat per day to lose fat) and flow seamlessly into the quiz; they also tend to rank well in AI search.1
- Tools convert slightly better than blog posts (depends on the tool/post).2
- AEO takes time like SEO; keep investing.1
Details
Why tools fit a quiz funnel (derived). A calculator already asks quiz-like questions (weight, goal, activity) and produces a personalised result — the natural bridge into “get your full personalised plan” in the web quiz. Pre-fill the quiz with the calculator’s answers to keep momentum.
Reddit as AEO input. Phil Carter notes LLMs over-indexed on Reddit as a source (more so 6–12 months before April 2026), so guerrilla marketing and community on Reddit raised the odds of appearing in ChatGPT/Claude answers; the effect is weakening.3
Content-led loops. Phil groups SEO/AEO with viral loops as “content-driven organic loops” — Gamma’s shared presentations get indexed and cited, bringing free users.4
Disagreements / caveats
- Single-company evidence for tool → quiz conversion; no numbers beyond “slightly higher”.
- AEO tactics change quickly with LLM retrieval changes — re-check before investing.
