Fibr changes the page at runtime. WhyIQ tells you what to change.
Fibr and WhyIQ sit at different points in the conversion-improvement loop. Fibr personalizes a landing page at runtime based on ad source, LLM referral, or inferred visitor intent. WhyIQ simulates 50 distinct visitor archetypes against the page in about 2 minutes and reports which ones would bounce and why. Works on established sites, pre-launch URLs, and Fibr-generated variants in staging. The two are sequential, not competing: diagnose with WhyIQ, then optimize with Fibr or any other action layer.
| Fibr | WhyIQ | |
|---|---|---|
| Primary job | Optimize the page at runtime | Diagnose why the page fails |
| Stage in the CRO loop | Action (change the page) | Diagnosis (understand the page) |
| Visitor view | Per-visitor intent (ad / LLM source) | Per-archetype (50 distinct profiles) |
| Works on established sites | Yes | Yes |
| Works pre-launch | Needs live traffic to personalize | Yes, any URL |
| Changes the live page | Yes, at runtime | No, diagnostic only |
| Output shape | Adaptive page variants | Prioritized failure-mode list with fixes |
| Multi-page audit | Per-page personalization layer | Site scan covers up to 50 pages |
| Time to first insight | Setup + traffic accumulation | About 2 minutes |
| Starting price | Contact sales | From $19 per month |
The diagnostic step before optimization is even worth running
Fibr optimizes the page. WhyIQ tells you what to optimize toward, what to fix manually first, and which variants pass behavioral review before they reach production.
The 'why is this page failing?' diagnosis
Runtime personalization optimizes against perceived intent without naming the failure modes of the base page. WhyIQ reports which copy confused which archetype, which trust signal was missing, which CTA failed the scent test, so the optimization layer has something to personalize toward.
The pre-deploy variant validation step
Before letting a runtime layer ship a variant to live traffic, run WhyIQ on the staging URL. The 50 archetypes catch regressions in the variant against the base, so a bad variant never reaches production.
The per-archetype why behind aggregate intent
Intent inferred from ad source or LLM referral collapses many distinct cognitive profiles into one bucket. WhyIQ separates 50 archetypes (impulse buyer, skeptical evaluator, comparison shopper, regulated B2B procurement, and others) so the variant strategy can be informed, not guessed.
The 'know what is broken before you fix it' step
Optimization without diagnosis is brute-force search. WhyIQ produces the failure-mode list first, so the team can decide which fixes belong in manual edits, which belong in runtime variants, and which need a copywriter or developer pass.
What WhyIQ does not replace
Fibr is an action layer that changes the page at runtime. WhyIQ is a diagnostic layer that produces failure modes. Both have value; neither replaces the other.
Runtime landing page personalization that adapts content per visitor at request time
Ads-to-web intent matching that carries ad-source signal through to the landing page
LLM-referral-aware copy adaptation for AI search traffic
Multi-armed bandit traffic routing and in-session variant optimization
The operational layer of serving different page versions to different visitors automatically
When each is the right call
Use WhyIQ when
- Auditing a base page before deciding whether runtime personalization is worth the integration
- Validating a redesign or new landing page before deploying it to live traffic
- An established page underperforms despite personalization already running
- You need a diagnosis to inform what runtime variants should personalize toward
- Auditing a full site (up to 50 pages per scan) for cognitive friction patterns
Use Fibr when
- The base page already performs adequately and you want a runtime lift
- Ad source and LLM referral are reliable signals for variant selection
- Per-visitor page adaptation at request time is the workflow
- Multi-armed bandit traffic routing is part of the conversion stack
- An action layer is needed, not a diagnostic report
