A high-converting website that learns every visitor
FangoLabs builds AI-engineered websites and runs conversion rate optimization that turns your traffic into booked calls and qualified leads — fast pages, adaptive copy, and an agentic chat that qualifies visitors 24/7.
AI Web & Conversion Engineering is FangoLabs' service for building a high-converting website and continuously optimizing its conversion rate using AI. A redesign that only looks better is a cosmetic change; we design for the funnel and engineer for the model, so the site adapts copy, offers, and calls-to-action to each visitor and qualifies leads through an agentic chat layer trained on your sales playbook. The result is more booked calls and form fills from the traffic you already have.
We start by mapping your funnel and finding where visitors drop, then rebuild on a fast, modern stack that hits Lighthouse 90+ and loads in under two seconds — because speed is the first conversion lever. From there, conversion rate optimization runs continuously: prompt-driven A/B tests, heatmaps, session recordings, and agent-led recommendations that keep your conversion rate climbing after launch instead of going stale.
Unlike agencies that ship a pretty site and walk away, FangoLabs treats the website as a system that compounds. You own the site, the data, and the personalization logic. Whether you need a full rebuild or CRO on an existing site, every engagement starts with a free site and funnel audit that shows exactly where you are leaving revenue on the table — and what we would change first.

Key Technology Differentiators
Why we outperform generic agencies utilizing manual operations
⚡ Engineered to convert, not just to look good
Every build starts from your funnel math, not a template. We design the page around the next click — the qualifying question, the offer, the booked call — so the redesign moves revenue, not just bounce rate.
⚡ Agentic chat that qualifies and books 24/7
Not a scripted bot. A model trained on your sales team's playbook that answers questions, qualifies the visitor, and books the call while you sleep — turning anonymous traffic into pipeline.
⚡ Continuous CRO, not set-and-forget
Most agencies ship a site and walk away. Our prompt-driven A/B framework, heatmaps, and agent-led tests run after launch, so your conversion rate keeps climbing month over month.
⚡ You own everything
The site, the code, the data, and the personalization logic are yours. No proprietary lock-in, no platform you can't leave — your conversion gains stay with you.

How We Work
A transparent, repeatable delivery process engineered for speed and measurable outcomes.
We analyze your current site speed, traffic, and funnel to find exactly where visitors drop and where personalization and CRO will move the needle. You get the findings whether or not we work together.
Sitemap, wireframes, content plan, personalization matrix, and performance budget — including the conversion goals and KPIs we're engineering toward — all agreed before a single pixel moves.
Design and development run in parallel on a fast modern stack. We configure the AI personalization engine and agentic chat, and wire up conversion tracking. You see weekly previews.
We ship the site at Lighthouse 90+ and sub-2-second loads, with the qualifier live and every conversion event tracked from day one.
Post-launch, we run prompt-driven A/B tests, heatmaps, session recordings, and agent-led CRO to lift the conversion rate on real traffic — not assumptions.
Monthly performance and conversion reporting with clear next experiments. Strategy stays with our team; the agents surface what's working so every month compounds.

Frequently Asked Questions
- You can start small with $0 setup: a one-time Conversion Sprint at $1,497 (audit, roadmap, and two quick-win tests), or an ongoing CRO retainer at $297/mo (CRO Lite) to $597/mo (CRO Growth). A full design-to-launch rebuild is quoted from around $8,000, and the Conversion Engine managed program runs from $2,500/mo for higher test velocity. Every engagement begins with a free site and funnel audit, so you get a scoped quote and a clear picture of the expected return before committing.
- A typical design-to-launch project takes four to eight weeks depending on scope. Early conversion lift from quick wins — speed, clearer CTAs, the agentic qualifier — often shows within the first two to four weeks after launch, while compounding gains from continuous A/B testing build over the following 60 to 90 days. We report on real conversion data, not vanity metrics.
- It includes a funnel audit, conversion-focused site architecture and design, a full UI system in light and dark, an AI personalization engine, an agentic chat lead-qualifier trained on your sales playbook, Core Web Vitals optimization to Lighthouse 90+, CRM and analytics integration, a prompt-driven A/B testing framework, and a 60-day post-launch CRO sprint. You can also engage us for CRO only on an existing site.
- AI works in three places: a personalization engine that adapts copy, offers, and CTAs to each visitor segment in real time; an agentic chat agent trained on your offering and sales process that qualifies visitors and books calls 24/7; and an AI-assisted optimization loop that proposes and runs A/B tests on live traffic. The AI does the heavy analysis; our strategists make the calls.
- Yes. You own the site, the code, the content, the conversion data, and the personalization logic outright. We build on standard, portable technology with no proprietary lock-in, so you can host it, edit it, or move it anywhere. Any conversion gains and the audience data behind them stay with your business, not ours.
- Yes. Many clients start with a CRO-only engagement: we audit the current site, add the agentic chat qualifier and personalization layer, fix speed and friction points, and run continuous A/B testing — no migration required. If the audit shows the existing foundation is holding conversions back, we'll tell you plainly and scope a rebuild only if the math justifies it.
