I Gave Away My Best Sales Tool

The hardest part of selling a website is not the build. It is the conversation before the build.

A business owner knows something is off. Traffic comes in, nobody calls. The site loads — eventually. The WhatsApp button sits at the bottom of a page nobody scrolls to. They feel the problem. They cannot name it.

And I cannot name it for them — not without looking first.

So I built a tool that looks.

What Signal Lens does

Go to lawrencenwuzor.com/services. Scroll down to Signal Lens. Paste any URL.

In ten seconds, you get a full diagnostic — five scores rendered as animated rings, Core Web Vitals broken down to the millisecond, every missing security header named, every SEO gap surfaced, every issue ranked by severity.

Critical issues in red. Warnings in gold. Informational notes in teal. No ambiguity. No jargon without explanation.

At the bottom, a verdict — which tier of service would fix what the tool found, and a single button to start the conversation.

How it works under the hood

Two data sources run in parallel. Google's PageSpeed Insights API handles the heavy analysis — Lighthouse scores for performance, SEO, accessibility, and best practices. Core Web Vitals come from the same pass: First Contentful Paint, Largest Contentful Paint, Cumulative Layout Shift, Total Blocking Time.

Simultaneously, a direct fetch hits the URL from the server side. This is where the security analysis lives — HTTPS status, HSTS headers, Content Security Policy, X-Content-Type-Options, referrer policy. The same fetch parses the raw HTML for SEO signals: title tags, meta descriptions, Open Graph images, viewport configuration, canonical URLs, structured data.

Both streams resolve. The results merge. An issue generator scans every data point against thresholds I set — thresholds based on what actually costs businesses traffic in Nigeria and across Africa, not theoretical benchmarks from Mountain View.

The verdict engine counts critical and warning issues, weighs the performance score, and recommends a tier. Not a sales pitch — a diagnosis.

Why I made it free

The conventional move is to gate this behind a form. Collect the email. Nurture the lead. Schedule the call. Run the audit yourself. Present the findings on a slide deck. Bill for the consultation.

I find that approach dishonest.

If the diagnosis takes ten seconds, why am I pretending it takes a meeting? If the data is public — PageSpeed is free, security headers are visible to anyone with curl — why am I packaging publicly available information as premium insight?

The insight is not the data. The insight is knowing what to do about it.

Signal Lens tells you your site loads in 6.2 seconds on mobile, that you are missing HSTS, that you have no Open Graph image so every WhatsApp share renders as a blank box. That is not a secret. That is a mirror.

The value I sell is not the mirror. It is the rebuild. The architecture that makes the scores turn green. The seven days between diagnosis and a site that actually converts.

Giving away the diagnostic does not reduce my leverage. It increases it. A prospect who has already seen their own scores does not need convincing. They need a builder.

The technical choices that matter

I could have used a third-party audit API and white-labeled the results. I chose to write the analysis logic myself for a reason — I needed control over what counts as a problem.

Most audit tools flag missing CSP headers as critical. For a five-page portfolio site in Lagos, that is noise. A missing viewport tag — that is critical, because 80% of Nigerian web traffic is mobile and a site without viewport configuration is unreadable on every one of those phones.

The thresholds are opinionated. They reflect what I have seen break real businesses, not what a generic checklist says matters.

The frontend is equally deliberate. Framer Motion handles the score ring animations — each ring draws from zero to its final value with staggered timing. Issue cards slide in sequentially. The loading state pulses a Nsibidi glyph while the analysis runs. Every interaction is designed to feel like the tool is working, because it is.

No loading spinner. No progress bar counting to a fake 100%. A symbol that breathes while two API calls resolve in parallel.

Go break it

The tool is live. It works on any public URL. Paste your site. Paste a competitor's site. Paste the site of the agency that charged you three million naira and delivered a WordPress template.

If the scores come back green — your site is solid. If they come back red — now you know exactly where the money is leaking.

Either way, the mirror does not lie.
