The math behind pricing a website fix

The reason most website advice gets ignored is that it's unpriced. "Improve your CTA" competes with a hundred other unpriced to-dos and loses. Price it, and it moves to the top of the list.

Here's the actual math — and the rules that keep it honest.

The core formula

Every money-linked website estimate rests on one chain:

monthly visits × conversion rate × close rate × value of one win

• Visits — how many people reach the site each month. If you don't have analytics, traffic can be estimated from the site's footprint (we do this so we never have to ask a prospect to guess their own numbers).
• Conversion rate — the share of visitors who take the primary action (inquiry, booking, add-to-cart). This is the number most website issues move.
• Close rate — the share of those actions that become paying customers. For e-commerce it's 1 (the order is the win); for services there's a step from inquiry to job.
• Value of one win — a commission, a first-year patient, an order, a signed case.

Multiply them and you have the revenue the current traffic is worth. Change the conversion rate to reflect a fixed issue, and the difference is what the issue is costing.

Where the numbers come from

None of these are invented:

Input	Source
Conversion rate	Published industry CVR benchmarks (they vary a lot by sector — hence niche-specific models)
Close rate	Sector norms (e.g. inquiry→booked for local services)
Win value	Owner knowledge, or defensible sector averages
Speed / SEO signals	Measured directly from the live page

The overlap rule (so totals stay conservative)

If you find five issues and naïvely add up each one's dollar impact, you'll double-count — the same lost visitor can't be lost five separate times. A conservative total takes the largest single issue in full, plus a fraction of the rest. The result always sits between "the biggest problem alone" and "the raw sum," which is where an honest number belongs.

The leak-vs-prize rule

If a site genuinely can't convert — no form, no phone link, no booking path — there's no loss to measure. Inventing one would be dishonest. Instead, flip the framing: "adding a booking path is worth ~$X/mo." Same math, but it's a prize to capture, not a loss to stop.

The precision rule

Always a range, always with assumptions attached. A single confident number with no visible inputs is a red flag, not a selling point. A range you can pull apart and check is what earns trust — especially from a skeptical owner.

Put it to work

That's the method. The inputs are what make it real — and the fastest way to get your real inputs is to measure the live site.
