Traffic volume, ad cost, value per converter, and contribution margin are held constant. The scenario does not estimate the effect of a page change.

A dash means the ratio has no valid denominator or no positive allowable ad budget.

WHAT TO DO WITH THISFind one testable problem below.

Review message match, friction, proof, and measurement. Then choose one hypothesis and a primary conversion metric.

THE PAGE REVIEW / BASED ON YOUR ANSWERS

What should you test first?

Open your page on a phone and work through these checks. This is a guided review, not an automated URL scan. We do not invent a score for a page we have not inspected.

01 / VERIFY FIRSTThe conversion event matches a real completion.

Complete a test purchase or submission. Confirm it reaches the destination and is counted once.

02 / MESSAGEThe first screen delivers the promise made by the ad.

Open the ad and destination side by side. Check offer, price, product, and audience—not just matching colors.

03 / FRICTIONThe main action works on a real phone.

Try the entire flow in an in-app browser: buttons, keyboard, form validation, and checkout.

04 / PERFORMANCEThe page loads and responds acceptably for real visitors.

Check mobile field data where available. Review loading, responsiveness, and unexpected layout shifts.

05 / OFFERPrice, requirements, and what happens next are clear.

Look for late surprises: shipping, subscriptions, eligibility, delivery times, or a call instead of an instant download.

06 / PROOFThere is credible evidence near the decision.

Use a real demonstration, verifiable review, relevant case, or clear product detail. Avoid unsupported guarantees.

07 / FRICTIONThe form asks for what this step actually needs.

Identify fields that are unnecessary now. Check error messages and autocomplete. Preserve questions needed to qualify or fulfill.

08 / CLARITYThe primary button explains the next action.

Could a visitor tell whether the next step is checkout, a quote, a booking, or a download?

THE METHOD / WHAT IS INCLUDED

Understand the number
before you act on it.

Observed conversion rate = converting visitors ÷ eligible visitors. What-if conversions = eligible visitors × scenario rate. Additional revenue = change in converting visitors × revenue per converter. Additional contribution = that revenue × contribution margin, with traffic cost held fixed. This is a sensitivity calculation, not a promise that an edit will increase conversions. The page review is based on your answers; it does not crawl or inspect a URL.

Defaults are illustrative, not industry benchmarks. Choose inputs from the same reporting scope. A calculated opportunity is a question to test, not a guaranteed result.
