Your popup collects emails. What is it costing you?
Paste your popups as they run today or as you plan them - the email popup, the first-order discount, the exit-intent offer, the slide-in, the announcement bar: what each one says, when it fires, who sees it, how often, how it closes and what phones get - and, if you have them, the impressions and submissions. Your browser checks the six things that make a popup work (timing, value, respect for the visitor, targeting, mobile, compliance), holds your conversion rate against the typical 2-5%, and flags what costs you: a popup on page load, no frequency cap, a close button that hides, a guilt-trip decline, an interruption at checkout, a full-screen overlay on phones, a pre-checked box. Free, before you sign in, and nothing is uploaded. Then the audit says what to fix, and the design writes the popups: trigger, rules, copy, fields, the phone version and what to test.
The sites and numbers in the examples are invented. Two are audits (the plant shop also carries its design, one click after the audit) and one is a design; each comes with a saved model reply, so you can see the whole page without signing in or spending a credit.
What this does, and what it does not
A popup earns its interruption with timing, value and respect: it appears when the visitor has shown interest (a scroll, a click, the move to leave, 30-60 seconds of reading), offers something worth the interruption in words that say what they get, closes easily, shows at most once a session, stays off checkout, and turns into a small bottom slide-up on phones rather than a wall Google penalises. This page reads each popup in your paste, finds the line that shows each of those six areas, works out your conversion and close rates against the typical range for the trigger, and raises the mistakes the skill warns about.
The paid lanes see your popups (the middle is cut past 6,000 characters, and the page says so), your context (past 4,000) and the page's scan. Your input stays in this browser unless you run a lane. Every reply is held to your input: quotes are checked word for word, and no count, rate, discount or window may be invented beyond the skill's own constants - the design writes [placeholders] for what only you know, such as the discount or a code's expiry.
