Popup Conversion Diagnosis and Copy Rewrite
Finds where your popup, slide-in, or banner leaks conversions, then delivers the trigger spec, offer, and paste-ready copy to fix it.
Before & after
Same prompt, same agent — the only difference is the skill.
A 1% popup conversion rate is on the low side. Here are ways to improve it: - Test your timing — exit intent often works better than immediate - Make the offer compelling (a discount or valuable resource) - Simplify to a single field - Improve the copy and headline - Make it easy to close so it doesn't annoy - Test on mobile separately Try A/B testing different versions to see what resonates. The offer and timing usually matter most. What does your current popup say?
Popup CRO. Scope note: this is popups/modals specifically — for the
signup form itself see form-cro, for the whole page see page-cro.
1% means the offer or the trigger is wrong. Diagnose the trigger first.
TRIGGER — the biggest lever, and the most misused
Immediate-on-load → interrupts before any interest is built. Worst
converter, most common setting.
Exit-intent → fires when the cursor leaves. Catches the leaving
visitor with nothing to lose. Usually 3–5x an
immediate popup.
Scroll-depth 50% → fires only for engaged readers. Highest intent.
→ Move off immediate-on-load first. That change alone often doubles it.
THE OFFER
"Sign up for our newsletter" is a 1% offer — it asks and gives nothing.
Replace with a specific value exchange: the discount, the guide, the
result. The reader trades an email for something they can name.
FIELD COUNT
One field. Email only. Every added field cuts conversion; ask for the
rest later.
MOBILE
Score it separately. A desktop popup that works can be an
un-closeable, un-converting mess on mobile — and mobile is most of your
traffic.
TEST ORDER
Trigger → offer → copy. Ship the exit-intent trigger alone first; you'll
see the move in a week without confounding it with a copy change.About this skill
Your popup shows up on every page, people close it in a second, and the few sign-ups you get never seem to buy. Most popup advice says to rewrite the headline. Often the real problem is the trigger, the pages it fires on, or a discount that loses money on every order. This skill works out which stage is losing people and fixes that stage.
What it does
- Uses your numbers to find which stage is leaking: the popup fires, is seen, gets a sign-up, gets redeemed, or turns into revenue
- Sets triggers by page type and device, including what to do on mobile, where real exit intent isn't possible
- Lists who should never see the popup: checkout pages, existing subscribers, people arriving from your own emails, paid-ad landing pages
- Checks the discount against your margin before recommending a bigger offer
- Writes paste-ready copy: headline, subhead, CTA, a neutral decline link, the success state, and alternate headlines that try different angles
- Flags mobile interstitial risk, accessibility gaps, and consent wording for SMS and EU/UK sign-ups
What you get
A short diagnosis that names the leaking stage, a spec (pages, triggers, suppression) you can enter in your popup tool, finished copy with variants, and the metric to judge it by: revenue per visitor, not sign-up rate.
Best for
E-commerce store owners, content and newsletter sites, and growth marketers who run email-capture, exit-intent, or announcement overlays in tools like Klaviyo, Privy, OptinMonster, or a custom modal.

description: Finds why a popup, modal, slide-in, or banner underperforms by checking each stage of its funnel (fires, viewed, submitted, redeemed, revenue), then writes the fix: offer, trigger and targeting spec, and paste-ready copy with variants. Use when the user says "write copy for my email popup", "my exit-intent popup isn't converting", "what should trigger my popup", "everyone just closes our popup", "set up a discount popup for my store", "is our mobile popup hurting SEO", "review this modal", or "word our announcement banner".
