Website popup generator (notice, coupon or newsletter)

Website popup generator (notice, coupon or newsletter): what it is for

A well-made popup promotes a coupon, news or your newsletter without scaring visitors away. Write the title, text and button, and choose when it appears: after a few seconds, after scrolling part of the page or on exit intent (desktop).

The code uses the dialog element (closes with Esc, keeps focus inside the popup), stores in the browser when the visitor closed it so it only repeats after the days you choose, and becomes a bottom bar on mobile, because Google considers popups that cover the main content on mobile intrusive. The animation respects people who prefer less motion.

How to use

1. Write the message and the button.
2. Choose when it appears and the days interval.
3. Copy the code to the end of the body.

When to use it

• A first-purchase coupon.
• News or special hours announcements.
• An invitation to your newsletter or WhatsApp.

Frequently asked questions

Do popups hurt my site on Google?

They can. Google treats popups that cover the main content as 'intrusive interstitials', especially on mobile and right when someone arrives from search, and that counts against page experience. That's why the code shows a small bar on mobile and lets you delay the popup by time or scroll.

How do I keep the popup from showing all the time?

The code stores in the visitor's browser (localStorage) when they closed the popup and only shows it again after the number of days you choose. People who clicked the button don't see it again.

What is the exit intent option?

On desktop, the popup appears when the mouse moves toward the address bar or tabs, a sign the person is leaving. Phones don't have that movement, so the popup opens after a few seconds.
