# Pop-up

> A pop-up is a window displayed over a web page that grabs the user's attention with a message, form or offer.

A **pop-up** is a window displayed over a web page that grabs the user's attention with a message, form or offer. It typically appears above the main content after a specific action — arriving on the page, scrolling through part of it, or attempting to leave the site — and is one of the most widely used tools for collecting contacts and boosting [conversion](https://nodea.io/en/glossary/conversion).

## How a pop-up works

A pop-up is an interface element triggered by a specific event and layered over the page content, often with a dimmed background. Its trigger is what matters most:

- **Exit intent** — the window appears when the cursor moves toward closing the tab.
- **Time-based** — after a defined amount of time on the page.
- **Scroll-based** — after scrolling a set percentage of the content.
- **Click** — after interacting with a button or link.

A well-designed pop-up includes a clear [call to action](https://nodea.io/en/glossary/call-to-action) and a visible close button so it does not frustrate visitors.

## Pop-ups in practice

Pop-ups serve various marketing and informational goals:

1. **List building** — a sign-up form window, often paired with a [lead magnet](https://nodea.io/en/glossary/lead-magnet).
2. **Promotions** — discount codes and time-limited offers.
3. **Consents and notices** — cookie banners, legal messages and web push prompts.

The key is moderation: too many pop-ups worsen the [user experience](https://nodea.io/en/glossary/ux) and can lower search rankings. The best results come from precise targeting and testing different variations of content and timing.

## Types of pop-ups

In practice you meet several distinct variants that differ in form and intrusiveness:

- **Modal** — a central window that dims the background and blocks interaction with the page until closed.
- **Slide-in** — a discreet box that slides in from a corner of the screen, less invasive for the user.
- **Full-screen (welcome mat)** — an overlay covering the whole screen; effective but risky for SEO on mobile.
- **Floating bar** — a slim bar at the top or bottom of the page with a message and a button.

The choice of form should follow the campaign's goal and the audience's sensitivity — the more important the message, the more visibility you can justify, but always with an easy way to close the window.

### Do pop-ups hurt SEO?

Intrusive pop-ups that block content right after arrival (known as intrusive interstitials) can lower Google rankings on mobile. Discreet pop-ups triggered after interaction or covering only a small part of the screen are usually not penalised by the algorithm.

### When is the best time to show a pop-up?

Effectiveness depends on the trigger. Popular moments include exit intent, scrolling through part of the content, or a delay of several dozen seconds. A pop-up shown too early, before the user engages with the offer, tends to annoy rather than convert.
