Tab Teaser

Description

Tab Teaser is a lightweight engagement plugin that pulls visitors back when they switch to another browser tab. The moment your tab loses focus, Tab Teaser swaps the page title (and optionally the favicon) to a custom, attention-grabbing message. When the visitor switches back, everything is restored instantly.

It is especially effective on cart, checkout, signup, and long-form sales pages where every distracted visitor matters.

Key features

• Custom inactive title — show any message (emoji supported) when the visitor leaves the tab.
• Optional flashing animation — alternate between active and inactive titles to grab attention in a crowded tab bar.
• Trigger delay — wait N seconds after the tab is hidden before swapping. Visitors who tab back in time never see the change.
• Bundled SVG favicons — three hand-crafted icons (Alert, Shopping Cart, Raised Hand) ship with the plugin. Crisp at every size, zero HTTP overhead.
• Custom favicon upload — pick any image (PNG, JPG, ICO, SVG) from the WordPress Media Library.
• Live preview — see exactly how your tab will look as you edit settings. Includes a “Simulate Tab Switch” button.
• Rich page targeting — run on every page, on selected pages / posts / custom post types / taxonomy terms, or on URL patterns (/checkout/*). Independent exclude rules always win over includes.
• No external requests — every asset is local. No tracking, no telemetry, no third-party scripts.
• Accessible & lightweight — vanilla JavaScript on the frontend, ~3 KB minified payload, no jQuery dependency.
• Multisite-aware uninstall — every option is removed cleanly when the plugin is deleted.

Privacy

Tab Teaser does not collect, store, or transmit any visitor data. It does not make any external HTTP requests. It only reads the browser’s standard visibilitychange event to decide when to swap the tab title and favicon.
