Popup and conversion encyclopedia

Eleven terms you meet when you build a popup or read what it converts, from the lightbox popup and the floating bar to click-through rate and the A/B split test. Each term is defined in plain words first. Where our data covers it, the definition comes with what we measured across the popups we power, from the 2026 popup conversion benchmark.

Every term is written by Emre Elbeyoğlu, Popupsmart's founder, and reviewed by Mert Özeren from our customer success team.

For the longer version of a topic, read the conversion rate optimization guide or the email marketing guide. To put a term to work, start from the popup templates or follow a popup recipe step by step. To keep the wider glossary in one file, get the digital marketing encyclopedia e-book.
