Why landing pages exist
The web's default page type is the homepage — a brand front door for any visitor at any stage. Landing pages exist because that default is a poor fit for paid traffic, email campaigns, and any context where you know what the visitor wants and what you want from them. Landing pages collapse the visitor journey from "explore the site" to "take this one action."
The five common types
(1) Lead-gen pages: capture contact info via a form. (2) Click-through pages: warm up the visitor before sending to a checkout or signup page. (3) Squeeze pages: laser-focused on email capture in exchange for a lead magnet. (4) Sales pages: long-form persuasion for a specific product or service. (5) Thank-you pages: post-conversion pages that re-engage or upsell.
The deciding factor
Whether you need a landing page is mostly a function of your traffic source. Paid traffic, email, social ads, partner referrals — always send to a landing page. Brand-name organic, direct visits, and homepage links — keep those on the homepage. Read the full guide for the decision framework.
