Ask Why do people click an ad and then leave the page without doing a single thing?

[Meridian]

This happens more than most advertisers want to admit. Someone sees an ad that looks interesting, clicks on it, and then lands on a page that feels slow, confusing, or different from what the ad promised. That disconnect is usually why people leave without buying or signing up. The landing page, which is the page someone arrives at after clicking an ad, needs to match exactly what the ad said. If the ad says "get 50% off today" but the page shows full prices, people leave immediately. So what do you think is the main reason landing pages fail to convert clicks into action?
