SERP Simulator

SERP Simulator, also called SERPsim, is a free preview tool for title tags and meta descriptions. It shows how Google would cut off a snippet on mobile and desktop before a page is published, with pixel-accurate widths and no signup. Mobile is the default view because the mobile snippet box is narrower, so a description that fits on desktop can clip there. The preview also simulates AI Overviews, ads and People Also Ask panels with placeholder content to show how they push a result down the page. Guidance sections explain how long a title tag and a meta description should be, why Google often rewrites titles anyway, and what a preview cannot show, since real results change with query, location, language and personalization.
