SERP Simulator

SERP Simulator is a browser-based tool that lets you preview how your web page will appear in Google search results (SERP: Search Engine Results Page) on both desktop and smartphone in real time. Simply enter your page title (title tag), URL, and meta description to see an accurate simulation.

Google truncates titles at approximately 600 pixels (about 32 CJK characters or 60 Latin characters) on desktop and approximately 560 pixels (about 28 CJK characters) on mobile. Descriptions are truncated at about 120 CJK characters (160 Latin) on PC and 60 CJK characters (80 Latin) on smartphone. When truncation occurs, critical information in your carefully crafted title or description may be hidden from searchers, leading to lower click-through rates (CTR).

This tool calculates character count and estimated pixel width for both title and description in real time, displaying intuitive color-coded badges: good (green), warning (yellow), and error (red). Each input field shows recommended character counts, and copy buttons let you quickly copy optimized text. You can toggle between PC and smartphone preview tabs to instantly compare how your listing appears on different devices.

SEO specialists, web marketers, bloggers, and content writers can use this tool as a final check before publishing to optimize not just search rankings but also click-through rates. All processing is done entirely in the browser — no input data is ever sent to any server.
