SERPsim

SERPsim shows you exactly how your title tag and meta description will appear in Google search results, counting pixels instead of characters. Before you publish, you already know if your snippet will be truncated.

SERPsim is a free web tool for simulating and previewing snippets in Google search results. The problem it solves is precise: Google doesn't truncate meta tags based on character count but based on pixel width, which means a 60-character string made of wide letters (like 'W') may be truncated while one of 65 characters made of narrow letters (like 'i') won't be. SERPsim counts pixels as you type and shows in real time a realistic preview of how the snippet will appear in desktop and mobile Google results, signaling when the title or description will exceed display limits. You can choose normal or mobile search mode for their respective previews. It's a simple, free tool used daily by SEO specialists, copywriters and anyone optimizing their site's meta tags.

For SEO specialists, copywriters and content creators who optimize their site's meta tags and want to preview the snippet before publishing to avoid truncation in Google results.

SERPsim is completely free, with no registration and no paid plans. It's a simple, specialized tool accessible to anyone directly from the browser.
