SERP Preview Tool — Google Snippet Simulator

Write a title tag and meta description and see exactly where Google is likely to cut them off — measured in pixels, not just characters, on desktop and mobile.

    Cómo usar: SERP Preview

    1. Type or paste your title tag and meta description. The meters turn green when the text fits Google’s pixel budget.
    2. Add the page URL and an optional site name — the preview builds the breadcrumb (example.com › blog › post) from it.
    3. Enter the search query you are targeting to see which words Google would bold, and toggle the date or review stars to see how much space they take.
    4. Compare the desktop and mobile previews, fix anything marked in Snippet checks, then copy the HTML tags or a share link for your client or team.

    What is a SERP preview?

    A SERP (search engine results page) preview shows how a page is likely to appear as a blue-link result in Google: the favicon and site name, the breadcrumb-style URL, the clickable title and the gray description snippet. It lets you write and polish your <title> and <meta name="description"> before publishing, instead of discovering a cut-off headline in Search Console weeks later.

    Why pixels matter more than characters

    Google truncates titles and descriptions by rendered width, not by a character count. A capital “W” is roughly three times wider than a lowercase “i”, so a 60-character title in uppercase can be cut while a 70-character title full of narrow letters fits. This tool measures your text with the same fonts Google uses (Arial 20 px for desktop titles, 14 px for descriptions) via the browser’s canvas API, and truncates at a word boundary with an ellipsis the way Google does.

    ElementApprox. limitRough character equivalent
    Desktop title~580–600 px50–60 characters
    Desktop description~920 px150–160 characters
    Mobile titletwo linesup to ~75 characters
    Mobile description~680 px~120 characters

    These limits are observations, not published rules — Google adjusts its layout regularly and may rewrite a title or snippet entirely if it thinks other text on the page matches the query better.

    Tips for titles and descriptions that earn clicks

    • Front-load the keyword. Put the topic people search for in the first few words, so it survives truncation and gets noticed when users scan.
    • Keep the brand short and at the end. Google often shows your site name separately above the URL, so “| Brand Name Inc.” at the end of every title mostly costs space.
    • Write descriptions as a promise. Say what the visitor gets — a price, a checklist, a free tool — rather than repeating the title. Google bolds words that match the query, so natural use of the keyword helps the snippet stand out.
    • Remember dates and stars eat space. A visible date (“Oct 25, 2026 —”) is shown in front of the description and reduces how much of your text fits. Review stars only appear for eligible schema types such as Product or Recipe — you can generate the markup with the Schema Markup Generator.

    Using it on a Webflow site

    In Webflow, the title and description live in Page settings › SEO settings. On CMS template pages you can build them from fields (for example Name | Category) — paste a typical item’s values here to check that long CMS names don’t get truncated. To check what a live page actually outputs, run it through the Meta Tag Checker; to write the complete set of head tags, use the Meta Tag Generator.

    Preguntas frecuentes

    How long should a title tag be?
    Aim for roughly 50–60 characters, or more precisely under about 580 pixels on desktop. Keep the most important words at the start so nothing important is lost if Google truncates it.
    How long should a meta description be?
    Around 120–155 characters works on both mobile and desktop. Google’s desktop budget is about 920 pixels, but mobile cuts descriptions earlier, so put the key message in the first 120 characters.
    Why does Google show a different title or description than mine?
    Google rewrites titles and snippets when it thinks they don’t describe the page well, are stuffed with keywords, or don’t match the query. Descriptive, unique titles that match the H1 are rewritten less often.
    Is this preview exactly what Google will show?
    It is a close approximation using Google’s fonts and observed pixel limits. Google’s layout changes over time and differs by device, browser width and result features, so treat the meters as guidance with a small safety margin.
    Can I share the preview with a client?
    Yes. The title, description and URL are stored in the page address, so “Copy share link” gives you a URL that opens the same preview. Nothing is saved on our server.
    ¿Puedo instalar SERP Preview como aplicación web y utilizarla sin conexión?
    Sí. SERP Preview es una aplicación web instalable (PWA): se instala desde el navegador, no se descarga desde una tienda de aplicaciones. Haz clic en «Instalar aplicación» en la parte superior de esta página en Chrome o Edge (Windows, macOS, Linux, ChromeOS) o, en Android, utiliza «Compartir» → «Añadir a la pantalla de inicio» en iPhone y iPad, o «Archivo» → «Añadir al Dock» en Safari 17+ en un Mac. A continuación, se abrirá en su propia ventana con su propio icono y, como se ejecuta íntegramente en tu navegador, seguirá funcionando sin conexión. Firefox en el ordenador de sobremesa no permite instalar aplicaciones web. Cómo funciona la instalación.
