What SERP Preview Tool does, with a checked example

You enter a page's title tag, URL, and meta description, and the tool renders them as a Google desktop result: blue title link, green breadcrumb URL, gray snippet, with text cut by an ellipsis wherever Google's display limits bite. Truncation is measured in rendered width, not characters, so the preview shows where a title or description will actually cut. The surprise most people bring: since Google moved to pixel-based truncation, the 70-character rule is dead. The preview shows what would render from your exact text, not what Google will show.

Worked example

A concrete input and expected output from the current implementation.

Input

Title: Complete Guide to Technical SEO Audits for Large E-commerce Websites in 2026
URL: https://example.com/seo-audit-guide
Description: Learn how to run a full technical SEO audit: crawl diagnostics, Core Web Vitals, index coverage, internal linking, prioritization, and reporting. Includes checklists and a prioritized action plan for e-commerce teams.

Expected output

The listing renders with the blue title cut by an ellipsis: 76 characters of mixed-case text, including capitals and wide letters such as W and m, measure wider than the roughly 600px desktop title limit, so the tail of the title is replaced with an ellipsis. The green URL line shows example.com/seo-audit-guide with the protocol stripped. The 217-character description wraps onto a second line and is cut with an ellipsis at the column edge.

The 76-character title, with its capitals and wide glyphs, renders wider than the about-600px limit at the type size Google uses for desktop results, so the preview cuts it with an ellipsis. The 217-character description exceeds what two lines of the result column can hold, so it cuts with an ellipsis as well. Both counts are the literal text lengths of the inputs.

How the result is produced

1

What you enter

You paste the page's title tag, URL, and meta description, and the tool renders a single search-result listing: the title as a blue clickable link, the URL as a green breadcrumb, the description as a gray snippet, laid out with the type sizes and spacing Google uses on desktop. No query is involved; it simulates display only, not ranking, position, or click behavior.

Pixels, not characters

The tool measures the rendered width of each text element and cuts it with an ellipsis at the limit. Desktop titles are held to roughly 600 pixels, descriptions to two lines. Wide glyphs such as W, m, and capitals consume more width than narrow ones such as i and l, so two titles with identical character counts can truncate at different points, and mobile results use tighter limits.

Good uses

  • Before publishing a page, confirm that the title and meta description you wrote render completely, keeping the primary keyword and brand name visible instead of ending in an ellipsis.
  • When a page's click-through rate drops, run its live title and description through the preview to check whether truncation is hiding the wording that tells searchers what the page is about.
  • Compare candidate titles side by side, with and without a brand suffix or date, to pick the version that keeps the selling point inside the width limit before you commit it to the page.

Limits and checks

  • A clean preview is not a guarantee of a clean listing. Google often rewrites titles to fit the query and shows descriptions pulled from page content instead of your meta description, so the rendered text can differ from what you typed.
  • The truncation limits are community measurements, not published Google specifications; Google has never documented exact pixel widths. The roughly 600px desktop figure has held since early 2022, but a future interface change can shift where text cuts.
  • The preview models appearance only, with no query context, position, or competition, so a perfectly rendered title can still underperform, and truncation is not the cause of every low click-through rate. It reflects desktop rendering; mobile cuts earlier, so check the device your audience uses.

Common questions

My title is under 70 characters, so why does the preview cut it off?

Google stopped truncating titles by character count in January 2022 and now cuts them by measured width, about 600px on desktop. A 70-character title heavy in capitals or wide letters such as W and m can exceed that width and display with an ellipsis, while a lowercase narrow title of the same length can fit. Width decides, not count.

If the preview looks good, will Google show my title and description exactly like that?

Not necessarily. The preview renders the exact text you entered, but Google can rewrite the title to match the query and display a description pulled from page content instead of your meta description. It also caches what it shows, so after you publish or edit a tag, expect a delay, often several days, before Google re-crawls and re-renders the result.
