Character count or pixel width — which is right?

Pixel width is right. The same 30 characters can or cannot fit depending on font widths; the tool mimics actual Roboto / Pretendard rendering.

Why does Google ignore my description?

Google replaces the meta description when it is off-topic, keyword-stuffed, or when the body matches the query better. Fix: match the description tone and keywords to the intro paragraph.

Why does Naver show a different description?

Naver synthesizes the description from the first paragraph + H1/H2 plus meta tags. If the meta is too short (<80 chars) or off-topic, Naver pulls from the body instead.

Should I append the site name to the title?

Recommended. Google recognizes " | Site" or " — Site" suffixes and uses them for brand recall and CTR. Just verify the suffix is not the part being truncated.

Will using this tool affect my search ranking?

No. The tool only simulates the rendering — no signal is sent to any search engine. The optional URL fetch is discarded immediately.

About this tool

SERP Snippet Preview is a free SEO tool that simulates how your title, meta description, and URL render across Google desktop, Google mobile, Naver, and Daum search results. It warns by pixel width (the actual cut-off engine uses) — ~600px Google desktop, ~580px mobile, ~480px Naver / Daum — and uses a Roboto / Pretendard width-mimicking function so mixed Korean/English text is judged correctly. Mobile-first since 2024 — mobile preview is foreground. Includes canonical-match check and cross-links with the OG card preview (ogcheck). Everything runs in your browser.

Use cases

Scenario 1

Pre-publish title check

Verify a new blog title fits within mobile (≈28 chars) and follows the recommended " — Site Name" suffix pattern.

Scenario 2

When Google overrides the description

For a page where Google replaces the meta description with the first paragraph, rewrite the description to match the intro tone and keywords, then re-preview.

Scenario 3

Naver universal-search appearance

Check Naver SERP title/description against the ~480px cutoff and avoid being so short that Naver auto-extracts replacement copy.

Scenario 4

Mobile vs desktop side-by-side

Lock a mobile-safe title first (mobile-first indexing), then check whether the desktop extra space can carry an additional descriptor.

Scenario 5

Canonical + OG-card combined check

Validate canonical alongside the SERP snippet, then cross-check Kakao/X/Facebook previews with ogcheck so SNS shares never break.
