How the SEO score is calculated
Every page receives an overall SEO score from 0 to 100 based on three weighted components. The formula is transparent — there are no hidden factors or paywalled “advanced” checks.
40%
Title tag score
Scores 100 at 30–60 chars, 80 at 61–70 chars, 50 above 70, and 40 below 30.
40%
Description score
Scores 100 at 120–160 chars, 80 at 161–200 chars, 50 above 200, and 40 below 120.
20%
Keyword score
Scores 100 when keyword is in both fields, 90 in title only, 70 in description only, 0 if missing.
Formula: Overall = (Title Score × 0.4) + (Description Score × 0.4) + (Keyword Score × 0.2). A score of 80+ means your meta tags are well-optimized for search engines. Below 50 indicates critical issues that will likely hurt click-through rates.
Frequently asked questions
What is an SEO meta preview?
An SEO meta preview is a visual simulation of how your web page appears in search engine results pages (SERPs). It renders your title tag (optimal: 30–60 characters, max 600 pixels wide) and meta description (optimal: 155–160 characters) exactly as Google or Bing would display them — including pixel-accurate truncation — so you can catch cut-off text before publishing. This tool checks all 4 preview formats (Google desktop, Google mobile, Bing, and Open Graph social cards) simultaneously.
How is the SEO score calculated?
The SEO score uses a weighted formula: title tag (40%), meta description (40%), and keyword placement (20%). Each component scores from 0 to 100 based on character count, pixel width (titles must stay under 600 pixels), keyword presence, and truncation risk. The three scores combine into an overall rating where 80+ indicates well-optimized tags and below 50 flags critical issues.
What search engines are supported?
The tool renders 4 preview formats: Google desktop (600px title container), Google mobile (360px, 50-char title limit), Bing (560px, 65-char title limit), and Open Graph social cards (1200×630px image, 65-char title, 155-char description) as they appear on Facebook, LinkedIn, and Slack. Each preview uses the correct font family, font size, and pixel widths for that specific search engine.
Is this tool free to use?
Yes. SEO Meta Preview & Scorer is completely free to use. There is no account, no paywall, and no usage limit. All analysis runs entirely in your browser — your data never leaves your device.
