Pixel-Accurate SERP Preview Tools for Google (URL, Metadata & Combined)

#seo #webdev #tools #performance

Getting Google titles and meta descriptions right is harder than it looks.

Character limits are misleading — Google truncates by pixel width, not characters.

So I built three SERP Preview tools that replicate Google’s behavior with pixel-accurate truncation, real-time previews, and desktop/mobile modes.

🔍 The Three SERP Preview Tools

1️⃣ SERP Preview (Combined Tool)

🔗 https://www.frontendtools.tech/tools/serp-preview

  • Switch between From URL and Metadata modes
  • Default mode: Metadata
  • Ideal if you want both workflows in one place

2️⃣ SERP Preview from URL

🔗 https://www.frontendtools.tech/tools/serp-preview-from-url

  • Fetch title & meta description from any live URL
  • Auto-extracts from HTML
  • Editable after fetch
  • Great for:
    • Competitor analysis
    • Auditing existing pages
    • Verifying published content

3️⃣ SERP Preview from Metadata

🔗 https://www.frontendtools.tech/tools/serp-preview-from-meta

  • Manual input only (no fetching)
  • Designed for pre-publish optimization
  • Ideal for:
    • Writing new content
    • A/B testing titles & descriptions
    • Fine-tuning SEO before launch

✨ Core Features (All Tools)

Pixel-Accurate Truncation

  • Uses Canvas API to measure text width
  • Matches Google’s truncation behavior
  • Font: Arial (same as Google)

Limits

  • Desktop:
    • Title: 600px
    • Description: 920px
    • URL: 600px
  • Mobile:
    • Title: 540px
    • Description: 680px
    • URL: 400px

Real-Time SERP Preview

  • Live updates while typing
  • Desktop & mobile toggle
  • Google-style SERP layout

Visual Optimization Indicators

  • 🟢 Green → Optimal
  • 🟠 Orange → Warning
  • 🔴 Red → Truncated

Includes:

  • Character count
  • Pixel width counter
  • URL truncation matching Google behavior

Copy & Workflow Features

  • One-click copy for title & description
  • Full URL visible on hover
  • Clear loading & error states
  • Progress indicators for fetch operations

🛠 Technical Implementation

  • Next.js 15 + React
  • TypeScript for type safety
  • pdf-lib not used here — instead:
    • Canvas API for pixel measurement
    • Server-side API route to fetch HTML safely
  • Tailwind CSS for responsive UI
  • Framer Motion for smooth transitions
  • Lazy-loaded components for performance

All tools run entirely client-side — no tracking, no storage, no third-party APIs.

🎯 Use Cases

  • Optimize meta tags before publishing
  • Audit existing pages
  • Compare competitor SERPs
  • Improve CTR from Google Search
  • Avoid title & description truncation
