All SEO Tools

What's included

  • Meta Tag Generator — Generate full meta tag blocks including primary (title, description), Open Graph (Facebook, LinkedIn, WhatsApp), and Twitter Card metadata. Live character counts flag overly long titles and descriptions that Google will truncate.
  • Schema Markup Generator — Build valid JSON-LD structured data for Article, Product, FAQ, HowTo, Organization, and LocalBusiness types. Output validates against schema.org and is recognized by Google for rich snippets.

Meta tag best practices (2026)

  • Title tags should be 50–60 characters. Google typically displays the first ~580 pixels, which roughly equals 60 characters in most fonts. Longer titles get truncated with an ellipsis and hurt click-through rate.
  • Meta descriptions should be 150–160 characters for desktop and 120 for mobile. Unlike titles, Google often rewrites descriptions in search results, but a well-written one still increases the odds that your version is shown.
  • Open Graph images should be 1200 × 630 pixels (1.91:1 aspect ratio) with text large enough to read at 600px wide — that's how they display in most social feeds.
  • Twitter Cards now use Open Graph as the default fallback, but twitter:card and twitter:image still improve rendering on X/Twitter.

JSON-LD vs microdata vs RDFa

Google explicitly recommends JSON-LD as the preferred format for structured data since 2015. It's cleaner (data lives in a single <script> block in the head), easier to maintain, and doesn't clutter your HTML. Our Schema Markup Generator outputs JSON-LD exclusively.

When structured data actually earns rich snippets

Adding schema markup does not guarantee rich snippets. Google awards them based on page quality, user intent match, and manual review for certain types (like Recipe or Review). What schema does guarantee is that Google can parse your content unambiguously — which improves ranking signals even when no visible snippet appears.

Validate before shipping

After generating schema markup, validate it with Google's Rich Results Test (search.google.com/test/rich-results) and the Schema.org validator (validator.schema.org). Both are free and catch common errors like missing required properties.
