Comprehensive SEO Meta Tag Guide

What is a Title Tag?

The title element defines the title of a webpage in search engine result pages (SERPs) and browser tabs. Recommended title length is between 50 to 60 characters (or ~580 pixels) to avoid truncation.

What is a Meta Description?

The meta description provides a summary of the page content. Aim for 150 to 160 characters. While not a direct ranking factor, compelling descriptions increase organic click-through rates (CTR).

Why are Open Graph (OG) Tags Important?

Open Graph tags (og:title, og:image, og:description) control how your URLs render when shared across Facebook, LinkedIn, Discord, and messaging apps.

How Canonical Tags Prevent Duplicate Content

A canonical URL (rel="canonical") tells search engines which version of a URL represents the master copy, preventing search penalty issues from duplicate parameter URLs.

Frequently Asked Questions

Does this tool use third-party paid SEO APIs?

No. The analyzer performs direct HTTP request fetching and HTML DOM parsing using PHP cURL and DOMDocument, running entirely on your own server.

Is this SEO Diagnostic Score official from Google?

No. The 0–100 score is a diagnostic metric calculated directly against best-practice standards (title presence, canonical consistency, HTTPS, image ALT text, and open graph completeness).
