Title & description
Audits the <title> and meta description for presence and length so the SERP snippet renders at full width instead of truncating mid-pitch.
SEO & Discovery Checker
Audits on-page SEO meta tags, plus root-level robots.txt and sitemap.xml files. Checks lengths, presence of critical tags (title, description), and search engine indexing readiness.
Instant audit. No account required.
What the SEO & Discovery audit checks
Three checks, one verdict. Each tile is a primitive your AI agent can read alongside the full JSON payload.
Robots & canonicals
Inspects robots.txt and rel=canonical so crawl directives stay coherent and no accidental noindex slips into production.
Sitemap & schema
Confirms sitemap.xml is reachable from the root and surfaces any structured-data hints the page is shipping to Google.

ℹ️
Meta tags are snippets of text that describe a page's content; the meta tags don't appear on the page itself, but only in the page's source code. Meta tags are essentially little content descriptors that help tell search engines what a web page is about.
What Our SEO Meta Checker Validates
Our free analyzer performs a comprehensive audit of your page's metadata:
✅ Title Tag Analysis
Checks your <title> tag for length (ideal: 50-60 characters) and keyword placement. A well-optimized title is critical for both ranking and user clicks.
✅ Meta Description Audit
Validates your meta description for length (ideal: 150-160 characters) and clarity. Although not a direct ranking factor, it is the primary driver of CTR from search results.
✅ Canonical URL Check
Ensures you have a self-referential rel="canonical" tag to prevent duplicate content issues and consolidate ranking authority.
✅ Social Media (Open Graph) Tags
Verifies og:title, og:description, and og:image tags. These ensure your content looks professional when shared on LinkedIn, X (Twitter), and Facebook.
Why SEO Metadata Matters
| Metric | Impact |
|---|---|
| Missing Title | Generic "Untitled" results in Google - 0% click rate. |
| Short Description | Google may auto-generate a poor snippet from your page content. |
| Missing Canonical | Potential SEO penalty for "Duplicate Content" across URL variants. |
| No OG Image | Shared links look like spam or broken pages on social media. |
SEO Meta Best Practices
The "Front-Loading" Rule
Place your most important keywords at the beginning of your Title tag to ensure they are visible even if the title is truncated on smaller screens.
Unique Metadata per Page
Never use the same Title or Meta Description for multiple pages. This confuses search engines and leads to internal competition (keyword cannibalization).
Frequently Asked Questions
Do keywords in meta tags help ranking?
Keywords in the Title tag are a major ranking factor. However, keywords in the Meta Keywords tag are ignored by all modern search engines. Keywords in the Meta Description help with CTR but not direct ranking.
How long should my meta description be?
Aim for 155 characters. If it's longer, Google will truncate it with an ellipsis (...). If it's too short, it might not provide enough context to encourage a click.
What is a Canonical tag?
It's a way of telling search engines: "Even if you found this content on multiple URLs, this is the master version that I want you to index and rank."
