Stateless Tools

SEO Meta Tag Checker

🔒 Browser-side processing

Inspect title, description, OG, and canonical tags from a URL or pasted HTML.

Overview

Use this page to check the baseline SEO signals first

Search performance still depends far more on content quality and search intent, but empty titles, missing descriptions, broken canonicals, and weak sharing tags are baseline problems you should catch immediately. This tool is tuned for that first pass.

Audit core metadata

Check title, description, H1, canonical, and robots together before you spend time on deeper SEO questions.

Review sharing previews

Missing OG title and description tags often hurt link previews even when the page is otherwise fine for search.

Confirm structured-data presence

JSON-LD is not always required, but this page helps you see quickly whether it exists on pages that might benefit from it.

How To

The most practical way to use this checker

1. Use the URL when the page is directly readable

If the page is same-origin or explicitly allows CORS, a direct URL check is the fastest path.

2. Fall back to pasted HTML when fetch is blocked

Many external sites block browser fetches. In that case, paste the raw source into the HTML field instead of fighting CORS.

3. Fix gaps before debating rankings

Missing tags, weak title and description lengths, and accidental noindex directives are easier wins than abstract SEO theory.

Priority Checklist

What to check before a page goes public

SEO is not a one-time score. It is an ongoing fit between search intent and page quality. Still, these are the baseline items worth checking before a new page is published.

Title

Each page should have a unique title that puts the search intent and page purpose near the front.

Description

The description helps users decide whether to click. It should explain the page value clearly and specifically.

Canonical

If duplicate or variant URLs can exist, pick a representative canonical URL to reduce mixed signals.

Robots

An accidental noindex tag can keep an otherwise useful page out of search results.

Open Graph

Search is not the only preview surface. Check how links appear in social, chat, and community posts.

Structured Data

FAQ, HowTo, and WebApplication schema can help search engines understand clearly structured pages.

Search Quality

What matters when search and ads both matter

Tools alone can look thin

The utility matters, but search engines and ad review also need to see that the page explains a real problem well. Examples, FAQs, and related guides help.

Keywords need body support

Putting “JSON formatter” or “UUID generator” in a title is not enough. The body should naturally explain use cases, failure modes, and next steps.

Internal links should reveal the next action

After an SEO check, users often need UTM links, query strings, or API response checks. Good internal links make that path obvious.

FAQ

Questions that come up in practice

Can this tool always fetch an external page?

No. It runs in the browser, so many third-party pages will block direct fetches with CORS. That is why the pasted HTML route is built in.

Does it give a final SEO score?

No. This page is for rapid diagnosis and prioritization. Real SEO still depends on the body content, search intent, internal linking, and trust signals.
