Frequently Asked Questions

What are meta tags and why do they matter for SEO?
Meta tags are HTML elements that provide search engines with information about your page. The title tag and meta description appear in search results and directly affect click-through rates. Open Graph and Twitter Card tags control how your page looks when shared on social media.
What is an Open Graph tag?
Open Graph tags (og:title, og:description, og:image) control how your page appears when shared on Facebook, LinkedIn, Slack, and other platforms. Without them, these platforms guess what to display — often with poor results.
How is the SEO grade calculated?
The grade is based on the presence and quality of essential SEO elements: title tag length, meta description length, Open Graph completeness, Twitter Card tags, heading structure (H1/H2), image alt text, canonical URL, and robots directives. Each element is weighted by its SEO impact.
What is a canonical URL and do I need one?
A canonical URL tells search engines which version of a page is the "official" one. This prevents duplicate content issues when the same page is accessible at multiple URLs (e.g. with and without trailing slashes, or with query parameters). Every page should have one.
Is this tool free to use?
Yes, completely free with no limits. For full-site SEO audits that scan every page automatically, check out ModusOp — it includes AI-powered fixes for meta tags, alt text, and more.

Frequently Asked Questions

Is Meta Tag Checker really free?

Yes — completely free, no signup, no credit card, no rate limits, no "premium" tier with the real features locked behind a paywall. We run it because we use it ourselves when auditing client sites. Ads on the page help cover hosting, but the tool itself will always be free to use.

Does it store my URL or scan results?

No. Every check is processed in real time — we fetch the page, parse it, generate your report, and then forget about it. Nothing is written to a database, no tracking beyond standard anonymous Google Analytics, and no emails are captured. See our privacy policy for the full details.

Why do I need a meta description if Google rewrites it anyway?

Google does sometimes rewrite meta descriptions to match the user's search query, but it still uses your written description as a starting point — especially for branded searches and long-tail queries. A well-crafted meta description also controls how your page appears when shared on Slack, Facebook, and LinkedIn previews, so it's worth getting right.

What's the ideal title tag length?

Aim for 30 to 60 characters. Shorter than 30 and you're not giving Google enough signal about what the page is about. Longer than 60 and the title gets truncated in search results, which looks unprofessional and can hurt click-through rates. Meta Tag Checker grades your title against this range and flags anything outside it.

Do I need both Open Graph tags and Twitter Cards?

Ideally yes — they're used by different platforms. Open Graph is the standard that Facebook, LinkedIn, Slack, Discord, and most chat apps use. Twitter Cards are specific to X (Twitter). That said, Twitter falls back to Open Graph tags when Twitter Cards are missing, so if you only implement one, Open Graph gives you wider coverage.

How often should I check my meta tags?

Run a check whenever you publish or significantly update a page — it's a 10-second sanity check that catches the most common SEO mistakes before they go live. For existing sites, we recommend a full audit every three to six months, or whenever you make layout or CMS changes.
