Meta Tag Analyzer & Open Graph Checker
Enter any page's address to check its title, description and Open Graph tags — and preview how it looks when shared. Or paste the page's HTML source below.
How to check any page's meta tags
Meta tags are the hidden labels in a page's HTML that tell search engines and social platforms what the page is about. Visitors never see them on the page itself — but Google reads the title and description before deciding how the page should appear in search results, and Facebook, X, LinkedIn and WhatsApp read the Open Graph tags before building the preview card that shows when a link is shared. A missing or badly written tag is invisible until it costs you a click.
This tool reads a page's public HTML and lists every tag it checks, with the value it found or the word “Missing” when the tag is not there. It never guesses or fills in values that are not in the page — a missing tag is shown as missing, so you know exactly what to fix.
How to use it (3 steps)
- Type the page address. Enter any public URL — for example, reviewkarts.com. You can leave off the https:// part; the tool adds it. Or paste the page's HTML source into the second box instead.
- Click “Analyze URL” (or “Analyze Pasted HTML”). The tool fetches the page through ReviewKarts' own server-side fetch service and reads the tags from the returned HTML.
- Read the table, the verdicts and the share preview. The table lists the title, meta description, og:title, og:description, og:image, og:type, og:url, twitter:card, twitter:title, twitter:description, twitter:image, canonical, meta robots and viewport — each with its value or “Missing”. The verdicts call out the title and description lengths and whether og:image and twitter:card are present, and the share preview shows the card as a social platform would build it.
Worked example: reviewkarts.com
Take this very site as an example. Typing reviewkarts.com finds the homepage title “ReviewKarts — Free Online Tools & Honest Software Reviews”, a meta description that describes the site's free tools, and an og:image pointing at the ReviewKarts logo — so the share preview shows the logo with the site's title and description. Run the same check on your own pages: if your og:image is missing, your shared links will show no image at all.
What meta tags are
A meta tag is a short instruction that lives inside the <head> section of a page's HTML. The title is the blue link text in a search result, and it is also the text of the browser tab. The meta description is the short paragraph that usually appears under the title in search results — it does not directly change rankings, but a clear description wins more clicks. The canonical tag tells search engines which address is the official one for a page, meta robots tells them whether to index it, and the viewport tag tells phones how wide the page should be.
Open Graph is a set of tags that start with “og:” — og:title, og:description, og:image, og:type and og:url — invented by Facebook and now used by almost every social platform. When someone pastes a link into Facebook, LinkedIn or WhatsApp, the platform reads these tags to build the preview card. Twitter (now X) has its own parallel set — twitter:card, twitter:title, twitter:description and twitter:image.
Why the share preview matters
Most people decide whether to click a shared link from the preview card alone — the image, the title and one or two lines of description. A page with a sharp title, a clear description and a proper og:image gets clicked far more often than the same link shared with no image and a title the platform had to guess. That is why the verdicts focus on the practical checks: is the title between 50 and 60 characters, is the description between 150 and 160, is there an og:image, and is there a twitter:card. A title longer than 60 characters gets cut off in search results, and a description longer than 160 gets the same treatment.
Everything here runs in your browser: the fetch goes through ReviewKarts' own fetch service only to read the page's public HTML, and nothing you type is stored. The same public HTML is what our Website Technology Detector reads when you want to know what a site is built with.
Frequently asked questions
What are meta tags?
Meta tags are small pieces of information in a page's HTML head that describe the page — its title, a short description, and instructions for search engines and social platforms. Visitors do not see them on the page, but search engines and social networks do.
What is Open Graph?
Open Graph is a set of meta tags (starting with og:) that tell Facebook, LinkedIn, WhatsApp and other platforms which title, description and image to show when a link is shared. Twitter (now X) has its own similar tags — twitter:card and the rest.
Why does the share preview matter?
When someone shares your page, most people decide whether to click from the preview card — the title, the description and the image. A missing og:image means the shared link shows no image at all, and a weak title means fewer clicks.
What makes a good title and description?
A title of about 50–60 characters that says what the page is about, and a description of about 150–160 characters that tells the reader what they will get. Longer titles and descriptions get trimmed in search results — the ideal lengths are the ones that fit.
Is this free, and does it store the URL I type?
Yes, it is free, and no — the URL is fetched through ReviewKarts' own fetch service only to read the page's public HTML, and nothing you type is stored. The check itself runs entirely in your browser.
