Meta Tag and Canonical Check

The page is genuinely fetched and everything Google and social networks take from its head is extracted and evaluated. If your page link shows in WhatsApp with no image, the answer is here.

  • No sign-up needed
  • Open Graph covered too
  • All the page H1s

Run the tool right here on the page

In one view, line up a page's title tag, meta description, canonical, H1 and share tags.

This tool executes on our own infrastructure with no purchased data behind it, so it costs nothing and stays that way. Its only limit is a daily cap that stops one bot from taking the whole capacity. The daily cap is measured per visitor. If you need more, a free account lifts your limit.

The short answer

Meta tags are the part of a page a visitor never sees but Google, Telegram and WhatsApp read: the title, the description, the canonical, the indexing directive and the sharing image. If the title you see in Google results is not the one you expected, the difference almost always comes from here.

Of these tags the canonical is the one that causes the most trouble, because it does its work without a sound. When a canonical points somewhere other than the page itself, the message to Google is to set this version aside, and Google sets it aside with no error and no notification. The most frequent case is every page taking the front page's canonical, usually following a bad configuration in an SEO plugin or a migration off a staging environment.

The second thing to look at is the number of H1s. The right state is one H1 per page, saying what the page is about. With no H1 at all, Google has to guess; with more than one, the theme has usually coded the logo or the site name as an H1. Neither of these is a disaster, but both carry the same message: nobody who was paying attention laid out the page structure.

The third area is the social preview tags, almost always forgotten while producing the fastest effect. If your link opens in WhatsApp or Telegram with no picture and no summary, it draws far fewer clicks than the same link with a tidy card. For sites in Iran that get much of their traffic from those two messengers, this small change carries a high return.

The data source and method

Our server takes the raw HTML and reads the tags without running JavaScript. This is a genuine limit: if your meta tags are assembled by JavaScript, as on some React and Next sites, they look empty here. Even so, Google reads that same raw HTML on its first pass, so an empty result here is itself a warning rather than merely a tool error.

The situations where it helps

Before an important page goes live, or when a page appears in Google under the wrong title. Also to find out why the page's link opens without an image in WhatsApp or Telegram.

Where it falls short

What gets inspected is the page's initial HTML, with no JavaScript run against it. If your meta tags are assembled in the browser, as on part of the React and Next world, their slots are blank in this output. Do not read that as a tool fault: Google too sees exactly this initial code on its first indexing pass and puts JavaScript execution in a separate, slower slot, so a blank section here is a serious warning in itself. The next limit is that the tool shows the content you declared, not what Google places in results. Google reshapes the title and description for each query, so a correct title here does not mean that title appears in results.

A lesson from working with it

If a link shows in WhatsApp with no picture while the og:image tag is filled correctly, the knot is usually in the image file, not the tag. An image hidden behind a user login, sitting on a relative URL, or unreachable from outside the network is not downloaded and the card is left blank. To test it, open the URL written in og:image in a browser that is not signed in to the site; if you cannot see it yourself, WhatsApp will not either.

Common questions about this tool

Why does Google show a different title from mine?

Google rewrites titles per query, usually when yours runs too long, repeats the keyword, or puts the brand name in front for no reason. A shorter, more descriptive title has a better chance of holding.

Should the canonical point at the page itself?

Normally yes. Self-reference is the correct state for any page that is its own original. Pointing elsewhere is right only when you genuinely are a duplicate of another page, for example a page with a filter parameter.

Does the meta description affect rankings?

Not directly. Its effect is on click-through rate, which is no small thing: two results in the same position with two different descriptions draw different clicks. Write it for a person, not for an algorithm.

This page in the Seemerce family

Title, description and share tags for a page, as the crawler reads them.

One rule throughout: See fuses onto a word and makes a single new one, never two words side by side. Exactly as See and commerce became Seemerce.
