You place meta elements in the document’s <head>; social networks, messaging apps, search features, and other crawlers can then use those values to build a link preview. Open Graph does not change the visible page itself, and it cannot force every service to render an identical preview.
How Open Graph works
The Open Graph protocol was designed to let a webpage become a rich object in a social graph. A page publishes machine-readable properties such as its title, type, canonical identity, and representative image. A consumer fetches the HTML, reads the properties it supports, and decides how to display the shared link.
That separation matters: your page can have one visible headline and a different social title, while a platform may ignore a field, cache an older value, or apply its own image and text rules. Accurate tags improve the information available to consumers, but they are not a guarantee of a particular card design.
The four required Open Graph properties
The protocol defines four basic properties for every page.

| Property | Purpose | Typical value |
|---|---|---|
og:title |
The title of the object as it should appear in the graph. | A Page Title |
og:type |
The kind of object being described. | website, or another supported type that accurately fits the page |
og:image |
The URL of an image representing the object. | https://example.com/page-preview.jpg |
og:url |
The canonical URL and permanent graph identity for the object. | https://example.com/page/ |
If no type is marked up, the specification treats the page as website. Choose a more specific supported type only when it genuinely describes the object, because some types have additional required properties.
Where to put the tags
Add Open Graph elements inside the HTML document’s <head>, not in the visible body. The property attribute identifies an OG field and content holds its value. A minimal implementation is:
<head prefix="og: https://ogp.me/ns#">
<meta property="og:title" content="A Page Title">
<meta property="og:type" content="website">
<meta property="og:url" content="https://example.com/page/">
<meta property="og:image" content="https://example.com/page-preview.jpg">
<meta property="og:description" content="A concise description of this page.">
</head>The namespace declaration in the example identifies the OG vocabulary. Keep the canonical URL consistent with the URL you want shared and indexed; avoid using a tracking URL, a temporary redirect destination, or a noncanonical duplicate.
Useful optional properties
Description and site identity
og:description supplies a concise, usually one- or two-sentence explanation. og:site_name identifies the broader site, while og:locale describes the page’s language and territory, such as en_US. Use og:locale:alternate when the page has explicitly supported alternate locales.

Image metadata
The protocol supports og:image:secure_url, og:image:type, og:image:width, og:image:height, and og:image:alt. The image URL should be publicly retrievable. The alt value should describe the image itself rather than repeat a marketing caption; the specification says a page specifying og:image should also specify og:image:alt.
<meta property="og:image" content="https://example.com/page-preview.jpg">
<meta property="og:image:secure_url" content="https://example.com/page-preview.jpg">
<meta property="og:image:type" content="image/jpeg">
<meta property="og:image:width" content="1200">
<meta property="og:image:height" content="630">
<meta property="og:image:alt" content="Illustration of the page topic">Multiple images and precedence
You can provide multiple values for properties such as images by repeating the property. When values conflict, consumers generally prefer the first tag encountered from top to bottom. Put your preferred image first and keep the order intentional.
Open Graph versus visible titles and Twitter cards
Open Graph values are metadata; they are separate from the visible <title>, headline, and body copy. You may deliberately tailor the social title or description, but keeping them truthful and recognizable prevents confusing previews.
Twitter-specific card metadata is a different system. Open Graph uses property attributes, whereas guidance for Twitter cards uses separate name-attribute tags such as twitter:card. A platform can combine, override, or ignore fields according to its own crawler and rendering rules.

| Approach | Control | Workflow | Common risk |
|---|---|---|---|
| Direct HTML or template code | Field-level control over every value and fallback. | Managed in the development and deployment process. | Duplicate tags or incorrect values if several templates emit metadata. |
| CMS or SEO plugin | Interface-driven fields, defaults, and fallbacks. | Editors configure social values without editing templates. | Unexpected precedence between social fields, SEO fields, featured images, and theme output. |
A plugin is not required. In a CMS, inspect which component actually generates the final head and establish one source of truth for title, URL, description, and image. Yoast’s documented workflow, for example, can select values from configured social fields, SEO fields, featured images, or fallbacks; the exact precedence depends on its settings.
How to implement Open Graph step by step
- Choose the canonical object. Decide the permanent URL for the page, including the preferred protocol, host, path, and trailing-slash convention.
- Select an accurate type. Use
websitewhen the page is a general site object; use another supported type only when its definition fits. - Write the four required tags. Add one each for title, type, image, and canonical URL in the document head.
- Add context. Include a concise description, site name, locale, and image dimensions, MIME type, secure URL, and alt text when available.
- Render and inspect the delivered HTML. View the page source or fetched response, not only an editor preview. Confirm that tags are present in the initial HTML and that values are not empty or escaped incorrectly.
- Validate the destination. Share the URL through the specific service you care about or use that service’s current preview/debugging tool. Re-crawl or clear a platform cache when its documented workflow requires it.
Troubleshooting common preview problems
The preview uses the wrong title or image
- Look for duplicate OG tags emitted by a theme, plugin, or component. Remove conflicts and place the preferred image first.
- Check that the crawler receives the updated HTML and that the image URL returns the intended file without authentication.
- Remember that consumers cache previews. A correct change may not appear until the destination re-fetches the page.
No preview appears
- Verify that the four required properties exist in the fetched head.
- Confirm that
og:urlresolves and that the page and image are reachable by the consumer’s crawler. - Check redirects, robots or access controls, TLS errors, and server responses that differ between browsers and automated clients.
The image is blank or cropped unexpectedly
- Confirm the URL points directly to an image with the correct MIME type and a stable response.
- Supply width, height, and alt metadata, then test the destination’s current image rules. Open Graph itself does not impose one universal display size.
A single-page app has tags in source but the crawler misses them
If metadata is inserted only after client-side JavaScript runs, a crawler that reads the initial response may not see it. Render OG tags in server output, static HTML, or a pre-rendered route, and inspect the raw response to verify.
Checking pages at scale
For a small site, source inspection and a destination preview tool are usually sufficient. For many URLs, add automated checks for one canonical og:url, one preferred image, nonempty title and description, absolute HTTPS URLs, and duplicate properties. Treat these checks as linting: they confirm what your server emits, while each consumer still controls final presentation.
Or skip the browser setup
If you need a rendered screenshot of an OG preview or any webpage while testing your implementation, ScreenshotNeo provides a website screenshot API and MCP server. It accepts consent banners before capture and removes more than 60 known consent platforms, newsletter popups, and chat widgets; each step can be disabled. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and the response identifies the page verdict and billing status in headers.
One GET request returns PNG, JPEG, WebP, or PDF. The API supports full-page and element captures, device and viewport settings, dark mode, retina scale, custom CSS and JavaScript, selector waits, network-idle waits, request blocking, cookies and headers, geolocation, caching, signed links, asynchronous webhooks, bulk capture, and more. Its MCP server exposes take_screenshot, get_page_info, and capture_pdf for Claude, Cursor, and other MCP clients.

Frequently Asked Questions
Do Open Graph tags improve search rankings directly?
They describe shared-link objects; they are not presented as a direct search-ranking signal in the protocol guidance. Their practical value is giving consuming services better information for previews.
Can one page have more than one og:image?
Yes. Repeat the image properties for multiple candidates, placing the preferred image first because consumers generally give the first value precedence.
