How to Set Open Graph Tags for a Tamil Website

Set Open Graph tags in the page’s <head>, using Tamil page content and a locale that reflects the intended audience. For a Tamil page aimed at India, ta_IN is a suitable example; it is not a universal locale for every Tamil website. The core properties are og:title, og:type, og:image, and og:url.

1. Add the tags to the page head

Replace the example URL, title, description, site name, image, and image description with values for the actual page. Keep the ordinary HTML language declaration consistent with the page language.

<!doctype html>
<html lang="ta-IN">
<head>
  <meta charset="utf-8">
  <title>தமிழ் பக்கத் தலைப்பு</title>

  <meta property="og:title" content="தமிழ் பக்கத் தலைப்பு">
  <meta property="og:type" content="website">
  <meta property="og:url" content="https://example.com/ta/page/">
  <meta property="og:image" content="https://example.com/images/tamil-page.jpg">
  <meta property="og:locale" content="ta_IN">
  <meta property="og:description" content="இந்தப் பக்கத்தின் சுருக்கமான தமிழ் விளக்கம்.">
  <meta property="og:site_name" content="உங்கள் தளத்தின் பெயர்">
  <meta property="og:image:alt" content="பகிரப்படும் படத்தின் சுருக்கமான விளக்கம்">
</head>
<body>
  <!-- page content -->
</body>
</html>

The example uses Tamil text to show where localized content belongs. Supply accurate Tamil text for your page; do not copy placeholder content into production.

2. Choose the right locale and page values

Property	Purpose	What to set
og:title	Share title	A concise, page-specific title in Tamil when that is the page’s language.
og:type	Describes the object	Use website for an ordinary website page. Choose a more specific supported type only when it accurately describes the object.
og:image	Representative share image	An absolute URL to an image that the sharing platform can fetch.
og:url	Canonical page identity	The canonical URL for this page, not a different language version or unrelated landing page.
og:locale	Language and territory	A value in language_TERRITORY form, such as ta_IN for a Tamil page aimed at India.
og:description	Share summary	A useful one- or two-sentence summary of this specific page.
og:site_name	Identifies the overall site	The site name when the page belongs to a named site.
og:image:alt	Image alternative description	A concise description of what the image depicts. It is not a caption.

The protocol documents en_US as its default locale. Set the locale explicitly for Tamil content instead of relying on that default. Tamil identifies a language, not a territory: select the territory for the intended audience. If the same page has language alternatives, provide their locale values with og:locale:alternate.

Open Graph also defines optional image metadata: og:image:secure_url, og:image:type, og:image:width, and og:image:height. Add these when their values are known and useful to consumers; do not guess them. This guide does not prescribe platform-specific image limits.

3. Choose how your site emits metadata

For a static page or custom application, put the tags directly in the HTML template or server-rendered document head. For a CMS, its theme or SEO layer may generate them. Yoast documents generated Open Graph output in its functional specification, but a plugin is not required by the protocol.

Whichever approach you use, inspect the HTML delivered to a crawler. Metadata injected only after client-side JavaScript runs may not appear in the initial response a parser reads. Ensure each page emits its own title, description, canonical URL, locale, and image rather than reusing one site-wide set.

4. Validate the rendered page and share preview

1. Open the page’s delivered HTML source and confirm the Open Graph tags are inside <head>.
2. Check that the title and description match the Tamil page, and that lang, og:locale, and the page’s actual language and intended audience agree.
3. Confirm og:url is the canonical URL for this exact page and that og:image is an absolute URL to the intended, fetchable image.
4. Include og:image:alt and ensure it describes the image rather than repeating the page title.
5. Use the target social platform’s current preview or debugging tool to inspect what it reads. After changing metadata, fetch the page again there. Platform tools and caching behavior can change, so verify with the platform you intend to use.

To inspect the delivered HTML without setting up a browser, ScreenshotNeo can capture a page through a single API request. The screenshot is a visual check; still inspect the HTML source or page metadata separately to confirm the tag values.

5. Common problems and fixes

Symptom	Likely cause	Fix
The preview shows a default or wrong-language title.	The page is inheriting site-wide metadata, or the Tamil page’s tags are missing from delivered HTML.	Emit page-specific tags in the document head and inspect the actual response source.
The locale reads as English or is absent.	The default locale is being used or no explicit locale was generated.	Set an audience-appropriate value such as ta_IN for a Tamil page aimed at India.
The preview links to the wrong page.	og:url points to another route, language version, or noncanonical URL.	Set it to the canonical URL for the page being shared.
The share image is missing.	The image URL is relative, incorrect, or unavailable to the platform fetcher.	Use an absolute URL and verify that the intended image can be fetched.
The preview does not reflect a recent edit.	The platform may be showing a previously fetched preview.	Use the platform’s current preview/debugging tool to request a fresh fetch; confirm the current tool’s behavior.
Tags appear in the browser but not to the sharing parser.	The tags may be added only after client-side rendering, or the delivered source differs from the browser’s final DOM.	Render the tags into the initial HTML response and check the source sent to crawlers.

6. Performance, reliability, and cost

Open Graph tags are metadata in the document head; this implementation does not require a paid plugin or screenshot service. The practical reliability concern is whether the intended parser can fetch the page and image and whether the metadata is present in the HTML it receives. Keep the values page-specific and verify the response after template or CMS changes.

For a visual inspection of a page while debugging, a screenshot service can show what rendered, but it does not replace checking the HTML metadata. ScreenshotNeo provides a website screenshot API and MCP server. Its clean-shot flow accepts consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each step can be turned off. Only clean shots are billed: bot checks, CAPTCHAs, blank pages, timeouts, failed loads, and cache hits cost nothing, with the response indicating the page verdict and billing status. Plans include 1,000 shots per month free without a card; paid plans start at $5 for 3,000 shots. See [ScreenshotNeo](https://screenshotneo.com).

7. Or skip the browser setup

Use ScreenshotNeo when you need a rendered-page screenshot for a visual check. The API returns an image or PDF from one GET request. See the [ScreenshotNeo API documentation](https://screenshotneo.com/docs/) for options.

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.com/ta/page/ -o shot.webp

import requests

r = requests.get(
    "https://api.screenshotneo.com/v1/shot",
    params={"access_key": "YOUR_API_KEY", "url": "https://example.com/ta/page/"},
    timeout=90,
)
open("shot.webp", "wb").write(r.content)

const q = new URLSearchParams({
  access_key: 'YOUR_API_KEY',
  url: 'https://example.com/ta/page/'
});
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);
if (!res.ok) throw new Error(`Screenshot request failed: ${res.status}`);
const fs = await import('node:fs/promises');
await fs.writeFile('shot.webp', Buffer.from(await res.arrayBuffer()));

Cookie banners, popups, and chat widgets are removed before the shot. Bot checks, blank pages, and failed loads are never billed. An MCP server lets AI agents take screenshots. The free plan includes 1,000 screenshots a month with no card; paid plans start at $5 for 3,000. [Create a free account](https://screenshotneo.com/account/sign-up/).

8. FAQ

Should every Tamil page use ta_IN?

No. Use it when India is the intended territory. Choose the territory that matches the audience for the page.

Do Open Graph tags replace the HTML lang attribute?

No. Set the document language on the HTML element and set the Open Graph locale in the metadata; keep them consistent.

Is og:image:alt the same as a caption?

No. It is a short alternative description of the share image.

Does a screenshot confirm that the tags are correct?

No. A screenshot helps inspect rendering. Check the delivered HTML and the target platform’s preview tool for metadata behavior.
