How to use it
Fill in the page details
Page title, meta description and canonical URL are the three that always matter.
Add the share image
Share image URL has to be absolute. 1200 by 630 pixels works on every platform that reads it.
Set the type and the card
Content type, Twitter card and locale complete the Open Graph and Twitter blocks.
Copy the tags
Copy tags gives the whole set, ready to paste into the head of the page it describes.
The tags that matter
Three do most of the work:
<title>Page title, under about 60 characters</title>
<meta name="description" content="140-160 characters, written for a human." />
<link rel="canonical" href="https://example.com/page" />Then Open Graph, which controls how the link renders when shared:
<meta property="og:type" content="website" />
<meta property="og:title" content="Page title" />
<meta property="og:description" content="Description" />
<meta property="og:url" content="https://example.com/page" />
<meta property="og:image" content="https://example.com/og.png" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />Length targets
| Tag | Target | Truncated at |
|---|---|---|
| Title | 50-60 chars | ~580px desktop, ~920px mobile |
| Description | 140-160 chars | ~920px desktop, ~680px mobile |
| og:title | up to 88 chars | varies by platform |
| og:description | up to 200 chars | ~300 on Facebook |
Because truncation is by pixel width, the character counts are approximations. A title in wide capitals will cut sooner than the same length in lowercase. Front-load the words that matter.
The share image
1200 × 630 is the size that works everywhere. It satisfies the 1.91:1 ratio Facebook and LinkedIn prefer and is large enough for X’s summary_large_image card.
Three requirements that catch people out:
Absolute URL. A relative og:image path fails on every platform. It must include the scheme and host.
Publicly reachable. No authentication, no robots.txt block on the image path, no hotlink protection. Crawlers fetch it as an anonymous client.
Declared dimensions. og:image:width and og:image:height let the platform reserve layout space before the image downloads. Without them, some platforms skip rendering the image on the first fetch.
Keep text in the image large. Previews render small, and a headline that reads fine at full size is often illegible in a feed.
Tags that no longer do anything
meta keywords has been ignored by Google since 2009. It has no effect and mildly signals an out-of-date approach.
meta author, meta revisit-after, meta rating are not used by any major search engine.
FAQ and HowTo structured data no longer produce rich results. HowTo was deprecated in 2023, and FAQ was restricted to authoritative government and health sites before being removed entirely. The markup remains valid and is still parsed. It simply earns no SERP real estate, so do not build a strategy around it.
Getting a preview to refresh
Platforms cache aggressively. When you fix a tag and the old preview persists:
- Facebook and Instagram: Sharing Debugger, then “Scrape Again”
- LinkedIn: Post Inspector
- X: the Card Validator is retired; posting to a private account is the practical test
- WhatsApp: uses Facebook’s cache, so the Sharing Debugger clears it too
Appending a cache-busting query string to the image URL also works, at the cost of a slightly untidy URL.
Common questions
How long should a title tag be?
Around 60 characters. Google truncates by pixel width rather than character count, so the real limit is about 580px on desktop, so a title of capital letters and wide characters truncates sooner than one of narrow lowercase. Put the important words first, because the end is what gets cut.
Does the meta description affect rankings?
Not directly, and Google has confirmed this. It affects click-through rate, which matters commercially. Google also rewrites descriptions for the majority of results, often pulling a more query-relevant snippet from the page, so treat yours as the version you control rather than the version that will always show.
Why is my link preview not showing an image?
Usually one of four things. The og:image URL is relative rather than absolute; the image is behind authentication or a robots block; the file is too large, so keep it under about 5 MB and ideally under 1 MB; or the platform has cached an older version. Facebook's Sharing Debugger and LinkedIn's Post Inspector both let you force a re-fetch.
Do I still need Twitter card tags?
Only for the card type. X falls back to Open Graph for the title, description and image, so `twitter:card` is the one tag that genuinely adds something. Duplicating the rest is harmless and mildly wasteful.
