How to Check Link Previews Before Sharing

When someone shares a website link, many apps show a preview with a title, description, and image.

A clear link preview can help people understand the page before they click.

A broken or missing preview can make a useful page look unfinished or less trustworthy.

The preview title should clearly explain what the page is about.

Avoid vague titles such as Home, Tool, or Untitled Page.

For blog posts and tools, include the main topic or benefit in the title.

The preview description should summarize the page in one or two clear sentences.

It should help users decide whether the link is useful for them.

Avoid using the same description on every page because repeated descriptions look low quality.

A good preview image should be relevant to the page and easy to understand at a small size.

Before using an image, resize and compress it so it loads quickly.

Avoid blurry images, empty screenshots, or images with tiny unreadable text.

Open Graph tags help control how a page appears when shared on social platforms and messaging apps.

A checker tool can show whether the page has a title, description, image, and correct URL.

Testing these tags before publishing helps avoid broken previews after people start sharing the page.

If the wrong image appears, check the Open Graph image tag and make sure the image URL is public.

If the title is wrong, update the page title and Open Graph title.

If no preview appears, check whether the page is blocked, private, missing metadata, or returning an error.

What is a link preview? It is the card that appears when a URL is shared in many apps.

What are Open Graph tags? They are metadata tags that help control social sharing previews.

Why is my preview image missing? The image may be too large, blocked, broken, or missing from the page metadata.

Should every important page have a preview? Yes. Blog posts, tools, landing pages, and product pages should have clear previews.
