Link in bio checker

Paste the address of any bio page. See the preview people get when you share it. Then see what Google and AI crawlers read in the HTML.

What a link in bio checker does

A link in bio checker opens one public page the way a crawler does and reports what it finds. It reads the HTML the server sends, without running JavaScript, because many crawlers read pages that way. Then it reads the site's robots.txt and looks for an llms.txt file.

The report has four parts. The share preview is the card a chat app or social post shows for your link. The search part covers the title, the description and any noindex rule. The AI part counts the words in the HTML, lists the structured data types and checks that every link has a name. The crawler part says what robots.txt allows for six named crawlers.

The checker reads the page once to build the report. It does not save the page or the address you paste. It only opens public addresses on the normal web ports.

How to check a bio page

  1. Paste the address

    Use your own bio page, or a page you want to compare. The checker adds https:// when you leave it out.

  2. Look at the share preview

    This is the card people see when you send the link. A missing image or title is the first thing to fix.

  3. Read the checks

    Each line says what the checker found and why it matters. Fix the lines marked Fix first, then the ones marked Check.

  4. Check again after a change

    Change the page in your bio tool, then paste the address again. Chat apps keep old previews for some time, so test a new chat.

Checks and their official sources

Each check follows a public rule. These are the rules, with the official page for each.

Link in bio checker questions

Why does the checker find fewer words than I see in my browser?

The checker reads the HTML that the server sends and does not run JavaScript. Your browser runs JavaScript and adds more content. Many crawlers read pages the same way. A page that builds its text with JavaScript can look almost empty to them.

What is a share preview?

A share preview is the card that appears when you paste a link in a chat, a post or an email. It shows a title, a short description and an image. The site sets them with Open Graph tags: og:title, og:description and og:image. The checker shows the card those tags make.

I changed my share image. Why do chat apps still show the old one?

Chat apps and social sites keep a copy of a preview for some time. A new chat or a new post often shows the change first. Facebook and LinkedIn have their own debugger pages where you can ask them to read the page again.

Why does a link need a name?

A button that shows only an icon has no text in the HTML. People see the icon and know where it goes. A crawler sees a link with no name, so it cannot tell what the link is for. Add a text label or an aria-label to every link.

What does it mean when a crawler is blocked in robots.txt?

The site's robots.txt file asks that crawler not to read this address. Each AI company names its own crawlers, and a site can allow some and block others. The checker reads the rules for six crawlers and shows which ones may read the page.

Do I need an llms.txt file?

llms.txt is a proposed format for a short markdown summary of a site and its main links. Support differs between AI assistants. The file is small and easy to keep current. Any assistant that reads it gets a clear summary.

Does the checker store my page or my address?

No. The checker reads the page, the robots.txt file and any llms.txt file once to build the report. It does not save the page or the address you paste. It only opens public addresses on the normal web ports, and it never signs in.

Why did the check fail?

Some sites block automated visitors or answer slowly, and the checker stops after a few seconds. It also refuses private or local addresses. Check that the address opens in a private browser window, then try again. After 10 checks in one minute, wait a minute. After 60 checks in one hour, try again later.
