Tool guide / Website metadata

Prepare a page for search and sharing

Start with a public page that works at its final URL. Metadata describes that page; search engines and sharing apps decide how to display it. These tools generate files locally, so you can review the result before adding it to your site.

1. Describe the page

Open the Meta Tag Generator. Write a clear title, a short description, and the full canonical URL you want visitors to use. Choose the indexing rule you need. Leave Default selected for an ordinary public page, or choose No index for a page you do not want in search results.

Enable social sharing to include Open Graph and Twitter card tags. Add a public image URL and a description of the image. Copy or download the result and place it inside the page’s HTML <head>. Update existing tags instead of leaving conflicting copies.

<title>My project</title>
<meta name="description" content="A short description of what my project does.">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="canonical" href="https://example.com/">
<meta property="og:title" content="My project">
<meta property="og:type" content="website">
<meta property="og:description" content="A short description of what my project does.">
<meta property="og:url" content="https://example.com/">
<meta property="og:site_name" content="My project">
<meta name="twitter:card" content="summary">
<meta name="twitter:title" content="My project">
<meta name="twitter:description" content="A short description of what my project does.">

Use Open Graph Preview to inspect a sample card and generate sharing tags independently. Each app has its own layout and may cache old metadata. A local preview does not check whether the published image is reachable. Entering an image URL loads that image from its host.

2. Add structured data when it fits

The JSON-LD Generator creates a basic starting point for a website, organization, person, product, or article. Choose HTML snippet to place it in your page, or JSON to use it in your own system. Describe the visible page accurately. Product and article features can require more fields than this starter includes; review the structured data documentation and validate your published page.

3. List public pages and crawler rules

Paste your final page URLs into the Sitemap Generator, one per line. Use the same protocol and host, omit fragments such as #section, and list pages you want indexed. Duplicate URLs are included once. Download sitemap.xml and publish it at your site’s root.

In the robots.txt Generator, use * for all crawlers or enter crawler names one per line. Add Allow and Disallow paths, then add the full URL of your published sitemap. Download robots.txt and publish it at the root too. All agents entered in this tool use the same group of rules.

Crawler rules and No index do not protect private information. Use access controls for private pages. Disallow can also prevent a crawler from seeing a page’s No index tag. Check the crawler rules documentation and sitemap protocol before publishing.

4. Check links and moved pages

Use URL Parser to inspect the path, query, and fragment. Repeated parameters stay in arrays, so ?tag=one&tag=two retains both values. The UTM Builder adds campaign fields while retaining other parameters. Leaving a campaign field blank removes that UTM parameter from the result.

When a page moves, choose your hosting format in the Redirect Rule Generator. Cloudflare Bulk Redirects require full source and destination URLs. Other formats use a source path. The Nginx result belongs inside a server block and matches the exact path; Apache Redirect also matches child paths. Test the old URL after applying a rule and update your canonical tags and sitemap.

Keep the published result current

Revisit metadata when the title, content, image, or URL changes. Check the public page and image, review the generated files, and verify that old URLs reach the intended destination. You can save tool drafts and presets locally, or use these utilities in the Mer Tools extension.

All tools are free. If they save you time, optional donations support development.
