You can add a directive to your website's robots.txt file to disallow indexing of specific URLs. To disallow Google from indexing a URL, you can add the following line to your robots.txt file:
User-agent: * Disallow: /your-url-path
Replace /your-url-path with the actual path of the URL you want to block from indexing.
You can also use the <meta> tag in the HTML of the specific webpage to instruct search engines not to index the page. Add the following meta tag within the <head> section of the HTML:
<meta name="robots" content="noindex">
This tag tells search engine crawlers not to index the page.
