How to Noindex question mark URLs? - ?show

Question

Doing the Google command site:mywebsite.com/my-question-post-url I can find multiple pages indexed with ?show parameter.

For example:

• https://fuzzer.it/1/cosa-ne-pensate-della-fender-cd140-sce
• https://fuzzer.it/1/cosa-ne-pensate-della-fender-cd140-sce?show=3
• https://fuzzer.it/1/cosa-ne-pensate-della-fender-cd140-sce?show=6​
• https://fuzzer.it/1/cosa-ne-pensate-della-fender-cd140-sce?show=15

How can I noindex all those duplicate results?

Answer 1

You don't need to 'noindex' them. Q2A adds the 'canonical' meta tag to tell search engines the correct URL of the page (the one without the 'show' parameter). I checked and your site has the correct tag showing.

Thank you, I don't understand why Google is indexing anyway. But okey, I will wait until the next crawl from Google bot and I will check again.
