How can I prevent the Googlebot from indexing duplicate URLs?

Question

I have duplicate URLs for each ad page. For example:

https://example.com/ads/2161/%D9%84%D9%83%D8%B2%D8%B3_GS350.html

https://example.com/2161/

I used the second URL for Twitter and Instagram posts.

So I see a message in Google Webmaster Tools that there are duplicate title tags and content.

How can I fix this issue, I want the Googlebot to index only the first URL, not the second URL.

Hi Just set canonical URL and it should fix it.

Example:

URL 1: http://www.example.com/product/first.html

URL 2: http://www.example.com/first.html

Let's say if you want google to crawl only URL 2 then in the first URL set URL 2 as canonical URL.

Code to go in the head section of URL 1:

<link rel=”canonical” href=”http://www.example.com/first.html” />
