In the earlier section, you can see that a majority of instances of duplicate content occurs when the URL structure is inconsistent. Therefore, it will be better to standardize your preferred link structure along with proper use of canonical tags. To let Google knows your preferred URL version, you can set your preference in your Google Webmasters account. Here some things that you could opt to set your preferred domain:

- Retains link juice
Next step after setting your preferred domain in Google Webmaster Tools is to set up 301 redirects from all of the non-preferred domain links on your site to your preferred ones. This step will make visitors learn about your preferred version.
- Canonicalization
Canonical tags can be implemented through several ways, such as follows:

- Manually point to the canonical link for all the pages
- Set up 301 redirects
- Use the hreflang tag to handle localized sites
Hreflang tag is important to help the search engines choose the right version of your content, especially after you use translated content. For example, you translate your English site into Spanish to meet the local audience language, you should add the tag, “<link rel=”alternate” href=”http://example.com” hreflang=”en-es” />” to the Spanish version of your site.
Following this method will avoid you from the risk of search engines considering it as duplicate content and in the other side, it will also improve the user experience when they want to be served in their native language.
- Use the hashtag instead of the question mark operator when using UTM parameters
To measure the effectiveness of different Channels, it’s common to use tracking URL parameters like the source, campaign and medium. But, when you create a link like http://yoursite.com/?utm_source=newsletter4&utm_medium=email&utm_campaign=holidays, search engines crawl it and report instances of duplicate content.
Hence, an easy way is to use the # operator rather than the question mark. In order to avoiding duplicate content issues, search engine bots come across the # sign in a URL, they ignore all that follows the sign.
