Google created the “Source” meta tags to allow us to write content and syndicate it to other domains. This way we avoid getting penalized for duplicate content.
There are two tags we can use for this, and a third that we already know.
This meta tag indicates the preferred URL for a syndicated article. If we were to publish the same content or very similar content in two different websites, we would use this meta tag to tell Google which one is the source.
For example, if we publish a post in https://blog.adWhite.com/cool-marketing-article/ and we want to syndicate to https://coolmarketingnews.com/adWhite-cool-marketing-article.html we would put the following meta tag in both sites:
`<meta name="syndication-source" content="https://blog.adWhite.com/cool-marketing-article/">`
This way we report to Google that the article in our blog is the source of that content, and neither page gets penalized.
It should be mentioned that if we already use `rel=canonical` we don’t need to use `syndication-source` because if both are present, Google will use only `rel=canonical`
If you need some help with this or any thing else is mad, confusing world of SEO and Google rules, let us know.
