In my blog, I posted my own articles and I am not getting so much traffic per day, if I republish my all blog posts in the medium (Using Import story) it will cause any policy violation or any duplicate content in the Google AdSense when I apply for AdSense?
bharath No it won't cause any issue of Content policies because the article you publish in medium will get a canonical URL of your site.
This is how a canonical URL works.
Getting canonical URL is somehow similar to backlinks.
Ok Bro. Thank You
bharath Canonical URL of an article means the article you publish belong to the website of that specific canonical URL.
