According to common belief, duplicating material has very little effect on your search rankings. However, it can sometimes harm them.
Google won't punish your website for having duplicate material on it alone. Duplicate content can still be harmful to SEO in a variety of other ways, though.
Typically, search engines such as Google are unable to determine the original author or URL of the article.
The idea that duplicate material exclusively applies to full articles or web pages is another common mistake.
One easy technique to get rid of annoying duplicate material on your website is to use 301 redirects.
The concept of "link equity" defines the way that some links transfer authority and value from one website to another.
Even though they are largely innocuous, small URL variations result in duplicate content.
Make sure that any issues regarding duplicate content are taken care of by getting in touch with the websites you are syndicating with.
