Over the years, Wikipedia is becoming a minefield for marketers causing more trouble than it is worth. Wikipedia is effective and can be used by content marketers to assist with SEO and donate to the assignment of this world's largest encyclopedia.
Content marketers misunderstand how backlinks work in Wikipedia. They believe that in case the topic is applicable, simply adding a link to the"external link" section of a webpage is great enough. Not so.
Adding a hyperlink to Wikipedia is like surgery -- if not performed properly it can cause issues, including prohibited from Wikipedia and getting your domain that is additionally listed as spam.
Keep and it is so tough to obtain a Wikipedia link which I stopped offering quite a while ago to this support. If done correctly, it can still be a great benefit to your SEO.
