Do you want the most valuable backlinks that Google loves?
Then write an article on your topic and submit to these websites in return for a high quality, relevant backlink.
You want to impress these website owners so make sure you put in the effort to create a truly great article. Keep in mind that the link authority that you get from such a post can be worth several hundred links from article directories, maybe even several thousand. The relevancy and trust that you get from these types of links is extremely powerful.
