First, locate a piece in your industry that has performed well (in terms backlinks).
It's also a great way to obtain backlinks. Old content may have backlinks already, which can be great! Check out the content you've created in order to build backlinks. Create and update relevant information, and make it better than the one you have.
According to my experience, it takes approximately four week for an article that you reply to to HARO to get published. Even if no follow-up email is sent by the writer, it takes about four weeks for an article to be published. Keep checking the publication to see what happens if your quote does make it into the final piece.
If people don't know your identity, they won’t link to it.
