Have you researched and found that paid guest blogging will be an incredible way for pulling in more traffic organically? If you agree to experience the same traffic drive that will lead you to more conversions then you should hire a blogger for guest posting.
While interviewing- ask the blogger about his/her past experiences, their favorite niche and the expertise on any particular niche/category they have etc. Don’t forget to check their total experience and the efficiency of researching before hiring. At the same time, check the previous blogs and guest blogs they have written and their current ranks in the SERP.
