For example, to implement PPC using Google AdWords, you'll bid against other companies in your industry to appear at the top of Google's search results for keywords associated with your business. Depending on the competitiveness of the keyword, this can be reasonably affordable, or extremely expensive, which is why it's a good idea to focus building your organic reach, too.
Businesses and recruiters prefer marketing professionals with genuine knowledge, skills, and experience verified by a certification that is accepted across industries. In digital marketing, in particular, companies are looking for professionals with a 360-degree skillset that cuts across sub-domains such as PPC, social, email marketing and more. They are also prioritizing candidates that have exposure to many of the leading marTech vendors and are current with the latest best-practices.
