Not only that, but you should also have a look at their certifications and awards which can effectively back up their expertise. In this regard, you should ask them whether they have specialization in any industry, location, or service and do they provide more than just SEO. All of these will help you to get a clear understanding of the services as well as specialties of the SEO experts.
