Google wants content to be created by oman cell phone number experts in a particular field so that these experts can prove their expertise. It’s not a person’s work experience that matters. Expertise is determined by the presence of certifications, links, speaking at events, visiting professional websites, etc. Also, do not forget about the data that you publish on your site.
All the data that you operate with must come from somewhere. And you are obliged to refer to something. If you provide any numerical indicators, figures and other statistics, you must indicate where you got such data from. And accordingly, such information must be linked to reliable sources. Since content that is not supported by anything is unreliable in the eyes of the search engine.
