I have used WordPress.org to develop a business for my company and I have been able to generate a good income through my business.
I have also done the basics of SEO with WordPress.org and I have found ease with ranking on top search engines like Google, Bing and Yandex and also driven good traffic and customers to my website and made good income.
WordPress.org is what I can say every website owner should switch to for easy customizations and good search engine results.
As a total newbie, you can own a WordPress.org website and control your business while you take charge of everything in your business online some other blogging platform=s that will not allow you the full ownership of your business.
Also WordPress.org does not look for your overall idea as a programmer but just the basic concept of knowing what to do while faced in your laptop.
