Promoting hive on own blog/website is good idea but SEO is the key here. If you not apply on page and off page optimization then you will not get better result in your personal blog and other than that there are more things too. And social media traffic is depended on relevancy (for example , If you are sharing food subect post in technology subject group then it is not get result. And proper tags can attract relevant audience). And everyone don't know about SEO that's why i am recommend social media promoting for everyone because even beginner can do it. But if people can create own blog and promote hive on their personal blog/website then it will achieve better result than social media.
thanks for your comment.
