Which one is better video blogging or simple blogging?

One needs to have a good balance of both. Your ratio should vary based on:

1) Type of topic

2) Audience (B2B or B2C)

3) How fast you want the content to go viral?

4) Age group of your audience?

Often podcasts are better than a tradition200-350 word blog post.

Both are good in their own ways. It all depends on how your audiences like to consume the information on your blog. Mix them up and don't go solo on just one type of content format.

The perfect topics are these which contain the three types of blogging together " video , picture, and writing " .

So that both video blogging or simple blogging is not perfect if we follow it as an independent form , but if we mixed them together here we can say it's perfect
