I think it depends on the topic. Why should I click on your blog’s link after watching one of your videos?
I usually don’t go from YouTube to a personal blog unless there is something that the video can’t give me. I don’t know your channel/blog’s details, but have you already considered giving away for free a digital file, a bonus if someone subscribes to your newsletter?
If you haven’t set up Google Analytics for your blog, I suggest you do it so you can learn how many people land on it through your YouTube channel.
