Most bloggers wish to increase subscribers.
Clearly, there is interest in the topic. My posts about how to get and find 3,000 blog followers* are among my best performing posts.
If you want blog followers, why not learn from the best in the business?
The influencers in blogging have tens of thousands of followers. What criteria do they use to decide who to follow themselves?
I invited 15 of them here to explain what criteria they use to follow other blogs.
If they follow blogs with certain criteria, and you put those qualities into your posts, you will increase your following.
If the best in the business say these characteristics are good enough for them, then they should be strong enough characteristics for you to turn your visitors into permanent subscribers.
