You know that you have to put high quality content on your blog, but realize that you cannot stop with that. The whole concept of the sticky blog is very much doing all the things to make it sticky. The ability for you to make your readers want to leave a comment and return to do more is paramount. What we now want to do is move into a discussion about what you can do to secure more blog comments.
If you take a look at blogs with huge traffic, you will see how they encourage readers to participate.
The world is full of rewards program examples, and you merely have to tailor something to your blog. You will get feedback from this approach in the form of a response from people. Look at authority sites so you can get creative ideas, and you can always build on something. So that is just one approach to the problem, and the good news is there are many more available.
If you want something different, form a circle of bloggers who agree to to help each other by providing intelligent comments. Now, once you have that in place, then you can make more blogs in other niches and get started with comments right away. The need for this is not permanent for one blog, but it is still useful for newer blogs you build. We are just informing you of what can be done, and this sort of helpful network is barely even a gray hat technique. But another tact that is similar is just hiring people to comment on your blog.
You can do your own commenting on related blogs, but remember that will need to be approved which may not happen. This is not difficult to do, but you have to be consistent in your efforts. This is not a short term strategy, but it is one that can pay off over time. Keep in mind that relevancy is very important to make this approach successful for you.
When you are working on your blog, you will have to address comments and more in parallel. If you continue exploring this topic, you will see there are many more techniques you can use. So then take the initiative to put into practice the things you learn, and you will see a huge difference. Any time you begin implementing new methods, it takes time to get things down properly and see the results. Plus, do remember that future blogs you develop can benefit from these strategies.
