What are the best topics to blog about? There are thousands possible topics that a blog can have, and it is going to be up to you to choose the one you are the most interested in. You may get an idea to blog about search engine optimization, or maybe you also got a few other ideas not directly related to this particular subject. There is a chance that there are a few other things you are fascinated about that you would like to write about. Are you worried about starting a blog that would cover more than one topic? I think that there is nothing wrong about blogging about two or three different topics on your blog. After all, there have to be people who also share your interests. While staying focused on the topic of a blog is a very important factor in retaining visitors, writing about a few topics might even attract more readers that will come to a blog in order to read about a variety of topics. Of course, there has to be moderation in everything, so it may not be a good idea to blog about a dozen unrelated subjects. That is because there may not be that many visitors that have interest in all of the topics you would discuss. On the other hand, if you are going to discuss two or three topics, then your blog will be very attractive to all of those people that have an interest in those topics.
