The first step is to decide on the topic of the blog. The most common mistake already at this stage is to make a blog at once about everything that is interesting to its author, when next to serious articles with an analysis of a particular area there are links to new videos with cats.
In order for the blog to be successful, and, as a result, to have the potential for monetization, when choosing a topic, you should use the following rules:
there are few blogs on this topic, or among them there are no serious projects with great popularity;
commercial theme. Here it is important to imagine in advance who will be ready to place ads with you, based on the potential audience and the subject of the blog.
the topic is actively discussed in the media. This includes mortgages, loans, education, etc.
the topic is interesting to you personally, and you will be happy to write about it a lot and regularly.
Creating blogs to earn money
In almost any SEO blog, you can find a post dedicated to the monetization of the blog itself. At the same time, the author does not hide the fact that the blog itself was originally created with the aim of its total monetization. There are quite a lot of such double blogs, they are very similar to each other and are of no interest to anyone except the same bored optimizers, hoping that someone inadvertently burns them an interesting topic.
Would you buy a book in which the author does nothing more than tell how he wrote the book and how he intends to sell it? Hardly.
Therefore, do not repeat the mistakes of trying to turn one blog into both a platform for selling links or other income, and a guide on exactly how to blog, and a space for communicating with like-minded people. Unless you're an SEO expert and capable of giving people more than a basic level of advice, this blog is unlikely to be successful.
Home page update
For a blog to be popular, it needs to be updated regularly. Here it is important to find a good balance between quantity and quality. Blogs on which new posts appear less than once a week, twice, look dead, and a diary in which a dozen meaningless notes appear every day, I want to remove from my bookmarks for being annoying.
Alternatively, you can focus on articles of an encyclopedic nature that will exhaust a particular issue. Of course, this involves a lot of time and creative effort. However, this is one of the best ways to get people to link to your blog and recommend it to others.
