You also need to think through the concept: how exactly you will run the channel, what content format you will use, how you will engage subscribers.
To make it easier for you and your readers to navigate the content, you need to come up with several categories for the channel. The easiest way to do this is to analyze the categories of your competitors and add your own twist.
In order to stand out from the competition, the channel must have a recognizable tone of communication. For example, if it is irony, all posts should be permeated with it. Humor is acceptable in all topics, it can entertain subscribers and make the content more interesting. This, in turn, will have a positive effect on reach and audience retention.
The texts of the posts should be short, informative and useful, without unnecessary meaningless information. It is necessary to use formatting and accompany them with pictures in a single style. Long texts can be tedious to read, even if they contain valuable information.
An example of what should not be done is publishing trivial truths as content. For example, the statement that oatmeal is healthier than French fries does not have much value for the audience. Such trivial statements are unlikely to interest readers and encourage them to return to the channel on a regular basis.
