A niche focuses your blog’s content. If you decide to just write about any subject that comes to mind, your blog can be hard to understand for visitors and can “dilute” the core of the blog. Visitors may not be able to make sense of what your blog is ‘about,’ and this can impact your bounce rates and retention of your readers.
If your blog covers too many areas, it will be harder to encourage first-time readers to engage with additional posts during their visist that may not be relevant to their interests.
When choosing to enter a specific blog niche, the decision isn’t one to be made in a hurry. You’ll likely be working in this area for years, so you want your subject to be something you find interesting and enjoyable. However, it also helps if it already has an established audience and opportunities for profit.
Many people make the mistake of starting a blog having only the passion in mind and hoping it will pick up and become a big success (overnight). Nothing could be more further from the truth.
Of course, some Niches are easier to monetize than others. But broadly speaking, any niche where you can find and solve a problem your readers are struggling with will bring you income. Remember, profitability is more about finding a popular blog topic that can also be monetized rather than one you’re passionate about.
