Running a blog and getting it to make a profit are two different things. If you want to find big success with your blog, regardless of the niche, there are a few things that you should be doing, such as...
Don't Stop at Selling Ads: The first thing people think of when they start a blog is how they can earn money through the selling of ads, which are usually viewed as the best form of monetization for blogs (a falsehood). The simple truth is that ads, on the surface, look like the easiest way to earn money on a blog but they aren't the only source of income out there. You could also be an affiliate or sell your own stuff with your blog--all of which can net more than ads. Unless you already have a popular blog (or until you make your blog popular) focusing on other revenue sources will work better than focusing only on advertising. You can easily find affiliate products to promote on your blog, or even sell your own services. When you allow yourself to be creative, all sorts of monetizing opportunities will open up to you beyond basic advertising. Quality Comes First: At first you might have grand plans of building up a really large blog with plenty of content. Focusing on quality posts for your blog will give you the quantity you need over time, so there's no need to rush to get more on there. Making a blog popular does involve updating it on a regular basis, but your first priority should be quality. For example, if you only have a short amount of time to work on your blog, use that time to create one post that is great quality, instead of trying to cram several lower quality posts in the same time.
Don't Rely Solely on Social Media: Social media is being touted as the biggest and best way to reach online success these days. This belief means far too many bloggers feel pressed to get onto every social media site they can find and make themselves known, even if it doesn't bring any results. Rather than trying to keep up with all those different social sites, there are other parts of your blog that will benefit from your focus instead, like more content. Of course, social media isn't totally worthless, but it only gives results if you're doing it correctly. For example, you could aim at just a couple of larger social media sites and leave it at that.
