I think the biggest thing about wanting to get new visitors is that you need to remember who you're writing for! After all, these people have hundreds of blogs and thousands of websites vying for their attention. Why should they read yours? What do you have to offer them?
This doesn't mean that you have to change every single one of your posts, but you should definitely try to remember that you have readers! If you write a review blog, a post about your dog is most-likely not why they continue to visit. If you go from talking about your kids daily to just jumping in with sponsored content, you're not likely to keep those readers who came in to see you talk about your kids.
On that same vein, try to provide useful content from your own life experiences. With the invention of social media, a lot of us (myself included, on my personal blog) fall into the habit of saying “Well, I have nothing to write, so I'm going to ramble about what I ate last night!” Try to make posts when you think they'd be appeal to your writer. It's okay to make the random rambling post, but if you do it too often, your readers aren't going to want to come back every day. Blog posts can provide useful content as well. Instead of talking about why you liked what you ate last night, maybe you should review the restaurant? Give the recipe of the food you ate? Talk about the diet you're on? Talk about how you found ways to reorganize your kitchen to make it easier to cook? Things like that can definitely make a returning audience rather than talking about small details of your life all the time.
On that same vein, be careful about what you ask your audience to do. If a lot of your posts are asking your readers to purchase or do something for you, readers may become annoyed by it and stop following. Readers are there for a good experience, and especially if you're a review blog, they love recommendations, but asking for frequent donations or talking about how desperate you are for money and their donations may not win you return followers.
What type of content do you try to stick to?
