SEO helps improve your website’s visibility in unpaid search engine rankings (also called organic results). If your website is placed higher in search engine results, you are more likely to receive increased traffic to your website. Knowledge of SEO will increase your traffic, thus bringing in readers and the potential to earn money through those readers.
If you are using a free blog hosting service instead of your own domain name, you must provide high quality content with a limited number of relevant links or risk being shut down. If you are only interested in writing short, quick product reviews in order to earn money, you will need to host your own blog. Be warned that low-content, high-link blogs are a less reliable, though lower effort, way to earn money.
Selling private ads can come in the form of banners, buttons, or links. You can even make money writing sponsored posts where you write about or give a review of an advertiser’s product or service. Another option is to write an underwritten post or series, which is where you can write about any topic, but the advertiser pays for a “Brought to you by” mention in the content.
The time you invest to make any significant amount of money is the same amount of time it takes to build a course or other offerings. If you want to make good money with ads (in the thousands), then you need to get 100s of thousands or millions of pageviews a month. This takes time and in that time you could just as easily build up your mailing list, create an infoproduct and make thousands whenever you want.
Make it easy for readers to browse – If you want more pageviews, you should make it as easy as possible for readers to read your other blog posts. You will want to make it easy for readers to find your blog homepage, categories, tags, search bar, and so on. Also, I recommend including links in every single one of your blog posts, so readers can easily find related topics.
