Once you’re financially stable, I hope you start giving back. It feels good and people like the idea of supporting a good cause (they will be more likely to click your affiliate link in your disclaimer). This also means you don’t have to use as many links in your content and risk getting a penalized. Last year I donated $3,000 to Red Cross At Hurricane Harvey.
If you’re a skilled worker in a specific niche, like marketing, design, or software development, there are specialty marketplaces that cater just to you. These are amazing places to make money online as you know that the people visiting them are looking specifically for the skills you have. Check out places like 99Designs or Dribbble for designers, Cloudpeeps for marketing and SEO professionals, and TopTal, Crew, or Gigster for high-level software developers. Once you've built up your development skills, you can begin building a brand for yourself as a higher-value consultant and start charging brands for larger projects like implementing an entire WordPress security overhaul or migrating a website from http to https.
Hands down I’d say the best thing you can do is research 1 primary keyword, craft an enticing article title that includes your keyword (though it doesn’t have to be an exact match), spend time writing your search engine snippets (SEO titles/meta descriptions), and by far the most important is making your content as VALUABLE as possible through videos, nice graphics, table of contents, bold/colors/styling, etc. Small things like keyword density barely matter.
When was the last time you went to a new restaurant without looking it up online beforehand? Or bought a product that didn’t have at least a few 5-star reviews? It seems like more and more our world is run on reviews. And you can make money online by writing them. Get started by creating accounts on sites like Vindale research, Software Judge, FameBit, CrowdTap, Influence Central, and Modern Mom. However, before you run off and start writing, be sure to check the small print on each of these sites. Writing reviews isn’t a huge source of guaranteed income and you want to make sure that it’s worth your time before you get going.
