Google Analytics is free to use, and the insights gleaned from it can help you to drive further traffic to your website. Use tracked links for your marketing campaigns and regularly check your website analytics. This will enable you to identify which strategies and types of content work, which ones need improvement, and which ones you should not waste your time on.
It doesn’t pay much, but if you’re a healthy person and want to make a bit of extra money online, the AchieveMint app will reward you for doing things like walking, tracking your food, or taking health surveys. AchieveMint works by connecting to fitness apps you might already be using like Fitbit, RunKeeper, Healthkit, and MyFitnessPal and then giving you points for certain actions. For every 10,000 points, you earn $10 with no limit on your earnings.
