There are a couple of ways I have found to make some money, but I have not made much yet. You can sign up for momsaffiliate, passionfruitads and skimlinks. Skimlinks (http://skimlinks.me/1HXFk4o
) are affilate links you put in your posts, for example if you talk about a product you use, you can include a link to a site to buy the item and get paid a small comission. MomsAffiliate (http://sharedwithlove.com/l/2n3w18058o4
) and PassionFruitAds (https://app.passionfruitads.com/
) are places where you can sell side bar ads. Also, with MomsAffilate you can pick what ads you want displayed and get paid per click or sale depending on the company, I like this one because you can choose to only display ads that you approve or that you personally use, building trust with your readers.
The biggest thing is, though, that you have to have decent traffic. I know it sounds cliche, but you have to write great content to get the traffic and the ads you display can't look spammy. For example you can't just link to a random product in every post, sometimes you will need to have posts with no affiliate links or you will look like you are just trying to make money, and people will see through that. I honestly don't read blogs that are nothing but affiliate links and selling stuff, so just keep that in mind.
