Affiliate marketing is another way to make some income on your blog, however it takes a lot of work and you will need to have a big following.
Basically, you sign up as an affiliate and start promoting your unique URL. These affiliate companies then provide you with a tracking code so that if anyone clicks the link or the photo that has your tracking code, and purchases a product, even 30 days after the original click you earn a commission.
Be careful not to have too many affiliate links in your blog though as Google may pick it up as spammy. You can use your designated affiliate link in your social media too by shortening it with Hootsuite, Buffer of bit.ly and writing a catchy sentence. Again, you will need to have a big following to make decent money from affiliate marketing.
Affiliate marketing can help you earn money while you build your business, but make sure you stick to your niche when signing up for programs.
Your goldmine will be your list that you build, where you can start sending your affiliate links to your database, just be careful not to overload with too many as you don't want your subscribers to get sick of you selling to them and then unsubscribe.
Keep away from products that only pay small commissions i.e. 5% of a $15 sale isn't going to make you a millionaire in a hurry.
Test the product yourself so that you are being authentic, it will show through. You might even do a review of the product on your own website with a link to your affiliate.
Affiliate links should always be NO FOLLOW.
