More and more companies are starting to advertise with online influencers on their blogs, social media accounts, and more, and I expect this to just continue to grow well into the future. Whereas in the past, it was mainly celebrities that companies advertised with, but now, it is actually shifting to bloggers and other online influencers (such as Youtubers and Instagrammers!).
Google Blogger supports advertising through Google AdSense, PayPal links, and limited affiliate links. If you use excessive affiliate links, fail to add relevant content when including affiliate links, or get paid to increase someone's search engine ranking, Google will move your blog much lower in the search rankings, greatly decreasing your audience traffic.
