Your newsletter is all yours. Unlike social media sites, your newsletter and email subscribers are all yours, and you have their undivided attention. You don't have to worry about algorithms not displaying your content to readers, and this is because they are your email subscribers. You aren't fighting with anyone else to have them see your content.
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.
Hi Sam! I love your site. We should definitely connect. I’m a school counselor and recently launched a site for parents to address pertinent teen topics. Like you, I struggle with the ultimate service I’d eventually offer on my site, but Ramsay’s idea is a great start. He’s absolutely right that people are looking for fresh content for their sites! Best of luck to you and I hope we can collaborate.
