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.
AdSense is a contextual advertising network that places partner (business) ads on your website. It’s easy to set up—all you have to do is copy and paste some code given to you from Google in the places you'd like the ads to appear on your website. Google will then show ads from advertisers that are a match to the content on your website so that ideally your website visitors see relevant ads.
Double check yourself, before you double wreck yourself. Make sure everything you send to a company, whether a résumé, an email or a portfolio, is good to go. Double check your grammar and wording, and for God’s sake use spell check! This is especially important when it comes to the company’s name. Don’t spell their name wrong and be sure to type it how they type it (e.g. Problogger, not Pro Blogger).
Use a system like W3 Total Cache or WP Super Cache and turn on browser caching to ensure that you speed up the delivery of your webpages. In the beginning, this might not seem as important. But as you grow and your traffic increases to thousands of visitors per day, this will be critical. Use Google's Page Speed Insights to test things before and after the installation.
Perhaps the most popular network for placing these types of ads is Google AdSense. With this program, you do not need to be in direct contact with advertisers; you simply place the banner on your site, Google chooses ads relevant to your content, and your viewers click on the ads. There are countless similar programs available if you find that AdSense doesn’t work for you, such as Chitika, Infolinks, and Media.net.
