Adsense is the main monetization choice for bloggers and vloggers. Sadly, a lot of people are rejected by Adsense. When Adsense does not approve you, making money from your blog and videos becomes limited. I have not yet reached the monetization threshold on my youtube channel, therefore, I do not have any experience with approval and rejection on youtube, however, I use Adsense on my blog and I can tell you what exactly works and what does not. Here are some important things to consider.
Content Quality
You need unique, original, and well-written content
Content Count
You need a substantial amount of content on your site, at least 25 articles with at least 1000 words each.
Important Pages
Your site needs to have important pages like About Us, Contact Us, and Privacy Policy
