I am a new Adsense user. I am trying to learn how to maximize my Adsense earnings to get high CPC ads and increase CTR.
Based on my understanding, the ads on travel, business, finance, and health niches have a high CPC rate. If ads on these niches appear on your site, you will earn more money per click compared to other ads.
Adsense is contextual advertising and analyzes the visitors' search behavior to show ads on the site. In other words, adsense analyzes the keywords on the website and try to match the ads with the same niche. If your website is about travel, Adsense is likely to show ads related to travel.
Likewise, adsense also shows the ads that visitors previously engaged with on other sites or the ads related to searches made previously. For example, if a user had searched for a hosting company on Google, it is very likely that the ads on the next website he visits will be about hosting.
