Google Adsense is one of a number of online ad networks that can let you earn money per click or per impression. The entire process of setting it up on your site is quick and needs very little experience. AdSense allows website owners to monetize their sites by presenting adverts that are relevant to their specialty and target audience. To add promotions that fit in with your site's native content, you can choose from a variety of ad types and styles. The pros & cons of Adsense HeatMap :

• Let's begin with the benefits of using AdSense. For starters, it's free, and Google creates your adverts. This saves you money as well as the time you would otherwise spend creating and optimising your own designs. Another benefit is that you can use a single account to post adverts on multiple websites. This can be useful if you have multiple enterprises and wish to monetize them all with adverts. You can also choose how your adverts are displayed and personalise their appearance.
•  One drawback of using AdSense is that you won't be compensated until you've earned at least $100. You're also restricted to using only Google's ad network, and you can't use any other ad network alongside it. Furthermore, your account may be terminated at any time for a variety of reasons, including policy violations and click fraud. If you exclusively use ads to monetize your site, you could be losing a lot of money. Notably, while advertising can be a source of passive revenue, they require a significant amount of traffic to be profitable. To be prominent enough to draw the quantity of visitors you'll need to start seeing returns, your site must rank highly on Search Engine Results Pages (SERPs).
