Some web programmers create their own website and make a significant effort of maximizing the web content, and their AdSense income as well. They do this by following these tips: The use of varied of traffic-generation techniques that will include but will not be limited to online advertisements. The use of some text contents on the website that will encourage the visitor to click on any of the advertisements through phrases like "Advertisements" or "Sponsored Link". There are some prohibitions though because Google prohibits the use of phrases such as this "click on my AdSense ad" just to increase the per click rate of the website. Building valuable text content on the website that will lure visitors into the advertisement. Google assesses a higher rate when these advertisements are clicked. If you want to get into a business that will truly earn, then get into AdSense for Google. You could get paid by making a website and displaying advertisements that will encourage visitors to click the ads. The rate that Google pays for every click may vary. But what you need to do is just create more websites and see how your income multiplies. You don't need to sell anything here or target different markets. Just develop more websites and experience passive income at its best.
In my opinion I think that it is better to build a bigger site with more articles rather than to have a lot of smaller sites, It really depends on what method that you are using.
for adsense use, I guess its really better in article rich content to give information for users where adsense can gather much relevant content to show.
Sure, build nothing but sites for adsense. Join the millions of other MFA sites. A real webmaster builds a site for his visitors, not for adsense.
