Can I Use One Account for Multiple AdSense Websites?

I can answer that with a simple "Yes." In fact, when you have more than one AdSense website, you simply make more money. A big plus for me is that you don't even have to notify Google when you use your codes in other places or recently started blogs or website(s.) There is a small but... any site that you add must conform the program policies of Google AdSense. That's important because if your accounts get suspended or even worse, get's terminated, that means ALL the ads that are displayed on you URL's will be gone and so is your money, keep that in mind.

You can easily copy and paste your code from one (mostly the first) site and paste it easily into your new location.

These same rules apply when you add an AdSense for Search box on your (new) website or blog. All you have to do is choose all the parameters from the ad choices displayed, just copy the code into your new site or blog within the previous old website or blog In the beginning,the advanced Google WebCrawler system detects your code easily and your good to go. Good chance you have seen eBooks for sale that are telling you all the "AdSense secrets" and you may feel the urge to buy one, but is this a good investment or...

Like any other cash generating method, there are some pitfalls, pros and cons you must be aware of. The Google AdSense Program is one of the (if not the number 1) most popular programs online, but that's a no brainer because everything and every website or method where some money can be made is popular. Just try it, it's free! If you doubt that just type a Google search on "Google AdSense Program" and you will see the HUGE amount of results found! There are those promising they make thousands and thousand of dollars each and every month with the popular publishing platform.

But the real fact is that Google AdSense will tell you everything you need to know - for 100% free. They have multiple support sites divided over the sections (addsection, placement help, keyword research etc.)

And another but VERY good and reliable source is other users. You will notice that most people are willing to answer your questions about anything related to AdSense. And if you really have a question you can't find the answer to by other users you can always send a email to the Google AdSense support staff. I prefer experienced help from other users because you get your answers right away, and that's not always the case with emailing Google. Why won't you try it, you have absolutely nothing to lose, get up and make some free money! You will notice that when you've started slowly learn more and more and by time see you revenue grow, but take it slow, that's the only REAL method if you're looking for long term income.
