How Does Google AdSense Work?
When you place AdSense on your site, Google programmatically determines what your site is about and runs ads for businesses that are a great match for your site. If you run a blog that rates wines, your visitors will likely see ads for food and drinks. If you write about movies and comic books, then a wide range of what would be considered "geekier" entertainment will show up in the ads.
Then based on your traffic and the number of people who took actions with your ads, you'll get a cut of the profits from Google, and they'll pay that cut out to you once a month.
Is Google AdSense Right for Your Site?
You may want to run your own ads on other sites, but the revenue potential represented by AdSense is not worth distracting potential customers from the things you hope to sell them.
If you're running a blog or building a website in which the sole purpose is to write or otherwise inform or entertain visitors then this is the answer: yes.
The more specific your site, like our earlier example about running a blog that reviews wines, the more money you're likely to bring in. And the better your content, the more likely your site will get visitors and increase the value of the ads you're displaying.
How Can You Get Started with AdSense?
Notice the wording at the end of that last sentence: "submit your application." Google looks over every site that signs up for the AdSense program to determine whether or not that site is both legitimate and a good fit.
If your site appears to be spam, you'll be declined. If your site is mostly empty, you'll be declined. Ideally, you should wait and apply to be an AdSense publisher after your site is established and has been running for at least a month. That way you're providing Google with enough content to properly judge (and accept) your site into the program.
Once you're accepted, it'll take at least a few days for ads to begin showing up. You can drag AdSense elements anywhere you like and can even place multiple elements on the same page. Consider limiting the number elements to three or fewer per page or per blog post, since Google may view more than that as too many and may not run any ads in the excess elements.
One other very key detail to note is that you can adjust the size and type of ads being run by clicking on an AdSense element within Weebly and then going to Advanced. You can choose completely different settings for each and every AdSense element you place on your site.
What Should You Expect from AdSense?
Will Google AdSense allow you to quit your day job next week? Nope.
Will Google AdSense bring in a substantial amount of money? At least not right away.
Like any other business model, what you put into Google AdSense will greatly influence what you get out of it. If you focus on keeping your site continually updated with new content while working to bring visitors in, then you'll see your AdSense revenue trend upward. If you only update your site occasionally (if at all), then the money you make from AdSense will likely be negligible.
The best way to view Google AdSense is as supplemental income that, if everything goes well, can over time help you move on to bigger things. It can absolutely be a great way to start making extra money with no real risk involved other than the time you put into your site.
