The payment you receive per click depends on how much advertisers are paying per click to advertise using Google’s AdWords service. Advertisers can pay as little as 5 cents per click and as high as $10 or $12 in profitable niches, perhaps even more sometimes. You earn a share of that.
大体意思：每次点击能得多少钱决定于做此类adwords广告的人数，你和google一起分享这笔收入。（做那些投放广告多的行业可以赚到更多的钱。）
So your payment rates can vary enormously.
The rules forbid me from revealing my stats. However, in the tests I’m doing on five sites, the results have been startling – far better than I expected. The results are much better than I receive from many affiliate programs.
In the past, I’ve talked to affiliates who were happy to receive $5 or $6 CPM (per 1,000 page views). My results from AdSense leave such affiliate revenues far behind.
I’ve increased my use of AdSense. It’s a winner!
If my results are typical, it helps enormously if you build very simple, uncluttered pages so that the ads catch the visitor’s eye more than anything else.
Adsense收入可以高到令你难以置信，比其它广告形式赚的钱都多，关键是你的网站要干净，专业，有流量，并且广告要明显，或是紧密地和网站内容融合在一起。
If you hear about people achieving high payments per click with AdSense, remember that’s only part of the story. for high total earnings, you also need lots of page views and a high click-through rate.
获得高收入的关键是有很大的页面展示数和很高的点击率。
Here are some ideas on how to achieve those three things:
If you’re startingafresh designing a site specifically for AdSense revenue, you’ll want a simple design that makes it easy to paste Google’s code into a horizontal or vertical space on the site. For experienced webmasters, that’s easy.
重新设计网页时，不妨考虑到Adsense的广告位！如728*90广告位，336*280的广告位的放置放哪里好呢？设计时可以想想，留出一个好位置放广告是获得高收入的一个很重要的条件。To increase your click-throughs, design a simple, uncluttered page with the AdSense ads displayed prominently.
要获得高点击率，设计一个简洁，整齐的网页很关键！页面舒服些，广告很自然，很显著，点击率自然高喽！
Use white space, so that the AdSense panel catches the eye.
Adsense广告要抓住第一眼球。
Where possible, use ads high on the page. They catch visitors’ attention.
Experiment with borderless ads high on the page. (You can create borderless ads by setting the border color to the same as the background color. Look in your AdSense control panel under “Ad settings”.)
边框和网页背景同色可以获得不错的效果（就是没有边框），可以试试，真的不错的！
Try placing AdSense high in the left-hand column. That works well for super affiliate James Martell.
On very simple, one-column pages, making your article wrap around AdSense ads near the top-right of the page works remarkably well for me on a non-Internet marketing site.
Stick to only one topic per page – that makes it easier for Google to serve up highly relevant ads on your pages.
一个页面的内容只围绕一个主题，这有助于gogole提供和主题相关的广告。
Plain, bland pages with few competing hyperlinks result in higher click-through rates on the AdSense ads.
少一些和google相抵的链接，有助于用户点你的广告链接。
If you want to target certain high-priced keywords, use them in the file name, in the heading on the page, and in the first paragraph – in other words, use search engine optimization techniques.如果是有目的地做某一个关键词，网页名要用这个关键词，title,keywords,及第一段内容适当用些这个关键词。这和做ＳＥＯ有点类似喽！
If you change those keywords, Google will change the ads that appear on your page.
If you have trouble getting AdSense to serve relevant pages, check your anchor text – the words used in links on your page. Try changing some of those words.
如果发现出现的广告不是要关，可以试试网页上的链接文字，可以改成别的试试看。
Watch out for cases where Google has guessed wrong, and is displaying ads that won’t interest your visitors. Figure out which words are involved, and rewrite those words. Help Google by sticking closely to the topic.
Don’t worry about losing traffic via those clicks. If you can earn maybe 30 or 50 cents or more per click, you WANT to lose visitors!
You’ll also want keyword-rich pages, optimized to rank highly in search engines, so you can serve lots of pages.
提升ＳＥＯ。
Try using ads at the top of the page and again at the bottom. At first, this wasn’t allowed but AdSense changed the rules and it’s now OK.
试试底部也放个广告，访问者拉到底部说不定会点它一下呢？！
One of the beautiful things about AdSense is that you can now generate revenue from informational sites even if there are no obvious related affiliate programs. With more than 100,000 advertisers, there’s a good chance that Google will find ads that match your pages, better than the big ad networks can.
Don’t be tempted into trying to create thousands of spammy computer-generated articles. Human beings review sites for AdSense. Build useful, interesting sites. Google likes them.别老采集别人的东东，或者是电脑自动生成的东东，搞点原创东东，访问者喜欢，google也喜欢。
One way to create articles quickly is use Gary Antosh’s approach. He pays people to write articles for him - by the truckload. So far he has bought hundreds of them and paid only $5 per article. See How to buy articles for $5 - the details
Another way is to use works that are copyright-free. Here’s a book that describes how to find such articles: The Public Domain: How to Find and Use Copyright-Free Writings, Music, Art & More
However, that technique isn’t likely to be useful for long. At the very least, it would be wise to add your own introduction and conclusions to make your pages different from everyone else’s.
For long-term success, write your own original articles on a topic you’re passionate about. That way, you’re writing for humans AND search engines.
Serious tracking to maximize profits
How do you find out which AdSense ads get the highest number of click-throughs? How do you find out which ads are best at generating clicks that pay?
AdSense provides what it calls “channels”, and you can experiment to find out which pages on your site are generating the most revenue, which colors work best, what ad placement works best, whether you should use borderless ads, etc.
However, if you have a large site, you’ll find AdSense tracking via channels is seriously lacking.AdSense Tracker is a powerful php script that keeps detailed logs of all impressions and clicks on AdSense ads on all your websites without altering the ad code itself. The data can then be used to analyze the effectiveness of your sites, track different ad sizes and styles, or even individual pages.
想办法（如用渠道或是点击统计工具）来研究你的收入，这和ＳＥＯ研究流量是类似的。
You can track every click-through so you’ll know what your visitors are looking for. This makes it easy for you to build more perfectly targeted, profitable pages.
It can track unlimited domains and pages. It’s resource intensive and should be hosted separately.
