Ads can work well in-between other stuff. On a games site of mine, some of the games don't contain ads next to the game area; the AdSense ad will only be shown in-between game rounds. This is the time the visitor is not concentrating on performing a task but might take a small break, and be open to the option of visiting new sites.

Put too much emphasis on AdSense and your site may be linked to less. The more available space you dedicate to AdSense on your site, and the less you differentiate between ads and content in your design, the more money you earn with the program, right? Not quite. While pushing the AdSense may result in short-term gains, it might also convince some visitors that the site is too crowded to be worth visiting again. And some of those visitors may also be bloggers or other people who might otherwise help to promote your site with links to it. And the less your site gets linked to, the less traffic it gets, meaning AdSense revenues may go down in the long term.

Even if you get huge traffic, the AdSense income from the site is more dependent on the site type and audience. Google targets AdSense ads automatically to the site content. Or at least, it does so ideally ? but some types of content fare better than others with this targeting. I noticed for instance that AdSense does better on a games site than on a technology blog. I also heard people say that AdSense does quite good on product oriented blogs; say, one post solely about the iPod; another post solely about Gadget XYZ, and so on.

Image ads can be relevant and work for you, but they might also apall some visitors. Google's AdSense program gives you the option to choose between a couple of different ad formats. Two main groups are text ads vs text & image ads. When you choose the latter, Google will deliver what they deem works best for your content (or so one would hope, and it would be in Google's best self-interest to serve you the best possible ad, it seems).

However, Google doesn't really know your layout preferences, and they don't really understand when your audience thinks ads are "too much"; and considering image ads include Flash animations (which you can't disable, once you go for image ads), Flash animations may well push some people away. One thing you can do is to only show image ads in areas where they don't disturb the content, e.g. at the end of posts. Also, you might want to listen to visitor feedback on the ads being served; I received emails before that the blinking ad on this or that site made a person want to leave the site, at which point I blocked the specific advertiser via the AdSense Setup -> Competitive Ad Filter option.

2) How AdSense works

• The webmaster inserts the AdSense JavaScript code into a webpage.

• Each time this page is visited, the JavaScript code uses inlined JSON to display content fetched from Google's servers.
• For contextual advertisements, Google's servers use a cache of the page to determine a set of high-value keywords. If keywords have been cached already, advertisements are served for those keywords based on the AdWords bidding system. (More details are described in the AdSense patent.)
• For site-targeted advertisements, the advertiser chooses the page(s) on which to display advertisements, and pays based on cost per mille (CPM), or the price advertisers choose to pay for every thousand advertisements displayed.^[10][11]
• For referrals, Google adds money to the advertiser's account when visitors either download the referred software or subscribe to the referred service.^[12] The referral program was retired in August 2008.^[13]
• Search advertisements are added to the list of results after the visitor performs a search.
• Because the JavaScript is sent to the Web browser when the page is requested, it is possible for other website owners to copy the JavaScript code into their own webpages. To protect against this type of fraud, AdSense customers can specify the pages on which advertisements should be shown. AdSense then ignores clicks from pages other than those specified.

3)Abuse

Some webmasters create websites tailored to lure searchers from Google and other engines onto their AdSense website to make money from clicks. These "zombie" websites often contain nothing but a large amount of interconnected, automated content (e.g., a directory with content from the Open Directory Project, or scraper websites relying on RSS feeds for content). Possibly the most popular form of such "AdSense farms" are splogs (spam blogs), which are centered around known high-paying keywords. Many of these websites use content from other websites, such as Wikipedia, to attract visitors. These and related approaches are considered to be search engine spam and can be reported to Google.^{[citation needed]}

A Made for AdSense (MFA) website or webpage has little or no content, but is filled with advertisements so that users have no choice but to click on advertisements. Such pages were tolerated in the past, but due to complaints, Google now disables such accounts.

There have also been reports of Trojan horses engineered to produce counterfeit Google advertisements that are formatted looking like legitimate ones. The Trojan uploads itself onto an unsuspecting user's computer through a webpage and then replaces the original advertisements with its own set of malicious advertisements.
