Google Adsense
[March 2006] If you're not averse to a little carefully selected advertising, you can make a few dollars from your website without a lot of effort using Google's Adsense.
Targeted ads.
Adsense ads are contextual — that is the ads displayed are related to the content on your page. If your website were about occupational overuse syndrome (OOS), for example, it would not be surprising for the Google ads to provide links to software to help prevent OOS, ergonomic aids, remedies, and information.
You can see a live example at this page: http://acronyms.thefreedictionary.com/Occupational+Overuse+Syndrome+(repetitive+stress+injury).
As a website owner you can make extensive choices about layouts and formats for the ads. You can include ads only on specific pages, or on every page of your site. You can tuck them away in unobtrusive corners or push them right at the visitor. Best results come from blending ads in with your site.
You can block certain ad providers if you wish, so you don't have to just accept ads from groups you may not wish to promote. Google say this in their Adsense tour:
"Google's ad review process ensures that the ads you serve are not only family-friendly, but also comply with our strict editorial guidelines. We combine sensitive language filters, your input, and a team of linguists with good hard common sense to automatically filter out ads that may be inappropriate for your content. What's more, you can block competitive ads and choose your own default ads."
Worth investigating.
Some community groups will find it totally inappropriate to include ads of any kind on their site, but if you feel carefully selected ads would not be a problem and you wouldn't mind earning a few dollars for your group then it's worth investigating Google's Adsense.
