1. PPC Ads (Pay Per Click)

Google Adsense is the most popular and widely used option.
They serve contextual ads (image or text) based on your
content, and pay when someone clicks on the ad. How much
you make on Adsense depends on several things. First,
advertisers bid on keywords, so if you happen to write about
a topic that has high paying keywords, then each click will
be worth a lot more than another topic with low valued
keywords (keywords that has really low bids). Also, people
who came to your site from search engines are more likely to
click on these ads than people who are repeat visitors. It
makes sense then to spread out your Adsense ads to provide
easy access for search visitors.
Other PPC options include Bidvertiser and AdToll .

2. CPM Ads (Cost Per Thousand)

Unlike CPC ads, CPM ads pay per impression. Viewers don't
need to do anything for you to be paid. You just need to
serve the ad to them. The downside is that you're paid
almost nothing for each impression. Rates can go as low as
$0.10 per thousand impressions. But it's still a good option
to use in conjunction with CPC ads. CPM ads can be placed
in less prominent spaces (below the fold) whereas CPC ads
should have better position. Most ad networks that offer CPM
ads have CPC ads thrown in as well. You can set your own
prices and remove unappealing ads.
Networks that offer CPM/CPC ads include AdBrite and
ValueClick Media.

3. CPA / Affiliate Ads (Cost Per Action)

CPA ads pay per action . Viewers don't just need to click on
them, but they actually have to do something, either sign up/
register or make a purchase. Not surprisingly, they are the
highest paying ads. However, how likely your visitors will
click on the ad and perform the desired action will depend
very much on how relevant the ad is to your content. For
example, a site about digital photography may do very well
showing digital camera CPA ads. Some sites are much better
suited for CPA ads. Consider whether any CPA ads would add
value to your visitors.
Popular affiliates networks include Commission Junction,
Adfish, and Amazon Associates.

4. Text Links

Text links work the same way as the above. You set aside a
space on your page and text links will start showing up when
they are purchased. You need to submit specific pages into
the inventory, so enter your most popular pages (homepage,
category pages, and very popular articles). Rates are based on
your PR, which has to do with how many other sites link to
your page. If you often get linked and mentioned, text links
may be profitable for your site.
Some text link companies are Link Worth , TNX.net , and Text-
Link-Ads .

5. In-text Advertising

In-text ads don't require any additional real estate, which is
attractive to many site owners.
Ads are attached to text in
your content, showing up as underlined or double underlined
words that are clickable.
Some will pop up a little
advertisement when the word is moused over. Many viewers,
however, find these ads distracting.

Popular companies are Kontera and Vibrant Media.

6. RSS Feed Ads

Offering a feed of your content is essential. More and more
readers are using feeds to catch up with their favorite sites,
and not offering one will alienate a lot of readers who would
be interested in your content. There is yet to be a lot of
advertising options within feeds, but for now you can still
monetize the traffic to your feed.
