Design to maximize online ad revenue

Since PPC ad networks target their ads primarily by topic, rather than geography or demographics, that makes these networks work better with niche topic websites than with sites that target their readers by geography or other demographics, such as gender, education, income or political affiliation.

For the system to work well for you, the PPC network's spiders must be able to determine a topic for each of your webpages and then must match keywords or phrases that advertisers have bid upon. That means the advantage goes to websites where each page covers a distinct and easily identifiable subject. So if you have a blog that covers a mishmash of topics on a single URL, you won't elicit the targeted ads that lead to high-paying clicks.

If you want to use PPC ad networks, organize your content to limit individual URLs to a specific topic. Break long blogs into individual entries. Archive old posts and stories by subject matter, not just by date and author. Stay active on discussion boards, keeping threads on topic and directing folks to more relevant pages should they stray toward other subjects. Use keywords in headlines, decks and URLs whenever possible. And spell out keywords, phrases and proper names on first reference, rather than using acronyms throughout the piece. (See, old fashioned copy editing rules *can* help you make money!)

Well-organized pages on individual topics also show up better in search engine results, attracting Web surfers curious about a specific keyword, who are more likely to click on a targeted ad. Publishers who create evergreen articles that are likely to attract a high number of links and clicks over time will do best in attracting search engine traffic to their ad-supported webpages. If you publish time-sensitive articles, which are not likely to have a long-enough shelf life to attract significant search engine traffic, consider swapping out or archiving articles on the same topic to a single URL, so that URL can get linked to and picked up in search results.

Where you place ads on a page affects how many of your users see them, and click. According to recent Google research, top performing ad formats include:

• Large box ads placed in the middle of your main content column;
  
• Skyscraper ads placed in a left-side column;
  
• Leaderboard ads placed at the top and the bottom of the main content column.

Customize the ads' colors to match the background, type and navigational colors of your site, too, to eliminate "banner blindness" and maximize their visibility to your readers.

Then keep an eye on your ads to make sure that they remain relevant to your site. To a reader, ads -- like anything else on your pages -- are part of the content of your website. If an ad network fails to deliver consistently relevant ads, dump it and try something else. Respect your readers by not bombarding them with irrelevant advertising and they will respect you by continuing to read your site.

Think twice before installing pop-up, pop-under and screen "take-over" ads, too. Many readers steer clear of sites that block their access to the content they're looking for with aggressive advertising. Keep your website a safe haven for these ad-weary readers and you can build its audience over time.
