Optimizing your site for higher search engine rankings is an obvious activity for anyone with a website. Optimizing your site for higher conversion rates is another obvious one. But how about optimizing for higher advertising revenue — specifically, a bigger check from Google for the AdSense ads that you display on your site.

Consider for example if you had a website on redecorating for Do-It-Yourselfers. You might have a page all about "housepainting." But, as described in this article in USA Today about webmasters making money off of AdSense, "housepainting" isn't a great money term for AdSense revenue — it's only a 20-cent word. "Home improvement," on the other hand, is worth $2. That's a $1.80 difference.

So in effect you can give yourself a nice pay increase just by changing the keyword themes of your pages that display AdSense ads by creating new content pages around those keywords. And the real opportunists out there are creating pages about mesothelioma, a rare form of cancer caused by asbestos that lawyers are bidding on. That keyword is worth an order of magnitude more than "home improvement." But that would be sooo dirty! Thankfully I don't know anyone THAT dirty!

Hello from sunny San Jose. I'm at the Search Engine Strategies conference - THE place to be if you care about search. I'm going to be blogging the sessions, so stay tuned over the next 4 days.

Here's my first installment: a recap on the session I attended before lunch today on "Earning from Search & Contextual Ads". Panelists were: Jason Calacanis, Co-Founder, Weblogs, Inc., Will Johnson, Yahoo! Search Marketing, Scott Meyer, President & CEO, About, Inc., Gokul Rajaram, Group Product Manager of Google AdSense, Google Inc. and Jen Slegg, Owner, JenSense.com.

Jen from JenSense.com started the panel off:
Jen started off by comparing and contrasting AdSense w/ Yahoo's new YPN (Yahoo Publisher Network). Similarities include...
- very large pool of advertisers
- real time stats
- neither will tell you the revenue split
- can't show both YPN and AdSense ads on the same page

Differences include...
with AdSense:
- 4 ads in smaller font
- international publishers ok
- offers additional tools & services
- more competition for higest paying
- multiple ad units per page
- "smart pricing" (CTR taken into account in pricing)

with YPN:
- 3 ads in a much larger font
- beta for US publishers
- only traditional ad units
- fewer publishers means less competition
- same ads on multiple units
- no smart pricing
- in future will be able to transfer your earnings to your advertising account

Many alternatives to AdSense and YPN:
- Kanoodle brightads: avg $0.35 earnings per click (EPC). 30,000 advertisers in network.
- Adsonar: thousands of advertisers
- Clicksor: avg $0.20 EPC. 4,000 advertisers running 20,000 campaigns. Will pull ads from other ad networks if insufficient clicks.
- Chitika: avg EPC $0.50
- Mirago: avg EPC .21p (approx $0.31 USD). you must invoice them. 12,000 advertisers
- ContextWeb: over 40,000 advertisers
bidclix: avg EPC 0.30. 11,000 advertisers
- Others include Miva Adrevenue xpress, Quigo, etc.
Rhetorical question from Jen: "When will MSN jump in?"

Optimizing tips:
- Placement: Bottom of page is bad. Good practice is to make link color the same as other links on the site. Anther good tactic is to place the ads on the left column where the nav usually is.
- Proximity:
- Ad unit selection: Try a variety of sizes and test.
- Ad unit colors & borders: Don't use the standard ad unit colors / layout. Mix things up to prevent banner blindness. Try both complimentary and contrasting colors. Most sites find hidden borders yield highest CTR. like 2 or 3 times
- URL filters: Don't do it as a way to get higher paying ads to appear. Only block your direct competitors or your own websites.

Testing:
- Use AdSense or YPN channels to track highest CTR & earnings pages. AdSense or YPN may perform better. Try both.
- Test on non-holiday weeks
- Try switching ad placement, ad unit sizes and colors
- Keep track of what works and what doesn't
- Never assume that what works on one site will work on another.

Google's contextual advertising technology that they picked up with the Applied Semantics acquisition isn't flawless. It's not always in the best light that your brand gets displayed within sites subscribing to the Google AdSense program. Take for instance the case where a web page featuring a story about a hacked up body in a suitcase displays a Google AdWords ad for luggage, as described in this Fast Company article. Or the also embarrassing but less gruesome example I came across on Robin Good's website recently, as shown below:

Bottom-feeding email marketing solution, anyone? ;-)
