Excerpt from SEO Book worth reading - Thank you Aaron:

"While Microsoft is busy fighting off competitors in many markets, Google keeps gaining market-share and market leverage in new verticals through soft-bundling.

One of my clients that did not use Google Checkout simply had to stop advertising on AdWords until Checkout was enabled, because without it the usually slim profit margins on AdWords turned negative. It turns out that pricing ads based on "quality" with a discount for a higher clickthrough rates allows the highest quality advertiser to rank #1, so long as they are using Google Checkout to give Google more market data and another chance at monetization. ;)

The Google Chrome browser is recommended on Youtube, advertised all over the AdSense network, and pushed via bundling partnerships with the likes of the Real player and Divx. Its release forced Microsoft to make some of their security products free, and will keep costing both companies money, with the hope that it costs Microsoft more than it costs Google.

Google is still crying to the EU that Microsoft's business behaviors are uncompetitive. Once you get branded it is hard to get un-branded. In spite of the recent slowdown in search volume Google still has a lot of market momentum behind them. You will know Google is in trouble when the market stops giving them leeway and treats them more like Microsoft.
How You Can Apply This to Your Business Today

1.) Always push to own a market default position and once you achieve that position keep investing in maintaining it, while reminding the market that your growth was organic due to your superior quality.

2.) Even if the business model is not there you can always create one/bolt one on if you get enough exposure. In the age of soft bundling it is no accident that we offer some of the best free distributed SEO tools like the SEO Toolbar and SEO 4 Firefox, with intent of helping push this site into a default market status.
