You might have noticed that Yahoo Boss made its way into the feature article for February in a sidebar on site search options. If you're unfamiliar with Boss, it enables developers to use Web results from Yahoo's main search index within their own apps.
But as you've probably come to understand, technology moves fast. Yahoo this week announced several changes to its Boss and Search Monkey services. The search service was previously free and will remain so for those generating fewer than 10,000 queries per day, but after that, Yahoo will use a pricing model known as tiered pricing or "buckets" using much the same model as phone and energy companies of old.
Yahoo will begin charging for the service in the second quarter of 2009. Learn about the new open monetization, pricing, structured data and more at the Yahoo! Search Blog or review the Website Magazine article on the many flavors of site search.
