How Do Search Engines Work?

Assume you are reading a book and want to find references toa specific word in the book. What do you do?   You turn the pages to the end and look in the index! You will then locate the word in the index, find the page numbers mentioned there and flip to the corresponding pages.   Search Engines also work in a similar way. Search engines are constantly building and updating their index to the world wide web. They do this by using “spiders” that “crawl” the web and fetch web pages.

Yahoo! switches to Bing search results

Now Your adCenter account is the only one that client will now need to manage client search advertising on Yahoo! Search and Bing search.

At this day is a momentous day for all, as Yahoo! has completed the process of moving search ad serving for Yahoo! to the Microsoft Advertising adCenter platform in the U.S. and Canada. And also this marks the completion of the transition of advertisers’ Yahoo! Search Marketing accounts to adCenter[MSN].

AdCenter advertisers [Client] now have access to 163 million unique searchers and 33.8% of U.S. search queries (source: comScore Core Search (custom) August 2010) on Yahoo! Search, Bing and partner sites, with the convenience of one account.

Here are some important points for advertisers to remember:

Managing adCenter accounts

• Going forward, your adCenter account is the only one that you will need to manage your search advertising on Yahoo! Search and Bing.
• Please make sure that your adCenter budget is large enough to cover your estimated clicks from both search engines.
• Monitor your adCenter results frequently, and be prepared to make adjustments to maintain your ROI, as there may be some initial variability while Yahoo! Search Marketing advertisers are integrated into adCenter.
• Beginning tomorrow, all Yahoo! Search Marketing accounts will change to a read-only state. This means that you can no longer make changes to your Yahoo! Search Marketing account or use it to manage your ads and campaigns; you will need to use your adCenter account to advertise on Yahoo! Search, Bing and our partner sites. Click charges will no longer accrue in your Yahoo! account.
• Your Yahoo! accounts will be accessible for the next five months via the same log-in you have used previously, so that you may view historical data from the past 13 months. You do not need to take any action to close your Yahoo! Account.
