Introduction
If you’re like me, you use Google every day to find things—news, technical support,
events, tips, research documents, and more. Were you to master Google’s powerful
search refinement operators and lesser-known features, over a year’s time you could
save days scouring over irrelevant results.
Perhaps even more enticing is the promise of elusive nuggets of market research and
competitive intelligence out there waiting to be discovered. This book will show you
how to find what you need quickly and accurately.
With over a trillion URLs in its index, Google is a veritable treasure trove of information.
Yet finding just the right document out of this mass of URLs—the one that answers
your question—can be daunting. There’s good news for you, however. The search
results you seek are about to rise to the top of the results, thanks to some of Google’s
search-refinement operators that I’ll talk about in Chapter 1.
In Chapter 2, I’ll introduce you to the world of Google’s advanced search operators,
such as filetype:, intitle:, inurl: site:, and daterange:. In Chapter 3, we will put our new
search refinement tools into practice with a real-world example. We will also address
various features available from Google’s interface, such as Search Within Results, Sim-
ilar Pages, SafeSearch filtering, spelling corrections, “I’m Feeling Lucky,” and the Ad-
vanced Search page.
Chapter 4 will cover Google’s many other search properties, including iGoogle, Google
Reader, Google News, Google Maps, Google Product Search, Google Groups, and
Google Images, as well as some useful third-party sites powered by Google.
In Chapter 5, three more Google gurus will weigh in with their opinions on the best
time-saving search strategies, query operators, Google sites, and more!
In Chapter 6, we will discuss some tools, operators, and tips that are particularly useful
to Search Engine Optimization (SEO) professionals in their quest for higher Google
rankings for their websites.
