This is by far one of the most valuable articles we've released. Written by Ann Smarty (an SEOmoz member/YOUmoz author and blogger for Search Engine Journal), the guide provides some fantastic charts that detail each engine's various search operators and compares them across the board. I've shared the Table of Contents below to get you an idea of what exactly the article encompasses:

1. Introduction: Who is This Guide For?
2. How & When to Employ Tools, Queries & Web Services
3. Valuable Web-Based Tools for SEOs
4. Advanced Search Queries
   • Google Queries
   • Yahoo! Queries
   • MSN/Live Queries
   • Comparison of Advanced Search Operators Across Google, Yahoo! and MSN
   • Other Engines & Query Sources
5. Valuable Search-Related Services on the Web
6. Closing: Employing Queries, Services & Tools for Direct ROI

Like our recently released Professional's Guide to Blogging, The Professional's Guide to Advanced Search Operators costs $39 + tax to purchase from our store. If you want to purchase both guides, you'd have to dish out $78 for both of them...or you could pay $49.99 for a monthly SEOmoz PRO membership, which grants you access to all of our PRO guides as well as premium access to our suite of tools (such as our new Trifecta tool and our SEO Analytics). If you're thinking of purchasing both articles, I highly recommend trying out SEOmoz PRO for a month--it's a better value than buying the guides individually, plus you get access to tons of extra goodies.

• Purchase a PRO membership
• Individually purchase The Professional's Guide to Advanced Search Operators

Already a PRO member? Fantastic--you should be reading this guide already! Ann did a wonderful job putting it together, and it is bursting with incredibly valuable information. Take advantage of your membership and check it out at no extra cost.
