Somewhat old news, and I'm sure many of you have heard this by now (I think ThomasHarvey might have mentioned it in a post somewhere!)...
But Google released all 160 sweet pages of its Search Quality Raters guideline and handbook.
The big, fat ol' handbook can be found in all of its .pdf glory here.
What's getting the most press right now, I think, is the big "Part 3" of the guidelines which is titled "Needs Met Rating Guideline." Part 2 is also about a very popular topic: "Understanding Mobile User Needs."
Important to note is that this guidebook is used (as I understand it) by Search quality evaluators. The intro reads:
When I have time, I will try to skim through these pages for interesting snippets. If anyone else is bold enough to join me, please post your own snippets for discussion too!
Or post your general thoughts, criticisms, and comments. Just don't spam ;)
I'll make this a sticky thread for now, since I think it's a big news item. It may be unstickied at a later date.
