If you care enought about an industry you are bound to start reading the same comments, stories and hearing the same opinions from every “voice” of that industry.  Cutting the clutter and finding the source of all the news is ultimately the best way to get the facts straight.  One of the best ways is to read the Search Engine blogs themselves.  Here are the major ones you should be keeping up on:

Yahoo Search Blog – The official Yahoo search blog is the source for all things Yahoo and is updated regularly by the folks at Yahoo

Google Blog – This is the official Google blog and covers all things from Google.  There are other Google blogs maintained by particular departments and I’ll go over the ones I care about.

Adwords Blog – This is the source of all things Google Adwords and where most of the AdWords announcements, tutorials, trainings and unveilings happen.

Google Analytics Blog – This is for when you think you know enough about Analytics and need to be reminded there’s another layer:)

Live Search Blog – Always nice to mention something from Microsoft when talking about search marketing…rarely insightful but always good.

Hopefully this is helpful in getting you closer to the source of search engine news.
