Following are the 
websites/blogs that I would recommend to follow to keep yourself updated
 with recent developments in “search” world. You can sign up for email 
updates. List is in order of importance.
SEO

(GWT). Google announces major changes they are bringing in GWT, 
the search engine in general, latest algorithm updates etc. on this 
blog.

YouTube Channel of Google Webmaster-
You can find videos of Matt Cutts
 on this official channel of GWT. He answers queries in these videos 
which are really insightful, but never follow the suggestions blindly 
;). After all, Google is also a commercial organization.
 You can subscribe to the channel.

Moz Blog- They
 are wizards of SEO. They provide really cool SEO, web analytics and 
social media tools like Open Site Explorer, Followerwonk etc. They have 
two separate
 blog sections- one Moz Blog and another YouMoz. On Moz blog, mostly you
 can find posts from Moz employees and on YouMoz from other blog 
members. Nice way to learn new techniques.

 is personal blog (as he promotes, but I don’t think so he manages it 
alone) of entrepreneur Neil Patel, he is CEO of company which provides 
amazing
 analytics tools like kiss metrics and crazy eggs, you can check their 
separate blogs also. On quick sprout most of the times he shares very 
genuine and out of the box tips for SEO with links to useful resources.
