Are Weblogs (blogs) included in Google search results?

Hello. 

It depends.  Many hosts (like Xanga and Blogger) have no option to
block searching, and are fully indexed on Google.  For instance if one
searches for a random word like "orange" and limits the results by
using the term "site:xanga.com" or "site:blogspot.com" one gets these
results respectively:
://www.google.com/search?q=site:xanga.com+orange&ie=UTF-8&oe=UTF-8
://www.google.com/search?q=site:blogspot.com+orange&ie=UTF-8&oe=UTF-8

However, LiveJournal and hosts that use its code (like Blurty,
Deadjournal, and uJournal) have an option to "Block Robots/Spiders
from indexing your journal."  Google is among the search engines whose
spiders respect this rule.

Also if you are hosting on your own server, you can set up your own
robots.txt file which can block robots from indexing parts (or all) of
your blog.
