Here's a tip.
If there's a blog you like to read, go read the archives. Or if there's a specific subject you'd like to read about, you can do a site-specific search on Google designed to get the results that you want. For instance, in the Google search field enter this:
site:michelfortin.com split test
This is what I just entered. I read a few of the articles and found exactly what I was looking for. I also found some good stuff I wasn't looking for... like this article on split-testing. If you have a moment, I highly suggest taking the time to read it.
The formula for site-specific searches on Google is this:
For instance, if you wanted to search my blog for headlines, you would type this:
Enjoy! And don't forget to read Michel's split-testing article. :-)
