Okay. Maybe I am late to the party on this, but I didn't find anyone else writing about it. If there is, please comment and add a link below. Let's give credit where credit is due.
I was doing research to see if anyone had written about something a bit absurd I read on a dot gov blog. Indeed people had. One place I found this topic I was researching was at Breitbart.com.
If I were to use the results of just one search to besmirch a search engine would be wrong. However, Google can crawl a site per keyword protocol. So let us try a keyword site protocol. Go to Google and crawl the whole Breitbart.com site with site:breitbart.com. So, as you see, the results are EVERY page is malicious.
Yeah. No search engine bias here. Google couldn't possibly have a liberal bias.
