Aaseesh from Google responded to a complaint about Google not picking up on a web site’s canonical tags. He said that “even if you setup the canonical tags properly, other signals like inconsistent redirects can make Google not select your preferred URL”. As you know, Search Engine Land was delisted from Google’s search results for most of the day on Friday because a bug in Google’s hack sites classifier labeled the site as being hacked. Colin McDermott ran a Twitter poll asking if Google should delist the site or just issue a warning. 2/3rds of those who responded said Google should just issue a warning. DuckDuckGo, a Google competitor, came out with a study that claimed Google’s search results create what is known as a “filter bubble,” this influencing what you click on and see. Google came to Twitter and defended themselves saying their personalization does not do that.
