Because the results of the different search engines might have been influenced by the searches I did previously, I asked an old friend who lived in Canada to do the same searches for me with the different search engines.
And the results were the same for Bing, Yahoo, DuckDuckGo, Web crawler, Yippy, Oscobo and Dogpile: on PAGE ONE!
For Google it was a bit disappointing: high on PAGE 5. Affected by my previous searches? Local influence? More competition in Canada on this topic?
