Tool Claims To Show Google Search Bias

The commenter Yo_its_Me is on the right track. The key issue is not whether or not they can or should do it. The key issue is deception versus accuracy in the adherence to their published definition and public’s understanding of “Search Results”.
If millions if not billions of people believe that Google’s search results are organic, then they should be just that. If the public see an ad and recognise it as an ad. no problem.
If the public see a link to a promoted page and recognise it as a link to a promoted page, again, no problem.
Its when Google elevate a link to a page above its natural ranking and the users cannot obviously see that is the case is where I question the integrity of the process.
I know many people do not even recognise the paid ads at the top of the organic search results as ads.
