I'm not a Kagi subscriber, but I'll be. Yesterday I was looking for a pdf reader app with a specific feature. Nor Google nor Bing helped me; result pages were almost 100% ads (most by Adobe). I was giving up. My first try with Kagi gave me exactly what I wanted.
Can I guess it wasn't a result of keyword stuffing with every result but Google and Bing "forgot" some of your search terms to show you more thinly veiled ads/"content"?
