Now does that translate into something like "comparative quality" within a niche?
This would logically have to be true. But it appears Google is acting illogically, which makes it so difficult to second guess.
The websites in my niche are download sites (galleries). 99% of them don't bother to add any textual content and still manage to receive masses of traffic. The largest receiving 400,000 visitors per day and has no textual content on most of their pages.
I've spent tens of hours, writing textual content for the pages and to absolutely no effect. Zero.
