Well whatever the cause, SEO spam means that searching for anything generally popular returns pages and pages of results to sites with low depth content and no real substance.
I realized this when I was curious to know when a TV show’s next season may start and all the search results were useless fluff articles, even though their titles looked promising.
In conjunction with my having concluded some time prior that they had generally switched their search (for example when searching for software development stuff) to seemingly always assume I was actually searching for something else, made me convinced that Google had become quite useless.
