Rainbow, I take it your approach is just acknowledging the problem, but nobody has really come up with ways to circumvent it entirely.
i am not a coder so i cant really apply a solution per-say
knowing the paid content spammers also game the big corps to deliver faked/dominant numerical results lists.
what i wonder is if the hot-word type search result is forced via content results which is able to be scammed to push fake returns.
(fake returns by virtue of true data intent)
clients want total management, but consumers want group experience
i dont have any real answers to this.
what i notice is the expansion of individual units(cell phones & tablets)
which changes the distribution process and changes hit counting(pay per click)
while the individual value of a click has dropped significantly, the potential link to other networks by tracking cookies and data mining is extensive.
2 things atmospherically strike me
1 the new era cold war type issues between sovereign nations seeking to nationalize and protect their own consumer markets.
2 the ultra nationalization trend that is almost a retreat of interactive association(this will skew data)
meanwhile the machine of profit just hunts clicks n trends for as much access as possible.
you cant fight the system and reward yourself with it without massive processing control which might be potential self filtering(servers searching and then filtering to pre chosen result values).
google is like dipping your toe in the community pool that may be filled with human waste , or perfectly clean.
im not sure AI can define a difference
i would simply block amazon outright and all servers running shopping data bases.
the use of them excluded would show enough of a gap to elucidate any required alternate value search i would guess.
thats my casual laymens opinion
...i would term this "intuitive searching" where you have a pre chosen set rule of valued results.
results are then processed.
blocking primary channels can give a much smaller yet vastly more accurate result.
however, doing this would face you off directly against paid coders seeking to exploit those avenues to remove them.
