An analysis of recent admissions made by Google employees in their official capacities by a search engine optimization (SEO) expert proves that Google CEO Sundar Pichai lied to Congress in 2018 when he testified under oath that it is not possible for Google employees to manipulate their search results. This analysis is backed up by properly cited sources including blog posts written by Google employees in their official capacities, comments they made publicly, and Pichai's testimony itself.
The facts exposed in this analysis lead to one conclusion. That Google has a mechanism in place for suppressing specific sites for specific searches. It involves adding domain names to lists of sites categorized a certain way and then adding search terms to second list. When someone searches for one of the search terms then Google automatically ranks sites on the first list significantly lower.
Google admitted doing this to sites with exploitative removal practices recently and stated in that admission that they had already been doing it to porn sites for some time. Their methods involve soliciting complaints from people claiming to have been victimized, having employees review the complaints, and if the complaints are substantiated they add the name of the complainant to a list of "known victims." When a person is a "known victim" and someone searches for their name then sites on the exploitative practices list rank lower.
This mechanism in which Google employees manually categorize websites and add names to a suppression list is the same type of mechanism needed to suppress conservative sites from appearing in search results for politicians. The only difference is that in such cases the category would be populated with a different type of site (ex: right wing media) and the "known" list would be something like "known Republicans." Then when someone searches for a known Republican like Donald Trump, conservative news sites would be suppressed automatically.
