Yes most of what is on the web is not trustworthy so a Google search will not show trustable sources.

Thus I look at known trustworthy sources e.g. traditional media where their biases are known. Or places like here which get some known reputation.

Reviews long established places like Consumer Reports and Which . Reviews on sites I assume most are false - but I look at negative ones and see if there are some common problems that seem reasonable.

I assume all influencers are liars or at least advertorials.

One good rule is looking how the site/author gets paid for doing what they do. If not obvious assume that it is getting clicks.
