> Google Search doesn't have a network effect. Everyone on HN has been saying Google Search is complete garbage for a decade. It still has the same market share (roughly) as it did a decade ago.

It absolutely does. People use Google for search -> Websites optimise for Google -> People get “better” results when searching with Google.

The fact that it’s market share is sticky and not responding quickly to change in quality is sort of indicative of the network effect.
