Context
Consumer and prosumer web apps, aggregated A/B summaries
What changes
Social login reduces typing, password friction, and drop-off on the first screen.
Caveats
- B2B buyers may prefer work email over personal OAuth
- Apple/Google button placement and default selection matter
- Privacy copy must be clear or trust drops
Practical takeaway
Run an A/B test on your top landing page. +8%p is a useful hypothesis, not a promise.
