Measured, not guessed
Bundle analysis first, then the changes that the numbers justified: code splitting along real route boundaries, tree shaking, caching strategy, and lazy loading for what genuinely was not needed on first paint.
Why this is SEO work
Page speed is a ranking input and a conversion input at the same time. Most of what gets sold as technical SEO is this: rendering strategy, payload size, and what the crawler can actually see.
Result
Build times fell about 20%; the initial bundle fell about 15%.
