How does Redis improve SEO?

Redis reduces TTFB by serving cached content instantly. Faster response times improve Core Web Vitals and user experience, both ranking factors.

What should I cache with Redis?

Cache rendered HTML, API responses, database query results, session data, and computed values that are expensive to generate.

How do I handle cache invalidation?

Use time-based expiration (TTL), event-based invalidation on updates, or cache tags for granular control.

What it does

Redis is an in-memory data store used for caching frequently accessed data. It reduces database queries and computation, delivering content faster.

Why it matters

Fast TTFB improves user experience and SEO rankings. Redis caching can reduce response times from hundreds of milliseconds to single digits.
