What is Time to First Byte (TTFB)?
TTFB measures the duration from the user's browser sending an HTTP request until receiving the first byte of data from the web server. Google considers TTFB under 200ms ideal.
How does page response speed affect conversions?
Studies show that each additional 100ms of latency drops conversion rates by up to 7%. Fast servers keep bounce rates low and engagement high.
