How CDNs can help improve Time to First Byte (TTFB)
A couple of months ago we released a post that investigated the relationship between TTFB (Time to First Byte) and CDNs, based on the premise that TTFB is the most SEO-beneficial performance metric.
The goal of that post was to explain that TTFB is just another name for “How quickly can I deliver my HTML files?” and that 9 out of 10 CDNs will not help your HTML delivery, mostly because HTML tends to be dynamically generated and is thus typically uncacheable.
This infographic recaps the main points of that blog post. For more details you can find the full post here.
