Slow Time to First Byte

All HTML pages with a 200 HTTP status code and a Time to First Byte (TTFB) slower than 600 milliseconds (Google recommends TTFB of 200 ms or faster).

Priority: Low

Impact: Negative

What issues it may cause

Pages with a high TTFB may cause a poor user-experience and could negatively affect the rankings in search engine results resulting in less traffic and conversions.

A very high TTFB may cause Search Engines to stop crawling and indexing your pages.

How do you fix it

The pages should be investigated using tools tools like PageSpeed Insights to identify the issues that may be causing them to have a high TTFB.

What is the positive impact

Lowering the TTFB may;

  • provide a better user-experience that could positively affect conversion rates.
  • result in higher rankings in search results leading to an increase in traffic and conversions.
  • increase crawl rate of search engines which could result in your pages being discovered faster and updated more frequently.
