Does slow TTFB mean my website is the problem

No. A slow TTFB usually means the server is taking too long to respond. It is normally a hosting or caching issue, not a problem with your content or design.

How does hosting affect TTFB

Cheap or overcrowded hosting slows down your server response time. When too many websites share the same resources, TTFB increases because the server cannot respond quickly.

How does distance from the server change TTFB

If your hosting server is far from the visitor, the request takes longer to travel. For example, a UK hosted site will always give slower TTFB results to visitors in the USA. This is why CDNs help.

Can plugins affect TTFB

Yes. Some plugins force the server to run complex tasks before sending the first byte. Heavy or unoptimised plugins increase TTFB by slowing down server processing time.

Can caching improve TTFB

Yes. Caching allows the server to send a prebuilt version of the page instantly. Without caching, the server rebuilds each page from scratch which increases TTFB.

Does a CDN reduce TTFB

A CDN reduces TTFB by serving the website from a location closer to the visitor. This removes long distance delays and improves TTFB worldwide.

What Is TTFB? And How to Reduce It Fast

Q: What causes a slow TTFB

A slow TTFB is usually caused by server delays. This often comes from slow hosting, long distance between the user and the server, heavy plugins, lack of caching, or no CDN in place.

What does TTFB mean? Well, it stands for Time To First Byte.
It is one of the main metrics in Core Web Vitals.

Updated 28 January 2026

It measures how long it takes for your server to start to respond when someone visits your website.

In simple terms:

A visitor clicks your link
Their browser “knocks” on your server
It is the time it takes for the server to “open the door” and send the first piece of information.

A fast TTFB makes your whole website feel faster.

Why It Matters for Speed and SEO

TTFB is the foundation of website speed.
If this first step is slow, the entire page feels slow, no matter how well optimised the rest of the page is.

A good TTFB helps with:

Better user experience
Stronger PageSpeed Insights scores
Faster loading on mobile
Better Core Web Vitals performance
Higher Google rankings

Google prefers sites that respond quickly, because fast response times are better for visitors.

What Is a Good TTFB in 2025?

Here are the easy numbers anyone can understand:

Good: under 200 ms
OK: 200 to 500 ms
Slow: 500 ms to 1 second
Very slow: over 1 second

If above 500 ms, you are losing speed before the page even starts to load.

What Causes a Slow TTFB

A slow time usually comes from server problems, not your website itself.
Here are the most common reasons:

1. Slow or overcrowded hosting

Cheap hosting often means your site shares resources with many other customers.
When the server is busy, TTFB increases.

2. Long distance between the user and the server

If your website is hosted in the UK but someone visits from the USA, the request takes longer.
Distance affects TTFB.

3. Heavy or unoptimised plugins

Some WordPress plugins force the server to run complex tasks before sending the first byte.

4. Lack of caching

Without caching, the server must rebuild each page from scratch.
Caching creates an instant copy that loads immediately.

5. No CDN

A CDN makes your site load from a location closer to each visitor.
Without it, TTFB is slower worldwide.

How To Fix TTFB Quickly

Improving it is one of the easiest and fastest wins in speed optimisation.

• Remove slow plugins

If a plugin delays the server response, replacing it often improves the issue straight away.

• Enable CDN support

A CDN reduces the physical distance between the user and your server, which lowers TTFB globally.

• Optimise your WordPress setup

Lightweight themes and careful plugin selection will keep the server’s workload to a minimum.
