How Many Websites Are There In The World?

The Internet is BIG! Very big. However it is dominated by just a few hundred organisations and their websites. So how big is the Internet? How many websites are there? According to the Netcraft January 2019 Web Server Survey there are 1,518,207,412 (over 1.5 billion) websites. Yes, the Internet is very big. However, most of those websites get almost no visitors.

(This post first appeared in January 2014 and has been updated yearly.)

World Wide Web

How Many Websites Are Active?

The size of the Internet can be measured in various ways, including totals such as: How many websites are there? How many domains are registered? How many websites are being used? What are the most popular web sites? How much storage is required to hold all the web data? How much data is transmitted? Etc., etc. The trouble is the Internet is so big that these totals and numbers change all the time. For this brief look at the size of the Internet the total number of websites is examined. In other words you can type a unique domain name into your browser’s address bar and you will get a response.

The January 2019 Netcraft Survey shows a significant fall compared to last years number:

A Yearly Table of the Number of Websites in the World

Month and Year Number of Websites
January 2019 1,518,207,412
January 2018 1,805,260,010
January 2017 1,800,047,111
January 2016 906,616,188
January 2015 876,812,666
January 2014 861,379,152

When this article was first written in 2014 it used the Netcraft January 2014 Web Server Survey. Then there were 861,379,152 websites. During 2014 the total number of websites exceeded 1 billion for the first time (in September). The number of web sites peaked at 1,028,932,208 in October 2014 before falling back below 900 million. Had the world enough web sites at that time? Especially as mobile phone apps have become so popular as a way of accessing Internet services.

Despite the number of websites staying below a billion for a while, the peak had not been reached. It was not until March 2016 that the billion website mark was broken again, at 1,003,887,790 sites. This time not falling back. Indeed 2016 saw big growths in websites with Microsoft being the big winner. Their web server platforms and Azure cloud offering had seemed to hit all the right notes. However, as with all things in computing nothing lasts for ever, and the NGINX web server began gaining popularity.

Website numbers kept growing before peaking at 1,838,596,056 sites in February 2018. Since then website numbers have fallen, down to October 2016 levels.

What is the Total Number of Domains in the World?

Those of you that don’t understand the workings of the Internet may not realise that the 1.5 billion plus website number is just over three times larger than the number of registered domains. Why?

According to the Verisign Domain Name Industry Brief the total number of registered domain names in Q1 2019 was 351.4 million. So more than 351 million domains support over 1.5 billion websites. But not all registered domains get used. Some are just registered so that no one else can register them. Some are registered and never used.

When this post was first written in January 2014 the ZMap project, a high speed open source network scanner, had scanned the entire Internet and estimated the total number of hosts at 108 million. Then it was likely that the then 861 million websites were active on 108 million hosts. This is because a domain can be divided into sub-domains. For example a blogging website, such as Blogger, WordPress or Ghost, will let a user create a website that hangs of the main domain name, e.g. https://blog.wordpress.com/.

The January 2019 Netcraft Survey reports 8.2 million (8,209,715) web facing computers. So 8.2 million computers serve up 1.5 billion web sites. Most of these sites are static and hardly change. Netcraft estimates that there are 182 million active sites (those that get regular changes). The number of active sites has increased from 172 million in 2018. Despite the huge number of websites less than 10% contribute fresh information to the Internet. That is a lot of underutilized resources and thus wasted money.

A Few Hundred Sites Dominate the Internet

Despite there being over 1.5 billion websites only a few hundred dominate the Internet. Less than 1 million, or 0.1%, account for over 50% of web traffic. To get an idea on how much such a small percentage of the total websites dominate look at The Internet Map.

Summary for How Many Websites Are There

As of January 2019:

  • There are 351 million registered domains...
  • for over 1.5 billion websites...
  • served up by 8.2 million computers.

With 1.5 billion websites, if you publish a website it is very unlikely it will get noticed... Unless you are prepared to produce quality content, perform Search Engine Optimisation (SEO) and spend on marketing. Or you may get lucky, and be the next big thing, as all the top sites were once.

Thomas on April 23, 2017 at 4:26 pm said: The internet is too flooded with websites and many people are sick of it, bottom line with the gigagiants taking over the little guy has no chance.

Tek Eye on April 23, 2017 at 11:19 pm said: The gigagiants won along time ago. But the world is big enough for niche websites. Find your passion and produce good content, keep producing content to fill the niche. Meet the needs of a target audience and promote it on social media. If you get to 50,000+ page views per month you are in the top 0.1% of world websites. 99.9% of websites get almost no traffic. Even the gigagiants started out with no traffic, but they found an idea that worked.
