How to Use Website Traffic to Find Your Best Customers

The most visited websites in the world are—of course—well-known websites for most of us. In the Top 10, we find websites such as Google, Youtube, Netflix, Facebook, and Baidu. No surprises there.

Comparatively, the Top 10 most visited websites in specific categories such as SaaS, FinTech, E-Learning, and Cryptocurrency, or the most common CMS, Analytics, and E-Commerce technologies used by the world’s most popular websites are probably less well known for most of us. However, that needn't be the case. This kind of specific information doesn’t have to be less well-known or harder to get a hold of.

In fact, we’ve recently added data concerning the 7 million most visited websites in the world to our company database, which makes it easy to get a hold of this kind of detailed website information. This dataset, combined with our proprietary industry data, allows for the effective analysis of website popularity across many different sectors. Let’s take a look.

Most popular websites by industry

Most popular website technologies

We also decided to analyze the Top 50,000 websites to see which web technologies they were using. Most websites require quite a few pieces of software to work properly. There is of course the CMS platform the website is built on. These websites generally also have some kind of analytics software connected. Additionally, they often link to social media platforms, and many of them include embedded content from other sites. Thousands of websites are built for selling products and goods, so e-commerce software plays a big role, just like different payment methods.

For companies selling anything website-related, understanding website popularity gives a good starting point for allocating scarce resources. Whether you’re selling analytics, optimization, conversion improvements, e-commerce logistics, website chat, site plugins, or e-commerce toolkit, you want to target the segment that will be the most fruitful for you.


Unsurprisingly, Google is the number one technology vendor among the world’s most popular websites. They have several tools that many of the websites use, such as Google Analytics and Ads. Adobe is also one of the most frequently used technologies: We detected that ~10% of the websites are using one of Adobe’s products.


WordPress is the leading provider of CMS, with one out of ten of these websites being built on WordPress. There are also a lot of Drupal sites, and, interestingly, quite a few sites built on, which is typically seen as a solution for small and medium businesses.


These sites also invest heavily in understanding their users and traffic. Hotjar is used by more than a thousand sites, and Optimizely and Segment Mixpanel are tracking data for hundreds of these sites. Search engine optimization is important, too. There are many specific vendors—such as Ahrefs and Yoast SEO—that are widely used.

Embedded content

YouTube also features heavily on these websites, with 11.5% of them having embedded Youtube videos. There are also hundreds of websites using Wistia for the same use case.

E-Commerce & Payment

Shopify is the most popular e-Commerce platform, another popular one is Magento. These sites provide a variety of payment options. Mastercard is the most popular one with 4.4 % of the top websites using it as a payment option. It’s followed by American Express, Visa, and Stripe.


One of the most well-known enterprise software vendors is Salesforce. Based on our data, roughly 5% of these sites use Salesforce CRM. In this segment, it’s more popular than HubSpot, which has a bit more than 1% market share in this category.

Other popular technologies used by these sites are:

  • Slack ~10% (team collaboration)
  • Mailchimp 4.5% (email marketing)
  • New relic 4.3% (site performance)
  • Atlassian 3.8% (productivity)
  • Zendesk 2.9% (support and customer service)

Importance of website traffic for sales and marketing professionals

In this post, we have shared some insights on the most popular websites in the world. This analysis used the Top 50,000 websites in the world as its sample, but in total, we have more than 40,000,000 (that’s 40 million) websites in our database. You might be wondering how  this data would be of help to you, so here's a tangible use case: 

It is quite common for analytics, optimization, and intent data tools to bill their customers based on website traffic directly (sessions) or indirectly (conversions). If that's the case, why should such companies use revenue or employee count as a size indicator in the segmentation process when website traffic could be used instead? More traffic, more potential billing. Such companies could then combine this with accurate industries based on website content (e.g. SaaS, Fintech, Fashion), and web technologies (e.g. prospects using competing or complementing technology) and get refined target segments, e.g. SaaS companies with high website traffic using a competing analytics tool.
