Did you ever wonder which websites were the most popular, and how many visitors they receive? The table to the right lists the top ten visited websites during the month of September 2016 according to Quantcast.

Quantcast lists more than just the top 10 sites (I searched for websites around the rank 10,000 and Quantcast was still showing results). Knowing the top websites can help marketing efforts in the following areas:
- Website Visibility: identify the most popular search engines and directories, and ensure your website is visible on those sites through listings, rankings, and advertising.
- Social Media: focus on reaching new clients or retaining existing ones by setting up social profiles on the most popular social media sites.
- E-commerce: sell your products and services in the most popular markets and channels.

In addition to Quantcast, Alexa and SimilarWeb also provide top website lists.
