Alexa provides a whole host of tools that help website owners gauge how well their sites are doing. They provide tips on improving SEO, PPC, and ideas on how to grow your website traffic in the long run. One of Alexa’s most well-known features is its ability to rank websites based on their web traffic. You can type in any website into the search bar and get a rank, both in the United States and worldwide. You can sign up for a trial that lasts a week, but will have to pay to really take advantage of the website in full.
