Alexa Browser Extension For Chrome & Firefox
For the last 20 years or so Alexa has been owned by Amazon. The system has, however, been around for longer than that and is well-known for its web traffic and analytics platform that enables digital marketers to find useful data about their own site, or their competitors site, and how they are performing.
Now, with the free Alexa browser extension, which is available for Chrome and Firefox, you can see at-a-glance how the website you are viewing is performing.
When you are putting together your digital marketing strategy you are going to need services like those offered by Alexa and their full service offering is reviewed here but for many users, the free browser extension could be an ideal place to start and maybe all you actually need.
