Website Competitor Analysis Tools
While there are many tools that monitor website changes, there are only a few that do this exclusively. These tools will track everything from what code tools they're using behind the scenes (CMS, JS libraries, CDNs, etc) to visual changes on the site like new headlines, graphics, or overall website design changes. Depending the changes you're hoping to track on your competitors' websites, some services will allow you to receive alerts when these changes take place. This collection includes 6 tools.
