Classic analysis Dynamic analysis

The classic classic analysis is very fast and efficient, but it does not take into account Javascript and does not produce an audit of network traffic (images, styles, and other scripts loaded with the page). The classic analysis is particularly suitable for HTML/CSS sites or to check your redirections, network errors, etc.

The dynamic analysis audits the DOM of your pages after loading Javascript and all the elements attached to the page (images, scripts, styles). The SEO analysis also focuses on these elements. This is the type of analysis that is closest to the behavior of Google. Longer than the classical analysis, it is particularly adapted to sites developed with a framework Javascript (AngularJS, etc.).
