You can get great insights to optimize your website by using Google Analytics. It's a free tool to track most of the important metrics to evaluate the performance of your website. There is one major flaw in Google Analytics (or most other web analytics tools). It doesn't allow you to get qualitative feedback from your users. Most web analytics tools don't allow you to ask your users what they think when they are visiting your website.
We believe listening to your visitors can get you the best insights to optimize your website and help your users have a pleasant time on your website. That's why we developed a plugin which allows you to get this qualitative feedback from users. Once you setup the plugin to your personal needs, you can find the feedback of users in your Google Analytics account. You can see an example of our Google Analytics feedback extension in action on our website. Just take a look in the right bottom corner of this page to find our little button.
