I have the same problem. The readme file states:
“1. Upload the whole plugin folder to your /wp-content/plugins/ folder.
2. Go to the ‘Plugins’ page in the menu and activate the plugin.
3. Use the ‘Options’ page to change your plugin options.
4. If you want to use Google Maps module then get your free Google Maps key here: https://code.google.com/apis/maps/signup.html
5. Write a new post. You will notice Insights toolbar. Use it :)”
However, I am unable to find the “options” page.
Any ideas?
