I modified a site recently : - I added many google analytics events, to better understand user behaviour. - I added also two buttons on almost all the pages of the site. Those buttons show modal-views (I am using bootstrap) with questions about user opinion. This modals views are on almost all pages of the site.
After this modification the ranking of the site decreased on google search from the second place to the seconde page :(
Is it the events-collected or the model-views added ? If the model-views are the reason, then how to better do similar surveys ?
Did you have please similar experience, or explanation to this ?
