Why does speed matter?

Search engines like Google, measure and factor in the speed of websites in their ranking algorithm. When they recommend
a site they want to make sure users find what they’re looking for quickly. So in effect you and Google should have the
same objective.

Speed is among the most significant success factors websites face. In fact, your site’s speed directly affects your
income (revenue) — it’s a fact.

Speed it’s a game changer in visibility, and some consequences of poor performance are:

  • Lower perceived credibility and quality
  • Increased user frustration
  • Reduced conversion rates
  • Increased exit rates
  • Are perceived as less interesting or attractive

What to do if I run in some issues after upgrade?

Deactivate the plugin and reactivate it, if this doesn’t work try to uninstall and reinstall it. That should
work! Otherwise, go to the new added module “Setting” and try a reset.
