  • Horribly bad

    horribly bad, you can't change any settings until you pay a subscription! don't waste your time

  • Spam footer link

    The plugin is successful in terms of optimization, but it automatically added a footer link without my consent. I thought it was spam, but I realized it wasn't. You can remove it in advanced settings.

  • real improvement

    I was concerned about load speed for my pages and did a Google page speed and found that my desktop was around 70 and mobile around 55. I installed this package and I saw significant improvement immediately to 98 desk and 70 mobile. Tony Johnson ooftsauce.com

  • Broke my site to force me to get a licence

    This plugin completely broke my mobile site - the reason? They wanted me to get a free licence. I'm happy to get a licence and pay for it - but messing with my website is not the best way to incentivize me.
