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 immed
