He guaranteed results and he delivered! He also provided some very useful advice that I used to further improve loading time, including adding free caching plugins, and critically resizing and smushing images. Average performance scores on PageSpeed Insights have increased from the 30-40% to 90% for both desk top and mobile. When tested on "Lab" basis both are 98-100%. Loading times of 1.5 sec and less. Note the provider knows what he is doing, and is responsive to questions. All in all a good experience. The best $100 I have spent for website improvement.
