I like that it is easy to use for my clients who are not tech savvy at all! It also makes me look good because they can see how much faster their site loads up compared to other competitors in our industry (real estate). Sometimes when you have multiple plugins installed, some of them don't work well together so sometimes there will be errors or popups but this isn't always an issue. We've noticed increased traffic from Google search results as well which has been great since now more people know about us through organic searches than paid ads.
