Thank you for clarifying that. I personally feel that intentionally using bots is a very wrong step. But sometimes to save our profile and to satisfy our client we have to take this step. We don’t have any choice left when the clients forced us to achieve maximum results on Google Pagespeed Insights. We told our clients several times that this is the maximum speed we can achieve but they compare the results of other stores and it leaves us speechless. My final conclusion is that 70% is the real speed optimization and the remaining 30% is what the client wants to see on Google Pagespeed Insights.
