I just ran G PageSpeed test on a site of mine that only runs AdSense
so I was a bit surprised when GPgSpd reported that I should compress the following:
Compressing https://cdn.spotad.co/sg_general/0.0.105/sg_ad_manager.min.js could save 24.7KiB (68% reduction).
I'm not an AdSense expert so I don't know if G mixes things up. I'm not running any other ad feeds or alternate ads.
I have alarms going off, wondering if my site has been "jacked", i.e., someone other than my friend Google has managed to inject ads. I searched G for SpotAds.com + AdSense and nothing popped up that would explain a connection.
