Does Delaying Ad Loading for Speed Reduce Revenue?

[jaypanda]

Hello friends. I have a website that covers TV series news with 1k hits. My site's speed tests were excellent on both mobile and desktop. The Webmaster Tools also show that everything is green. However, Adsense ads are taking two to three seconds to load on the site, resulting in a low click-through rate of 1%. To address this, I added a code to delay the ads from loading. 95% of my traffic comes from mobile and is organic. There is a lack of effective Blogger Adsense ad placements, and I am seeking suggestions on improving revenue on mobile. My questions are:
1. Does the speed affect the click-through rate?
2. How can I optimize for better earnings on mobile?
I look forward to hearing suggestions from those who have ideas. Thank you. Site Address.
