Anyone have more detailed resources about those tips?
Thank you, Alan.
Please why is my articles disappearing and reappearing on Google search results?. Please help.
Is the info starting a 4:55 accurate? I thought top-level origins no longer share caches for sub-resources?
why adsense js make web very long to load ?
@Wix
Horray!
thank you for this video 🙂 there is a typo, at 3:41 – webback
very cool, thanks, Alan.
There are some weird little things that are slightly wrong that I guess the person who wrote this text is not a javascript developer. like webback? treeshaking is a technique to identify unused js? this is clearly nitpicking but hearing that from google sounds really strange.
Ok sir thanks im applying,
JavaScript best programming language
Thanks for the brief info.
When are you going to optimize AdSense JS?
