Ought to I wait to use for AdSense?

I’ve by no means used any adverts on my web sites, so earlier than beginning utilizing platformas like Ezoic (which most of you assume is healthier than adsense however can decelerate your website), I want to see what occurs utilizing vanilla adsense.

Since web site B is my “good web site”, earlier than making use of with it, I attempted with my very first web site A (a really noobish one) however it acquired rejected for “low worth content material”.
That is actually comprehensible since this outdated web site A get round 1k visits per thirty days however it isn’t very properly structured and It solely had about 3 pages and 12 posts (plus all privateness, about us pages).
Aso I’ve not up to date it in months.

I am now questioning what to do:
is there any probability that making use of too early with my good web site B for adsense might have some sort of adverse penalties on it? Would failing one time make it tougher to have success sooner or later? Ought to I simply go for it or wait? (notice that web site B has 47 good articles so I feel it ought to get accredited)

Different factor i can do is attempt to make the dangerous outdated web site A good for adsense by restructuring it, making it look higher and including content material, however that will clearly require effort and time that I’d slightly spend on different web sites.
