New fresh email or Aged email ?

Hello BHW after surfing on BHW.
I think here what i found ( correct me if wrong )

1.
its better to use aged gmail account than new fresh account.
Q : are all aged email ready to use ? Or need warmup ? Like create channel youtube or do something on that email ?

2.
always using anti detect browser

3.
To make ads (niche) make a campaign to safe page first and do cloacking (must)

4.
Q: how about keyword ? How to findout wich keyword is eligible ?. Im using ahref to crawling my competitor Keyword, but doesnt find out anything. Ahref only show their Whitehat keyword.

example : the keyword is slot online
After search on google page . Google showedup some ads i copy that link and paste on ahref only showing like
