Banned by google??

Hello,I want to ask.

i have a new domain, and i link that new domain with blog with PR5. In 24 hour, my new domain indexed by google. But the next 2 days, my new domain not indexed again in google. Is my new domain banned by google or do you have an experience with case like this...???

Please share with me.

Not an expert but if you honestly did exactly what you said you should not have been deindexed by google or "banned" as you put it. Since it is a new site it will appear and disappear at Google's whim so don't pay much attention to it.

Keep working and developing the site and it will get back there or even higher.

its not deindexed dear, it happens for new domains
it will show up again soon
