Assume I got an Adsense account with an 1-year-old site, now I set up a new site, can I put the ad on it immediately? Or should I wait for 6 month till the site old enough? Need help. Any suggestions and comments are appreciated.
You don't need to wait so much. You can place whenever you want, but without content, google don't shows ads .
just make sure the new site has plenty of content and ensure it is "family friendly" and complies with adsense TOS.
There is no problem with placing adsense on new sites (thats why therei s adsense for domains program) with no content at all. You can specify the hints and adsense ads will still show even if there is no content. But if it lies there without content for many weeks and google notices many suspicious click thrus then account willg et banned
I believe there is no problem adding banners to your site if its new, just add a little content here and there then youll be fine.
When I showed my site to google adsense it had very little content that it often didn't even show ads on many pages. But the thing is they accepted me. The site was totally new. No traffic.
Of course, but it would be good that your site satisies base google reqirements for adSense publishers sites.
