hello , i've just created a new blog , and i would like to know if i'll have to create another adsense account or i'll have to add my new website in the same adsence account ,with the first one
Well, there is no need to create a new adsense account. You can use that one adsense account for all your blogs and sites. - Digital -
No need to create a new adsense account. If you want to track the performance of individual sites, you can use channels in adsense.
don't create another account. it violate the adsence policy. add a new channel and put ads from that channel
