I run several ads on Google adwords ,but these days some of my product domains are getting banned so I just need to ask that will google unban my domains after some time or I have to buy new domains everytime to run my add.
can you post some idea of the domain names that are banned and why they might not like them , if Google bans something it will almost certainly stay that way for ever.
