I've inherited an Adwords account with a few years' worth of history. The account has changed hands a lot though and there's a lot of clutter and confusing account architecture (confusing and redundant campaigns, thousands of inactive long-long-tail keywords for every match type, etc.).
I have a new architecture/strategy in mind but I'm unsure if I should start a new account from scratch, pause 90% of things and start some new campaigns, or delete a bunch of stuff permanently and start some new campaigns.
My fear with the pausing option is that I'll have to wade through a bunch of clutter in my daily management and reporting - I like to keep things clean. My fear with deleting is losing data - I'd like to be able to always look back at how things were. And my fear with the new account from scratch method is losing whatever account/campaign quality score or historical value the account has built over time and the logistics of having to stop the old account to create a new account. Can you even have 2 accounts with the same domain or would I have to delete the old account before launching the new?
For all my past PPC accounts, I started them more or less from scratch so this is new to me. Any advice/insights would be most appreciated.
Thanks!
Jeff
