My adwords account is about 5 years old and I have spent over $100k with it over the years, however I have not used it at all for over 1 year. I am now wanting to test some campaigns and I am wondering if it is beneficial to reuse the previous campaigns that have been paused since I last used them over 1 year ago? They had a long history of running and I had heard that it takes time to build up a "trustable" campaign in google's eyes.... I appreciate everyone's thoughts!
I also recommend to keep using your old account and campaigns. And it's true that google values the age of the account a alot. But be sure to check your campaigns at least once every day and to optimize if needed. AdWords has changed over the last year and it could influence your campai
