Google AdWords representative, Mini, started a Google AdWords Help thread asking people to submit some of their best practices for labor day AdWords campaigns.
Mini from Google said:
So far, no one has replied and Labor Day is this coming Monday.
So if you have any tips, do go to the thread and share.
And maybe this year, Google will post a labor day logo but historically, they have not – although they have in other countries.
