Partial year use of Ad Grants
I'm affiliated with a small Habitat for Humanity affiliate in Jackson, WY. We would like to use AdWords to solicit volunteers for our building projects and donors around a Community Foundation-sponsored fundraising campaign that lasts approximately 3-4 months.
During certain times of the year, if we aren't building or running a donation campaign, can we pause the AdWords campaign and resume it later and still qualify for Ad Grants?
Also, your rules say that all ads must point to the same URL; can they point to different minified URLs so that volunteers interested in building go directly to the page about our current jobsite, volunteer days and hours, etc.?
Re: Partial year use of Ad Grants
One of the requirements of the Google ad grant is that it does require active management. Due to this, you would have to have at least a "bare-bones" campaign running and being managed all year long. You may have other campaigns within the account that do only run during certain times of year for more shorter periods.
Regarding the URL rule, you may use any URL on the website/domain name that was approved for use with your Google ad grant, this includes subdomains. You may not, however, use URL shorteners, such as BIT.LY or G00.GL as these are not domains that were approved with use of your grant. Rest assured though, any URL within your approved website is good to use as a landing page within your ads.
