If you qualify for the Google Ads credit, you will want to make the most of it. Qualified accounts will just show a credit up to $1000, and this number is based on historical spend.
When I work with my clients, one of the things that they all wish is that they had asked for customer reviews/testimonials WAY sooner. Because if they had asked every happy customer between now and then, they would have some hard proof of the amazing services or products they offer. Instead, now they have to go back to that customer and ask for it.
