I have been trying to learn Google Ads for about 9 months now. I am in the US working for a small construction company. At this point, I have 4 different campaigns (2 pro max, 2 search) for different facets of the business. But I only recently learned that you can have multiple ads within a campaign. Should I only have 1 campaign? Every time I feel like I learn something else about Google Ads, it makes me feel like I don't know anything at all. We are not spending a huge budget. Mostly I want to drive calls from local people who need our services. Help!
