Which ad platform should I start with to get clients?

Votel recommends Meta (Facebook and Instagram) ads as the first choice for most businesses. You can switch them on, get quick results and scale fast, and Meta's algorithm is very good at finding customers. For local services such as HVAC, Google Ads (including Local Services Ads) is also very strong, so the best choice depends a little on your niche and budget.

Another approach that works well for agencies: find businesses that already run ads but do nothing with the leads, or answer them slowly, and sell them a simple automation, such as speed to lead (texting every new lead within the same minute) or an AI that responds instead of waiting until the next business day.

If your own ads get lots of clicks and no leads, check that the ad matches the landing page, or try the Facebook lead form format, which keeps people inside the app.
