One of the very early wins was ad creative diversification. I hired 5 different actors for them. Different ethnicities/genders was the goal I was aiming for. I wrote long scripts (like 60 seconds+) because that's what I've seen work in this industry. We also mixed them with some bulky in-your-face type of statics that did work quite well too.
I fixed their landing page setup. Instead of that 2-step thingy, I built a multi-step form that captures info at every single step. So even if people exit the form before completion, we still get their addresses just in case. No lagging step in the middle where people have to wait for the page to load.
I also changed the optimization event on Meta from addresses submitted to full forms submitted. Way higher intent leads.
The biggest thing was implementing offline conversions. I hooked up their Facebook Ads Manager dashboard with their CRM and we started seeing which ads were driving appointments, contracts, and deals closed. I even sent the conversion value (how much they think they'll make on the deal) so we could have in-platform ROAS. It was great.
Google Ads, on the other hand, surprisingly didn't do as well for them. It didn't do well before I joined them, it improved when I joined, but Meta was still outperforming Google by a two-multiple in terms of cost per contract.
I work with a ton of real estate investors/wholesalers, and this is one of the things I say all the time - not every ad account is the same. Their markets, their process, it's all different. Facebook Ads works really fucking good for them. But Google Ads doesn't work as good. We're still running Google Ads at 20% of the monthly budget because it's good to have diversity. Some weeks Google does good, some weeks it doesn't, but overall Meta is outperforming.
Another thing I implemented for these guys was a proper CRM setup. I'm talking text/email automations, offline conversion tracking, call tracking, speed to lead tracking, deal stage tracking, and EVERYTHING is hooked up and sent back to ad platforms. This helps us optimize for deals closed, not just leads.
