Paid competition - the proof
2 incumbents are live on Google Ads (2 of them "persistent" - advertising ≥1 year and still active, the profitability proxy), averaging 3.9 yr of ad tenure. 0 advertise on LinkedIn and 2 run retargeting pixels (multi-channel paid presence). Combined SEMrush ad budget is $423k/mo.
High, sustained, multi-channel spend = a proven, copyable acquisition channel. Spend is present but not deep - validate the channel before committing budget.
Copy their PPC

Verdict
Moderate opportunity. Some proven paid competition; weigh the wedge and demand below against the incumbents' strength.
