The best ad for a gate is the neighbour's
A gate is seen from the street. People notice it at others' houses, think about it for months, and often decide in spring. Local advertising reproduces that neighbour effect, on a larger scale.
Show the jobs in the neighbourhood
A before-and-after video, an old wire fence replaced by an automatic gate, shown to homeowners in the towns around the job. It is the neighbour effect, without waiting for them to walk past.
Meta's fine geographic targeting suits it well: you can focus on the residential areas where you work.
The right moment
Fine weather revives outdoor projects. Starting advertising a few weeks before the peak gives campaigns time to learn, and the diary time to fill before competitors.
Those already searching
Broken automation, damaged gate, fence to replace after a storm: these searches go through Google. A campaign on precise keywords in your area captures them. I run both so they don't compete for the same customers.
