A storm creates a week of work in one night. Dozens of households search the same phrase the next morning, and the installer who already ranks for it takes the whole of that week.
Symptoms are the vocabulary. Pixelating picture, channels missing, no signal on one television but not another: nobody searches for the component, they describe what the screen is doing.
New points and wall mounts are the steady half. They have no season, they come from people redecorating or moving in, and they are far less competed for than repair terms.
Blocks and agents use another language entirely. Communal system, maintenance contract, response time: those searches come from somebody managing a building rather than watching a television.
