The Compounding Asset
Advertising is a faucet. Open it and leads flow, close it and they stop, and the next campaign starts from zero. Content is the opposite kind of asset. A page that earns a ranking keeps collecting buyers month after month without another dollar behind it, and every strong page makes the whole site more authoritative, which lifts the next page faster. That is why the businesses that dominate their category in search are rarely the ones that sprinted for a quarter. They are the ones that published deliberately for years, and their competitors are now paying per click for traffic those rankings deliver free.
