Why it matters
Organic clicks cost nothing per visit and keep arriving for years after the work that earned them: the closest thing marketing has to an appreciating asset. Buyers also weight it: people know which results are ads.
How it works
Engines rank organic results by hundreds of signals summarisable as: does this page best serve the query, and does the web vouch for this source? You influence it through content, technical health and reputation (SEO) rather than budget.
What to do about it
Track organic as its own channel with its own goals, and feed it consistently: the businesses that treat it as a compounding investment rather than a faucet are the ones it eventually carries.
