Commodity Fingerprint — The Lens

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

The value proposition is unique within its niche, distancing it from the commodity ‘educational excellence’ patterns of most schools. It avoids cliches like ‘holistic education’ or ‘nurturing potential’ in favor of utility-driven language like ‘Smart Search’ and ‘fully formatted citations.’ A minor penalty is applied for the generic ‘Frequently asked questions’ structure, though the content within is specific.

Commodity Fingerprint is read from the page structure first: templated copy tends to repeat the same heading patterns and shapes seen across an industry. Below is the heading hierarchy captured, then the known cliché patterns for this industry to weigh it against.
