Ask a founder how their marketing is going, and you'll usually hear about likes, reach, and follower counts. Ask them how long a visitor stays on their website — and you'll usually get silence.

That silence is expensive. Because somewhere between chasing the feed and neglecting the website, most businesses have the equation backwards: the metric they obsess over rewards being loud for a second, while the metric they ignore rewards being worth someone's time — and it's the second one that search engines, credibility, and eventually sales are built on.

This post makes a case that sounds strange at first and obvious by the end: professional photography is one of the most underrated SEO investments a business can make. Not because Google counts megapixels — it doesn't — but because of a chain of very real, now well-documented mechanisms that runs from the quality of what's on your pages, through how long people stay on them, to where you rank. We'll walk the whole chain, with the evidence.
