The Froomle Effect
Every visitor who arrives has a chance of clicking through to the next article. That chance repeats itself — and compounds.
Session length is the average number of pages a reader views in a single visit. A reader who lands on your homepage, clicks to an article, then clicks to a second article has a session length of 3.
It's the single best proxy for reader engagement — and it's driven almost entirely by one thing: how often readers choose to click from one article to the next. That's what the rest of this model is about.
Homepage CTR: of all homepage visitors, how many click into any article? This is your "front door" conversion rate. Article CTR: of readers who just finished an article, how many immediately click to read another one? This is your retention rate — and it's the number that compounds.
The chain looks short — but because the improvement applies at every single step, even a 2% CTR gain compounds into a meaningfully longer session.
If recommendation positions drive 15% of article-page clicks, even a perfect model is capped: it can only influence those 15%. A great engine in a tiny widget has a tiny effect. Surface area is the multiplier.

Every concept in this model connects to the next. Your traffic sets the stage. CTR determines how deep readers go. And because that CTR applies at every step of every session, even a modest improvement compounds into a meaningfully larger number of article views per month.
Froomle's impact flows through exactly this chain — from a CTR uplift in recommendation widgets, through your surface area, past cannibalisation, all the way to the pageview and session length numbers at the top of this page. The model you've just built is not a simulation: it's a prediction, calibrated to your own traffic.
At 100% article CTR every reader would keep reading forever. Small improvements therefore have a surprisingly large effect on session length.

The simulator shows the traffic impact — but there's a full revenue story behind it. More article pageviews means more ad impressions, and depending on your CPM, that compounds into significant additional revenue. We can walk through that calculation together with your actual numbers.
