Methodology

How it works

No magic. We combine 4 data sources + a topical clustering model.

500,000+ Discover articles

Our corpus continuously indexes articles that surface on Discover (FR + EN + IT + DE + PL + NL). We have title, date, publisher, traffic estimate, category. Not a guess — real signal.

Cross-referenced with Trends

We compare the editorial acceleration (articles published on the topic) against the demand signal (Trends volume), filtering out media-only echo chambers and keeping topics where readers actually engage.

Momentum score 0-100

Weighted blend: Discover-surface velocity (50%) + search growth (30%) + P90 traffic on the topic (20%). Above 80 = publish now.

Competition index

Low = fewer than 5 established publishers have covered the angle. Medium = 5-15 publishers. High = ≥15 publishers, you're late. Sweet-spot: low + momentum ≥ 80.

Top-performing title examples

For every topic, we surface the 2-3 best-performing titles in Discover for that thematic cluster. You see exactly which angles work — the promise, the emotion verb, the structure.

Best publish window

For each topic, we surface the optimal day-of-week + hour observed for the Discover peak across similar articles. Publishing 12 hours early ≠ publishing 3 days early.

FAQ

Frequently asked

Why 500,000+ articles, not more?+

That's our active corpus — articles indexed in the last 90 days, fresh enough to reflect current Discover behavior. We purge older items that no longer represent the current algorithm. Recency matters more than scale here: 500K fresh articles > 5M articles a year old.

Where do the traffic estimates come from?+

We use an internal prediction model blending public signals (social engagement, persistence in Discover over N days, publisher authority) calibrated against Search Console data shared by our consulting clients. Median and P90 are estimates, not official GSC numbers — but the relative ranking is reliable.

Why "beta"?+

The engine works but we're still calibrating momentum scoring per industry. Same caps as the other free tools: 3 scans / 24h as guest, 10 scans / 24h with a free account. For continuous or batch use, request a Pro access.

Which categories are supported?+

All of them — it's free-form topical clustering, not a closed taxonomy. Type pediatric health or European sharing economy or indie games, the engine groups matching articles and runs its analysis. More specific input → better output.

Is there a paid tier?+

To go beyond the 10 free scans / 24h, a monthly Pro plan unlocks continuous tracking of 5-10 topics + email/Slack alerts when momentum crosses your threshold + API access. Request a quote via /pro-contact.
