Frequently asked questions
How is the volatility index calculated, and what is it?
The volatility index measures how much today's Google Discover feed differs from its usual pattern over the previous ~30 days. It is built from three factors against that baseline: new publishers entering the feed (the largest weight), shifts in how impressions are spread across domains, and shifts between material formats. The result is normalized against each market's own typical variation, so the 0-10 scale is relative: about 3 is an ordinary day, 5-6 is elevated, and 7 or higher is anomalous - a likely unannounced Discover update.
Why does Google Discover Updates data differ between countries?
Discover updates often roll out unevenly - first in some regions, later in others, and barely at all elsewhere. Because the index is measured against each country's own baseline, the same calendar day can look calm in one market and anomalous in another. That is why it helps to watch both the global view and individual markets.
What is the format interest index?
It estimates how strongly Google Discover is pushing a given material format (news brief, explainer, listicle, recipe, ritual/horoscope, and so on) on a given day. It weights a format's share of impressions and its share of article count equally, so a few viral pieces cannot skew it and low-volume formats are not over-counted. Across all formats the values sum to about 100 per day, so each one is that format's share of Discover's attention.
What do a rising and a falling Discover updates index mean?
For the volatility index, a higher value means the feed is reshuffling more than usual - publishers and formats changing fast, which often accompanies an update; a low value means a stable, ordinary feed. For per-format and per-category interest, rising means Discover is giving that format or topic more reach (a cue to lean into it), and falling means it is fading. The trend and shift-vs-mean fields show the direction and size of the move versus the recent average.
How often is the data updated?
The underlying Discover feed is collected continuously, and the indexes are recomputed roughly once an hour. The value for the current day or 3-hour window keeps refining as new observations arrive. The oldest days in a 30-day window can be blank because there is not enough history before them to judge how unusual they are; recent days are always computed.
How to read this. The volatility index (0-10) measures how much the Google Discover feed reshuffles versus its recent baseline - driven by new publishers entering the feed, shifts between publishers, and changes in material format. About 3 is a typical period; 7 or higher is anomalous and usually signals an unannounced Discover update. All metrics cover a rolling 30-day window. Read the full methodology.
