Disclosure Gap
Also known as: Google-disclosed data gap, query disclosure gap
A Disclosure Gap is what happens when Google tells you the total number of search visits, but does not show all of the searches that created those visits.
In reporting terms, it is the measurable difference between aggregate Search Console totals and the query detail Google chooses to disclose. A site can show total clicks, impressions, CTR, and average position for a date range while the query table shows only part of that activity.
For B2B technology SEO, that matters because the hidden portion can contain buyer-intent visits to product, reseller, pricing, support, and hardware planning pages. The missing query text cannot be recovered from Search Console alone, but the gap can be exposed by comparing total page, device, or day data against Google-disclosed query rows.
A proper performance report labels those query rows as disclosed query detail, not as the complete click record.
