Why does Google’s “About X results” jump when you flip pages?

Question

Weirdo · Accepted Answer

It’s an estimate, not a full inventory—and paging collapses duplicates, so the number drops. Google trades exact counting for speed; after you dig deeper it merges near-duplicate hits, and “about 1,200,000” often becomes “about 200.”

The “About X results” line is a fast estimate from the index, not a precise sum of every matching document. Google’s long-standing explanation: a ballpark figure lets them return quality results faster than an exact census would.

As you open later pages, the engine notices duplicate or near-duplicate documents and collapses them. That shrinks both the estimated total and how many result pages remain—so the early number wasn’t a lie so much as a coarse first pass.

In practice Google also caps how deep you can browse. Treating “About X results” as a precise corpus size for research or SEO usually misleads; use it as a rough signal of query breadth, not a spreadsheet cell.
