Impressions is the number of times a result, ad, listing, or content item is shown to users.
It matters because organic search compounds over time when pages are technically accessible, useful, differentiated, and connected to real search intent. Clear SEO terminology also helps teams avoid shortcuts that create long-term risk.
Example
A search report can record an impression when a result meets the report’s visibility rules. The count does not mean the visitor opened the page; use clicks and on-site behavior to examine the next steps separately.
