The SERP used to be ten blue links and not much else. Now it is a busy storefront of snippets, packs, ads, and AI answers, all competing for the same eyes before anyone reaches your listing.
The short version
A SERP, or search engine results page, is the page a search engine returns in response to a query. It includes organic listings and often paid ads, featured snippets, local packs, image and video blocks, and AI generated answers.
Why the modern SERP matters
Your rank is only one element among many on the page
Features like snippets and AI answers can capture attention first
Staying visible now means optimising for the whole page, including AI answers, which is where generative engine optimization comes in.
FAQ
Why does my number one ranking get fewer clicks than expected?
Because other SERP features, such as AI Overviews, ads, and packs, can sit above or around your listing and absorb attention before users reach it.
