Search Engine Results Pages, or SERPs, are the pages shown by search engines when you make a search. The main part of a SERP is the list of results provided by the search engine in response to your query. These pages can also include images to help illustrate the information.
For example, if you search for "heating Ferndale WA" as shown in the example below, the SERP will display a list of relevant results along with businesses related to heating services in Ferndale, Washington.
It's worth noting that in addition to the organic search results, SERPs may also contain paid advertisements. These ads are clearly marked to distinguish them from the organic results.
