There are two types of search results when someone searches on Google, organic search results and search ads. Search results show as links on Search Engine Results Pages (serps), they are not a part of Google’s Advertising Programs. Relevant search results, such as local business locations, contact information and driving directions also appear in Google Map Listings. These search results are independent of Google Advertising, unless a Map Listing is enhanced by “AdWords Expess.”
AdWords advertisements appear under “ads” alongside, above or below organic search listings. AdWords advertising is Google's #1 source of income.
