Keywords and Keyword Phrases
Keyword / Keyword Phrase: A specific word or combination of words that a searcher might type into a search field. Includes generic, category keywords; industry-specific terms; product brands; common misspellings and expanded variations (called Keyword Stemming), or multiple words (called Long Tail for their lower CTRs but sometimes better conversion rates). All might be entered as a search query. For example, someone looking to buy coffee mugs might use the keyword phrase “ceramic coffee mugs.” Also, keywords – which trigger ad network and contextual network ad serves – are the auction components on which PPC advertisers bid for all Ad Groups/Orders and campaigns.
