The idea behind the keyword is that it allows Google to provide its users with the most relevant results possible. By identifying what your target audience is looking for, you can figure out what keywords will be the most effective for matching your content to their search queries. It is worth noting that users do have a variety of ways in which they can submit queries to Google’s search engine using keywords:
Text Query
A text query is the most basic type of query - a search performed using plain text. When a user performs a search query, they will often type out keywords instead of entire sentences. For example, instead of writing out “I’m looking for a Chinese restaurant in Brooklyn,” they might just write “Chinese restaurant Brooklyn.” Even if the entire query were to be typed out, the main keywords Google would identify would be “Chinese restaurant Brooklyn.”
Voice Query
With the emergence of voice technology, especially in regards to virtual assistants such as Amazon’s Alexa and Google Assistant, many users are performing voice queries. Because people don’t naturally speak in keywords, voice queries tend to be longer than text queries and more conversational.
Maps Query
A maps query is a query that prompts Google to display a map on its SERP. Keywords that prompt a map tend to indicate that the user is searching for a business or location. For example, if a user types in “Raleigh, NC” a map will appear along with general information about that city. If a user searches “Chinese restaurant,” then Google will display a map as part of its map pack, which would include three listings that match the query and their location on the map and will be nearby the user.
