About Google Autocomplete APIs

Keywords are the words and phrases that help you perform any search on search engines such as Google, Yahoo, Bing, and others. Search engines have sophisticated algorithms called bots that crawl through the internet to give you helpful and relevant results to your query. This keyword prioritization is otherwise called search engine optimization, abbreviated as SEO.

It is not always that we have the exact words or phrases to describe our search question. In human nature, it is not still possible to remember specific terms, and that is where search suggestions come to our aid. Relevant recommendations allow us to refine our search in a more focused and understandable way.

Google autocomplete APIs is a tool that allows individuals to make the searches much faster. They have documentation that produces the suggested words and phrases by Google suggest API whenever a search request is initiated.

How Google Autocomplete APIs work

Owners of the API give you a unique key called a token. The token acts more or less as a passcode that approves you to use the API. Through the developer’s API console, you select a preferred IDE (Integrated Development Environment) such as Python, JavaScript, Java, and the likes.

From your IDE, you can then build the API based on your business logic and website requirement. The first thing is to assign the seed keywords that are relevant to your website. Set the base as Google suggests URL and the required parameters to integrate with your website.

A client uses the search tool and type in a given keyword called the primary keyword. Google Suggest API receives the request to communicate with the server to process the request. After processing, the API transmits back the response with a list of related search suggestions. JSON and XML are the popular formats for writing API requests and responses.
