Google Autocomplete is a feature within Google Search that makes it faster to complete searches. Google's automated systems generate predictions that help people save time by allowing them to quickly complete a search.

Autocomplete predictions reflect real searches that have been done on Google. To determine what predictions to show, Google's systems look for common queries that match what someone starts to enter into the search box, considering factors like language, location, and trending interest.

Keyword Tool helps you employ Google Suggest for keyword research. It extracts Google keyword suggestions and presents it to you in an easy-to-understand interface.

To generate long-tail keyword suggestions, Keyword Tool prepends and appends the search term which you specify with different letters and numbers, places it into Google search box and pulls out keyword suggestions. Best part, all of it happens in a split of a second!

Why Is Keyword Tool One Of The Best Free Keyword Research Tools?

There are few places on the web where you can find keywords that people type in Google search box. One of the most popular sources of this information is Google Keyword Planner.

Unfortunately, data presented by Google Keyword Planner is meant to be used for paid advertising inside Google Ads platform. The keywords that you will find with this tool might be too generic and not very descriptive. In other words, barely useful for content marketing, blogging, or SEO.

Keyword Tool uses a different primary source to generate keyword ideas - Google Autocomplete. While some data is enriched with information from Google Keyword Planner, the keyword suggestions themselves come directly from what people are actually typing into Google search.

Google Autocomplete, the source of data employed by Keyword Tool, was created by Google to make search experience for people easier and faster.

Basically, Google shows the autocomplete suggestions whenever you start typing anything into Google search box. It is in Google's best interest to show the most relevant keywords in the autocomplete suggestions. Keywords that would help Google to retrieve the most relevant websites and help users find the most relevant content for their search query.
