Google Autocomplete is the feature in Google Search that shows predicted queries in a dropdown while someone types. Google says the predictions are based on real searches that happened on Google. For SEO, they are a free source of the phrasings people actually use.
How does Google Autocomplete work?
Google’s help page names four factors for the predictions shown in the dropdown. These are the language of the query, the location it comes from, trending interest in a query, and, for signed-in users, past searches. Two people typing the same letters can therefore see different predictions.
Google calls them predictions and says they are meant to help people finish a search they already intended to do. They are not search results, and they are not a statement about what a page should rank for. Automated systems and enforcement teams remove predictions that violate Google’s policies, for example hateful, violent or sexually explicit ones. The help page also lists feature-specific rules for elections, health and disparaging predictions. People can report predictions they consider inappropriate.
How do SEOs use it?
A common method is to type a seed term, add a letter or a question word, and write down the predictions. Tools automate this by sending many such requests. The result is a list of long-tail variants and typical questions that can become headings, FAQ entries or new pages. Because predictions depend on location and history, a logged-out browser window gives results that are easier to compare (practice, not a Google recommendation).
Predictions come without search volume. A phrase can appear in the dropdown and still be rare, so volume has to come from a keyword tool.
Example
Typing “canonical tag” and adding the letter “w” produces predictions that start with those words. Each prediction is one phrasing that many people finished that way. A writer can check the SERP for each one and decide whether it deserves its own section. The exact predictions change by location and time, so they have to be checked live.
Common mistakes
- Treating a prediction as proof of demand. Google does not publish volume for it.
- Collecting predictions while signed in, which mixes personal search history into the list.
FAQ
Are Google Autocomplete predictions the same for everyone? No. Language, location, trends and, for signed-in users, past searches all influence them.
Is Autocomplete the same as Google Suggest? Google Suggest is the older name. Google’s current documentation uses “autocomplete”.
