Last Update: September 8, 2016

Don’t know what keywords to use or struggling to find new keyword idea for your app?

Doing keyword research for your app costs money. You can just hire an expert or agency or do it yourself but not all mobile developers, or publisher has that amount of money.

Doing keyword research without a budget is difficult especially if you don’t know where to start. Well, you’re dead wrong! Here are some few online tools and methods you can use to find keywords for your app.


Google Tools:

I want to start with the most available tools out there which are Google. They have some useful tools that can you can use for your keyword research. If you are publishing on Google Play Store, it’s also advisable to follow their guidelines for SEO from Google Webmasters.

#1 Google Autocomplete

Google AutoSuggest App Store Optimization

The reason it’s the first on the list is it’s almost available anytime. As we type in the Google search bar, Google predicts some possible search term that might be similar to what you are searching Google states that:

An algorithm automatically generates autocomplete predictions without any human involvement. The algorithm is calculated on objective factors, including how often others have searched for a word.

Autocomplete just proves that what Google suggest to your query is the most used keywords. Follow this link if you want to learn more about – Google Autocomplete.

#2 Google Trends

Google Trends AppMarketingBoost

While Google Autocomplete gives more like a random suggestion, Google Trends can show the statistics of a search query at a particular time. It’s made to show some data changes, behavior, and the popularity of keywords around the globe. You can also filter your results based on time and different countries.

Using Google Trends will help you to gather new and trending keywords for your app. It is also a very useful tool if you are planning to do some app localization as you can set the results to show only from a particular country.

#3 Google Keyword Planner

Update: Some Google Adwords users with lower monthly ad spend may now show data ranges instead of exact value.

This is the bread and butter for keyword research. If you are not aware of Google Keyword Planner, the keyword planner helps new or experienced advertisers to get through the process of creating new ad groups and ad campaigns. It can help you identify keyword’s popularity over time, filter out low-volume searches and competitive keywords and more.

It is one of the most powerful keyword research yet free tool based on top SEO and Social Media Marketing experts around the world.

#4 Google Correlate

Google Correlate for App Store Optimization

Although it is an entirely different tool from the other keyword research tools here, it lets you see keywords in a different angle. It helps you see correlation data over time by geographical location. Perfect for apps with target users from the US.

It’s a bit confusing, but you can easily learn how to use it. I let Google explain this tool to you go to their Google Correlate Tutorial Page if you want to find out more:

Google Correlate is like Google Trends in reverse. With Google Trends, you type in a query and get back a data series of activity (over time or in each US state). With Google Correlate, you enter a data series (the target) and get back a list of queries whose data series follows a similar patter.

Here are my favorite free keyword research tools:


RankBrain’s free tier is a good source of keywords in general.

Rankbrain is another free keyword research tool which can help us find new keywords for our app. Although the full feature of this tool needs a premium/paid account, the free “no-sign up” tier is good enough to find new keywords.

What makes me list this incredible tool to our list is its ability to find dedicated autocomplete keywords directly from Google Play Store. Aside from Google Play, you can also find keywords for YouTube, Google News, Google Images, and more.
