1. Competitor Apps

Analyse your competitor’s keyword data

Take time to analyse your competitor's keyword data to bolster your own ASO strategy plan.

The first thing you should look at is their app title since that’s the most influential place where keywords are ranked from, which means that any keywords you see in it are likely useful for informing your keyword choices. Other than that, descriptor keywords in an app’s description can also give you great ideas for your keyword research.

Remember, in ASO, a ‘competitor’ is any app that’s targeting the same keywords as you. In other words, apps that are in the top 10 for any of your keywords are your ‘competitors’.

2. User Reviews

Read your and your competitors’ user reviews

Reading your and your competitors’ user reviews will give you more insights into how users describe apps in your niche. Peruse through these reviews to find popular phrases and keywords that best describe your app in your users’ language.

Pro tip: On App Store Connect, you can sort reviews to prioritise the ones that have been voted the most helpful by other users. This helps you to zero in on reviews that resonate most with people.

3. Autofill Results and Related Keyword Searches

Research and compile a list of autofill results and related keyword searches

One of the simplest ways to find new keywords and keyword variations is by typing one of the keywords you’ve already identified into the search bar, which will pull up a list of autofill results and related keyword searches.

Autofill results and related keyword searches are popular searches that other users have done that are relevant to your search, which in turn means they may be relevant for your app. You may come across many irrelevant suggestions, so filter through them and weed out the unrelated ones.

4. Apple Search Ads

If your app is on the App Store, you need to use Apple Search Ads to find the optimal keyword set – after all, it is the first-party platform that provides real, reliable App Store-sourced search data.

On Apple Search Ads, you can gauge your keywords’ popularity using the popularity scores, which are indicated by the number of blue dots – the more dots there are, the higher the popularity of your keywords.
