New Keyword Movement Detector: Discover your biggest keyword ranking progressions

If you’re familiar with ASO, you know how difficult it can be to fully measure the impact of your ASO work. When you release a new version of your app on the App or Play Store, you want to closely monitor how the changes you’ve submitted have impacted your keyword rankings.

We’re happy to present you our new keyword movement detector: You select an app and two dates and AppTweak shows you the keywords that have had the highest ranking movements from one date to another.


Making your keyword monitoring process simpler

Keyword monitoring is an essential step in ASO, but not the easiest. When you make changes to your app metadata, it can directly impact your app’s rankings on keywords. On Apple, the impact can be immediate and your app can suddenly start ranking or be unranked on a keyword from one day to another. On Google, the impact is more progressive, and less easy to detect.

Whatever the store, it is interesting to look at the impact the changes you made had on your app’s visibility after one day, one week or one month. Depending on the Store, the results can be very different. On Apple, you can see a huge boost in rankings during the first week after the release. This push then dies out if your app doesn’t convert enough on searched terms. On Google, the impact can be totally null from one day to another, but quite visible after several weeks!

Our expert tips on keyword monitoring

We generally recommend to wait one month to get the full picture of your ASO impact, but keep a close eye on rankings just after the release to be ready to make changes if things don’t go as expected. Monitoring the impact of your changes can sound time consuming, but this new feature will most definitely save you time!

With the Keyword Movement Detector, you can indicate two dates you’d like to compare your keyword rankings for - typically the release (Date 1) and a week or a month later (Date 2) - and AppTweak will provide the list of keywords for which the given app has had the highest ranking movements (both positive and negative) from one date to another.

In a couple of clicks, you can immediately identify the keywords you shouldn’t have removed or those who are performing very well. To make things even better, you can get these insights for any app on the Store. If you know a competitor has just made a release, you can check on which keywords its app has had the best ranking progressions and get an idea of the changes made to their keyword field.

Fetching the top keyword progressions

This all sounds great, but you’re probably asking yourself how does this magic work?

When you select two dates, AppTweak fetches all the keywords the given app ranked on at Date 1 and all the keywords the given app ranks on at Date 2. The algorithm then compares the app’s rankings on these keywords (position on date 1 vs. position on date 2) and highlights any movement that is considered unusual (keyword rankings movements that are bigger than usual).

It’s important to note that the keywords considered do not depend on the keywords you are following on AppTweak, but are fetched among all the keywords AppTweak is following in general. This helps detect keywords you might not have thought of or are missing out on.

The indicators we use in our algorithm

To define if a keyword ranking movement is usual or not, AppTweak uses a new indicator: the anomaly score. To compute this score, the algorithm first fetches the app’s rankings on a given keyword during 14 days before Date 1 and analyses the rank movements. This gives an idea of the volatility of the app’s rankings on the given keywords.

Each movement is given a weight taking both rank difference and rank level into account. The higher the rank difference, the higher the weight (i.e. a jump from 25 to 15 has more weight than a jump from 20 to 15). The higher the rank level, the higher the weight (i.e. a jump from 10 to 5 has more weight than a jump from 20 to 15).

The algorithm then compares these weights with the weights of the movements detected between Date 1 and Date 2. If the latter is above the average calculated over those last 14 days, the movement is flagged as unusual and given an anomaly score. The higher the anomaly score, the higher the magnitude of the movement and rank level.

In the results, AppTweak also shows the ranking movement, which is the number of ranks the app gained or lost on a keyword between Date 1 and Date 2. If the app starts to rank on a keyword, the tag “in” is used. If the app has stopped ranking on a word, the tab “out” is used. Finally, the column “Ranking” shows the app’s rank on Date 1 vs. its rank on Date 2.
