5 Key ASO Metrics for Success in the App Stores

Between implementing a variety of ASO strategies, researching your app competitors, and of course actually coding and developing, there’s a lot to consider when getting an app ready for production.

Don’t let your momentum slow once you’ve actually launched your app. Tracking key metrics about your app is a crucial part of your strategy to ensure that your app doesn’t just start strong, but has continued success over the long-term.

Gaining insight based on solid data will allow you to react, refine, and adjust in a more informed and intelligent way, and that spells success for your app.

The 5 ASO Performance Metrics

This post covers all the key ASO metrics for your app that you should be tracking right out of the gate:

Search Score, Chance Score, The Number of Competing Apps, Visibility Score, and Keyword Ranking. (And if you don’t track them yet, start now!)

To gain access to these metrics, sign up for a free MobileAction account. Read on to learn what each means and how to use the data to reach your audience and get more downloads.

Search Score

Search Score App Metrics

Search Score, viewable next to each keyword you’re tracking on your Dashboard, is one of the most important  when it comes to your app’s ASO strategy, but it’s also an easy one to misinterpret.

You see, Search Score measures the number of relative searches for a given keyword, with a number from 0 to 100. The reason this can be a tricky metric is that higher Search Scores may seem to imply that those are the ones you should target first, or that you should target your keywords in order of Search Score.

But it’s not quite that simple.

The highest-ranking Search Score keywords are the most difficult to rank for because they also usually indicate the most competitive keywords. So you could spend your energy attacking a few keywords with high Search Scores and still end up ranking low enough that your audience may never see your app.

It’s a better strategy to target good long-tail keywords and some intelligently-chosen keywords with good (but maybe not the best) Search Scores. In fact, you should balance your Search Score tracking and decision-making with the other metrics in this post.

Once you’ve picked your targeted keywords based on these techniques, be sure to check your keyword rankings at least once a week, if not more frequently.

Chance Score

Chance Score Mobile App Metric

Chance Score is a percentage score based on MobileAction’s estimate of your chances of being in the top ten for a particular keyword in your app’s specific category.

This is a powerful metric.

The % Chance Score is determined based on keyword analysis, but also provides measurement specific to you based on your linked iTunes account, so don’t neglect this step.

Once you have both the Search Score and the Chance Score for a potential keyword you want to rank for (or, ideally, a collection of keywords that you’re tracking over time), you can use both scores to determine which keywords to attack.

For example, you may discover that a keyword has a high Search Score but a very low % Chance Score. That one is easy to discard, move down your priority list, or modify with some additional words to make it a long-tail keyword.

Or vice versa: you find a keyword that has a low Search Score but a high % Chance Score. Depending on the circumstances, and how many other keywords you have with a potential for ranking on, you may choose to go with this one.

Just as with Search Score, track your keywords’ Chance Scores week over week so you can have the data to back up your decisions to either continue to target the same keywords, or make adjustments.

Number of Competing Apps

Your dashboard also provides a Total Apps number–in other words, a metric that shows the number of competing apps for a given keyword.

Gauging the competition is a big part of ASO; in fact, a deeper competitive analysis element should be a part of your overall strategy. But the Total Apps figure can be a good barometer for your keyword targeting, especially when Search Score and/or % Chance Score don’t provide you with a decisive push for one keyword over another.

Keep your finger on the pulse of your app’s performance by tracking your Search Score, Chance Score, and number of competing apps regularly.

Visibility Score

Mobile Action invented the app Visibility Score in order to track one of the most important things about your app: how discoverable your app is in the app store(s).

No one will download your app if they can’t see or find it–that’s common sense, right? But quantifying visibility was difficult in the past, and thus figuring out how to actually make your app more visible in the app store was a tricky, overly subjective endeavor.

With the Visibility Score for iOS and the Google Visibility Score for Android apps, you’ll get a score between 0 and 100 based on MobileAction’s proprietary algorithm.

The Visibility Score incorporates keyword performance, category ranking performance, and review/rating performance–three areas that significantly influence your app’s discoverability and thus overall performance.

It’s important to have a well-rounded strategy to improve your Visibility Score, rather than targeting only one thing (say, category ranking) at the expense of the rest. The Visibility Score keeps you “honest” in this regard, since it measures multiple parts of your performance.

So what should you do in order to get a higher number?

Improving your ASO will, in turn, improve your Visibility Score.

And in fact, using each of the three previous metrics described here–Search Score, Chance Score, and number of competing apps–can have a big impact on Visibility Score.

Using those pieces of information to decide which keywords to target, and continually tracking and adjusting based on the data changing over time, will impact the three areas that impact your Visibility Score.

Keyword Ranking

Finding and optimizing keywords is good and all, however, you should also keep close track of your performance over each keyword as well.

This is particularly important for you to be able to understand which keywords perform well and which are lacking (even if the rest of the metrics were great). At the end of the day, if you are not ranking at least in the top 10 for a keyword, what’s the point of targeting it?

You can check your historical keyword rankings on the MobileAction dashboard to see how your rankings have changed over time and if your standing for the keyword is improving or getting worse.

Keyword Ranking history as a vital ASO Metric


As you can see, the key metrics for tracking your targeted keywords and app’s performance are all part of the same ecosystem. It’s one that includes all the best App Store Optimization strategies, too.

So be sure to include tracking and analysis as part of your regular routine. Remember to check your app reviews too!
