Mobile App Reviews for ASO

Mobile App Reviews for ASO

Apple and Google both use app store reviews and app store ratings in their app store search ranking algorithms.

App store optimization as a practice and strategy is evolving as are the app store ranking algorithms that help to shape ASO.

Because the app store rankings algorithms are not shared publically, and differ between Apple and Google,  it is not possible to provide a specific weight of the quality, volume, or momentum of app ratings and reviews on search rankings.

While it does not appear there is a minimum number of ratings for top rankings in either Apple’s App Store or Google Play, it is generally accepted and understood that:

  • more ratings (and reviews) are better than fewer, and
  • higher ratings are better than lower

It follows then that any complete app store optimization strategy requires looking beyond the app listing and to not only building an app users love, but one that they are willing to rate and post reviews for.

Even with a somewhat cumbersome process, the best way to acquire lots of positive ratings and reviews is to build a great app that connects and resonates with its intended audience.

An amazing app is not enough.

Let’s review the actual process of rating and reviewing apps from the user’s perspective.

The process is a bit broken

Users can rate and review apps from their mobile devices in the app store app, or via the web if they are logged in.

The part that is a bit broken is that asking for a rating and review requires a user to stop using your app, leave your app, open a new app (the app store app) and navigate to the review section or tab.

While this is not ideal – there is another fairly common issue of irrelevant ratings.

Every marketplace from Amazon to Yelp suffers from their own issues with user reviews – so how do we make the most of the opportunity to hear from our users and influence new app installs and search rankings?

Let’s see if we can’t help our users a bit, by making it easier to leave our apps a relevant review.

Request app ratings

There are a few approaches to encouraging users rate your app that range from passive to downright annoying and disruptive to the user experience.

Add a link to your app listing in the app store in the menu

The least obtrusive to the user experience, adding a link in your app’s menu or settings directly to your app’s listing in the app store accomplishes two things:

  1. reminds the user to rate or review
  2. saves them the step of navigating to the app store and then your app

Not very proactive, but helpful. A more proactive approach would be actually asking for ratings and reviews.

Set an automated request after X days and X uses

A few years ago, a popular approach for requesting mobile app reviews was to simply schedule a popup that asked for a rating and review.

appirater-mobile-app-reviews

The publisher could set the popup to open on the 3rd app open (for example), or after 10 days or both.

This approach is flawed for several reasons:

  • a user just opened your app – even if for the 10th time, why divert them away from using your app?
  • while app opens are a good indicator of engagement, there are better times to request a rating and review

Ask for a rating and review during a high point

A better time to request a rating or review is when a user is at a high point in your app.

Maybe they passed a level, unlocked some content or otherwise just had a good experience in your app.

The ideal process

The ideal way for many apps to best support their users and create a funnel for acquiring ratings and reviews is checking in periodically on the user’s experience.

If there is an issue > funnel to support.

If the user is happy with the app > ask for a review.

This has been the approach adopted by many of the mobile app review and user management services.

The above example is actually from Apptentive – so let’s start there.

Apptentive

Offering ratings prompts and management, in-app polling and messaging and a growing list of features, Apptentive has built their business on helping publishers maintain a happy and engaged user base.

The Right Way to Ask Users to Review Your App

Restrictions

If you are thinking that there must be a more user-friendly way to prompt for ratings and reviews – allow me to throw some  water on the fire.

Incentivized reviews are not allowed by either Apple or Google

“We appreciate you taking the time to rating and review our app – here are some smurfberries”.

Not allowed and your app will be rejected.

The thinking is that these offers incentivize 5 star ratings (even though the smurfberries are rewarded regardless of rating).

Buying reviews can lead to review removals, or much worse

The small task website fiverr used to be littered with offers for app reviews.

Similar to buying Facebook “likes” or Twitter followers, you could just pay a service to generate a huge # of ratings and reviews for your app.

Both Google and Apple are not only very aware of this issue but often take significant steps to deter this behavior.

The purchased reviews will be discovered and removed, and your app will likely be penalized or even removed from the app store.

If you decide acquiring mobile app reviews and ratings is an important part of your app marketing, avoiding the above restrictions and using examples in this post will help you get started.

App Store Optimization Tools

Building and optimizing your app listing to tap into the massive organic traffic searching the app stores daily takes the right app store optimization tools.

Below we will cover some of the very best ASO tools, from getting ratings and reviews, to designing descriptions and screenshots that convert with your target audience and more.

While this list is not in any particular order, a good place to start is with working with your target audience.

Focus Groups

Screenshots, the app name, the icon, even the description all have a huge impact on how your target market perceives your app.

Google Play provides tools for A/B testing all of the above app listing elements in their “experiments” module, but working with focus groups provides a few significant advantages.

1 – test and receive feedback on a wider range of variations

Small changes to the color of an icon can have a big impact on conversions (from app listing views to installs), but focus groups allow you to test big differences – with one design direction failing to resonate while another shows great promise.

Mobile app publishers and designers can get an idea of what resonates with their audience by looking at competing apps, but outside of that guidance, there is no way to really know what will drive your target audience to install your app without asking them.

2 – feedback is quantitative and qualitative

As with most A/B testing platforms and in Google Play experiments, you will be able to see which design, description, screenshot order, icon etc.. converted best and whether the results were statistically significant, but you won’t know why.

Focus groups provide an opportunity to experiment boldly and then garner qualitative feedback from the test subjects.

Why did they pick icon design #2 over 1, 3 and 4?  Why was the app name confusing or misleading? Which screenshots best explained the most important features of the app to them and why?

While focus groups are unique in the quality of potential feedback, running ads to a poll, or polling your existing lists (email or social media) are two other ways to test listing elements prior to publishing.

Ratings and Review SDK

Ratings and reviews have an impact on app store rankings in both Apple’s App Store and Google Play.

Even bad ratings seem to be better than no ratings – which appears to be some broken measure of engagement.

While there does not appear to be some magical minimum number of ratings required for top rankings, more ratings is generally accepted as better for app store positioning.

Rating apps is not easy for users. It takes multiple taps and leaving the app to rate or review an app – a tall order even if you (the user) love the app.

Because the best indicator of user satisfaction tends to be retention, engagement or lifetime value (or some mix of the 3), if it were not for the impact on rankings, many app publishers would not prioritize app store review prompts.

But alas, while ratings matter, publishers are encouraged to find ways to request ratings with the least impact on the user experience.

Publishers can set up ratings and review prompts with a custom implementation or use a proven model for customer support and ratings acquisition by partnering with services like that offered by Apptentive.

While ratings and reviews are important for app store rankings and app optimization, prompting for reviews should always account for the impact on the user experience to ensure you are not chasing ratings at the expense of revenue.

Review Mining

Similar to the above, review mining is actually a tool for competitive research.

What features or functions are your competitors’ app users complaining about, requesting or commenting on that your app does better?

Review mining helps guide app listing strategies from which keywords and phrases to target to which features to highlight in screenshots.

Consider a top ranked photo app that allows for adding text to user photos.  The reviews complain that posting to Tumblr does not work well or at all.  Your photo app works great with Tumblr.

You may have thought this was your 12th most exciting feature, but it could well be your app’s top differentiating feature and worth prioritizing in the app listing.

App Store Data / Intelligence

As the saying goes, “where there is mystery – there is margin” and there is a ton of mystery in the app stores.

App store data and intelligence services span topics from monetization models and estimated lifetime values of competitive apps, to which SDKs apps are using to estimates on what specific apps are paying for new users by geo.

It is hard to say how accurate many of these tools are, but many services are popping up to carve out a niche and provide just a little more insight to help their clients improve their results in the app stores.

When it comes to tools specifically for app store optimization, features publishers should look for include:

  • mobile app store search terms – data on the keywords and phrases the market is using when searching the mobile app stores.
  • evaluation of how the app name and keywords or description fields work together for broad coverage of relevant search terms (the “keyword matrix”).
  • suggested keyword and phrase targets by category, trending, current traction and competition.

In previous posts, we have explained why app store data and web data are very different. It may not be obvious but several app store optimization tools use the free Google keyword planner built using web search as a proxy for app store search volume and related phrases.

Positioning mobile apps in the app stores globally for discovery and installs from the massive organic app store search traffic volumes is one of the best long-term strategies for success in the app stores.

Creating an app store listing, testing and regularly adjusting to changing market demands is called app store optimization or ASO. In the below whitepaper, we will introduce:

  • the opportunity in the app stores
  • the business case for investing in ASO
  • how Apple and Google index mobile apps in their app stores
  • data on how users are searching from their mobile devices
  • and finally discuss the various elements of an app listing and the impact each has on visibility, rankings and conversion in the app stores

Highest ROI Activity

As the costs of acquiring mobile app users from paid install campaigns increases, a complete ASO implementation becomes more valuable. On page 4, we present why ASO provides a long-term competitive advantage and will likely drive the best investments returns (ROI) of any app marketing effort.

How Apple and Google Index Apps

Apple and Google index mobile apps differently, and the entire field of app search, indexing, and rankings is dynamic and fluid.  But there are some established principles and best practices for giving Apple and Google exactly what they want so they can index your app correctly. How the app stores index apps and the best practices for each element and overall are explained in detail.

How Users Search for Apps

Discover how your target market searches the app stores, and how it differs from web search. We break down a few examples and analyze how the motivations and intent of users searching the app store is very different from user intent when “Googling” something.

5 Smart Strategies For App Store Screenshots

Without looking, do you know which element of an app listing makes up 75% of the view in the app store search results?

Here is what Apple’s app store search results look like on my iPhone 6:

IMG_0265 2

The first result is Twitter’s Periscope. While the listing includes the app name, publisher, icon and even ratings, the first two screenshots take center stage.

Optimizing an app listing for visibility in search results consumes a lot of what’s talked about in ASO, but converting viewers is how we actually acquire users.

And since the screenshots are such a big part of the view a potential user sees when navigating the app store – we need to make sure our screenshots are optimized for conversion.

Features First

If you have read some of our other posts on app store optimization for Apple and Google Play, you know we are big on highlighting features.

Features and brands are how users search the app stores. With your market research using an app store intelligence platform, you know which features of your mobile app are most important or differentiating.

When focusing on your app’s features, make sure the first two clearly show what your app is for and what it does.

Visiting the Periscope listing again – they have obviously decided to position the app in two ways:

  • explore the world (for those consuming videos on Periscope)
  • broadcast live from anywhere (for those making videos)

Even if you had never heard of Periscope and you saw the listing in results from a search for  “live video” or some other related search, the first two screenshots tell two different types of potential users exactly what the app is and does.

Screenshots 3, 4 and 5 go into additional features including discovery and the social features, but screenshots 1 and 2 show off Periscope’s most unique, important and differentiating features.

Focus Group Tested

Identifying your app’s most important features is one thing, designing screenshots that are understandable and encourage action is quite another.

From the graphics used to the call to action or copy, and of course even color and font choices impact how potential users react to your screenshot design.

Testing a variety of screenshot designs with a focus group made up of your target audience can provide actionable feedback that is hard to get anywhere else.

Two benefits of working with a focus group on app screenshots designs are:

1)  testing a wider variety of design directions and calls to action

A completely different design direction that flops won’t impact actual conversion rates and installs like live-testing would.

2)  qualitative and quantitative feedback. Most A/B testing on live traffic is data driven

“Screenshot Design A” converted at a 15% higher rate than “Screenshot Design B” so let’s go with “A”. With focus groups, we can get written feedback as to why a user liked one design over another, what was confusing, what they liked etc…

Increasing conversions in app store views from 25% to 30% (a 20% increase) can mean thousands of new users each month.

Order Testing

Maybe your app has 2 or 3 features that really set it apart, and you are not sure which to lead with?

As we have discovered, the first 2 screenshots are visible in search results – so experimenting with order can have a real impact on conversion rates.

Bamboo Apps shared they saw an increase of 50% in installs from rearranging screenshots.

A/B Testing

Multivariate testing (or A/B testing when there are only 2 variations) is virtually impossible on Apple’s app store, but Google Play recently announced support for testing of all sorts of app listing elements.

Called “Experiments”, Google Play helps publishers test different icons, names, descriptions, and screenshots by country – and on whichever percent of live traffic we choose.

Since these experiments are being run on live traffic, tests should be limited to smaller variations in screenshot designs, copy and order – and limited to one test at time for the best results.

Screenshot Localization

Depending on where your current traffic is coming from, screenshot localization can provide an easy improvement in conversions.

Because screenshots are limited in scope, changing out text and graphics is much more simple than localizing an entire app.

How screenshots are localized really depends on who the app is for and what it does, but the call to action copy is generally a pretty reasonable project for those new to app localization.

A recommendation – don’t rely on Google Translate as we discussed in a previous post on app localization.


Optimization is an ongoing process of improvement where changes and gains add up.

The optimization of an app’s screenshots for conversion represents “low hanging fruit” for many app marketers and publishers.

By implementing the above strategies for app store screenshots, your app will be positioned to achieve solid gains from small efforts.

App Store Optimization Tips

According to a recent report from comScore, the vast majority of app installs come via the app store, with search being the leading mobile app discovery method.

Optimizing an app listing for the app stores continues to be one of app marketing’s highest ROI activities.

What follows is 5 app store optimization tips.  For more detailed information on the specifics of optimizing an app listing, check out our guides for Apple ASO and Google Play.

Use app store search data instead of web data

The way people search the app stores is different than how they search the web. Intent is different, what we are searching is different (applications vs literally anything on the web), and app store search results have trained us how to search.

Using Google’s free web search suggestion tools provides a poor proxy for how potential users of your app are searching the app stores.

For more on the differences between app store search and web search, check out our post containing examples from our app store intelligence tools.

Build a matrix of keywords that build relevant phrases

Armed with app store data about how your target market is searching the app stores for apps like yours, the goal then is to cast a wide net at these keywords and phrases.

The best way to achieve wide coverage is by building app titles, descriptions and using the keyword field (Apple only) to create a keyword matrix.

This approach tends to “open up” keywords that would otherwise be too broad, vague or competitive to target.

For example, “Free” may not be a good keyword to target on its own.  “Free” and “Game” is still very vague.  “Free”, “game”, “runner”, “zombie”?  Where the keyword “free” didn’t make sense, combined with additional feature-based or descriptive keywords, “free” may be a valuable modifier.

The above 4 keywords would result in coverage for:

  • “zombie runner”
  • “zombie runner game”
  • “zombie game”
  • “free zombie game”
  • “free zombie runner”

For just those 4 words, there are 24 ways to arrange them into 4 word phrases, and more than 40 ways to arrange them in 1, 2, 3 and 4 word phrases.

This starts to get complicated as Apple limits the characters in the keyword field, and has a somewhat subjective policy to keyword stuffing app titles (see below). Google limits the app name and the short description to 30 and 80 characters respectively.

These constraints require marketers to make decisions on which individual keywords deliver the very best relevant phrase coverage.

If the average length of an English word is 8 characters, we are trying to select the 15-20 keywords that provide the widest coverage of relevant searches. 15 targeted words can create a keyword matrix of almost 3,000 1,2 and 3 word phrases.

As you can guess, advanced optimization software provides a solution to this challenge.

Optimize creative elements via a focus group and then in the store

Visibility in app store search results is only part of the path to acquiring organic users in the app store.

Once a potential user sees your app’s listing, the app title, icon and screenshots play a large role in converting a viewer into a user.

An increase in conversion from 25% to 30% can mean thousands of new users in your app.

Because the icon and screenshots make up the majority of an app’s store listing - investing in optimizing these creative elements has shown to have a large impact on app store conversions.

Google not only sees creative testing as a tool for developers, but as a way to for developers to provide a better user experience to users.  They recently announced support for live multi-variate testing in Google Play.

Since traffic is live, and because Apple does not yet support testing in their app stores, testing bigger variations of your icon, screenshots and even the order of screenshots with a focus group is a recommended approach.

Another key benefit to testing creatives with a focus group prior to making changes in the live app store listing is receiving qualitative feedback. More than just identifying a winner, this feedback can provide insights as to why a design performed better than another.

Avoid short-term hacks to build a long-term competitive advantage

As with many closed systems, from Google’s web search algorithm to email spam filters to the app stores, where there is mystery – there is someone profiting from selling hacks.

Some approaches to app store optimization are extremely short sighted, and many result in an app’s removal from the store or even developer account suspension.

Check out our best practices and top ASO hacks to avoid here.

Don’t keyword stuff app titles

Google has virtually eliminated the abuse of keyword stuffing in app titles by limiting the app name in Google Play app listings to 30 characters.

Apple, on the other hand, provides a whopping 255 characters for app titles! App publishers recognized there was no reason to sweat the selection of keywords used in the 100 character limit in the keywords field, as there were 255 characters to play with in the app title.

Apple has since responded by rejecting apps who abuse this app title space, removing (key)words from the title and rejecting an app’s metadata and requiring a new app submission without the keyword-stuffed title.

The market has caught on as well, where apps with keyword-stuffed titles perceived as low quality and spammy.


As mobile device usage continues to increase, with app usage growing even faster, implementing a process for ongoing app store optimization just gets more critical for companies invested in mobile as a channel, hub or resource for clients, partners and leads.

Armed with these app store optimization tips, and with the right partner, marketers and published have a solid foundation for long term mobile app success.
