    What is ASO?

    As of February 2019, there are approximately 2.2 million iOS apps that are available out there. That humongous number can be very intimidating, but fortunately, not all hope is lost for your app to get noticed. All thanks to App Store Optimization or ASO!

    ASO is simply a set of techniques or strategies that one employs to improve an app’s discoverability or searchability. If you own a flower shop out of possibly thousands of flower shops in your state, then how do you make sure that your flower shop comes out on top or on the first page of search rankings when potential customers look for flower shops on search engines like Google? Search engine optimization or SEO can help you with that. Similarly, doing ASO can significantly help your app get the attention it deserves. Competition is truly stiff, but that doesn’t mean that you can’t thrive!

    The latest Worldwide Mobile App Revenue and Downloads report released by SensorTower has shown that consumers from all over the world spent an estimated $25.5 billion globally on Apple’s App Store during the first half of 2019. Meanwhile, the revenue generated from first-time app installments reached $14.8 billion dollars. In light of these staggering figures, ASO will help you get your share of this robust market by providing greater visibility to your app, which in turn can lead to higher user traffic, and hopefully, higher user downloads.

    Chapter 2

    Why Is ASO Important?

    1. Cost-efficient organic growth

    Thanks to app store optimization techniques, your app’s visibility and popularity can grow among users at no extra cost to you when you execute them properly. No need to pay thousands and thousands of dollars just to promote your app every single time! With the right usage of keywords and creative inputs, your app’s download rate can exponentially grow in due time while keeping the acquisition costs at the minimum. Awesome!

    2. Effective targeting of desired market

    ASO is critically dependent on your solid understanding of your target market. With your target market in mind, you can then come up with the most relevant and unique keywords that will put your app ahead of the pack on search rankings. Doing proper keyword research and adding them to your app title and descriptions can eventually give your app greater exposure to its intended market, be they parents, moms, dads, students, teens, young professionals, or even kids! This is crucial because apps are made for people, and if your app is not receiving visibility among the people that it intends to serve, then there’s no point!

    3. Increased profitability

    Though generating revenue will obviously take time, using ASO can definitely help you in achieving profitability sooner rather than later. The more your app becomes publicized, the higher the chances that it will get downloaded, which is an absolutely good thing especially if you’ve also integrated some in-app purchases in there.

    4. Sustainable success

    Using ASO techniques, when properly executed, can bring you success for the long-term. It might be tempting for you to just spend a bulk of your savings paying marketing agencies and social media platforms to promote your app upon its launch, but the success you’ll get from doing that is just short-term. Spending so much money on marketing in the long run just to prevent the hype from getting down isn’t just sustainable. So it’s best to learn and master ASO so you can achieve stability!

    Chapter 3

    Your ASO Checklist

    Doing app store optimization isn’t exactly complicated. Here we’ve compiled the most important tasks that you need to do so that your app will enjoy higher search rankings and greater visibility:

    1. Get to know your keywords

    You’ve searched on Google before, right? And you don’t type full-length sentences on Google search, do you? Instead, you usually enter a few words or phrases here and there to search for the information that you need. Well, that’s no different from how users search for apps on app stores.

    Take time to put yourself in the shoes of your target users and think of the possible keywords that they will put in the search field to discover apps like yours. What’s your niche? There are online tools that you can use to look for these relevant keywords such as the Google Ads Keyword Planner or the KeywordTool.io. Try to look for those keywords that are not so common yet low in competitive rating. That way, you are positioning your app to penetrate those users who are specifically looking for apps that will best serve them. Also, don’t forget to be strategic in using your keywords considering that the iOS App Store has a 100-character limit in its bank of keywords.

    2. Focus on your app title

    The title of your app is highly crucial to your app’s overall branding, so always make sure that it is superbly optimized! Go for those titles that are attention-worthy, unique, and will truly intrigue users enough for them to click on it. The iOS App Store is really big on the usage of keywords, so  definitely add relevant keywords and tags to your app titles if there’s an extra space to do so. Given that users look for apps that will serve a specific function, consider adding your app’s main functionality into its title to draw more attention. If you’ve built an app that provides academic tutorial services to students, for example, then you can put “Your Personal Tutor 24/7” on the title to highlight your app services’ constant reliability and accessibility.

    3. Write your app’s description wisely

    With a 4,000 character limit, you need to maximize the space that’s given to you to discuss what your app is about and what it can provide. Use relevant yet unique keywords to outline your app’s functionality and how it stands out from the rest of the competition. Write concise sentences to discuss the “pain” that your app will be addressing. Focus on high-volume keywords as it relates to your app and its main strengths. Lastly, include a “call-to-action” phrase that will encourage potential users to actually download your app.

    4. Don’t neglect the aesthetics

    Part of an app’s branding is the promotional marketing that’s involved. A lot of users are visual people who prefer to see stuff than to read, so consider adding intro or explainer videos about your app and providing screenshots of your app’s main features. Research for brand colors that you can use that are connected to your app’s overall theme yet are easy on the eyes because that’s part of your app’s overall visual appeal. Small details like the type of font that you’ll use will also play a big role in attracting attention because let’s be real, some types of fonts should never be used in business. Overall, these creative inputs will play an important part in the users’ decision-making process that will hopefully lean towards your app.

    Tips to a Successful ASO

    Doing app store optimization is more than just ticking off items from a checklist. Accomplishing the necessary tasks to optimize your app must be coupled with sustainable strategies to ensure that your optimization efforts won’t die in the first few weeks or months. Competition is very fierce and app platforms continuously evolve, so here are some reliable app store optimization tips that will help you stay on top of your ASO game:

    1. Find marketing partners

    You should know by now that doing your own marketing efforts to boost your app’s publicity isn’t enough. Gain a good grasp of CPI campaigns and ad services on big social media platforms like Facebook and Twitter. Why? Because the people are there, and you need to get a slice of that humongous market. This also explains why keyword optimization is crucial because you need to know what the majority of people are using to search for apps that they want to download and use. Lastly, look for reliable bloggers and content producers who can promote your app. Start by achieving a solid understanding of your app’s niche and its target market. If you’ve developed an app to increase the productivity of students, then connect with content producers in the education sector. Make a list of these content producers and some stats or data about their reach so you’ll know the best people to connect with. Using marketing partnerships will certainly help you connect to an even bigger audience that you won’t possibly achieve if you will just do the marketing efforts on your own.

    2. Understand how Apple store works

    This is already common sense, but we’re still putting this tip out here just in case. Your app store optimization strategies won’t work to your advantage if you don’t have even have a solid understanding of the very same platform that will store your app. Thinking of having an in-app purchase? Then make sure that you name these purchases using the right keywords for greater visibility among users. Reviews are essential to help your app have greater publicity so try to get at least five customer feedback. And every time you do an update on your app in the Apple store, never forget to check the relevance of your keywords. As you know, making the title of your app very keyword rich is essential to gain market share, and you don’t want to accidentally leave irrelevant, non-performing keywords in your app’s title.

    3. Leverage the power of keyword search tools

    One of your goals is to get a list of keywords that are ranked very high yet are not as competitive. Uniqueness is also important because that will help you target a specific niche of your market. One online tool that you can use to harvest these unique keywords for your app is OneLook (www.onelook.com). One great feature of this keyword search platform is its Reverse Lookup function that will provide you with equally viable alternative keywords that can further propel your app in the search rankings. Make a list of these alternative keywords and use tools like App Annie’s Keyword Search to determine their competitive ratings.

    4. Don’t fall for common mistakes

    Or if you already did, learn from them and never repeat. Examples of these typical mistakes are including useless or even highly competitive keywords in your app title, keyword repetition that are far from being unique, failing to maximize Apple’s character limits by still using space after commas, and including the words “category” or even “app” in the name of your app.

    5. Patience is the key

    Expecting immediate results just by doing all of the tasks in the app store optimization checklist is too much. Remember that ASO is a lot of trial and error, a lot of experimenting until you hit the keywords and app design right, so having that determined resolve to keep on trying will go a long way. Just enjoy the process because that will build your knowledge and experience, which you can eventually share with others! Soon enough, you’ll reap the fruits of your hard work!
