Why App Store Optimization Is Essential For Digital Marketing

With over seven million combined apps across the App Store and Google Play, app developers face a lot of competition. App store optimization increases the chances of users finding your app via an organic search by:

• Optimizing your listing for relevant keywords 
• Increasing the number of good reviews
• Adding high-quality images
• Translating your app into local languages

Ultimately, it makes your app listing look less like this:

And more like this:

App store optimization doesn’t just increase your visibility, though. It also drives more organic installs and increases conversion rates. That’s because high-quality images, detailed descriptions, and loads of five-star reviews make users more likely to click install. 

Why You Should Partner With An App Store Optimization Agency?

While you might be tempted to handle your app’s optimization internally, this could end up being an uphill struggle. Partnering with an app store optimization agency offers several benefits, including the following:

• Keep up with app store changes. App store optimization agencies are dedicated to understanding the algorithms that dictate app store rankings. They have teams of experts who keep tabs on changes in the industry, devise innovative strategies to stay ahead of the curve, and have the resources to implement these strategies effectively.
• Tap into a pool of experts. By working with an app store optimization company, you can leverage their expertise and experience. They’ll handle the nitty-gritty of ASO and banish the ASO myths, allowing you to focus on other critical aspects of your business, such as product development, customer service, and business expansion.
• Ongoing optimization. ASO isn’t a one-time task; it requires continuous effort, monitoring, and tweaking. The app market is an ever-evolving space, and keeping up with changes can be challenging without the right experience and expertise.

Whether you’re launching a new app or looking to boost downloads for an existing one, employing the services of an ASO agency can give you a significant advantage in a competitive marketplace.

Traits of A Good App Store Optimization Agency

Finding the right ASO agency for your brand can be tricky, especially when there are so many options to choose from. Narrow down your search by looking for the following traits:

• Industry knowledge: Pick an ASO agency with experience in your niche or vertical. Some app store categories are much more competitive than others, so it pays to work with an agency that knows what it takes to rank.

• Case studies: The proof is in the pudding. Always verify an agency’s expertise by looking at their case studies. Choose an agency with specific examples of how they’ve helped brands overcome similar challenges and generate the results you want to see.

• Awards: Peer recognition is the highest compliment an agency can receive. If an agency has won several well-known industry awards, they’ll probably be able to deliver results for you, too.  

Use these traits to draw up a shortlist, and then meet with a few agencies individually. There’s nothing better than a one-on-one consultation to see if you want to partner with these people for the long term.

The specialist also tracks app performance, analyzes competition, and tweaks strategies as necessary to ensure optimal results.

What is the future of app store optimization?

AI is the future of app store optimization. As with search engines, app stores will likely leverage AI to deliver personalized results and suggestions to consumers based on real-time user behavior and predictive analytics. Many of today’s existing ASO strategies will remain relevant, but driving engagement will become even more important. It won’t be enough to have users find your app, you must encourage them to download and engage regularly with it, too. 

How are apps optimized for the app store?

Apps are optimized for the app store through a combination of various strategies. This includes optimizing the app’s title, description, and keywords to align with search terms users are likely to use. Visuals such as the app icon, screenshots, and video previews are also optimized to attract user attention. Additionally, collecting positive user reviews and ratings, localizing the app for different regions, and regularly updating the app are all part of a successful ASO strategy.

How much does it cost to hire an app store optimization agency?

The cost of hiring an app store optimization agency can vary widely depending on the agency, the complexity of the project, the state of the app, and the specific goals of the app owner. Some agencies charge a flat rate, while others may charge hourly or offer different pricing models. It’s best to contact specific agencies for a customized quote.

How long does it take to see results from app store optimizations?

The timeline for seeing results from ASO can vary. However, it’s important to remember that ASO is a long-term strategy. While initial improvements may be seen in a few weeks, it can take several months to see significant results. This is because ASO involves continuous testing, tweaking, and optimization to find what works best.

Can I do app store optimization by myself?

Yes, you can do ASO yourself. However, it requires a deep understanding of app store algorithms, user behavior, keyword research, competition analysis, and other complex elements. Without this knowledge and the time to constantly monitor and adjust your strategies, you may not see the desired results. That’s why hiring an app store optimization agency is a good decision.
