The six most common ASO mistakes are: targeting keywords that are too competitive, wasting the subtitle on a tagline instead of searchable terms, stuffing keywords into the description (Apple doesn't index it for search), never updating keywords after launch, copying competitor keywords instead of finding gaps, and neglecting screenshot optimization. Each mistake is fixable, and fixing even one can measurably increase organic downloads.
Most indie developers make the same ASO mistakes over and over. They put real effort into building a great app, then fumble the App Store listing with avoidable errors that tank discoverability. This post breaks down the most common ones we see, and more importantly, how to fix each before they cost you more downloads.
If your organic installs have flatlined and you're not sure why, at least one of these is probably the reason.
Targeting keywords that are way too competitive
This is the number one mistake. You pick a keyword like "fitness tracker" or "todo list" because it describes your app perfectly. Makes sense, right? The problem is every other app in your category had the same idea. The top results for those terms are apps with millions of installs and years of ranking authority. Your new app doesn't stand a chance.
Apple's search algorithm weighs download velocity, ratings volume, and metadata relevance. According to Apple's developer documentation, the app name, subtitle, and keyword field are the primary inputs for search discoverability. Even if your app is a perfect match for "fitness tracker," you won't outrank an app with 500,000 ratings when you have 12.
How to fix it. Target keywords where you can realistically reach the top 10 results within a few weeks. That usually means keywords with a popularity score in the 20-50 range and a difficulty score below 40. These terms get less traffic individually, but you'll actually show up in results, which means actual downloads.
If you need a structured process for finding these keywords, our step-by-step keyword research guide walks through the whole workflow from brainstorm to final keyword field.
Ignoring the subtitle (those 30 characters matter)
So many developers waste their subtitle on a cute tagline. "Your journey starts here." "Made with love." "Simple and beautiful." These sound nice, but nobody is searching for them. You get 30 characters in your subtitle, and Apple indexes every word for search ranking. That's valuable real estate.
The subtitle carries the second-strongest ranking signal after your app name. Using it for a slogan instead of keywords is like throwing away a free ad placement.
How to fix it. Put your second-most-important keyword phrase in the subtitle. If your app name is "Streaky - Habit Tracker," your subtitle could be "Daily Routine & Goal Builder." That's multiple searchable terms packed into 30 characters. Every word should be something a real person might type into the App Store search bar.
We've written a full breakdown on getting your app store subtitle right if you want to go deeper on this one.
Stuffing keywords into the description (Apple doesn't index it)
This one trips up developers who come from web SEO. On the web, Google indexes your page content, so keyword-rich copy helps you rank. The App Store works differently. Apple does not index your app description for search ranking. Your description matters for convincing people to download once they've found you, but it won't help you show up in search results.
We see apps with descriptions that read like keyword soup: "Best habit tracker app for daily habits, habit building, routine habits, good habits, healthy habits." It reads terribly, it doesn't help your rankings, and it actively hurts conversion because users can tell it's stuffed.
How to fix it. Write your description for humans. Focus on what your app does, why it's useful, and what makes it different. Save your keyword strategy for the three places Apple actually indexes: app name, subtitle, and the keyword field. Apple's App Store product page documentation confirms these metadata fields as the key inputs for discoverability.
Setting keywords once and never updating them
You picked your keywords at launch, submitted your app, and moved on. That was six months ago. You haven't changed them since.
The App Store isn't static. New apps launch daily. Competitors update their metadata. Seasonal trends shift what people search for. The keywords that made sense in September might be dead weight in March. And the only way to know is to check.
How to fix it. Treat keyword optimization as an ongoing cycle, not a one-time setup task. Here's a simple cadence:
- Every 2 weeks: Check which keywords are driving impressions in App Store Connect. If a keyword has zero impressions after two weeks, cut it and try something new.
- Every app update: Swap out 2-3 underperforming terms. You're already submitting a build, so there's zero extra effort.
- Seasonally: Plan keyword changes around predictable spikes. "New year goals" in January, "back to school" in August, "gift ideas" in November.
Each cycle gives you real data. That data makes the next cycle better. After 3-4 rounds, your keyword set will be dramatically stronger than what you launched with.
From the trenches
We tracked an indie developer's habit tracker app that launched with a solid keyword set. Popularity scores looked good, difficulty was reasonable. But after three months, half the keywords had gone stale. Two competitors had launched with aggressive keyword strategies targeting the same terms, pushing our developer's app off page one for several keywords.
Because they weren't checking their rankings, they didn't notice for almost two months. By the time they updated, they'd lost an estimated 400-500 impressions per day. After swapping in fresh keywords and retargeting gaps the new competitors had missed, impressions recovered within three weeks. The lesson: keywords decay. If you're not watching, you won't notice until the damage is done.
Copying competitor keywords instead of finding gaps
It's tempting to look at the top app in your category, grab their keywords, and call it a day. The logic seems sound: they're successful, so their keywords must be good. But here's the problem. Their keywords work for them because they have the download volume, ratings, and authority to rank for competitive terms. You don't.
Copying a competitor's keyword strategy is like a local coffee shop copying Starbucks' marketing budget. The tactics only work at that scale.
How to fix it. Use competitor research as a discovery tool, not a copy-paste template. The real value is finding gaps: keywords that are relevant to your niche but that your competitors aren't targeting or aren't ranking well for.
Look at 5-10 apps in your space. Note the keywords that appear in multiple competitors' metadata (those are validated, high-value terms). Then look for the terms they're missing. Long-tail variants, adjacent features, problem-focused phrases that describe why someone needs your app, not just what it is.
Tools like App Sprint's keyword research feature make this faster by showing you which keywords competitors rank for and, more importantly, where they're weak. That's where your opportunity sits.
Forgetting that screenshots sell the download
Keywords get people to your listing. Screenshots get them to tap "Download." A lot of developers treat screenshots as an afterthought: a few unedited phone captures thrown together at the last minute. That's a problem because your screenshots are the single biggest factor in conversion rate on the App Store.
Apple shows your first three screenshots in search results before anyone taps into your full listing. Those three images are your pitch. If they're blurry, generic, or confusing, people scroll past.
How to fix it. Design your screenshots like a landing page. Here's what works:
- Lead with the outcome, not the interface. Your first screenshot should show the benefit of using your app, not just a screen with data on it. "Track your habits and build streaks" over a clean UI beats a raw screenshot of your settings page.
- Add captions to every screenshot. Short, benefit-driven text that tells the viewer what they're looking at and why it matters. Keep it under 6-8 words per caption.
- Show your best features first. The first three screenshots appear in search results. Put your strongest, most differentiating features there.
- Make text readable at small sizes. People browse on their phones. If they have to squint to read your captions, those captions don't exist.
You don't need a professional designer. Tools like Figma (free tier), Screenshots Pro, or even Keynote can produce clean, effective screenshot frames. The bar is lower than you think. You just need to clear it.
Not tracking what's actually working
This is the mistake that ties all the others together. You make changes to your keywords, update your screenshots, rewrite your subtitle, but you never measure whether any of it made a difference. Without tracking, you're guessing. You might cut a keyword that was actually gaining traction, or keep one that's been dead for months.
App Store Connect gives you basic impression and download data, but it doesn't tell you which specific keywords are driving those numbers. And it definitely doesn't track your rank positions over time.
How to fix it. At minimum, track these three things for each keyword you're targeting:
- Rank position. Where does your app appear in results for this keyword? Are you on page one, page two, or nowhere?
- Popularity changes. A keyword's search volume shifts over time. A term with popularity 40 last month might be 25 now.
- Competitor movement. If a bigger app starts targeting your keyword, your rank will drop. You want to catch this early.
Track at least your top 15-20 keywords. Check the data weekly. Look for trends over 4-8 weeks, not day-to-day noise. When you see a keyword trending down, you can react before it bottoms out. When you see one trending up, you can double down.

What to do next
ASO mistakes are fixable. That's the good news. Most of these issues come down to a few recurring patterns: targeting keywords that are too competitive, wasting high-value metadata fields, not iterating, and not measuring results.
Here's a quick checklist:
- Audit your current keywords. Are you actually ranking for any of them? If not, they're too competitive.
- Check your subtitle. Is it searchable terms or a tagline? Fix it.
- Stop keyword-stuffing your description. Write it for humans.
- Set a calendar reminder to review keywords every two weeks.
- Study competitors for gaps, not to copy their strategy.
- Treat screenshots like a landing page. Lead with benefits.
- Track your rank positions so you know what's working.
If you want real data behind your keyword decisions instead of guessing, try App Sprint's keyword research tool. It shows popularity, difficulty, and competitor data in one place, built specifically for indie developers who don't have the budget for enterprise ASO platforms.
