ASO vs SEO: What Transfers and What Actively Hurts
App store optimization and search engine optimization share a shape and almost none of their mechanics. Coming from SEO gives you a real head start on some things and a real handicap on others, and the handicaps are the expensive part.
What genuinely transfers
- Intent-first keyword thinking. The instinct to prefer a specific phrase with clear intent over a broad head term is exactly right, and if anything matters more in the stores because the result sets are so much smaller.
- Measuring before and after. Change one thing, wait, read the trend. Identical discipline, identical reason.
- Competitor analysis as a source of terms. Reading what already ranks and working backwards works the same way.
- Title-tag instincts. The app name is the closest analogue to a title tag: heavily weighted, short, and doing double duty for humans and the index.
Three SEO habits that hurt in the stores
- Writing long, keyword-rich body copy for iOS. Apple does not index the description. Effort spent optimising it is spent on nothing, and copy written for an index reads worse to the human deciding whether to install. On Google Play the instinct is correct, this is the single most confusing difference between the two stores.
- Repeating keywords for density. In Apple's keyword field, a repeated word is a wasted character out of exactly 100. There is no density benefit and there is a real cost.
- Chasing links and off-site signals. There is no link graph. Traffic you send to your store page can convert into installs, and installs help, but you are buying a conversion, not building authority.
The differences side by side
| SEO (web) | ASO (app stores) | |
|---|---|---|
| Indexed text | Effectively the whole page | Name, subtitle, keyword field (iOS); name, both descriptions (Play) |
| Off-site signals | Links are central | No link graph |
| Behavioural signals | Indirect and debated | Direct: installs, conversion, retention, ratings |
| Content volume | More pages can mean more traffic | One listing per app per locale |
| Result set size | Millions of pages | A shelf, often tens of apps |
| Time to reindex | Hours to days | Days to two weeks |
| Demand data | Search Console, keyword tools | Apple Search Ads only; nothing equivalent on Play |
| Hidden keyword field | Deprecated in the 1990s | Alive and important on iOS |
The row that surprises people most is the hidden keyword field. Meta keywords died in web search decades ago; Apple's equivalent is one of the highest-leverage things you control.
Why the app stores are a closed system
In web search you can create pages, earn links and build authority over years. In an app store you have one listing per locale, a fixed set of fields, and a ranking that is dominated by what users do after they see you.
That makes ASO a narrower discipline with a shorter feedback loop and a much lower ceiling on effort. There is a point, usually reached within a few weeks, where your metadata is genuinely optimised and further gains have to come from the product: better conversion, better retention, better ratings.
An SEO used to a large surface area often keeps looking for more levers. There are not more levers. That is not a failure of research.
Where an SEO should start
- Treat the app name as your title tag and spend real time on it.
- Learn Apple's 100-character field properly. It is unlike anything in web SEO and it rewards precision.
- Write two different descriptions: one for Play's index, one for a human on iOS.
- Stop looking for off-page work. Put that time into screenshots and ratings, which are where the behavioural signals come from.
Frequently asked questions
Is ASO the same as SEO?
No. They share the goal of ranking in a search result and almost none of the mechanics. There is no link graph in the app stores, behavioural signals like installs and retention matter far more, and Apple does not index your description at all.
Do backlinks help app store ranking?
Not directly. Traffic from a link can convert into installs, and installs help, but the link itself is not a ranking signal.
Does keyword density matter in ASO?
No. In Apple's 100-character field a repeated word is a wasted character. On Google Play, two to four natural mentions across the description is sufficient.
Which is faster to see results, ASO or SEO?
ASO usually. Metadata changes typically take one to two weeks to be reflected, where competitive web SEO can take months. But ASO has a much lower ceiling, once metadata is optimised, further gains come from the product.
Can I use the same keywords for both?
The research transfers; the deployment does not. App store searches skew shorter and more transactional than web searches, and the field structure is completely different.
