ASO vs SEO: what's the difference?
ASO vs SEO comes down to where people search. App store optimization (ASO) gets an app ranked inside an app store's search and charts. Search engine optimization (SEO) gets web pages ranked in Google and Bing. Both rely on keywords, page copy and trust signals, but the ranking inputs are different: installs and ratings drive ASO, links and content drive SEO. In 2026, a third channel exists. AI app stores in ChatGPT, Claude, Muse, Meta AI and MCP registries list apps too, and ASO principles apply there as well.

ASO optimizes for installs and ratings, SEO optimizes for links and content
ASO ranks an app inside a store. SEO ranks a web page in a search engine. Someone searching a store wants to install something right now, so the store ranks apps people install and keep. A search engine ranks pages that answer a question, and links from other sites are a strong signal that a page is worth showing.
Ranking signals in the App Store vs Google search
In the App Store and Google Play, the words in your title and keyword fields determine which searches you can appear for. Installs, ratings and reviews then determine how high you rank. A new app with good keywords but no installs will sit low.
In Google, your title tag, headings and body text determine which searches a page can rank for. Links from other sites, and how well the page answers the search, determine the order. A page can rank with no sales at all if it answers the question best.
ASO and SEO keyword research use the same starting point
Both jobs start with a list of the words people type. In ASO, you place them in the app title, the subtitle and Apple's 100-character keyword field. Google Play reads the full description instead. In SEO, you place them in the title tag, the H1 and the first lines of the page. To find terms for AI stores, use app store keyword research built for ChatGPT and Claude.
What ASO ranking means and why position matters
ASO ranking is the position of your app in a store's search results or category chart for a given keyword. ASO teams track their rank for each keyword every day, because the top spots get most of the taps.
Typical ASO tool pricing across budget tiers
Most ASO tools cost between $0 and $200 per month for one app. Large suites and agencies cost more and often quote prices on a call. To see what each tool does at each price, compare the best ASO tools by budget.
ASO for AI app stores: ChatGPT, Claude and MCP
AI assistants now have their own app stores. ChatGPT has a plugin directory with search and categories. Claude has a connector directory with 734 connectors (October 2026). Muse, Meta AI and MCP registries list apps and servers too. Each one ranks apps by the name, the description and the example prompts, and ChatGPT and Claude also suggest apps inside a chat when they fit the task. This works like classic ASO, except there is no keyword field and people often find you from a chat instead of a search box. If you ship into ChatGPT or Claude, start with AI app store optimization.
Choosing between ASO, SEO and AI store optimization
- You have a mobile app. Start with ASO in the App Store and Google Play. People find apps there by searching the store.
- You sell web software. Start with SEO. Buyers search Google for the problem you solve and read your pages first.
- You have a ChatGPT plugin or a Claude connector. Do AI app store optimization next to SEO. Your listing and your tool descriptions decide whether the assistant finds you.
Frequently asked questions
Is SEO dead now with AI?
No. Google still sends a large share of web traffic, and AI assistants read web pages to write their answers. What changed is that some answers now appear without a click. See how GEO vs SEO vs AEO compare for AI answers.
How does ASO work?
You choose keywords, place them in your title and listing, and improve your icon, screenshots and reviews. The store then ranks your app for those keywords based on how many people install it and how they rate it.
Can SEO help app downloads?
Yes. Web pages that rank for app keywords, such as "best meeting notes app", send people to your store listing.
