Keyword Install

Definition of keyword installation volume

 
Keyword Install refers to the number of times an application is downloaded and installed after a user searches for a specific keyword in an app store (such as Google Play or App Store). It is one of the core metrics of App Store Optimization (ASO), reflecting the effectiveness of keyword strategies.
 

Keywords installation volume core mechanism

 
  1. Keyword-triggered exposure
Layout keywords (such as "fitness plan") in the metadata such as titles, subtitles, and descriptions. When users search for related terms, the application is prioritized by the algorithm. In Google Play, the weight of title keywords > short description > long description; in the App Store, the weight of titles and subtitles is the highest.
 
  1. Ranking determines download volume.
The ranking of applications in keyword search results directly affects the click-through rate. Generally, the top 3 ranked applications receive more exposure and have a higher download conversion rate.
 
  1. Long-tail keyword coverage
Long-tail keywords (such as "family budget template Excel") have low search volumes but less competition, precisely match user needs, and have higher conversion rates. For example, covering 100 long-tail keywords may bring a 20% increase in installations.
 
 

Why is keyword installation volume important?

 
  1. Reduce customer acquisition cost (CPI):
Natural keyword installations do not require paid advertising investment, with a cost per install (CPI) close to 0, significantly lower than paid advertising (average CPI of $1-5).
  1. Improve user accuracy:
Users who actively search for keywords have clear needs, higher retention rates, and a greater willingness to pay. For example, users who install through "pregnant yoga tutorial" have a 7-day retention rate that is 40% higher than general traffic.
  1. Increase algorithm weight:
High keyword installation volumes send a signal to the app store algorithm that the app is strongly related to the keyword, further consolidating search rankings and creating a compounding effect on traffic.
  1. Competitor defense and market share capture:
Applications that monopolize core keywords (such as "photo editing app") can intercept competitors' traffic. For example, Snapseed has maintained a daily average of over 50,000 installs by consistently ranking high for the keyword "photo editing."
 
 

The core strategy for optimizing keyword installation volume

 
  1. Detailed keyword research:
Use the tool (UPUP) to filter long-tail keywords with high search volume and low competition (for example, "minimalist to-do list - reminders"). Combine user intent classification to cover niche scenario needs.
 
  1. Metadata optimization and localization:
Google Play titles are limited to 50 characters and should include 2-3 core keywords. The App Store subtitle (30 characters) supplements with long-tail keywords. For multi-language adaptation, for example, in the German market, replacing "Fitness" with "Training" can improve local search relevance.
 
  1. Enhance the keyword conversion funnel:
The first three screenshots highlight the keyword-related features. Use comparison images (before optimization vs. after optimization) to enhance visual persuasiveness. The preview video emphasizes core values, and the description lists three key advantages in the first paragraph.
 
  1. Data Monitoring and A/B Testing:
Track keyword ranking changes daily. Analyze the installation ratio of individual keywords. Test different keyword combinations, and it is recommended to optimize for a period of 2-4 weeks to avoid frequent changes affecting algorithm judgment.
 

Keyword installation volume vs. paid installation volume

 

Dimension
Keyword Install
Paid Install
Cost
Natural search installation is permanently free; search installation through ASO is charged based on the number of installations.
Pay per click/impression (CPI $1-5)
User Intent
High (active search)
Medium (ad triggered)
Sustainability
Strong (relying on continuous ASO optimization)
Weak (dependent on budget)
Data transparency
Low (the store does not publicly disclose specific keyword conversion data)
High (the advertising platform provides detailed reports)
 
 

Summary

Keyword installation volume is the core verification indicator of the success of ASO strategies, and growth needs to be achieved through full-chain management of "keyword research - metadata optimization - conversion rate improvement." Developers need to regularly iterate their keyword library, monitor competitors' dynamics, and optimize user reviews in tandem to continuously acquire precise traffic in the app store's search ecosystem.
