Building the Semantic Core for an App or Game

The concept of the semantic core for an app or mobile game. Building the semantic core: searching, analyzing, and organizing keywords.

What is the semantic core?

The semantic core is a collection of search queries and key phrases that best describe an app, covering its entire functionality and relevant associations. Users type these words and phrases into search engines to find the app they are interested in. Developers integrate these keywords into the app's metadata to enhance its visibility in search results.

Steps to Building a Pull of Keywords

When working with keywords, it's essential to focus on a few important parameters:

  • Relevance: Keywords should accurately reflect the app’s features or gameplay.
  • Traffic: This is the number of users searching for a particular query over a specific period (usually daily). The higher the frequency, the more popular the query.

Types of Keywords

Keywords can be categorized in different ways:

  • By Relevance:
    • Relevant
    • Irrelevant
  • By Length:
    • Short Tail: Search queries consisting of one or two words
    • Long Tail: Key phrases made up of several words
  • By Traffic Volume:
    • High-frequency
    • Medium-frequency
    • Low-frequency

Sources for Keywords

  • Common Sense and Logic: Consider what functions the app performs or the genre of the mobile game.
  • App Store Suggestions: Use the auto-suggestions provided by app stores.
  • Competitor Metadata Analysis: Analyze the metadata of competing apps.
  • Apple Search Ads: Use insights from Apple's advertising platform.
  • ASO Tools: Utilize analytical ASO tools for deeper insights.

Key Stages in Developing a Semantic Core

  1. Keyword Collection
    Start by forming an initial, broad list of potential search queries.
  2. Analysis and Refinement
    Analyze the collected keywords and refine the list to include only the most relevant and specific queries.
  3. Prioritization and Clustering
    Finally, prioritize keywords based on their relevance and traffic volume.
