1. Crawling: Googlebot systematically browses the web to discover new and updated pages.​
2. Indexing: Collected pages are analyzed and stored in Google's index, a vast database of web content.​
3. Ranking: When a user submits a query, Google evaluates numerous factors to rank pages, including:​
   • Relevance: How closely the page content matches the query.​
   • Quality: Assessed through signals like backlinks from reputable sites.​
   • Usability: Page loading speed, mobile-friendliness, and secure connections (HTTPS).
   • Context: User's location, search history, and settings.​

Google continually updates its algorithms to improve search quality, incorporating advancements in artificial intelligence and machine learning to better understand user intent and content semantics.​

📱 Social Media (SNS) Search Algorithms

Social media platforms employ algorithms to personalize content delivery, ensuring users see posts most relevant to their interests and behaviors.​

Functionality:

• Content Ranking: Algorithms prioritize posts based on factors like engagement (likes, shares, comments), recency, and user interactions.
• Personalization: User behavior, such as past interactions and preferences, informs the algorithm to tailor content feeds.
• Discovery: Platforms suggest new content or accounts by analyzing similarities in user activity patterns.​

For instance, Instagram's algorithm considers user engagement and direct shares to determine content visibility, while also enhancing its search capabilities to improve content discoverability.
