The patent focuses on using different types of historical data associated with documents (e.g., web pages) to better match them to user queries.
Main idea of the patent
Based on historical data analysis, the system generates a document score that enables more relevant and personalized search results.
Key elements of the patent
The patent analyzes four main areas of historical data:
Document history

Significance for SEO
The patent suggests a greater emphasis on long-term activities and analysis of a page's historical effectiveness in terms of both content and link profile.

Koray framework
Koray Tuğberk Gübür's Concept
Koray Tuğberk Gübür emphasizes the fundamental role of historical data in SEO and search engine algorithm operation. His approach extends the patent's conclusions with practical implications.
New definition of historical data
Koray defines historical data not as the mere passage of time since page creation, but as a measure of user engagement quality over time.
This includes all interactions indicating how users perceive the page:
Positive signals
- Long sessions on the page
- Multiple interactions
- High satisfaction
- User returns
Negative signals
- Quick exits
- Lack of engagement
- High bounce rate
- No scrolling
Fresh and consistently positive historical data carries more weight than old, outdated signals.
- Koray Tuğberk GübürTopical authority formula
Koray combines historical data with his topical authority concept:
Topical Authority = Topic Coverage × Historical Data
High topical authority is not possible without a solid history of user engagement
Clearing negative historical data
Important
Negative historical data requires generating new, strong quality signals to "overwrite" previous weak signals. Improving content quality is not enough - you need to systematically build positive interactions.
Best practices
-
Regular updates
Keep content up-to-date and encourage users to return -
Engagement optimization
Focus on page speed, responsiveness, and intuitive navigation -
Content quality
Focus on evergreen content that fully addresses user intent
Final conclusions
- Historical data is the foundation of Google's ranking decisions
- Consistent user satisfaction builds lasting authority
- Strategic content planning over time is key to SEO success
- Avoid artificially inflating metrics - it hurts in the long term
