One lesser-known but crucial concept that might influence ranking is the Information Gain Score. There are many misconceptions about Information Gain scores. Here, I will try to explain about it in a simple way.
There is information gain in ML (Machine Learning) but information gain score in SEO doesn’t have any relationship with that.
Information gain scores don’t have any impact when a user searches for information for the first time. It comes into effect only when he does more searches on that same topic.
Information gain score is a method to give more information to that user with varied and relevant data than presenting the same information again and again.
Google has a patent for this process called Contextual estimation of link information gain filed in 2018 (Patent ID US20200349181A1).
Here’s a detailed, in-depth article on Information Gain Score in Google SEO, with the added sections to enhance quality, relevance, and depth.
What is Information Gain Score?
The information gain score is a measure that evaluates the amount of new information that a document or webpage provides on a specific topic compared to existing content. In machine learning, this metric is used in decision trees to identify which attributes provide the most information about a dataset. Google appears to leverage a similar concept in its algorithms to reward content that contributes uniquely to a subject.
In simple terms, information gain score in SEO can be understood as Google’s way of identifying content that offers fresh insights or value beyond what’s already available on the web. This means that pages that add depth, answer previously unanswered questions, or provide exclusive data might rank higher.
Information Gain Score in Google SEO: How It Impacts Content Ranking
In the world of SEO, Google is constantly fine-tuning its algorithms to deliver better search results to users. One lesser-known but crucial concept that might influence ranking is the Information Gain Score. Originally a term from machine learning, the information gain score measures how much useful information a specific piece of content adds to a given topic. Let’s dive into how this metric applies to SEO and how you can optimize your content for it.
How information gain score works
- A user searches on Google about a particular topic
- Google, then picks the documents relevant to that topic & apply their quality, usability and context related algorithms to sort the documents and show it.
- The User clicks on one particular document and reads it.
- When this user looks for the same information on Google, Information gain score comes into action.
- Google observes the documents, viewed by the user as the first set. Then consider all other relevant documents that the viewer has not viewed, yet as a second set of documents.
- They compare the content with first data (data already viewed by the user) with all documents in the second set. Their system tries to show more information to the user than presenting the same information.
- Based on this information they assign a score to every document in the second set. High score means more information than the first set and low score means almost the same information in the first data.
- Google displays the second set of documents in descending order as per the Information score by considering other ranking factors.
- Please focus on the above point, that Information gain score is only a factor among many others. It cannot alone change the ranking position.

- Focusing on Uniqueness: Creating content that addresses lesser-covered areas in a topic or providing a unique perspective that distinguishes it from other pages.
- Adding Value with New Data: Including recent statistics, research, or case studies that aren’t widely available.
- Responding Directly to User Intent: Crafting answers that specifically address what users are searching for rather than rehashing popular information.
