Information Gain in SEO: What the Patent Can and Cannot Tell You

Information gain is a useful way to ask whether an article adds something a reader needs. In SEO discussions, however, that editorial idea is often mixed with claims about a secret Google score. A patent does not establish which techniques Google currently uses in Search, their weights, or a formula publishers can optimise.

What the Google patent describes

Google’s patent Contextual estimation of link information gain, published as US11354342B2 on 7 June 2022, describes estimating additional information in documents in relation to information already presented to a user. Its proposed implementations concern context: what someone has encountered affects what might be useful next.

This is a description of a patented approach. Reading it does not verify deployment in today’s search results. It does not justify presenting vector distance, unique words, bounce rates or follow-up searches as a confirmed publisher-facing ranking formula.

Use published guidance to set your content standard

Google’s people-first content guidance asks creators to assess originality, completeness, sourcing and value beyond rewriting other pages. Its ranking systems overview explains that many signals and systems contribute to results. These sources support investing in useful content; they do not establish a universal information-gain threshold or a guaranteed penalty for repeating a definition.

The practical workflow below is an editorial recommendation from TecVarsity. It is not a Google scoring model or a tested ranking experiment.

Start with a decision the reader needs to make

Write down the audience, their situation and the decision the page should support. For example, a small business comparing automation tools may need to understand approval steps, failure recovery and who maintains the workflow. Another generic list of features may leave those questions unanswered.

Review a few relevant resources and record the questions they already answer. Then identify an unresolved question you can answer accurately. Choose the gap because it matters to the reader, rather than because no competitor uses a particular phrase.

Add evidence you can actually support

A documented example, a clearly explained calculation, an annotated screenshot or a comparison with explicit criteria can make advice easier to apply. If you ran a test, state the setup, date, limitations and observations. If you did not, label the example as illustrative and avoid first-hand claims.

For an illustrative automation comparison, show how each proposed workflow handles an incomplete enquiry, a duplicate submission and a failed notification. Separate documented product capabilities from your proposed design. Do not report time savings, conversion improvements or reliability figures without supporting records.

Original surveys and customer examples require care: explain the sample and method, obtain suitable permission and protect private information. A small observation should not become an industry-wide conclusion. Expert quotes should be genuine, attributed and approved for the intended use.

Revise an existing article with a simple review log

Record the page URL, intended reader, important claim, supporting source and date checked. Mark each material claim as supported, uncertain or needing removal. Keep an explanation when you change a recommendation so the next editor understands why.

Next, add the missing explanation or evidence and remove irrelevant padding. Check that the introduction matches the body, headings help readers navigate, links work and examples have clear limitations. Preserve useful basic explanations: novelty alone is not a reason to remove information a beginner needs.

For large page collections, use a small reviewed pilot before scaling. Our programmatic SEO guide explains a draft-first approach. For crawl and indexing checks, see the technical SEO checklist.

Measure outcomes without inventing a score

Keep a dated change log and review relevant Search Console impressions, clicks and queries over a suitable period. Where consent and measurement allow, assess useful actions such as qualified enquiries or tool completions. Consider seasonality, technical changes and search updates before attributing a difference to the rewrite.

A third-party content score is that tool’s estimate, not proof of Google’s internal assessment. A ranking change does not isolate a single cause. The achievable editorial goal is a page that answers its intended question accurately, with evidence and limitations readers can inspect.
