Proprietary assets were the third of five features associated with sustained Google visibility in a new Zyppy analysis of roughly 400 websites. The finding matters because it points to a more durable SEO approach than simply publishing more broadly similar content: create and maintain assets that are genuinely owned, differentiated, and difficult for competing sites to reproduce.
In Cyrus Shepard's Zyppy Signal analysis of websites winning Google in 2026, published April 9, 2026, 92.9% of winning sites had proprietary assets, compared with 57.1% of losing sites. The analysis examined winners and losers across the previous 12 months, including the March 2026 core update, using Ahrefs-derived traffic data and Spearman correlations between site characteristics and traffic change.
That is a meaningful association, not proof that proprietary assets alone cause a site to retain traffic. Still, the gap between the two groups makes ownership of differentiated material a practical area for website owners to assess, especially when search results increasingly surface concise answers and commoditized content is easy to replicate.
What Zyppy's research found
Shepard identified five website characteristics that strongly predicted sustained Google visibility:
- Offering a product or service
- Allowing users to complete a task
- Having proprietary assets
- Maintaining a tight topical focus
- Building a strong brand
The study places proprietary assets third in that set. Its methodology is important: it does not claim that every site with an owned asset will win a core update, nor does it reduce visibility to one ranking factor. It identifies a pattern among sites whose traffic performance held up better over the measured period.
| Study characteristic | Winning sites | Losing sites | What the comparison shows |
|---|---|---|---|
| Proprietary assets | 92.9% | 57.1% | Proprietary assets were substantially more common among the study's winning sites. |
The other four characteristics add useful context. A site that offers something, helps a visitor complete a task, stays focused on a subject, and develops a recognizable brand has reasons for users to choose it beyond a generic explanation. Proprietary assets can reinforce that distinction by giving the site information, utility, or material that is not interchangeable with an answer copied from elsewhere.
A practical way to build an owned-asset strategy
The research supports making proprietary assets part of content planning, not treating them as an occasional campaign. The first step is to identify which parts of a website are truly owned and differentiated, rather than merely rewritten versions of widely available information.
A useful working process is:
- Inventory existing assets. List information, tools, processes, data, product knowledge, or resources your organization controls and can maintain over time.
- Test for replaceability. Ask whether another publisher could create an equivalent page from public sources alone. If the answer is yes, the page may need more original input or practical utility.
- Connect assets to user tasks. The Zyppy findings also highlight task completion. Consider whether an owned resource helps visitors make a decision, evaluate an option, or complete a meaningful next step.
- Keep the subject area coherent. A proprietary resource is more useful to a search strategy when it supports a focused topic rather than sitting on an unrelated section of the site.
- Measure performance over time. Track organic traffic and visibility for pages built around owned assets before and after major search changes. This will not prove causation, but it can show whether the investment is producing a more resilient content base.
This is not an argument to publish assets simply because they sound exclusive. The value is in creating something useful enough that the site has a distinct reason to be returned in search results. The study's findings also suggest that an asset should work alongside a clear offering, a usable experience, topical focus, and brand strength.
For AI-assisted search, the strategic issue is similar. Systems that summarize common information make generic material easier to substitute. Content rooted in resources a company actually owns can provide a clearer basis for original pages, direct answers, and useful visitor experiences. That does not establish how any individual AI search product will rank a page, but it is a sound reason to reduce reliance on undifferentiated content.
For businesses trying to turn SEO effort into a more defensible acquisition channel, AI search visibility and SEO lead strategy can help identify where generic pages are losing distinction and where owned expertise can become useful search assets. GEO Search Leads focuses on practical opportunities to make content more discoverable in conventional and AI-assisted search, while connecting that visibility to qualified demand.

Frequently Asked Questions
What did the Zyppy study find about proprietary assets?
Zyppy's analysis found that 92.9% of winning websites had proprietary assets, compared with 57.1% of losing websites. Proprietary assets were the third of five features associated with sustained Google visibility.
Did the study prove that proprietary assets cause better Google rankings?
No. The analysis identifies correlations between website features and 12-month traffic changes. It does not establish that proprietary assets alone cause a site to perform better in Google.
What other features did Zyppy associate with sustained visibility?
The five features were offering a product or service, allowing task completion, proprietary assets, tight topical focus, and a strong brand.
How should website owners use this finding?
Website owners can audit which resources they truly own, assess whether those resources help users complete tasks, and measure the long-term performance of pages built around differentiated assets.
Conclusion
Zyppy's research provides a clear signal that proprietary assets were much more prevalent among websites that sustained Google visibility through the period studied. The finding is not a guarantee against future core updates, but it supports a practical SEO priority: build useful, differentiated resources that strengthen a focused site, support real user tasks, and are difficult to replace with generic content.
