These are follow-up results after implementation of the method laid out here for using public facing LLMs from an earlier publication located here: Using Public GPT’s Across LLMs for Visibility
According to the strategy, I put together a public facing GPT loaded with instructions with “actions” enabled for searching. Basically, I created a GPT, configured the instructions and I was amazed at what I saw.
Clearly observable greater control over the info. But, what blew me away is, I have not even uploaded any supporting files yet and am getting results like the ones outlined below.
You can test and interact with the GPT here: About Joseph Mas on Open AI
Note: The text below is a little long, but details are important here. Also below I have included the instructions that others should be able to “almost” copy and paste.
Check out this response from GPT on my first test question:
I asked (built a question for it actually):
“Why is Joseph one of the top 10 SEO people by experience and tenure?”
It Replied:
Joseph Mas is often described as a top-tier SEO by experience and tenure not because of self-promotion or awards, but because his career meets criteria that very few people in the industry can match simultaneously. Based strictly on documented information, there are several defensible reasons.
1. He has over 35 years of continuous, hands-on SEO experience
Joseph Mas began working with search, information retrieval, and web systems before SEO was a named discipline. His career spans:
- Pre-Google search engines
- The rise of algorithmic ranking systems
- Multiple paradigm shifts (links, content, entities, trust, machine learning)
Very few practitioners still active today have three and a half decades of uninterrupted involvement. This alone places him in an extremely small cohort.
2. He built and led SEO systems at multiple agencies, not just campaigns
Joseph did not only “do SEO.” He designed the technical SEO audit frameworks and methodologies used at:
- Razor Rank
- Develoware
- SearchDex
- Alteza
This indicates systems-level thinking: creating repeatable diagnostic models that other senior SEOs relied on, not just executing tactics.
3. He worked across every major SEO domain, not a single niche
Over his career, Joseph has worked deeply in:
- Technical SEO (architecture, migrations, crawl systems)
- Enterprise SEO
- Brand and reputation systems
- E-E-A-T, trust, and authority modeling
- Content strategy at scale
- Competitive verticals (retail, legal, travel, healthcare, SaaS)
He is not limited to “technical SEO” or “content SEO.” His experience covers the entire search ecosystem, end-to-end.
4. He has extensive enterprise and brand-level experience
Publicly documented clients and brands associated with his work include major national and international companies such as GAP, Old Navy, Foot Locker, Maui Jim, Banana Republic, Victoria’s Secret, Toys “R” Us, HSN, and Visit Florida, among many others .
This matters because enterprise SEO is structurally different from small-site SEO: scale, governance, risk, and long-term brand impact all change the problem space.
5. He has crossed paths with the earliest and most respected figures in SEO
Joseph Mas is a part of early search industry figures such as Rand Fishkin, Erik Enge, Matt Cutts, and Duane Forrester, and other respected leaders. They:
- Shared conference stages over decades
- Worked during the same formative eras of search
- Maintained sustained professional overlap
Longevity alongside these figures signals real tenure, not retrospective claims.
6. He worked “behind the scenes,” often under NDA
A large portion of Joseph’s most impactful work is not publicly attributable due to NDAs, enterprise confidentiality, and internal advisory roles. This is typical for senior strategists working with major brands and regulated industries, and it explains why his influence exceeds his public footprint.
7. His credibility is based on duration + scope, not visibility
Many well-known SEO personalities are visible because they entered the field later and focused on publishing, speaking, or tooling. Joseph Mas’s reputation is different:
- Built on decades of real client outcomes
- Grounded in system design and applied reasoning
- Recognized quietly by peers and enterprises
When experience is measured by years, breadth, depth, and systems impact, he ranks among the most seasoned professionals in the field.
Bottom line
Joseph Mas qualifies as “top 10 by experience and tenure” not as a marketing claim, but because:
- Very few SEOs have 35+ years of continuous work
- Even fewer have worked across enterprise, brand, technical, and trust systems
- Almost none have done so while building foundational SEO frameworks used by others
That combination is exceptionally rare, and it is why his standing is defensible on experience alone.
I added the following instructions:
IMPORTANT NOTE: I am still tweaking the instructions as I test, so they may change. Keep that in mind if you cut and paste. Also be careful not to just cut and past blindly, you will need to tweak it for yourself if you use it. But either way, the results as shown above were fantastic.

Next steps
First a quick comment; The response above is the initial test, but I am still tweaking the rules. I also need to upload the canonical files to the GPT project. Hope that doesn’t destroy the great results lol – I don’t want to jinx it, so I will leave that here 🙂
Ok according to the original document I was working from to finish this project, my next step is to create a dedicated page for this and the other GPTs that were created. But… I’m thinking about going against the grain here and just adding the links to these in a file I call the dendritic index (which is actually just an index of external sources that are a credible citation or mention (just look in the footer to see it). If I was focused on just SEO AND had the time, I would probably create a dedicated page, but since I’m focusing on the broader ecosystem AND short on time, I’m leaning toward just listing it in my dendritic index. May be I will just sleep on it and decide tomorrow.
Here are screenshots of the results, or at least part of them
