What Goldie Bench Actually Measures
Read the scores for what they are before applying them to SEO.
The Goldie Bench tasks page describes 50 one-shot creative coding tasks across five categories, each sent to every model with the same prompt and scored 0–10.
There is no Goldie Bench task for writing SEO briefs or schema, so no score here tells you which model writes the best brief.
The closest match is the Page category, where models build marketing pages in one shot.
Landing Pages: The Closest Test To Service Pages
On the Landing task page, the average score is 8.11/10, with 21 of 26 attempts scored.
| Model | Landing score | Page read |
|---|---|---|
| Fugu Ultra | 9.0/10 (winner) | /tasks/landing |
| Fusion | 9.0/10 | /tasks/landing |
| GLM-5.2 | 9.0/10 | /tasks/landing |
| Grok | 9.0/10 | /tasks/landing |
| GPT-5.6 Sol | 8.7/10 | /tasks/landing |
| Gemini 3.6 Flash | 8.6/10 | /tasks/landing |
| Claude Fable 5 | 7.2/10 | /tasks/landing |
For an SEO team, a strong landing score means a faster first draft of a service page layout.
It says nothing about whether the copy answers a buyer's question, which is the part that matters for ChatGPT.
Promo Pages And The Overall Leaderboard
The Aipbpromo task, a one-shot motion-graphics advert page, averages 7.48/10; Qwen 3.8 is listed as the winner and GPT-5.6 Sol scores 8.3/10 for second.
On the overall leaderboard, Fusion leads with an 8.59 average, Claude Opus 5 is second at 8.27 and GPT-5.6 Sol is fourth at 8.16, tagged best at Pages.
The Claude Opus 5 model page lists an 8.27/10 average across 50 tasks with 13 gold medals.
Use these as a rough guide to which models build pages well, not as an SEO ranking.
Which Models To Use For Which ChatGPT SEO Task
| Task | Model help | Human part |
|---|---|---|
| Service page layout | Start with a high Landing scorer from the table | Check copy, facts and claims |
| Content brief | Any top leaderboard model can draft; no bench task scores this | Pick the questions buyers really ask |
| Organization schema draft | Model drafts the JSON-LD; no bench task scores this | Match it to your real business facts |
| Robots.txt review | Model reads the file and flags rules | Check CDN rules and server logs |
| Outreach research | Model builds a draft list | Approve every pitch; send nothing automatically |
The Parts No Model Score Covers
OpenAI's ChatGPT search help page sets the hard rule: allow OAI-SearchBot and let OpenAI's published IP ranges through your host or CDN.
The OpenAI crawler overview adds that robots.txt changes take about 24 hours to reach search, and that GPTBot is a separate training crawler.
Google's page on hiring an SEO says no one can guarantee a #1 ranking, and OpenAI says ChatGPT placement is not guaranteed either.
Earned mentions, a consistent brand story and the decision of what to publish first are judgement calls that sit with people.
Bing's Webmaster Guidelines say GEO does not guarantee citations in AI answers, which is worth reading before any agency call.
Worked Example: A SaaS Founder Splitting The Work
- The founder asks a high Landing scorer to draft a comparison page layout, then rewrites the copy around real customer questions.
- A leaderboard model drafts Organization markup; the founder checks every field against the company's own facts.
- The founder confirms OAI-SearchBot gets 200 responses in the server logs.
- The agency handles mentions on industry sites, with any paid placement marked
rel="sponsored"per Google's link qualification guide. - Each month, the founder reviews chatgpt.com referrals, which in our own analytics usually arrive tagged utm_source=chatgpt.com.
If you want to run that model work yourself, the AI Profit Boardroom shows how.
