Practical Gemini prompts and workflows to generate brand-aligned domain name ideas, filter availability, and set naming governance rules.

Hook: Stop wasting time on random name lists — get brand-aligned domains faster with Gemini Guided Learning

Marketers and product teams spend hours scrolling naming sites, checking registrars/APIs, and juggling spreadsheets — only to end up with long lists of unfit names. The result: missed launches, overpaid purchases, and fractured brand identity across domains and social handles. In 2026, you can do better. Gemini Guided Learning lets you run focused, iterative naming workshops with AI that enforces your brand rules, prioritizes technical viability, and outputs ready-to-act lists.

The big picture (most important first)

Use Gemini as a naming teammate that:

Generates targeted seed lists based on brand signals you define (audience, tone, vertical, constraints).
Applies governance rules (length, character sets, trademark heuristics, TLD preferences) during generation rather than as an afterthought.
Integrates with workflows — availability checks, DNS templates, registrar cart pre-fills and simple scripts for CI/CD deployment.

Below are three practical ways to use Gemini Guided Learning to do this — each with exact prompt templates, iterative workflows, governance rule examples, and automation touchpoints you can implement today.

Why this matters in 2026

In late 2025 and early 2026 we saw two important shifts: LLMs moved from one-off creative prompts to guided learning experiences that preserve session memory and teach by iteration; and registrars/APIs expanded programmatic checkout and DNS automation. That combination means an AI can now help you discover names and also help you operationalize them — which is the difference between a cool idea and a launch-ready domain portfolio.

Way 1 — Guided Discovery: Seed, Score, Refine

Goal: Produce a focused list of 50–200 candidate domains that match brand voice and basic availability heuristics.

Step-by-step workflow

Define brand signals: audience, tone, keywords, disallowed words, preferred TLDs.
Run a structured Gemini session that outputs seeds in grouped buckets (literal, metaphorical, compound, short nouns).
Ask Gemini to score each seed on memorability, pronounceability, and length.
Iterate by filtering by score and requesting compact variants.

Practical prompt — initial seed generation

Use this as a starter in Gemini Guided Learning. Tell it to act as a naming expert and return a strict JSON list to make automation trivial.

Prompt:
Generate 80 candidate domain name seeds for a B2B developer tool that simplifies multi-cloud DNS automation. Brand signals:
- Audience: DevOps and platform engineers at mid-to-large companies
- Tone: technical, reliable, concise
- Must be noun-based or compound noun (no verbs)
- Preferred TLDs: .dev, .cloud, .io. Exclude .com for initial exploration
- Maximum 12 characters for the left-hand label (before the dot)

Return JSON array of objects: {"name": "", "type": "literal|metaphor|compound|short", "length": int, "notes": ""}. No commentary.

Why this works: Asking for JSON and precise constraints forces Gemini to produce structured, machine-readable output you can programmatically evaluate and feed into JSON/YAML workflows and availability checks or spreadsheets.

Iteration: narrow by scoring

Take the JSON output and ask Gemini to apply a scoring rubric. Example scoring rules:

Memorability (1–5): fewer syllables and uniqueness score
Pronounceability (1–5): common phoneme sequences
Brand fit (1–5): technical vs. playful alignment

Prompt:
Score each name from the previous JSON on Memorability, Pronounceability, and BrandFit. Return the original JSON with three new integer fields: memorability, pronounceability, brandFit. Add a computed field "composite" = average of the three scores.

Then filter locally or ask Gemini to return the top 30 by composite score. This is an effective two-stage approach: creative breadth, then signal-based narrowing. Use instrumentation and guardrails (for example, query limits and audit logs) to keep scoring consistent — see examples on instrumentation to guardrails.

Way 2 — Naming Governance as You Generate

Goal: Bake governance rules into generation so outputs are launch-ready and compliant with your legal and brand policies.

Common governance constraints to encode

Maximum left-hand label length (e.g., 12 chars).
No hyphens or numbers (or allow single-digit suffixes only).
Blacklist: competitor names, existing product names you must avoid, trademark watch terms.
TLD policy: preferred-first and forbidden TLD lists.
Social handle availability preference: short handle under 15 chars.

Practical prompt — enforce rules in generation

Prompt:
You're the team's Naming Officer. Generate 60 domain candidates that obey these governance rules exactly:
- Left-hand label max 12 characters, letters only unless a single digit suffix (e.g., app2)
- No hyphens
- Do not include these blacklist words: [alpha, beta, competitorX, legacy]
- For each candidate, list preferred TLDs (in order), whether social handle @name is likely available (yes/no/guess), and risk flags (trademark, ambiguous meaning). Output strict JSON.

Return objects: {name:"", tlds:[".dev"], socialGuess:"yes|no|maybe", riskFlags:[]}

Gemini Guided Learning sessions can preserve these constraints across iterations. If you refine the brand voice later, the session remembers earlier rules and applies them. For legal or procurement concerns, tie shortlisted names to an operational procurement playbook so legal and purchasing get a reproducible brief.

Sample naming governance rules you can copy

Primary rule: Left-hand label <=12 chars, ASCII letters only unless single digit suffix.
Secondary rule: Avoid dictionary words that are trademark-heavy in our vertical (run checks via trademark APIs for shortlisted names).
TLD policy: .dev and .cloud preferred, .io allowed for developer-facing products, country-code TLDs allowed only after manual review.
Social sync: require a matching Twitter/X or Mastodon handle or alternative within one character difference.

Pro tip: Use Gemini to output regex-ready filters (for example: ^[a-z]{3,12}[0-9]?$) and run candidates through them automatically.

Way 3 — Integration: From Name Ideas to Actionable Checklists and Scripts

Goal: Move from ideation to execution. Use Gemini to generate availability-check scripts, registrar API payloads, DNS templates, and a naming policy document you can ship to legal and procurement.

Automation touchpoints

Registrar/API pre-check: generate curl or Python scripts for Namecheap, Cloudflare, or GoDaddy APIs.
DNS and TLS templates: produce a reproducible DNS record set and Terraform snippets for Cloudflare DNS or AWS Route 53.
Procurement-ready package: a short report with top 10 names, trademark risk summary, projected CPC and aftermarket risk.

Practical prompt — availability + automation

Prompt:
Take the top 20 candidate names from our session. For each name generate:
- Registrar availability check script in Python for the Cloudflare API (assume API keys are env vars)
- Terraform snippet to provision an A record, CNAME for www, and an automatic Let's Encrypt certificate (use example placeholders for IPs)

Return a zip-friendly JSON with keys: name, availabilityScript, terraformSnippet.

Gemini can produce ready-to-run code that you or an engineer can quickly adapt. In my experience, small edits are needed (API paths change), but the heavy lifting is done and saves hours. Keep availability checks and scheduled re-checks as part of your continuous monitoring practice so names aren’t claimed between shortlist and procurement.

Prompt engineering patterns that work for naming

When you use Gemini for domain ideation, follow these patterns:

Start with structured outputs: JSON or CSV makes downstream automation trivial.
Be explicit about negative constraints: list banned substrings, lengths, and TLDs.
Iterate with scoring: generate broadly, score with a rubric, then ask Gemini to refine the top N.
Preserve context: use the Guided Learning session memory to carry constraints across prompts so the model learns your brand rules. Persist session artifacts like examples and small datasets in a micro-app or template pack such as the Micro-App Template Pack.
Use role-based prompts: "Act as a trademark analyst" versus "Act as a creative namer" to get different perspectives in the session.

Example mini-case: Launching "Nimbus" (fictional) using this process

Scenario: Nimbus is a platform engineering startup building a multi-cloud DNS controller. They need a short, technical, noun-based domain, prefer .dev or .cloud, and must avoid names close to cloud provider trademarks.

Session highlights

Seed generation prompt returned 120 names across four buckets: literal (dnsforge.dev), metaphor (cumulus.cloud), compound (routegrid.dev), short (nbx.dev).
Score step filtered to 28 names with composite >=4.
Governance rules removed names within two characters of major cloud trademarks and banned hyphens/numbers.
Gemini produced availability scripts and a Terraform template for the top 10. Two names passed trademark quick-check heuristics and procurement favored one: routegrid.dev.

Outcome: From zero to a procurement-ready package in less than a business day with a developer-ready Terraform snippet to provision DNS and TLS. That velocity matters in competitive verticals.

Advanced strategies and future-proofing (2026 and beyond)

As LLMs and guided learning evolve, integrate the following into your naming practice:

Continuous monitoring: Hook Gemini sessions into scheduled runs that re-check availability and monitor aftermarket alerts for shortlisted names.
Metricize preference: Keep a small dataset of accepted vs. rejected names and use it as few-shot examples in future sessions so Gemini learns your team's taste.
Cross-channel checks: Ask Gemini to simultaneously evaluate social handle availability, SEO risk (search confusion), and semantic drift in 12- and 24-month windows.
Governance-as-code: Store your naming rules as JSON/YAML and have Gemini apply them programmatically across product teams.

Limitations and guardrails

Gemini is powerful, but it isn’t a legal advisor. For high-value purchases (six figures or above) always run formal trademark and legal clearance. Use Gemini to triage and prepare the brief for counsel, not to replace counsel. Also test generated scripts and Terraform in a safe sandbox — APIs and provider behavior change.

Actionable checklist — copy and run

Create a Guided Learning session and load these constraints: audience, tone, banned words, TLDs, length limit.
Run seed generation with JSON output (80–120 names).
Score and filter top 30 using memorability/pronounceability/brandFit.
Run governance-enforced generation to replace or refine failing names.
Generate availability scripts and Terraform DNS/TLS snippets for top 10.
Package top 3 candidates into a procurement-ready brief with risk flags and social handle checks.

Why this approach wins

It replaces ad-hoc brainstorming with a repeatable, auditable process that connects creative naming with operational readiness. In 2026, the technical and brand sides of domain selection must be aligned — and Gemini Guided Learning is uniquely positioned to hold both perspectives during a naming project.

Final notes: prompts to save right now

Store these three prompt templates in your team knowledge base:

Seed JSON generator (structured candidates)
Scoring and composite filter (memorability, pronounceability, brandFit)
Governance enforcer + automation pack (regex filters, API scripts, Terraform snippets)
