SEO: Multi-Domain Brand Search

When a company has multiple domains (e.g., company.com and product.ai), ensure the company/main site ranks first for brand queries. Product sites focus on product keywords and do not compete for brand position. See domain-architecture for structure decisions; rebranding-strategy for domain change and migration.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Typical Scenarios

Scenario	Description
Multiple domains	Company main site (company.com), product site (product.ai / product.io)
Brand query competition	Product site or third-party (Crunchbase, LinkedIn, reviews) may outrank main site for brand
Entity confusion	Legacy brands, sub-brands, directories dilute brand perception
Goal	Brand queries → company.com first; product.ai → product keywords only

Hub-Spoke Model

Role	Domain	Responsibility
Hub	company.com	Brand #1; About, Research, ecosystem, product matrix
Spoke	product.ai	Product keywords, features, pricing; visible "by [Company]" and link back to company.com

Differentiation

Dimension	Hub (company.com)	Spoke (product.ai)
Audience	Investors, partners, media, developers	Product users, prospects
Keywords	Brand name, company name, industry	Product features, use cases
Content	Mission, About, Research, Events, product matrix	Features, Use Cases, Pricing, Sign up
Conversion	Contact, Waitlist, Early Access	Sign up, Try free, Pricing

Avoid Cannibalization

• Hub does not target Spoke product keywords (e.g., "virtual staging," "AI design tool")
• Spoke does not target Hub brand keywords (Title avoids brand-only; add product description)
• Internal links: Hub → Spoke (Products); Spoke → Hub (About, Footer)

Optimization Checklist

Hub (company.com) On-Page

Item	Recommendation
Title	Company full name + positioning, e.g. [Company] — [Slogan] | AI Research & Products
Meta Description	Company name, core business, partners; 150–160 chars
H1	Company name or main slogan
URL	Canonicalize www vs non-www (301)

Hub Content & Structure

Item	Recommendation
About	Company intro, founders, founding date, positioning; link to product sites
Products	Product matrix; each product links to its site
Research / News	Papers, events, partnerships; increase brand mentions
FAQ	"What is [Company]?" "What is [Product]?"; FAQ schema

Spoke (product.ai) Differentiation

Item	Recommendation
Title	Product name + product description, e.g. [Product] — [Core function] or [Product keyword] | [Product]; avoid brand-only
About	"A product of Company"
Footer	"© [Company]" or "A [Company] Product" + link to company.com
Schema	SoftwareApplication with author or publisher pointing to Company

Schema (Hub)

Use Organization schema with subOrganization to define product relationships:

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "[Company Name]",
  "url": "https://www.company.com",
  "description": "[Company description]",
  "sameAs": ["https://linkedin.com/company/...", "https://github.com/..."],
  "subOrganization": [
    {
      "@type": "SoftwareApplication",
      "name": "[Product Name]",
      "url": "https://product.ai",
      "applicationCategory": "[Category]"
    }
  ]
}

Entity & Knowledge Panel

See entity-seo for full entity optimization. Key for multi-domain:

• Consistency: Same brand name, description, logo across Hub and Spoke
• Entity Home: Authoritative About page on Hub as primary reference
• Knowledge Panel: Claim via Google; suggest updates when available

Output Format

• Hub vs Spoke mapping (domains, roles)
• On-page checklist (Hub and Spoke)
• Schema (Organization with subOrganization)
• Internal linking plan
• Cannibalization check
