Solano CF — Subdomain vs Sub-Section Pros & Cons

Jan's question: Should the new Solano site be a separate domain (solano.californiaforever.com) or a sub-section of the main site (californiaforever.com/solano/)?

Sub-Section (californiaforever.com/solano/)

Pros

  1. SEO compounding — All campaign traffic builds authority for one domain. Solano pages benefit from the main site's existing authority from day one. No keyword cannibalization between two sites competing for the same terms.
  2. No content duplication — Newsletter, news (just tag "local"), Break Ground, endorsements — all one system, one entry point. Jan's 6 requirements are mostly already built on the main site or easily added.
  3. Scales for future regions — If they ever do this for another area, it's just another section. Subdomains mean spinning up whole new WP installs each time.
  4. One codebase — One theme, one set of plugins, one maintenance burden. No content drift between two installs.
  5. Jan already wants to reuse the main site's design — Why maintain two themes that look the same?

Cons

  1. Nav/UX complexity — Need section-aware navigation so Solano visitors don't see Foundry/Shipyard stuff. Solvable but requires design work.
  2. Tone clash — Solano content is fact-based and locally defensive. Main site is aspirational and vision-forward. Need clear section boundaries.
  3. Coupled deployments — Any sitewide change (plugin update, design tweak) could ripple into campaign pages.

Separate Domain (solano.californiaforever.com)

Pros

  1. Campaign isolation — 100% focused landing experience for ad traffic. Solano residents see only content about them. No risk of wandering into corporate pitch deck content.
  2. Speed to launch is actually slower — The current Solano theme is block-based (WordPress blocks) and the client wants a completely new design direction. Retrofitting a block theme isn't viable — this would mean developing an entirely new theme from scratch, which is more time-intensive than adding a section to the existing main site.
  3. Editorial independence — Different stakeholders, different approval chains. CF marketing team can move fast without worrying about breaking the main site.
  4. Cleaner analytics — Separate GA property, no segment filtering needed. Straightforward campaign attribution.
  5. Messaging firewall — If something controversial happens with the main brand, the Solano site isn't visually connected. Matters for a politically sensitive local campaign.
  6. Print-friendly URL — solano.californiaforever.com on a postcard reads as "this is your site" to a local audience.

Cons

  1. SEO split — Google treats subdomains as separate sites. Campaign traffic builds authority for an isolated domain instead of strengthening the main property.
  2. Content duplication burden — Newsletter, news, Break Ground, endorsements all need to exist in two places. Every update happens twice or you build sync tooling.
  3. Maintenance multiplied — Two themes, two WP installs, two plugin sets. Content drift is inevitable as both sites grow.
  4. Keyword cannibalization — Both sites competing for "California Forever jobs," "Suisun Expansion Plan," etc.
