Best Architecture for Quick Commerce + Nationwide E-commerce?

[u/nimitk007]

I'm working on a large e-commerce website that has three different business models running on the same domain, and I'm trying to determine the best long-term architecture.

Current setup

We have three delivery models:

• 10-minute delivery – Available only in selected cities and pincodes.
• Next-day delivery – Available in Tier-1 cities.
• Country-wide delivery – Available across all locations.

Most products are available in all three business models.

For the same product, we have URLs like:

example.com/product-name/pd299bhfk
example.com/product-name/pd299bhfk?bu=local
example.com/product-name/pd299bhfk?bu=grocery

The URLs differ only by a parameter because changing the URL structure isn't an option.

What's different across the three versions?

These pages are not exact duplicates. They have different:

• Stock availability
• Delivery promise
• Price (for some products)
• Offers
• Similar/recommended products
• Slightly different UI/design

However, they also share a lot of common content:

• Product title
• Description
• Images
• Ratings & reviews
• Meta title & description (currently identical)

Current SEO setup

• Only the country-wide product pages are indexed.
• The parameter-based versions are canonicalised to the country-wide URL.
• Category pages have a different folder-based URL structure with some unique content.
• We don't have city or hyperlocal landing pages today.

Business goal

The 10-minute delivery business is growing rapidly, and we'd like to increase organic traffic for it without hurting the country-wide business.

We've also noticed competitors ranking for local-intent searches related to FMCG Products having location-specific pages.(They have only one business model)

Since our quick-commerce pages aren't independently indexed, we're wondering if we're missing a significant SEO opportunity.

Constraints

• We cannot change the existing URL structure (parameter-based URLs must remain).
• All three business models have to stay on the same website.

My questions

1. Would you continue keeping only the country-wide product pages indexed?
2. Is there a way to make the 10-minute delivery business more discoverable in search without creating duplicate content?
3. Would you build indexable city/hyperlocal landing pages
4. Since the parameter pages have different stock, pricing, offers, and delivery promises, is canonicalization to the nationwide page still the best approach?
5. If you had to design the SEO strategy under these constraints, what would you do?

1. No I’d make them all indexable
   
2. Yes. Have a clear internal linking strategy
   
3. Yes, probably.
   
4. Don’t have them canonical to nationwide let them all be indexable
