## URL structure

- Category hierarchy:
  - /[category]/...
  - Nested category levels may exist beyond two levels

- Region pages:
  - /[category]/.../[region]/
  - Example: /realestate/tobago/

- City pages:
  - /[category]/.../[region]/[city]/

- Listing pages:
  - /adv/[id]/
  - Listing pages are individual classified ad pages

- Filter structure:
  - Filters are implemented as path segments using the pattern:
    /[filter-name]---[value]/
  - Example: /color---14/
  - Example: /condition---1/
  - Region or city always appears at the end of the category path, before any filters

## Pagination

- Pagination is implemented using the `page` query parameter
  - Example: /realestate/?page=2

- Pagination pages represent continuation of listing results and do not contain unique content
- URLs with pagination parameters should not be treated as primary pages

## Geo pages

- Geo pages are region-specific or city-specific versions of category and nested category pages
- Region pages use the pattern:
  - /[category]/.../[region]/
- City pages use the pattern:
  - /[category]/.../[region]/[city]/
- Geo pages may be indexed when they represent meaningful local inventory
- Do not list all geo pages in this file
- Geo pages follow the same pagination, filter, canonical, and duplicate rules as other listing pages

## Mobile version

- Mobile pages are available under the `m.` subdomain
  - Example: https://m.pin.tt/realestate/

- Mobile pages contain the same content as the main domain
- Mobile pages should be treated as duplicates of the corresponding main-domain pages
- The canonical version is always the main domain: https://pin.tt/
- Do not treat mobile URLs as separate primary pages

## Technical parameters

- Some URLs include technical or service query parameters that do not change the core content of the page

- Examples:
  - ?lat=
  - ?lng=
  - ?radius=
  - ?saved_search=
  - ?p=
  - ?city=

- URLs that differ only by technical parameters should be treated as duplicates of the base URL
- Technical parameters should not be used to define unique or indexable pages
- Ignore technical parameters when determining page uniqueness or canonical versions

## Allowed for indexing

- / : Home page
- /[category]/... : Category and nested category pages
- /[category]/.../[region]/ : Region pages
- /[category]/.../[region]/[city]/ : City pages
- /[category]/.../[single-filter]/ : Pages with exactly one filter segment
- Listing pages

## Disallowed for indexing

(Refer to robots.txt for full technical restrictions.)

- System and service pages
- Mobile subdomain pages
- URLs where the same filter segment appears more than once
  - Example: /color---14/color---15/
- URLs containing three or more filter segments
  - Example: /color---14/condition---1/brand---5/
- URLs with sorting or ordering patterns
- URLs with technical or service query parameters
- Duplicate or faceted navigation pages that create non-unique content

## Canonical and duplicate logic

- Category and nested category pages without filters are primary
- Region pages are canonical within their regional scope
- City pages are canonical within their city scope
- Pages with exactly one filter segment are valid but secondary
- Pages with two filter segments are considered limited variations and should not be treated as primary
- Pages with three or more filter segments are non-canonical
- Pagination pages are duplicates of the corresponding base, region, city, or filtered page
- Mobile URLs are duplicates of their corresponding main-domain pages
- URLs that differ only by pagination, sorting, technical parameters, or filter combinations represent variations of the same base entity
