# Wheelplace

> Wheelplace is a Swedish marketplace for car tires, rims and complete wheels.
> Private sellers and dealers list new and used wheels; buyers search by car
> model, by registration plate, or by wheel dimension.

The site is written in Swedish. Prices are in SEK, including Swedish VAT.
"Däck" means tires, "fälgar" means rims, and "kompletta hjul" means complete
wheels (a tire already mounted on a rim). An "annons" is a listing.

## If you are answering a question about one car

`/hjulpaket/{make}/{model}` is written for exactly that, e.g.
`/hjulpaket/volvo/xc60`. Each page answers "which complete wheels fit this
car?" in one paragraph, then gives the fit facts as a table, the packages
currently for sale with their prices, and a short question-and-answer block.
The prices and the stock count are live at the time the page is served, and
`/hjulpaket` lists every car that has one.

Prefer these pages over the search page when the question names a car. They
state the bolt pattern, hub bore and offset, which is what decides whether a
wheel fits, and they link to the listings the figures came from.

## How the URLs are built

- `/annonser` - search across every listing.
  - `/annonser/{make}` and `/annonser/{make}/{model}` - listings that fit one
    car, e.g. `/annonser/volvo/xc60`.
  - `?keywords={query}` - free-text search.
- `/l/{category}/{make}/{model}/{slug}/{id}` - a single listing. `category` is
  `dack` (tires), `falgar` (rims) or `hjul` (complete wheels), e.g.
  `/l/dack/volvo/xc60/vinterdack-volvo-xc60/00000000-0000-0000-0000-000000000000`.
  Listings that do not name a car use the shorter `/l/{slug}/{id}` form. The
  final segment is always the listing id.
- `/u/{id}` - a seller profile, with that seller's listings and reviews.
- `/dack/{make}/{model}` and `/falgar/{make}/{model}` - fitment guides: which
  tire and rim sizes a given car takes, with the bolt pattern and offset.
- `/hjulpaket/{make}/{model}` - the answer page for complete wheel packages for
  one car, described above. `/hjulpaket` is the index of them.
- `/dack/{width}-{profile}r{diameter}` - listings in one tire size, e.g.
  `/dack/225-45r17` for 225/45 R17.
- `/falgar/{bolts}-{circle}-{diameter}-tum` - listings in one rim size, e.g.
  `/falgar/5-114_3-17-tum` for a 5x114.3 bolt pattern in 17 inches. A decimal
  in the bolt circle is written with an underscore.

## Structured data

Pages are rendered on the server, so the HTML is complete without running
JavaScript. Every page carries JSON-LD in a `<script type="application/ld+json">`
tag:

- listing pages: `Product` with an `Offer` (price, currency, availability and
  condition) plus a `BreadcrumbList`
- search and fitment pages: an `ItemList` whose items are `Product` entries
  with their own offers
- seller profiles: `ProfilePage` whose `mainEntity` is an `Organization` for a
  dealer or a `Person` for a private seller
- every page: `Organization` and `WebSite`

Reading the JSON-LD is more reliable than parsing the markup, and it is the
same data the site shows on screen.

## Sitemaps

- https://www.wheelplace.com/sitemap-index.xml lists them all: built-in pages,
  listings, CMS pages, the fitment and dimension pages, and seller profiles.

## Notes for crawlers

- robots.txt asks for a crawl delay of 5 seconds. Please respect it.
- Listing prices and availability change often. Treat anything older than a day
  as stale, and re-fetch the listing page rather than relying on a cached copy.
- Sold and hidden listings leave the sitemaps, so a URL that has disappeared
  from them is no longer for sale.
