The crawl plan is built from the category and provincia grid rather than from deep pagination. That is deliberate. On a cars index captured on 10 June 2025 the page reported 41 results per page, a ceiling of 200 pages and a result total that saturates instead of counting further, so a broad query cannot be walked to the end. Slicing by category, province and price band keeps each slice under that ceiling.
Milanuncios sits behind a bot wall. Plain HTTP clients get a 403 interstitial rather than a page, so collection runs in a real browser context at a measured rate, and backs off when the site asks it to. We do not attempt to defeat the challenge itself.
Output is limited to listing and commercial data. Seller identifiers can be pseudonymised or dropped entirely on request.
Milanuncios renders its pages on the server and ships the page state as JSON inside the HTML, so a single ad page carries a whole record rather than scattered fragments. On an ad page captured on 6 July 2026 the fields present were these.
We extract that record, flatten the typed attributes into named columns and deliver it as CSV, JSON, XLSX or an API.
The URL grammar is simple and stable. Every path has one or two segments. An ad sits at /{category}/{title-slug}-{nine digit id}.htm. An index sits at /{category}/ or /{category}-en-{place}/, where place is a provincia, or a municipio followed by its provincia. Accents are stripped and multi word provinces take an underscore, so La Rioja becomes la_rioja and Ciudad Real becomes ciudad_real. Keyword landing pages use the same two segment .htm shape but have no trailing id, so the id is what separates a real ad from an SEO page.
Two details catch people out. Province ids in the page data follow Spain's official INE codes, which is convenient once you notice it: Madrid is 28, Ourense is 32, Sevilla is 41, and the data joins straight to public statistics. Less convenient, in bilingual regions a municipality carries both of its names joined by a pipe in the slug, so Alicante appears as alicante|alacant and Crevillent as crevillent|crevillente. Anything keyed on the place string alone will split one town in two.
Ads also expire. Milanuncios states that an expired or deleted anuncio cannot be recovered and has to be published again, which issues a new nine digit id. We therefore track by id and match on seller, title, price and attributes as well, or a relist reads as a new car.
Milanuncios is a Spanish general classifieds marketplace and has been running since 2005. Schibsted Classified Media Spain completed its purchase in 2014, the business passed to Adevinta when that group was spun out in 2019, and it changed hands again when EQT completed the acquisition of Adevinta Spain in February 2026, a deal announced in July 2025. Its stablemates in that Spanish portfolio are Coches.net, motos.net, Fotocasa, habitaclia and InfoJobs. Two older classifieds domains now point at it: checked on 27 August 2026, both vibbo.com and segundamano.es redirect to www.milanuncios.com.
The catalogue is a single tree. A capture from 10 June 2025 lists 17 top-level categories, each with a numeric id and its own path: Motor at /motor/, Inmobiliaria (real estate) at /inmobiliaria/, Empleo (jobs) at /ofertas-de-empleo/, then Servicios, Negocios, Informática, Telefonía, Casa y Jardín, Moda y complementos, Bebes, Juegos, Imagen y Sonido, Formación y libros, Aficiones y ocio, Deportes y náutica, Mascotas y agricultura and Comunidad.
This matters more than it looks. The big verticals are not separate sites with separate rules. A used car, a flat to rent and a job advert sit in the same tree, use the same URL grammar and carry the same core record, so one crawler covers all of them. Ads come from two kinds of seller, shown to users as particular (private individual) and profesional (trade), and Milanuncios runs a separate paid product, Milanuncios Pro, for the professional side.

Teams scrape Milanuncios for three things: what is on the market, what is being asked for it, and who is asking. Private and trade supply share one index, so Milanuncios prices can be read from both sides rather than from dealers alone.
The seller type field is where most motor work starts. Because private and professional are distinct values on every ad, the same model splits cleanly into a private column and a dealer column, and you can watch the gap move by provincia, week over week. Dealer pages help as well: every professional seller has a shop page under /tiendas-profesionales/ with its own numeric id, so one dealer's stock can be followed as units appear, get renewed and drop off.
Price movement is already in the page. Listing cards carry a previous price beside the current one when the seller has cut it, so a drop does not have to be inferred from your own history, although we keep that history too.
And since every ad has both a publication date and a sort date, a genuinely new ad can be told apart from an old one that was simply renewed. That is the difference between measuring supply and measuring seller activity.

If you sell online, run a marketplace, or advise e-commerce clients, you already know why eBay matters: it’s one of the few places where big retailers compete side by side with thousands of small merchants and private sellers.
E-commerce teams do not just need “some” competitor data anymore. They need a continuous stream of real prices, discounts, stock levels, reviews, and seller behavior from the platforms that actually shape their markets.
Amazon provides valuable information gathered in one place: products, reviews, ratings, exclusive offers, news, etc. So scraping data from Amazon will help solve the problems of the time-consuming process of extracting data from e-commerce.
ScrapeIt is a managed web scraping agency. You name the fields and the cadence. We build the crawler, run it, monitor it and repair it when Milanuncios changes its markup, which it does. What you receive is data, not a repository to look after.
Every engagement opens with a sample from a slice you choose, so the columns can be checked against live ads before any schedule is agreed. Scope, frequency and format are settled in writing first.
No. Milanuncios publishes no documented public data API, and its robots.txt disallows the /api/ path outright. A seller facing product called Milanuncios Pro exists for professional advertisers, but that is a tool for managing your own listings, not a feed of the marketplace. One trap if you go searching: in Spanish property, API stands for Agente de la Propiedad Inmobiliaria, a licensed estate agent, so shop names on the site containing API are agencies rather than software. Collecting Milanuncios data means scraping the public pages, which is what we do.
As often as the slice earns. Motor and property move daily and dealer stock rotates continuously, so most schedules run daily or twice daily on the categories that matter and weekly across the long tail. There is a second reason to run daily: an ad can be renewed once a day, which lifts it back to the top of results and resets its expiry, so only a daily read separates genuinely fresh supply from renewed supply. We agree cadence per category rather than applying one interval to everything.
Yes, and without guessing. Every ad carries a seller type field whose value is private or professional, the two sides Milanuncios shows to users as particular and profesional. Professional sellers also get a shop page under /tiendas-profesionales/ with its own numeric id, so their ads group cleanly by dealer. On the first page of a cars index captured on 10 June 2025, 32 of the 42 ad records were professional and 10 were private, a fair warning that a casual sample of Milanuncios is not a sample of private supply.
It leaves the search results and its URL stops serving the ad. Milanuncios states that an expired or deleted ad cannot be restored and has to be published again, and a republished ad receives a new nine digit id. That has a practical consequence for anyone measuring time to sale, because the id alone will not link a relisted item back to the original. We keep the last good snapshot of every ad we have seen, so a disappearance is recorded as an event rather than quietly vanishing from your file.
Not by default. The output is limited to listing and commercial data: title, description, price, location, dates, category, attributes, images and seller type. Where a seller identifier is needed to group a dealer's stock, it can be pseudonymised or excluded on request. Descriptions are free text and private sellers sometimes type a phone number into the body, so that text is filtered before delivery, and we leave the contact endpoints alone - Milanuncios keeps seller email addresses hidden from other users and puts its own contact paths behind a robots.txt disallow. Personal data in the EU falls under the GDPR; we scope collection to what you actually need, and you should take your own legal advice on your intended use.
