YML Feeds FAQs

What requirements should the product page meet so that the crawler can index the information provided?
The product page must be available, return the HTML code, and must contain the necessary information about the product offer. To ensure correct definition, the product page must contain the valid Schema.org Product or Open Graph Product microdata. In order to determine the data type and to process the information about the product offer in the Schema.org Product markup, the offers property of the Offer or AggregateOffer type must be present. Pages that are marked using the Open Graph protocol must contain the "og:type" tag with the "product" value.

Microdata should be used on all product offer destination URLs in order for our crawler to be able to process data correctly. Only one Product item corresponding to the product offer for the URL should be placed on the destination pages.

In the absence of microdata, crawler tries to automatically detect the data about the product offers using a special algorithm of web pages analysis. However, this may not always ensure that you receive the correct data. We recommend using content microdata by Schema.org to achieve better results.

If your website does not use product markup and is not compatible with advanced extraction algorithms - you can create a feed with a prepared CSV-file.

What data about the product is indexed by the crawler?
The following properties for products are indexed: name, short description, product price, currency of price offer, information about the availability of the product offer, link to the image.
Special features of processing products belonging to Car Tires and Wheels
For products that can be assigned to this category, the min-quantity parameter is added. This item indicates the minimum number of units to order.
An example of specifying the ability to order only in pairs:

You can override this value in the handler settings, the possible values are:
  • 1 Piece - sale by piece
  • 2 Piece - sale in pairs
  • 4 Piece - sale in sets

The absence of a min-quantity item means that the min order quantity is 1 piece. This item doesn't apply to any other product categories.
Special features of processing products belonging to Clothing and Shoes
In addition to the data that can be presented with the help of microdata, the crawler will try to highlight the necessary characteristics of the product offers, applying the algorithm of additional analysis.
The algorithms that are used to extract product characteristics are completely unified and automated.
An example of specifying product parameters in a feed:
    <param name="Size" unit="INT">L</param>
    <param name="Color">Multicolor</param>
Features of clothing size determination
By analyzing clothing and footwear products, the robot compares the data obtained with the most common dimensional grids.
Universal international size designations: XXS, XS, S, M, L, XL, XXL, 3XL
International kids size designations: 0-3m, 3-6m, 6-9m, 9-12m, 12-18m, 18-24m, 24-36m
International bra sizes: A, AA, B, C, D, DD, DDD, DDDD, E, F, FF, G, GG, H, HH, J, JJ, K, KK, LL
Numeric size designations, common in Europe, Russia and the CIS.
An example of specifying a size in a product feed:
    <param name="Size" unit="INT">XL</param>

For jeans, common inch markings can also be defined (for example: 31/32)
An example of jeans size designation in a product feed:
    <param name="Size" unit="INCH">30/32</param>

For children's clothing, numerical designations of size relative to height can also be defined.
An example of clothing size based on a child’s height in a product feed:
    <param name="Size" unit="Height">104</param>
Color detection features
When analyzing product offerings, the indicated color names are compared with certain Yandex-Market technical requirements with a list of acceptable values: beige, white, turquoise, burgundy, blue, yellow, green, golden, brown, red, olive, orange, multi-colored, pink, red, lime , silver, gray, blue, lilac, purple, khaki, black.
Color definitions that do not match the listed values will be ignored.
An example of specifying color in a product feed:
    <param name="Color">Green</param>
What microdata properties does the generator handle?
The generator processes the Schema.org data for the products:
  • name — product name. Specified as the Product property.
  • description — product description. Specified as the Product property.
  • image — link to the product image. Specified as the Product property.
  • price — price. Specified as the Offer property.
  • lowPrice — minimum price. Specified as the AggregateOffer property.
  • priceCurrency — currency. Specified as the Offer property. To specify the currency, you must use the currency codes according to ISO 4217.
  • priceSpecification — Specified as the Offer property.
  • availability — product availability flag. Specified as the Offer property.
  • category — category name. Specified as the Product property.
  • brand - Specified as the Product property.
Example of Schema.org markup application for a product offer:
<div itemscope itemtype="http://schema.org/Product">
  <h1 itemprop="name">Offer</h1>
  <a itemprop="image" href="http://youwebsiteurl/pictures/thumbnail.jpg">
    <img src="/pictures/thumbnail.jpg" />
  <div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
    <meta itemprop="price" content="1000.00" />
    <meta itemprop="priceCurrency" content="USD" />
    <meta itemprop="availability" href="http://schema.org/InStock" />
  <div itemprop="description">Best offer</div>

Structured Schema.org data for automatic processing is also available in a JSON-LD object. Example of placing data in a JSON-LD object:
<script type="application/ld+json">
  "@context": "http://schema.org/",
  "@type": "Product",
  "name": "Offer",
  "image": "http://youwebsiteurl/pictures/thumbnail.jpg",
  "description": "Best offer",
  "offers": {
    "@type": "Offer",
    "priceCurrency": "USD",
    "price": "1000.00",
    "availability": "http://schema.org/InStock"

The generator processes Open Graph data for the products:
  • og:title — product name.
  • og:description — product description.
  • og:image — link to product image.
  • product:price:amount — price.
  • product:price:currency — currency. Currency codes must conform to ISO 4217.
  • product:sale_price:amount — the sale price of the product.
  • product:availability — availability of the product.

Example of applying Open Graph markup for a product offer:
    <meta property="og:type" content="product" /> 
    <meta property="og:title" content="Offer" /> 
    <meta property="og:description" content="Best offer" />
    <meta property="og:image" content="http://youwebsiteurl/pictures/thumbnail.jpg" />
    <meta property="product:price:amount" content="1000.00" />
    <meta property="product:price:currency" content="USD" />
    <meta property="product:availability" content="in stock" />
Processing of microdata of the products which has reduced price
Two types of prices can be indicated in the Product feed: the regular (old) price (<oldprice> element) of the product and the current reduced price. This information can be identified using Schema.org microdata or Open Graph.
An example of Schema.org markup using the priceSpecification element:
<div itemscope itemtype="http://schema.org/Product">
  <h1 itemprop="name">The Best Product Name</h1>
  <div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
    <strike itemprop="price">1000.00</strike>USD
    <meta itemprop="priceCurrency" content="USD" />
    <span itemprop="priceSpecification" itemscope   
        <strong itemprop="price">900.00</strong>USD
        <meta itemprop="priceCurrency" content="USD"/>
        (Offer valid until 2029-01-12)
        <meta itemprop="validThrough" content="2029-01-12T00:00:00"/>

An example of Open Graph markup using the sale_price element:
    <meta property="og:type" content="product" /> 
    <meta property="og:title" content="The Best Product Name" /> 
    <meta property="product:price:amount" content="1000.00" />
    <meta property="product:price:currency" content="USD" />
    <meta property="product:sale_price:amount" content="900.00" />
    <meta property="product:sale_price:currency" content="USD" />
Getting the name of product categories
In the handler settings, the option of automatically determining the category of goods is available. Our crawler can detect data on category names in several types of Schema.org micromarking: Product, Breadcrumb and BreadcrumbList.
An example of specifying a category as the Schema.org Product property on the product offer page:
<div itemscope itemtype="http://schema.org/Product">
    <meta itemprop="category" content="Best products" />

An example of specifying a category as Schema.org Breadcrumb:
<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
 <a href="http://website.tld/catalog" itemprop="url">
   <span itemprop="title">Catalog</span>
 </a> ›
<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
 <a href="http://website.tld/catalog/group_1" itemprop="url">
   <span itemprop="title">Commodity group 1</span>
 </a> ›
<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
 <a href="http://website.tld/catalog/group_1/best" itemprop="url">
   <span itemprop="title">Best products</span>

An example of specifying a category as Schema.org BreadcrumbList:
<ul itemscope itemtype="http://schema.org/BreadcrumbList">
  <li itemprop="itemListElement" itemscope
    <a itemprop="item" href="https://website.tld/catalog">
        <span itemprop="name">Catalog</span>
    <meta itemprop="position" content="1" />
  <li itemprop="itemListElement" itemscope
    <a itemprop="item" href="https://website.tld/catalog/best">
        <span itemprop="name">Best products</span>
    <meta itemprop="position" content="2" />
Where can I learn more about Schema.org and Open Graph data for products?

If the product offer pages use both the Schema.org and Open Graph markup simultaneously, the data contained in the Schema.org microdata has a higher priority. In case of absence or presence of empty properties in Schema.org, but if they exist in Open Graph - these values will be used.

How to check microdata on the pages of my online store?
You can check the correctness of filling Schema.org microdata using the Markup validation tool.
How are empty microdata properties handled?
Обратите внимание: стандарт YML регламентирует порядок следования элементов и не допускает использования элементов с пустыми значениям. В соответствии с данными требованиями стандарта YML, в случае обнаружения пустых свойств в разметке, они будут обработаны следующим образом:

Required items:
  • Name property (product name) - the product item will be ignored.
  • Price property (product price) - the product item will be ignored.
Необязательные элементы (формируются при наличии соответсвующих опций):
  • Свойство description (описание товара) - заменен на значение элемента name (название товара).
  • Свойство picture (изображение товара) - проигнорирован при формировании файла.
How can I speed up website indexing?
Try to prevent from indexing as many information pages as possible (e.g. articles, reviews, and other similar pages). In this case, the crawler will not waste time on their processing, which will speed up the process of indexing the website, especially if there are many pages. You can use filters or create separate restrictions for our crawler using the robots.txt file to exclude information pages.
What is the difference between the number of indexed pages and the number of product offers?
The number of indexed pages is the total number of pages of the website that are indexed by the crawler. This number includes all the processed pages of the website – the home page, the pages of the catalogue, as well as, depending on the structure of the website – pages with news, articles and reviews, other information pages (contact information, shipping information, etc.).
Каким требованиям должны соответствовать URL товарных предложений Интернет-магазина?
URL товарных предложений Интернет-магазина должны соответствовать стандарту RFC1738. Данное ограничение связано с техническими требованиями для передачи данных о товарных предложениях в Яндекс.
Возможно ли создать YML для сайта, использующего кириллический домен?
Да, наш сервис индексирует кириллические домены.
