How to Validate hCard Microformat with Yandex Validator

Validating hCard microformat requires using the Yandex Structured Data Validator to check your contact markup for errors. You paste your URL or code into the tool to confirm that the vcard root and mandatory elements like fn, org, and adr are present. This ensures Yandex Business can correctly extract your organization’s physical address and phone number for search results in supported regions like Russia or Kazakhstan.

What is the Yandex Structured Data Validator?

The Yandex Structured Data Validator is a specialized tool within the Yandex Webmaster panel designed to verify how the search engine parses microformats, Schema.org, and other semantic markups. For hCard, it specifically looks for the vcard class and its associated properties. Using this tool is a key step before submitting your site for indexing, as it prevents data extraction failures that could keep your business from appearing on maps or in local search snippets.

When you use the validator, you can either provide a direct link to a live page or paste a block of HTML code. The tool analyzes the hierarchy of your tags and highlights any missing mandatory fields or incorrect nesting. This immediate feedback allows developers to fix issues in the code before the Yandex spider visits the site.

Which hCard properties are mandatory for Yandex?

Yandex has a strict set of requirements for accepting organization data into its business directory. If these specific properties are missing or formatted incorrectly, the validator will flag them as errors. The engine requires a clear identification of the business entity and a physical location that users can visit.

• vcard: The root element that must wrap all other contact information.
• fn and org: The full name and organization name. Yandex requires these to have the same value.
• adr: The physical address container which must include detailed location data.
• locality: The city or town where the business is located.
• tel: A valid telephone number including the city and country code.

The most common mistake we see is separating the fn and org classes. Yandex prefers these to be on the same element, such as a single span tag. This simple adjustment often resolves validation warnings immediately.

Why does the validator show errors for nested properties?

Markup processing rules for hCard are quite specific about how elements should be structured. A frequent issue occurs when developers nest properties that the standard does not explicitly allow. For example, placing a telephone number (tel) inside an address block (adr) can lead to incorrect processing. The validator will often fail to recognize the phone number if it is buried inside the address hierarchy.

The rules state that certain properties are allowed to be nested within the adr class to provide a detailed location. These include the country-name, region, locality, street-address, extended-address, and postal-code. Any other data, such as a logo or an email address, should remain outside the adr block but still within the vcard root. Following these structural boundaries is a solid way to ensure your data is read correctly.

How Alien Road applies hCard validation

When Alien Road manages a project for a client targeting the CIS market, we follow a detailed verification process. We start by auditing the existing contact page to ensure the physical address matches the one intended for Yandex Business. Since Yandex only processes these cards for Russia, Ukraine, Belarus, and Kazakhstan, we first confirm the regional relevance of the business.

In a typical engagement, for example, for a retail chain in Almaty, we implement separate vcard blocks for each branch that has a unique phone number or specific address. We use the abbr tag with the title attribute for phone numbers to ensure the machine-readable format is perfect while keeping the visible text user-friendly. Once the code is live, we run it through the Yandex Structured Data Validator and document the ‘valid’ status before moving to the next phase of the SEO strategy.

Can you validate multiple branches on one page?

Yes, it is possible to validate multiple locations on a single page, but you must follow specific rules for how they are grouped. If the branches share the same name and contact details, such as a single call center number, you can list multiple addresses within one card. However, if the branches have different names, unique phone numbers, or different email addresses, you must create a separate vcard container for every single location.

Yandex specifically looks for actual addresses that people can visit. Validating a legal or registered office address that does not serve customers is often a waste of time, as the goal of this markup is to help users find physical business locations. When using the validator, ensure that each vcard is distinct and contains all the mandatory properties independently.

Understanding the adr element breakdown

The address component is where most technical errors happen. To pass validation, the adr element must be broken down into its constituent parts. Providing a single string of text as an address is usually not enough for the engine to categorize the location accurately.

• country-name: The name of the country (e.g., Kazakhstan).
• region: The state or province, which is required if the locality name is not unique.
• locality: The city or settlement name.
• street-address: The specific building number and street name.
• extended-address: Additional details like the office number, floor, or business center name.
• postal-code: The standard mailing code for the area.

Remember that Yandex Business is the ultimate destination for this data. If your locality is not clearly defined within the adr tag, the system might fail to place your business on the map correctly, even if the rest of the markup is technically valid.

How to test your contact data for errors?

Testing involves a simple workflow within the Yandex Webmaster interface. First, navigate to the ‘Tools’ section and select ‘Structured data validator’. You will see a text area and a URL input field. If you are still in the development phase, copy your HTML snippet and paste it into the text area. If your site is already live, enter the URL of your contact page.

After clicking the check button, the tool will generate a report. A successful validation will show a green checkmark or a message indicating that the hCard was found with no errors. If there are issues, the tool provides a list of specific errors, such as ‘Missing mandatory field: org’ or ‘Incorrect nesting of tel’. You should address these errors one by one until the report is clear.

Where to start this week

Begin by auditing your main contact page to see if any hCard markup currently exists. Use the Yandex Structured Data Validator to check the current status of your page. If the validator finds no markup or identifies errors, follow these steps to resolve them:

• Wrap your contact information in a div with the class ‘vcard’.
• Ensure the organization name is marked with both ‘fn’ and ‘org’ classes.
• Break your address into the specific sub-properties like ‘locality’ and ‘street-address’.
• Check that your phone number is in the international format within an ‘abbr’ tag title attribute.
• Re-run the validator to confirm all errors are gone.

Once the validation is successful, you can be confident that Yandex will correctly index your business location. If you prefer not to use markup, you can also submit your data through the ‘Site geography’ section in the Yandex Webmaster console, which serves as a reliable alternative for getting your details into Yandex Business.
