Google, Microsoft, Yahoo!, and Yandex have collaborated to create a project—Schema.org—to streamline and standardize structured data markup on websites. This allows crawlers to better interpret page content, which in turn translates into more effective search results. What markup does Google accept, and when should we use it?
What is Google structured data?
Structured data is encoded using special HTML tags— schema markup —interpreted by search engines. Google Schema tags added to the code allow users to receive information about products, events, or reviews. Structured data is used to create information visible to the user under search results, such as product prices, ratings, and star ratings.
Google Structured Data and SEO
Google's structured data doesn't directly impact a page's search engine ranking, but its presence indirectly, by providing context to search engine crawlers, allows for better SEO . So how can you best leverage Schema? SEO focuses not only on a page's position in search results but also on CTR, which is the ratio of clicks to link views.
Implementing Google Schema markup allows you to enrich a page's search results, which in turn can increase the click-through rate for links. This means that using structured data often translates into increased organic traffic to a page, thus impacting SEO.

Schema.org Formats
Google structured data can be implemented on a website via:
- microdata – additional values in HTML tags;
- RDFa – HTML5 extensions appearing in sections and ;
- JSON-LD – scripts appearing in the section , independent of the content of the page.
The preferred format remains JSON-LD, which is implemented on a website using a script. You can create your own, following the schema.org documentation, or use professional generators or SEO plugins available online.
Popular Google Schema markup
The structured data set tested in search results consists of nearly 800 tags, but the list of data types supported by Google Search only includes a few dozen. The most popular are:
- Breadcrumbs
- Product
- Review
- Film
- CreativeWork
- LocalBusiness
- FAQ
- Jobs
- Pattern
- Events
To discover the potential of each of these tags and verify whether we can use Google structured data on our own website, it is worth familiarizing yourself with their detailed specifications.
Features of selected Schema SEO tags
Breadcrumbs are used for internal linking and help users navigate a website . In practice, they are a small text path, usually placed at the top of the page, indicating the user's current location on the page.
Schema Jobs describes job postings, including the job title, employment type, and salary. Schema Events works similarly , providing information about various events, including their name, location, and date.
Google Schemas that affect users
Product tags are special search result tags that display information such as currency, price, name, and product description. These elements highlight the value and special features of an offer, encouraging users to click on the link. Schema Review, on the other hand , refers to user reviews, which can be displayed in the results using graphical star ratings or average ratings, which positively influence user response.
Schema Recipe , used in the culinary industry, is also proving to be an indispensable markup . It allows search results to display not only attractive images but also important information such as cooking time and nutritional values.
Most commonly used structured data tags
The popular Schema markup for videos on a website can be found almost everywhere. These elements are displayed in search engines as thumbnails, encouraging viewers to watch the clip and click the link.
An equally frequently used schema is CreativeWork , which is used to provide a detailed description of a work, such as music, paintings, or books, by adding information about the title and author, as well as displaying reviews. Similarly, the LocalBusiness schema is used to provide additional data about a local business , such as its address, opening hours, or reviews.
FAQ , on the other hand, refers to questions and answers displayed directly on the search results page.
Which tags are worth using on your website?
Despite the popularity of a particular Google Schema, its use isn't always effective for a given website . When choosing the best tag, consider several factors: the type of content published on the website, the profile and needs of the target audience, and the specifics of the chosen offer or product. To highlight the most important company information, use the LocalBusiness tag , while to highlight user reviews, use the Review tag.
There's no single rule for using schema.org markup. Testing different combinations can be a good way to see how specific elements impact a link's attractiveness.
Schema.org – Validity Test
Each generated or self-written script should be verified before implementation to ensure correct Schema.org markup. A test that analyzes markup for correctness and visibility after implementation has been provided by Google. This tool highlights any errors and identifies structured data on the page.
The Rich Results Test can be run multiple times, at any time convenient for the user. To do this, simply visit the tool's website and enter the URL of the page you want to test. After a detailed analysis, the system provides complete results regarding the validity of the Schema.org script. The test allows you to verify that the data was entered correctly and that Google is interpreting it correctly.
How to effectively manage structured data?
Google provides a practical tool to help check for any errors that may have crept into the entered structured data – the Rich Results Test . Analyzing the correctness of the implemented Schema.org markup is the most important step, allowing for a quick response and implementation of necessary changes before the page is live.
To achieve the desired results and maintain a high search engine ranking , it's worth meticulously preparing your schema. SEO specialists and webmasters utilize advanced tools that streamline the process of creating and implementing structured data.
What tools are best for creating schema markup?
Essential structured data tools that every beginner and expert should use include:
- Google's Structured Data Markup Helper, a tool for marking elements on a page and generating the appropriate code,
- JSON-LD Generator, which facilitates the creation of code based on shared data,
- structured data tester – Google tool to verify their correctness,
- schema.org markup validator, checking whether the encoding of structured data complies with Schema.org standards,
- Google's AMP testing tool, a tool verifying the correctness of data implementation.
Creating and implementing Google Schema markup using the products mentioned above will become much simpler and faster, and at the same time extremely effective.
How to use Google Schema effectively?
In order to maximize the performance of Google tags, it is necessary to properly prepare the script and implement it properly on the website.
Google's structured data tester will be helpful in this regard . This will allow us to see the proposed changes identified by the test. The schema must be fully valid and compatible with the search engine; otherwise, it will not function effectively.
Structured Data FAQs
Structured data is special code (most often implemented in JSON-LD format) placed within a section of a website's source code. It acts as a universal "translator" for search engine robots (e.g., Googlebot)—it helps the algorithms precisely understand the context and meaning of elements on a page, rather than simply reading them as a simple string of characters.
Adding structured data alone isn't a direct ranking factor, but it has a powerful impact on user behavior. It allows for the display of rich results (Rich Snippets) in Google. This allows your site to stand out visually in search results (e.g., with stars, prices, or dates), which directly:
- Increases click-through rate (CTR).
- It attracts more decisive, better-informed users to the site.
- Helps robots index your website faster and more accurately.
In the e-commerce industry, omitting structured data represents a significant loss of image and sales. The following are absolutely essential:
- Product – specifies the parameters of the item (name, model, brand).
- Offer – provides the current price, currency and information whether the product is in stock.
- AggregateRating or Review – is responsible for generating yellow stars in the search engine with customer ratings and opinions that strongly build trust.
Apart from e-commerce, it is worth using dedicated tags for other types of business:
- LocalBusiness – Ideal for local service businesses, it provides robots with precise addresses, phone numbers, opening hours, and geographic coordinates.
- Article / NewsArticle – for blogs and news portals. Provides the author, publication date, and headline, which increases the chances of the article appearing in Google Discover, among other things.
- BreadcrumbList – A universal breadcrumb navigation marker that converts long, complicated URLs in search results into human-readable categories.
- FAQPage – allows you to display a question and answer section directly below your link in Google (taking up more space on the user's screen).
Google's official, free tool, Rich Results Test, is used to verify code validity. Simply paste the page's URL or a direct code snippet into the tool to see if the system is reading the data correctly and if it contains any critical errors. You can also monitor the comprehensive implementation status of all markup across your entire site in the Google Search Console.
