How to add structured data

Structured data is a standardized format for providing information about a page and classifying the page content. If you're new to structured data, you can learn more about how structured data works.

Here's an overview of how to build, test, and release structured data.

Add the required properties. Based on the format you're using, learn where to insert structured data on the page.
Using a CMS? It may be easier to use a plugin that's integrated into your CMS.
Using JavaScript? Learn how to generate structured data with JavaScript.
Follow the guidelines.
Validate your code using the Rich Results Test and fix any critical errors. Consider also fixing any non-critical issues that may be flagged in the tool, as they can help improve the quality of your structured data (however, this isn't necessary to be eligible for rich results).
Deploy a few pages that include your structured data and use the URL Inspection tool to test how Google sees the page. Be sure that your page is accessible to Google and not blocked by a robots.txt file, the noindex tag, or login requirements. If the page looks okay, you can ask Google to recrawl your URLs.
Note: Allow time for re-crawling and re-indexing. Remember that it may take several days after publishing a page for Google to find and crawl it.
To keep Google informed of future changes, we recommend that you submit a sitemap. You can automate this with the Search Console Sitemap API.

我们之所以制定这些数学求解器内容指南，是为了确保我们的用户能够找到相关的学习资源。如果我们发现内容违反这些政策，将采取适当措施，这可能包括采取人工处置措施并将您的网页从 Google 上的数学求解器功能中移除。

我们不允许将宣传内容伪装成数学求解器，例如由第三方（如联属营销计划）发布的内容。
通过此功能呈现数学求解器时，您将对其准确性和质量负责。在质量审核流程中，如果我们发现一定数量的不准确数据，则根据不准确的程度，可能会从该功能中移除您的求解器，直到问题得到解决为止。适用范围：
- 求解器能够求解的数学题类型的准确性。
- 求解器声明可以求解的数学题的解法准确性。

结构化数据类型定义

要使您的内容能够显示为富媒体搜索结果，您必须为其添加必需属性。您还可以添加建议的属性，以便向结构化数据添加更多信息，进而提供更好的用户体验。

MathSolver

MathSolver 是一款工具，可以为学生、老师和其他人列出求解步骤，从而帮助他们求解数学题。请在网站的首页上使用 MathSolver 结构化数据。

如需了解 MathSolver 的完整定义，请访问 schema.org/MathSolver。

Google 支持的属性如下：

必需的属性
`potentialAction`	`SolveMathAction` 该操作会转到数学表达式的数学解释（例如求解步骤或图表）。 { "@type": "MathSolver", "potentialAction": [{ "@type": "SolveMathAction", "target": "https://mathdomain.com/solve?q={math_expression_string}", "mathExpression-input": "required name=math_expression_string", "eduQuestionType": "Polynomial Equation" }] }
`potentialAction.mathExpression-input`	`Text` Google 发送到您网站的数学表达式（例如：x^2-3x=0）的占位符。然后，您可以“求解”该数学表达式，这可能涉及简化、转换或求解特定变量。此表达式可以采用多种格式（例如：LaTeX、Ascii-Math，或者您可以使用键盘输入的数学表达式）。 `mathExpression-input` 是一个带注解的属性。如需了解详情，请参阅 `Potential Actions` 页面。对于某些问题类型，`math_expression_string` 会指明问题类型和问题类型的参数。以下是一些更复杂的问题类型示例，以便您可以正确预测和解析这些问题。求导 Google 会发送以下两种格式之一的 `math_expression_string`： (`math_expression`)' d/d`variable` `math_expression` Examples: `(x^2+x)'` `d/dx (x^2+x)` `d/dy y^2+y` Integrals Google will send a `math_expression_string` in one of two forms: \int `math_expression` \int_{`from`}^{`to`} `math_expression` 示例： `\int x^2+x` `\int_{0}^{2} x^2+x` 求极限 Google 会发送以下两种格式之一的 `math_expression_string`： \lim `math_expression` \lim_{`variable`\rightarrow`value`} `math_expression` 示例： `\lim_{x\rightarrow0} sin(x)/x` `\lim_{y\rightarrow\infty} sin(y)/y` `\lim sin(x)/x`
