Google 有时可能会采用其他方法从网页中提取数据。如果您希望明确告知 Google 不要使用网页上的内容生成摘要,请向该 HTML 元素添加 data-nosnippet 属性。
将数据上传到 Google Merchant Center
虽然将商品数据上传到 Google Merchant Center 并不是让商品显示在 Google 搜索结果中的必要条件,但这样做有助于 Google 了解您的商品。对于某些 Google 平台(例如“Google 购物”标签页中的商品详情),参与 Google Merchant Center 是一项强制性要求。
如果 Google 合并您的网站和 Google Merchant Center Feed 中的数据,则可能会因延迟而导致数据不一致问题。例如,如果某件商品售罄,您的网站通常会立即将其标记为无法购买,但 Google Merchant Center 可能过一段时间才会更新,尤其是在您使用 Feed 时。
为避免价格和库存状况数据发生这种潜在冲突(这是导致同步问题的一种常见原因),请在发现此类差异时,告知 Google Merchant Center 根据网站内容自动更新您的商品数据副本。

To take advantage of these benefits, Google recommends that you do the following:\n\n- **Include structured data in your site's product pages** . Learn more about the benefits of [adding structured data to your web pages](#add-structured-data).\n- **Tell Google directly which products you want to show on Google** by uploading a feed to [Google Merchant Center](https://support.google.com/merchants/answer/188924). Google Merchant Center is a Google service that has a deeper understanding of commerce data. Learn more about the [benefits of Google Merchant Center](#upload-product-data).\n\nAdd product structured data to web pages\n----------------------------------------\n\n\nWhere feasible, add structured data to your product pages. While structured data isn't\nrequired to appear in Google Search results, it can help Google understand your page better\nand display it as a rich result. For example:\n\n- Structured data increases eligibility for [Product rich results](/search/docs/appearance/structured-data/product).\n- Structured data can improve the accuracy of Google's understanding of content such as price, discount, and shipping costs on a page (this can also help the accuracy of Google Merchant Center verification of product feeds against your site).\n\n\nReady to start implementing? Check out\n[Include structured data relevant to ecommerce](/search/docs/specialty/ecommerce/include-structured-data-relevant-to-ecommerce)\nfor more information.\n\n\nGoogle may at times use other approaches to extract data from pages. If you want to explicitly\ntell Google not to use content on a page to form a snippet, add a\n[`data-nosnippet` attribute](/search/docs/crawling-indexing/robots-meta-tag#data-nosnippet-attr)\nto that HTML element.\n\nUpload data to Google Merchant Center\n-------------------------------------\n\n\nWhile uploading product data to Google Merchant Center isn't mandatory to appear in Google\nsearch results, it can enhance Google's understanding of your products. Participation in Google\nMerchant Center is mandatory for some Google surfaces, such as listings in the\nGoogle Shopping tab.\n| **What is Product Data?** Product data describes various attributes of products, such as its title, description, color, pricing, and availability.\n\n\nFor smaller sites that are updated less frequently, you can use an\n[automated feed to build your product data](https://support.google.com/merchants/answer/7538732)\nfrom crawled web content (structured data can help improve the accuracy of data extraction).\nThis approach can also be useful to get started with less effort.\n\n\nFor larger sites or sites with frequently changing content, periodically\n[upload new data feed files](https://support.google.com/merchants/answer/188477)\nto Google Merchant Center (or for immediate updates use the\n[Content API](/shopping-content/guides/quickstart)).\nThis gives you greater control over your data in Google. Benefits of uploading feed files include:\n\n- **Increase confidence Google knows all of your products**. Web crawling is not guaranteed to find all products on your site.\n- **Gain greater control over the timing of updates**. Google does not guarantee how long it takes before changes on your site will be processed through crawling. Feeds can be used for weekly, daily, or even hourly updates, at your time of choice. The Content API allows immediate content updates, which is particularly useful for stock level updates.\n- **Share data that's not present on your website**. You may decide some information is not appropriate to include on your web site, such as physical store level inventory data. Feeds and the Content API let you share this data with Google without it being present on your website.\n\n\nLearn more about how to\n[Sign up for Google Merchant Center](https://support.google.com/merchants/answer/188924).\n\nHow Google uses structured data and Google Merchant Center data\n---------------------------------------------------------------\n\n\nThe following are examples of how Google uses structured data embedded in web pages and Google Merchant Center data\nfor different experiences. Note that experiences may vary by country, device, and other\nfactors.\n\n| Experience | Structured Data | Google Merchant Center |\n|----------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------|\n| **Product rich results in Google Search** | Google Search uses [Product structured data](/search/docs/appearance/structured-data/product) to display product rich results. | Google Search may use Google Merchant Center data to display product rich results. |\n| **Google Images results with product annotations** | Google Images uses [Product structured data](/search/docs/appearance/structured-data/product) to display product annotations on images. | Google Images uses images listed in Google Merchant Center. |\n| **Google Shopping tab** | Adding structured data can help Google Merchant Center in some cases (for example, during data verification). | Participation in Google Merchant Center is required to appear in the Google Shopping tab. |\n| **Google Lens image search results** | Google Lens uses [image structured data properties](/search/docs/appearance/structured-data/sd-policies#images) where available. | Google Images uses images listed in Google Merchant Center. |\n\nResolving update delay issues\n-----------------------------\n\n\nWhen Google combines data from your website and Google Merchant Center feeds, it can lead to\ndata inconsistency issues due to lag. For example, if a product sells out, your website would\ntypically immediately mark it as unavailable for purchase, but Google Merchant\nCenter may not be updated until some time later, especially if you're using feeds.\n\n\nTo avoid this potential conflict in pricing and stock availability data (a common cause of\nsynchronization issues), tell Google Merchant Center\n[to automatically update its copy of your product data](https://support.google.com/merchants/answer/3246284)\nbased on the website contents, when such a discrepancy is noticed.\n\n\nTo learn more about how Googlebot and Google Merchant Center work together, see\n[How to get your products into Search](https://www.youtube.com/watch?v=UQtdv_hoGuM)\nfrom the Search Central Lightning talk series."]]
