Visit [Verify domain ownership](/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/configure-targets/verify-domain-ownership.md) to learn why domain verification is required. ## The problem Domain verification using a meta tag fails with the error: `Meta tag not found.` ## Troubleshoot the problem Work through the following steps to identify the possible causes and solutions. ### Check the index page source Test if the meta tag is present in the index page source in one of the following ways: * Use the browser: 1. Type the URL to the index page: `https://`, for example: `https://example.com`. 2. Right-click the page and select **View Page Source**. * Use a curl command like this: `curl -i https://`, for example: `curl -i https://example.com`. Analyze the HTML of the index page source, check the following possible causes, and apply the solution: | Cause | Solution | | ---------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------- | | The meta tag is not on the index page. | Review the implementation to add the meta tag before the closing `` tag on the index page. | | The meta tag is on the index page, but not inside the `` tag. | Review the implementation to have the meta tag before the closing `` tag on the index page. | | The meta tag is on the index page inside the `` tag, but it is being injected using JavaScript (for example, a Single-Page Application). | Review the implementation to add the meta tag before the closing `` tag on the index page without using JavaScript. | After following these steps and applying the solutions, you can verify your domain using a meta tag. ## Related articles * [Verify domain ownership](/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/configure-targets/verify-domain-ownership.md) * [Verify domain with meta tag](/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/configure-targets/verify-domain-ownership/verify-with-meta-tag.md) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.snyk.io/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/troubleshooting/domain-verification/troubleshooting-verify-domain-meta-tag.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
