Я обнаружил, что когда я открыл https://huynhsamha.github.io/crypto/algorithm/sha256,, я фактически получил 404 как ответ .Я думаю, что ваш обходной путь для размещения SPA на GitHub с использованием 404.html является проблемой здесь.В то время как мы, люди, видим, что ваше приложение корректно отображается в нашем браузере, googlebot все равно, просто посмотрите на код ответа и убедитесь, что оно получило 404.Вам понадобится другой обходной путь, который не требует использования 404.html в качестве точки входа в ваше приложение напрямую.
Попробуйте выполнить этот обходной путь с помощью rafrex , вместо этого он перенаправляет браузерна index.html с использованием 404.html, сохраняя при этом исходный маршрут, он утверждает, что googlebot зарегистрировал это как 301 вместо 404, для вашего случая, что означает добавление этих изменений ниже на ваш сайт, обратите внимание наскрипт под <!-- ------Single Page Apps GitHub Pages Workaround------ -->:

// If you're creating a Project Pages site and NOT using a custom domain,

// This way the code will only replace the route part of the path, and not

// https://username.github.io/repo-name/one/two?a=b&c=d#qwe becomes
// https://username.github.io/repo-name/?p=/one/two&q=a=b~and~c=d#qwe

It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.
