Website SEO on React and Vite: HTML, indexing and page verification

Compare the original answer and the page in the browser

Open the HTML source and find the service name, description, and links. Then compare to a normal page after executing JavaScript. If the source contains only an empty application container, the search depends on additional rendering. For important commercial pages, this is an unnecessary dependency.

Look, how analytics and AI tools indexes sites with JavaScript, and use page verification in Webmaster. Successful opening in your browser does not prove that the text has already entered the search database.

SSR, pre-render and static HTML

SSR generates HTML when making a request to the server. Pre-render creates pages at build time. A static multi-page site can only use JavaScript for the interactive parts. The choice depends on the update frequency and how the data is organized.

For a small service website, static pages with a separate address for each service are often sufficient. For a large dynamic directory, server-side rendering may be necessary. It is not necessary to transfer the entire project to a new platform if the current one allows you to solve the problem.

Checking every URL

• The address opens directly, without first visiting the main page.
• The HTML has a title, useful text, and links.
• Title, description and canonical refer to the current page.
• A non-existent address returns HTTP 404, not the main one with code 200.
• The sitemap lists only the necessary canonical pages.
• Demos and offices receive suitable indexing rules.

The preliminary HTML must match the interface

You cannot give the robot a separate text that the visitor will never see. The initial HTML must represent the same product. Once the application is launched, the content remains accessible and interactive elements are connected on top of a consistent structure.

Test the page without JavaScript, on a slow network, and after it has fully loaded. If the animation hides the cards before the script executes, the useful text may remain invisible when loading fails. It's better to make the content visible by default and enable motion after successful initialization.

Analytics and release

For an application with transitions without fully loading, the counter should receive correct page views. The success of the form is measured after server confirmation, and the click on the external chat separately. In QA, it is useful to exclude test views and not submit real tickets.

Before publishing, save the previous build, check the asset paths and re-traverse the live addresses. Submitting a sitemap helps discovery, but does not guarantee indexing. To check the project there is technical SEO audit; for a new project website development.
