How to Translate HTML Web Files and Optimize Multilingual SEO?

Core Issue Diagnosis

“Conventional translation tools often overlook `<meta>` tags or disrupt HTML nesting structures, leading to loss of SEO value or layout issues after deployment.”

Root Cause Analysis

Synchronization of Metadata and SEO Attributes

In addition to translating the main content, intelligently identify and translate `<title>`, `<meta name='description'>`, and image `alt` attributes. This ensures that multilingual versions maintain equal ranking weight in search engines such as Google.

DOM Structure Integrity Protection

Leverage DOM parsing techniques to interpret HTML as a tree structure rather than plain text. Strictly preserve the closure relationships of tags such as `<div>`, `<span>`, and `<a>`, as well as the `id` and `class` attributes, ensuring seamless inheritance of CSS styles after translation.

Isolation of Code Blocks and Scripts

Automatically identify code within `<script>` and `<style>` tags, designating these as 'non-translatable zones' to prevent JavaScript logic from failing due to translated variable names.
