SerpX SEO Inspector for VS Code

Catch basic on-page SEO issues before deployment, right inside Visual Studio Code.

SerpX SEO Inspector checks the source of your active HTML or template file, presents a compact report with an indicative static-check score, and helps spot common metadata and content issues. No account or API key is required.

What it checks

Page <title>: presence and duplicate tags
Meta description and mobile viewport
Canonical URL element
Main <h1> heading count
<img> elements missing an alt attribute
Root <html lang> declaration
Open Graph title, description and image
Explicit noindex notices
JSON-LD detection (presence only, not schema validation)

Get started

Install SerpX SEO Inspector.
Open an HTML file (or a Blade/PHP/Vue template containing HTML markup).
Press Cmd/Ctrl + Shift + P and choose SerpX: Audit Active File.
Review the side-panel summary and fix relevant items in your project.

You can also use SerpX: Copy SEO Audit Report to copy JSON results, or the SerpX SEO item in the status bar.

Important limitations

This is a source-level heuristic audit, not a live site crawler. It does not execute scripts, render templates, fetch remote resources, validate JSON-LD content, check accessibility comprehensively, or assess search engine rankings. Results on layout fragments, server-rendered apps, and component source files may contain warnings that are correctly handled in your site's final rendered HTML. The 0–100 score is an indicative local checklist, not a Google metric.

Privacy

The extension analyzes the active file locally and does not transmit file contents, telemetry, or personal data to SerpX or third parties. Opening the SerpX website is an explicit user-triggered command. There are no background network calls.
