SEO Audit

Overview

The SEO Audit tool scans your pre-rendered pages and checks them for common SEO issues. Because RndrKit already renders your pages with a headless browser, the audit examines the same HTML that search engines see -- giving you an accurate picture of your SEO health.

Running an Audit

Go to your domain's detail page and click the SEO Audit tab.
Choose which pages to audit:
- All pages -- Audit every page in your sitemap
- Specific URL -- Audit a single page by entering its path
Click Run Audit.

The audit runs against your pre-rendered HTML, not your SPA source code. This means it checks exactly what search engines will see.

Understanding Audit Results

Results are categorized by severity:

Errors -- Critical issues that likely prevent proper indexing. Fix these first.
Warnings -- Issues that may reduce your SEO effectiveness. Address when possible.
Passed -- Checks that your page passed successfully.

Each issue includes:

The affected page URL
A description of the problem
The specific element or tag involved
A recommendation for how to fix it

Fixing Common Issues

Missing or Duplicate Titles

If you are using React Helmet or a similar library, make sure each route sets a unique title:

<Helmet>
  <title>About Us | Your Company</title>
</Helmet>

For Lovable sites, check that each page's title is configured in the page settings.

Missing Meta Descriptions

Add a meta description for every page:

<Helmet>
  <meta name="description" content="A clear, compelling description of this page's content in under 160 characters." />
</Helmet>

Missing Open Graph Tags

Add Open Graph tags for proper social media previews:

<Helmet>
  <meta property="og:title" content="Page Title" />
  <meta property="og:description" content="Page description" />
  <meta property="og:image" content="https://example.com/image.jpg" />
  <meta property="og:url" content="https://www.example.com/page" />
</Helmet>

Missing Structured Data

Add JSON-LD structured data for rich results in search:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Your Company",
  "url": "https://www.example.com",
  "logo": "https://www.example.com/logo.png"
}
</script>

Re-running Audits

After fixing issues in your application, you should:

Purge the cache for the affected pages so RndrKit renders the updated HTML.
Re-run the SEO audit to verify the fixes.
