T4VN.Seo.Core

Framework-agnostic SEO / page-audit engine. Fetches a URL as a chosen user agent (with a DNS-based SSRF guard), follows the redirect chain, and runs a full static analysis — on-page SEO, Open Graph/Twitter, technical SEO, content metrics, a static accessibility subset, spam/hidden-CSS and JavaScript detection, cloaking — plus a composite Lighthouse-style SEO score.

No Umbraco or ASP.NET Core hosting dependency; usable from any .NET app (net8.0 / net9.0 / net10.0).

Usage

services.AddT4VNSeoCore(options =>
{
    options.AllowInternalHosts = false;       // SSRF guard on (recommended)
    options.AllowInvalidCertificates = false; // validate TLS (recommended)
});

Then inject IUrlViewerService and call FetchUrlAsync. The response includes the redirect chain, headers, HTML, analysis (ContentAnalysis / PageAudit) and the computed SeoScore.

The scoring rubric lives in SeoScorer — the single source of truth used by every consumer.
