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.

URL Viewer for Umbraco (16, 17, 18): a backoffice tool in the "SEO Audit" section to fetch any URL as Googlebot/Bingbot (or a browser), follow the full redirect chain, view headers and HTML source, and run a static analysis — on-page SEO, Open Graph/Twitter, technical SEO, content and accessibility metrics, spam/hidden-CSS/JavaScript detection and cloaking — with a composite SEO score. Also exposes an authenticated API to fetch a URL and return the analysis as JSON. Server-side and SSRF-safe. Built on the framework-agnostic T4VN.Seo.Core engine. (For the site-wide crawler, install uTPro.Feature.SEOAudit.)

Crawls every Content & Media URL (plus sitemap.xml), checks for broken links/images/resources, and audits each page for SEO, Open Graph/Twitter, technical SEO, content quality, a static accessibility subset and carbon emissions — with a composite SEO score, a run health score, grouped issues with priority, orphaned/duplicate detection, incremental scans and CSV export, all in a dedicated backoffice section. Runs as a recurring background job (auto-discovered by uTPro Job Monitor). Built on the framework-agnostic T4VN.Seo.Core engine.
