ShasTech SEO Synergy

ShasTech SEO Synergy is a lightweight WordPress SEO plugin designed for news publishers, blogs, and content-heavy websites. The plugin provides editable metadata, canonical URLs, Open Graph and X/Twitter cards, structured data, XML sitemaps, a Google News sitemap, Content Intelligence, local Performance SEO checks, IndexNow submissions, internal-link suggestions, redirects, 404 logging, site verification, and author/publisher signals. Main features

Optional Pro add-on ShasTech SEO Synergy Pro is a separately distributed optional add-on for AI-assisted editorial workflows, scheduled audits, broken-link crawling, redirect recommendations, and read-only Google Search Console/Analytics reporting. The free plugin remains fully functional without Pro. Important notes ShasTech SEO Synergy prevents activation while supported conflicting SEO plugins are active. Deactivate other full SEO plugins before activation to avoid duplicate metadata and schema. Search engines decide whether and how content is indexed or displayed. The plugin improves technical signals but cannot guarantee rankings, Google News inclusion, or Google Discover traffic.
