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.

External services

ShasTech SEO Synergy can send published or updated URLs to the IndexNow endpoint operated by Microsoft Bing when IndexNow is enabled. The request contains the site’s hostname, the URLs being submitted, the site’s IndexNow key, and the public key-file location. No visitor data is sent.

Service: IndexNow / Microsoft Bing
Endpoint: https://www.bing.com/indexnow
IndexNow terms: https://www.indexnow.org/terms

The verification status tool may make a server-side request to the site’s own homepage and configured virtual verification file. It does not send that test data to ShasTech SEO Synergy or ShasTech-IT.

The Performance SEO tool only runs when an authorized editor clicks the scan button. It makes a server-side request to the selected post’s public URL on the same WordPress site, analyzes up to 2 MB of returned HTML, and stores the latest report in post metadata. It does not send the page or report to ShasTech SEO Synergy, ShasTech-IT, or another external service.

Privacy

The optional 404 logger stores the requested path, a query-free referrer URL when available, hit counts, and first/last-seen timestamps. It does not store visitor IP addresses or user-agent strings. Site administrators can clear the log at any time.

SEO Action Center scope

The Action Center inspects a maximum of 20 recent posts per page. Post type, status and category are WordPress query filters. Local SEO scores, priority levels and script-aware guidance are calculated only for that page and filtered in memory. These are not site-wide counts or language classification. Selecting multiple posts only previews their suggestions; no posts or settings are saved.
