VonSEO

VonSEO isn’t just another SEO plugin; it’s a high-performance publishing engine. Originally forged within the enterprise-grade VonCMS ecosystem, it has been meticulously adapted for WordPress publishers who refuse to compromise on speed, security, and database hygiene.

Stop turning your WordPress dashboard into a heavy SaaS marketing platform. It’s time for Performance-First SEO.

Why Choose VonSEO?

Most SEO plugins become increasingly heavy over time, trading performance for oversized dashboards, telemetry, and marketing layers. VonSEO rejects the bloat.

• Zero-Waste Architecture: No custom database tables. We use native WordPress post_meta and wp_options for maximum speed and compatibility.
• Enterprise Heritage: Built with the same performance DNA as VonCMS.
• Privacy as a Feature: No tracking or telemetry. Editor analysis and Site Audit stay local; optional IndexNow notifications and manual Competitor scans make the outbound requests described below.
• No Paywalls: What you see is what you get. No hidden “Pro” tabs or forced upgrades.

External services and public discovery

Local diagnostics and browser preferences

VonSEO has no built-in telemetry or analytics tracking. Optional 404 logging stores up to 50 requested URLs locally, with hit counts and last-hit times, not visitor IP addresses or user-agent strings. URLs may contain sensitive query parameters. Disabling logging stops new entries but retains saved logs; deleting the plugin removes its local log. The admin settings screen uses sessionStorage only to remember the active settings tab.

Manual validation links

Schema testing buttons open Google or Schema.org with a page URL, falling back to the current editor URL if a permalink is unavailable. These services receive normal browser request information. Inspect the URL before submitting confidential addresses; these are user-initiated links, not background telemetry. Documentation and donation links also open third-party sites with their own privacy policies.

IndexNow (Bing and Yandex)

IndexNow is optional and defaults to off when no enablement has been saved. When enabled, eligible published posts/pages and selected public custom post types are queued for notification after 60 seconds using native WordPress cron; delivery can occur later depending on site traffic or cron configuration. Saved site visibility, password, noindex and content-type eligibility are checked again immediately before notification. Repeated pending updates to the same post share one event. Deactivation and uninstall remove queued events.

The server sends the canonical content URL, site hostname, IndexNow verification key and key-file location to https://www.bing.com/indexnow and https://yandex.com/indexnow. Post bodies, draft text and SEO descriptions are not included. The receiving services can also observe the server’s IP address and normal HTTP request information. Notification does not guarantee indexing.

Manual Competitor scans

When an authorized editor requests a Competitor scan, the WordPress server fetches that editor-supplied URL directly, using the VonSEOWP-Bot/1.0 user agent. The destination website sees the requested URL, server IP address and ordinary HTTP request information; its own terms/privacy policy apply. Current editor content is not sent to that website or an AI service. Successful analysis metrics are cached in a local WordPress transient for 12 hours.

llms.txt

This is a public, curated text endpoint, not an access-control feature or automatic protected-post export. Publish only material intended for public reading. When search-engine visibility is off, or the feature is disabled, both the rewritten endpoint and its query alias return an uncached 404 with noindex/nofollow instead of curated/default text.
