ABDS SEO

The free plugin is fully functional on its own; the paid tiers add capabilities, they do not cripple the free ones.

External services

This free plugin contacts two third-party services, each only when you choose to use the feature that needs it: the ABDS License Server (when you activate a license) and IndexNow (when you switch on IndexNow submission, which is off by default):

• ABDS License Server (https://license.abds-seo.com) — contacted in two cases. (1) Opening the plugin’s Plans screen (Settings before 0.10.0) fetches the current subscription prices, an anonymous public request that sends no license key, site URL, or any other site-identifying data; the result is cached, so this isn’t repeated on every visit, and a failed request just falls back to the plugin’s built-in prices. (2) Activating a license key (to validate it), or the ABDS SEO Pro add-on checking your license and fetching its own updates — these send your license key, your site URL, and a random per-install identifier (not derived from any WordPress secret). A free install that never opens Plans and never enters a license key makes no contact at all. Governed by the ABDS Terms of Service (https://abds-seo.com/en/terms) and Privacy Policy (https://abds-seo.com/en/privacy).
• IndexNow (https://api.indexnow.org/indexnow) — a protocol that tells participating search engines a page has changed. It is contacted only if you switch on IndexNow in SEO → Indexing yourself: it is off by default and is never switched on by an update. Nothing is sent from a local or staging copy of a site that is not publicly reachable. When you publish or update a published post or page, the plugin sends one request containing exactly: the address of that page (which includes your site’s host name), the IndexNow key stored in this plugin, and the address of the key file at your site root (the protocol requires that file to be public so search engines can verify the key). A request that times out or is rate-limited is retried once with the same content. Nothing else is sent: no visitor data, no personal data, no license information. IndexNow’s Terms of Use are at https://www.indexnow.org/terms. The service does not publish a separate privacy policy; the privacy section of those terms says the protocol’s sponsors (Microsoft Corporation, Yandex N.V. and Seznam.cz) log incoming requests, including the sending server’s IP address, and that these logs are kept indefinitely as administrative and research material. Documentation: https://www.indexnow.org/documentation.

Nothing else in this free plugin makes third-party network calls. The technical audit, rule-based content analysis, migration, and snippet preview all run locally, and the scanner only fetches your own site’s pages (a same-site loopback request) to inspect their markup.

The optional paid integrations — AI assistants (OpenAI-compatible, Anthropic, Google Gemini), SERP/competitor analysis, DataForSEO keyword and backlink data, Google Search Console, and the agency multi-site cabinet — are not part of this free plugin . They live in the separate ABDS SEO Pro add-on and connect to their own services only after you enable each one there with your own credentials; those services are documented with that add-on.

Source code

The JavaScript and CSS in the build/ folder are compiled with @wordpress/scripts (webpack). The uncompiled, human-readable sources are included in this package under /src ( admin.js , index.js , search-appearance.js , indexing.js , sidebar.js , snippet-width.js , style.css ). To rebuild them, run npm install and then npm run build in the plugin folder.

Third-Party Libraries

Because this plugin is distributed as “GPLv2 or later”, combining it with a GPLv3 component is compatible: the combined work is distributed under GPLv3.
