Description

XC SEO Engine is a premium, AI-first SEO plugin for WordPress, developed by XaniaCode. It goes beyond traditional SEO by optimizing your website not only for Google and Bing, but also for AI assistants such as ChatGPT, Claude, Perplexity, and Gemini — the new content discovery frontier.

Frequently Asked Questions

One-time payment. Your license is lifetime with no expiration date. Plugin updates are included for life and delivered directly through the WordPress Plugins screen — no manual download required.
Each license covers one production domain. Development and staging environments on the same root domain are included at no extra cost. For additional production sites, purchase additional licenses.
When another SEO plugin is detected, XC SEO Engine automatically disables its own meta tags, canonical, and Open Graph output to prevent duplication. Schema.org, llms.txt, redirects, and sitemap enhancements stay active. Per-post data can be migrated from those plugins via XC SEO → Import / Export.
Yes. A time-limited version with full features is available. Click "Start Free Trial" on the product page to download it.
llms.txt is a proposed standard — similar to robots.txt — that helps AI assistants (ChatGPT, Claude, Perplexity, Gemini) discover and correctly index your site's content. XC SEO Engine generates and serves /llms.txt, /llms-full.txt, and /.well-known/ai-plugin.json automatically. No extra configuration required.
No. Google's terms prohibit automated scraping. The tracker uses an extensible xcseo_rank_provider filter hook so you supply positions via the bundled Search Console addon, the bundled SerpAPI addon, or any third-party SERP API of your choice.
No. Variant rotation is computed from a date formula on each request — there is no extra database query per page load. Impression counts are stored as a single aggregated daily row per variant, so the database stays small regardless of traffic volume. Bot traffic is filtered from all counts.
Yes. The built-in migrator supports Yoast SEO, Rank Math, and All in One SEO (both legacy postmeta and the modern AIOSEO custom table). Migration is non-destructive — existing XC SEO values are never overwritten. A --dry-run flag is available via WP-CLI.
301 and 302 redirects with exact paths, wildcards (/blog/*), and regex patterns with capture groups ($1–$9). Loop prevention is built in. A redirect log and 404 tracker show which rules fire and which URLs return no match.
Only for license validation and update checks. No user data, no analytics, and no third-party tracking scripts are bundled in the plugin.
No. It is free and bundled with every XC SEO Engine license. Google Search Console itself is also free.
Yes. Google's Search Console API requires OAuth 2.0 authentication, which means you need an OAuth 2.0 client (Client ID + Client Secret) from a Google Cloud project with the Search Console API enabled. The addon settings page includes step-by-step instructions for creating one.
No. It is a rank provider addon designed specifically for XC SEO Engine. If the core plugin is deactivated, the settings page falls back to a standalone location under WordPress Settings, but no rank data can be recorded without the core plugin active.
Google Search Console has roughly a 48-hour reporting lag. The addon pulls approximately 28 days of performance data, ending two days before the current date. Real-time data is not available through the API.
Not in this version. Only URL-prefix properties (e.g. https://example.com/) are supported. Domain properties, which cover all subdomains and HTTP/HTTPS variants, may be added in a future release.
The token is encrypted at rest with AES-256-CBC + HMAC-SHA256, using a key derived from your WordPress salts. If your salts rotate and XCSC_ENC_KEY is not set in wp-config.php, decryption will fail and the addon will prompt you to reconnect. Defining XCSC_ENC_KEY in wp-config.php avoids that scenario.
Yes — each keyword rank lookup is one API call. The Search Console API allows up to 30,000 calls per day per project, which is sufficient for most sites unless you track a very large volume of keywords.
The addon settings page walks you through each step: create a Google Cloud project, enable the Search Console API, create a Web Application OAuth 2.0 client, add the redirect URI shown in the plugin, paste the Client ID and Client Secret, then click Connect to Google.
his addon is built specifically for SerpAPI. For DataForSEO, ScrapingBee, ValueSERP, or other providers, you can use this addon's code as a reference and adapt the API endpoint and response parsing. The xcseo_rank_provider filter pattern is identical for all providers.
Google, Google News, and Bing. Engine selection is available in the addon settings, along with location targeting for 11 preset countries and configurable language (hl) and country (gl) parameters.
