Coretex SEO scans your WordPress content and uses the AI provider you choose to identify SEO and content improvements.
Every recommendation is placed in an approval queue. Nothing changes on your website until you approve it.
Use your own AI provider and API key. There is no Coretex account, licence key or registration required, and the plugin does not connect to Coretex servers.

You Stay in Control
Coretex SEO does not automatically make AI-generated changes to your website.
The AI proposes improvements. You decide what happens next.
Recommendations are placed in a queue where you can:
- Review suggestions
- Edit recommendations
- Approve individual changes
- Reject suggestions
- Bulk approve or reject recommendations
Only approved recommendations are applied to your website.

Built to Be Extended
Coretex SEO includes documented action and filter hooks that allow other plugins and extensions to integrate with the plugin.
Developers can add their own:
- Admin screens
- Scan types
- Features
- Feature flags
- Settings panels
- Audit sections
The complete hook reference is included in HOOKS.txt inside the plugin folder.
An optional commercial Coretex SEO Agency add-on is available for agencies managing SEO for clients.
The core plugin is fully functional without the Agency add-on, and the features listed above do not require it.
External Services
Coretex SEO does not connect to Coretex servers.
Third-party services are contacted only when you configure them and perform an action that requires the service.
AI Providers
AI features require an AI provider that you configure.
When an AI scan is performed, Coretex SEO may send the title, excerpt and relevant post content to the AI provider you selected. Your Site Profile information may also be sent if you have configured one.
No AI request is made until you run a scan or enable a scheduled audit.

Service: https://api.indexnow.org
Nothing is sent unless you manually trigger an IndexNow submission.

DataForSEO
DataForSEO is optional.
If you provide DataForSEO credentials, keyword research can use real search-volume data. The keyword strings being researched and country code are sent to DataForSEO.
Without DataForSEO credentials, Coretex SEO uses AI-generated estimates instead.
Service: https://api.dataforseo.com
Your Website
The SEO audit can request pages from your own website to check links, canonical tags and indexability.
These requests are made directly to your own domain and are not sent through Coretex servers.
