### Add my Claude AI key to wp-config.php

By adding this code below:

`define( 'SEOPRESS_CLAUDE_KEY', 'XXXXXXX' );`

You will store your Claude API key in your **wp-config.php** file instead of your database. This is more efficient on a multisite network for example but also more secured.

Now you have linked your Claude AI account with your WordPress site, you can use AI to:

- [generate SEO metadata](https://www.seopress.org/support/guides/generate-your-seo-metadata-with-openai/#generate-your-title-and-meta-description-with-ai)
