WooCommerce

WooCommerce runs on WordPress, so you have full control of the site root; keep the shop-specific rules WooCommerce needs.

1.robots.txt: upload the generated robots.txt to the WordPress root (next to wp-config.php) via FTP or your hosting File Manager, or paste it into Yoast SEO > Tools > File editor, or Rank Math > General settings > Edit robots.txt. Keep the Disallow rules for /cart/, /checkout/ and /my-account/ and do not block /wp-content/uploads/ (product images). A physical file replaces the virtual robots.txt generated by WordPress.
2.llms.txt: upload llms.txt to the same root folder so it is served at /llms.txt. Recent versions of some SEO plugins (e.g. Yoast) can generate an llms.txt automatically: if you upload your own, disable that feature to avoid two conflicting versions.
3.Structured data: WooCommerce and your SEO plugin already output Product and WebSite markup. Add only the missing blocks from json-ld.html (e.g. Organization) site-wide with a plugin like WPCode (Insert Headers and Footers) in the <head>, without duplicating the Product schema.
4.Meta: update the homepage and shop page SEO title and meta description from Yoast or Rank Math using the texts in meta-suggestions.html, then purge any caching plugin.
5.Re-scan the domain on AIVIS to confirm the corresponding checks now pass.

Download the bundle from your AIVIS report first, then re-scan the site to check the score went up.
