Paste your AnswerScan fixes into WordPress
llms.txt
Upload the file to your site root with your host's file manager (public_html/llms.txt), or install the "WP llms.txt" style plugin and paste the content there. Verify at yoursite.com/llms.txt.
robots.txt
If a physical robots.txt exists in your root, edit it with the file manager and apply the AFTER lines from your fix pack. If not, use an SEO plugin (Yoast/Rank Math both have a robots.txt editor under Tools) and paste the AFTER lines there.
JSON-LD
Install WPCode (or any header/footer snippet plugin), add a new Header snippet, paste your schema inside <script type="application/ld+json">…</script>, set it site-wide, activate.
FAQ block
Edit your homepage or FAQ page, add a "Custom HTML" block, paste faq.html. Paste faq-schema.jsonld as a second header snippet the same way as the JSON-LD above.
