FRUITA, Colo., Oct. 22, 2026 – M. Curtis McCoy, a website developer and SEO and AEO strategist, today launched Website Analyzer: SEO & AEO, a ChatGPT SEO plugin that grades a business website from A+ to F and lists what to fix first. The plugin is published in the ChatGPT Plugin Directory.
The ChatGPT SEO plugin shows how search engines and AI assistants see a website. A business owner gives it a website address and asks ChatGPT whether search engines and AI can find and recommend the site. In about a minute, the plugin loads the homepage and key pages and reads robots.txt, sitemaps and AI crawler rules. It also checks the domain, hosting, email and security setup and runs Google PageSpeed Insights on mobile.
What the ChatGPT SEO plugin scores
The plugin returns a letter grade from A+ to F, a score out of 100 and six category scores:
- Leads and conversion: can a ready buyer find a phone number, a clear next step and proof to trust the business?
- Search visibility: can Google find and understand the pages?
- Speed and mobile: how the site performs on a phone.
- AI search readiness: whether AI crawlers are allowed in robots.txt.
- Security and trust: the domain, hosting, email and security setup.
- Accessibility: whether every visitor can use the site.
Each result lists the top issues, why each one matters and how to fix it. A link opens the full report on MCurtisMcCoy.com, where the owner enters an email address to see every issue and every fix.
What AEO means for a website owner
AEO, or answer engine optimization, is the work of making a website easy for AI assistants to read, trust and recommend. SEO still decides how a site ranks on Google. AEO decides whether ChatGPT and other assistants can read the site and name the business when a buyer asks who to hire. The two overlap, but a site can do well at one and fail at the other.
The plugin scores both. Its AI search readiness score starts with the basics, such as whether robots.txt lets AI crawlers in. Read more in the guide to what AEO is and the explainer on the difference between AEO and SEO.
Who the plugin is for
The ChatGPT SEO plugin is written for people who run a business and rely on someone else to run the website. That includes contractors, custom home builders, clinics, law firms, real estate professionals and home services companies. The results are written in plain English. An owner can hand them to a web developer, who can act on them.
