Key points

  • SEO Core AI speeds up page-level audits, keyword analysis, and competitor comparisons inside ChatGPT.
  • Its results are recommendations generated from page data, not direct search engine ranking signals.
  • Always verify AI suggestions with crawl data, Search Console, and analytics before acting on them.
  • Avoid over-optimising titles or copy just to satisfy the tool; write naturally for users first.
  • The plugin may be renamed, reworked, or removed as ChatGPT plugin support evolves.

How it works

SEO Core AI is a ChatGPT plugin that takes a URL and an optional keyword, then uses AI to analyse the page's SEO and content. It returns recommendations covering on-page elements, content optimisation, and competitor comparisons. The plugin exposes a core analysis command that processes the page data and generates advice.

The tool is designed as a fast triage layer, not a replacement for dedicated tools like ahrefs or manual review. For example, it can suggest improvements to title tags or headings, but those suggestions should be checked against actual crawl data and Search Console. It is most useful for quick audits and idea generation, especially when combined with chatgpt seo prompts to refine the output.

SEO advice from any AI tool can become outdated quickly because Google's systems and spam policies evolve; always validate recommendations against current Search Central guidance.

How to use it

  1. Open ChatGPT with plugin support enabled (GPT-4 with plugins).
  2. Install SEO Core AI from the plugin store.
  3. Enter a command such as 'Analyse this URL for SEO' followed by the target URL and an optional keyword.
  4. Review the generated recommendations for on-page issues, content gaps, and competitor insights.
  5. Cross-check the suggestions with your own data from Search Console, analytics, and a tool like ahrefs keyword generator for keyword validation.
  6. Apply only the changes that align with the page's intent, brand voice, and business priorities.
