I tested ChatGPT against SEO-specific AI writers on the same keyword. The results surprised me.
The Test
Same keyword: "email marketing tips for small business." Same rough length. Two different AI tools.
ChatGPT Results
- SEO Score: 38/100
- Keyword not in H2 headings
- No meta description
- Generic intro full of "in today's digital landscape"
- 7+ AI fluff phrases detected
SEO-Focused AI Results
- SEO Score: 82/100
- Keyword in title, H2, first paragraph
- Auto-generated meta tags
- Real statistics with named sources
- Human tone — reads like a marketer wrote it
The Real Difference
ChatGPT was built to be a general-purpose AI. It writes anything — poems, code, emails. But it was never designed to get your content found on Google.
SEO-specific AI tools add what ChatGPT doesn't: keyword strategy, EEAT signals, heading hierarchy optimization, meta tags, and real-time scoring.
The Verdict
Use ChatGPT if you need an all-purpose AI assistant. Use an SEO-specific AI writer if you're a small business that needs blog content that actually brings customers through Google.
I built SEO Spark to solve this exact problem — AI blog posts that rank on Google. 3 free articles, no credit card.
