I spent last weekend doing something dumb: I ran a full technical SEO audit on every SEO tool listed on Product Hunt.
The irony? Most SEO tools have terrible SEO on their own websites.
The Methodology
I used a free audit tool to check each site against 50+ ranking factors: meta tags, structured data, Core Web Vitals, mobile optimization, content structure, internal linking, and more.
Each site gets a score out of 100. Here are the results.
The Scores
| Tool | Score | Biggest Issue |
|---|---|---|
| AuditFlow | 96/100 | Minor: missing hreflang tags |
| Seodity | 82/100 | Slow page load, missing schema |
| Keupera | 79/100 | Thin meta descriptions |
| SEOLint | 37/100 | Missing structured data, broken links |
| Skayle | 37/100 | No meta descriptions, slow TTFB |
Yes, you read that right. Two SEO tools scored 37 out of 100 on their own websites.
The Irony Factor
If an SEO tool cannot optimize its own website, what does that tell you about its recommendations? SEOLint literally checks other sites for SEO issues while having broken links and missing structured data on seolint.com.
Skayle has no meta descriptions. On their homepage. An SEO tool. With no meta descriptions.
What I Learned
1. Most SEO tools focus on features, not fundamentals. They build dashboards and reports while neglecting their own site structure.
2. Score correlates with product quality. The tools that scored highest also had the best UX and most useful features.
3. Structured data is the most commonly missed factor. Even tools scoring 80+ often lack proper Schema.org markup.
I Also Audited the Top Dev Tools
Since I was on a roll, I audited some of the hottest dev tools too:
| Tool | Score |
|---|---|
| bolt.new | 83/100 |
| lovable.dev | 82/100 |
| v0.dev | 80/100 |
| cursor.com | 78/100 |
| replit.com | 68/100 |
Even the best dev tools have room to improve. Replit in particular has significant SEO gaps — thin meta descriptions and missing structured data are leaving organic traffic on the table.
How to Check Your Own Site
The tool I used for this audit is AuditFlow — it is completely free, no signup required. Just enter your URL and get a full technical SEO breakdown in about 30 seconds.
I am genuinely curious what your sites score. Drop your URL in the comments and I will run the audit for you.
What is the most ironic case of a tool not following its own advice that you have seen?
