siteIQ vs SEMrush's Free Plan
SEMrush is a large, paid SEO and marketing suite — keyword research, rank tracking, competitor research and more — with a limited free tier that samples a slice of those features. siteIQ isn't trying to be that whole suite: it's a free, no-signup technical audit tool focused on security, performance, SEO and accessibility for a single site.
| Feature | siteIQ | SEMrush (free plan) |
|---|---|---|
| Signup required | ||
| On-page SEO / technical audit | Limited on free plan | |
| Security header & SSL checks | ||
| Accessibility checks | ||
| Keyword research & rank tracking | ||
| Backlink / domain analysis | Basic | Extensive (paid plans) |
| Competitor research suite | ||
| Core focus | Free technical site audit | Full marketing & SEO suite (paid) |
Which one should you use?
If you need keyword research, rank tracking and competitor analysis, that's SEMrush's core strength — but the full feature set sits behind a paid subscription, with the free plan offering only a limited sample. If what you need right now is a fast, free technical health check — security headers, page speed, on-page SEO, accessibility — siteIQ covers that without an account or a paywall.
Many people use both: siteIQ for a quick, free technical audit, and a paid suite like SEMrush when they need deep keyword and competitor research on top of that.
