The Verdict
Rank Math's free tier is the best WordPress SEO plugin available. But for auditing non-WordPress sites, running comprehensive technical checks, and optimizing for AI search — SerpNap fills the gaps. Best combo: Rank Math (free) for WordPress on-page SEO + SerpNap for technical auditing and AI search optimization.
Frequently Asked Questions
Is SerpNap better than Rank Math?
They serve different purposes. Rank Math excels at WordPress-integrated on-page SEO with 16 schema types, rank tracking, and content AI. SerpNap excels at site-wide auditing, technical SEO checks, and AI search optimization — and works on any website. Most professionals use both.
Does SerpNap offer schema markup like Rank Math?
Yes. SerpNap's Schema Generator creates JSON-LD structured data for any schema type. While Rank Math auto-generates schema within WordPress, SerpNap lets you generate schema for any platform and gives you the raw code to implement.
Can I track keyword rankings with SerpNap?
Not yet — keyword rank tracking is on our roadmap. Currently, we recommend using Google Search Console (free) for rank tracking alongside SerpNap for auditing. Rank Math Pro's rank tracking is a genuine advantage.
Should I use Rank Math's free version or SerpNap?
Use both. Rank Math (free) handles WordPress on-page optimization brilliantly. SerpNap adds technical auditing depth, AI search optimization, and the ability to audit competitor sites — things Rank Math can't do.
Does SerpNap slow down my website?
No. SerpNap is a standalone web tool — it doesn't install anything on your site. Unlike WordPress plugins that add code to every page load, SerpNap runs externally and has zero impact on your site's performance.
