Discover Landing Page Audit Tool Pricing (2026 Comparison)
Bottom line up front
Most “audit” tools charge a subscription for an adjacent job: Unbounce from $29/month (builder), Hotjar from $32/month (behavior), Crazy Egg from $49/month (heatmaps), SEMrush $139.95/month (SEO platform). Only Nebula audits the conversion layer itself - free, no signup, no traffic required - with a $97 one-time fix kit instead of a monthly bill. Free utilities that do not check conversion: PageSpeed Insights, HubSpot Website Grader (email-gated), Screaming Frog (500-URL free tier).

Detailed pricing breakdowns
Visual analytics (heatmaps, A/B testing)
Crazy Egg Pricing
Crazy Egg pricing starts at $49/month (Starter), with Plus at $99/month and Pro at $249/month. It provides heatmaps, recordings, and A/B testing - all of which require existing traffic. It visualizes behavior but does not diagnose conversion structure, and it needs visitor volume before it produces anything. Nebula scores the conversion structure of any URL instantly, free, with no traffic required.

Behavior analytics (heatmaps)
Hotjar Pricing
Hotjar has a free tier (35 sessions per day) and paid plans from $32/month (Plus) and $80/month (Business). It shows you what visitors do with heatmaps and recordings - but it needs existing traffic, and it does not diagnose why a page fails to convert. If your headline does not match your ad, Hotjar shows people leaving; it does not name the message-match failure. Nebula diagnoses that structure on any URL, free, with no traffic required.

Technical SEO platform
SEMrush Site Audit Pricing
SEMrush Pro costs $139.95/month and includes Site Audit as one module inside a full SEO platform. It runs 130+ technical SEO checks across a whole site - crawl errors, broken links, metadata - but it does not check conversion structure. A landing page that is not converting paid traffic will pass a SEMrush crawl while the real problem (headline mismatch, weak CTA, missing trust) stays invisible. Nebula checks the conversion layer for free, with a $97 one-time fix kit.

Landing page builder
Unbounce Pricing
Unbounce pricing starts at $29/month and goes up to $249/month - the AI Smart Traffic feature only exists on the top tier, and the 14-day trial requires a credit card. It is a builder, not an auditor: it only optimizes pages built inside its platform. If you already have a landing page on Webflow, Framer, Shopify, or WordPress and want to know why it is not converting, Nebula audits any public URL for free, with a $97 one-time fix kit instead of a subscription.

Why pricing matters when you are bleeding ad spend
A founder running paid traffic to a page that does not convert is paying twice: the ad cost every day, and a subscription for a tool that does not diagnose the actual problem. Before you add a recurring bill, run a free conversion audit. If the leak is message match, CTA, or trust - the most common causes - no heatmap or SEO crawl will name it. The fix is usually a one-time change, not a monthly platform.
Frequently asked questions
What is the cheapest landing page audit tool?
Nebula (free audit, no signup, $97 optional one-time fix kit), Google PageSpeed Insights (free), and HubSpot Website Grader (free but email-gated, homepage only) are the free options. Screaming Frog is free up to 500 URLs, then £199/year. Hotjar has a free tier limited to 35 sessions per day.
Which landing page audit tools require a subscription?
Hotjar (from $32/month), Crazy Egg (from $49/month), Unbounce (from $29/month, $249/month for Smart Traffic), and SEMrush (from $139.95/month) are subscription-based. Nebula is free for the audit with a one-time $97 fix kit - no subscription.
Is there a free alternative to Crazy Egg or Hotjar?
Yes - Nebula audits any public landing page for free, with no signup and no traffic required. The difference: Nebula checks conversion structure (message match, CTA, trust, above-fold) rather than showing behavior heatmaps, which need existing visitor sessions.
Is Unbounce pricing worth it for a single landing page?
Usually not. Unbounce starts at $29/month and only optimizes pages built inside its platform - the AI Smart Traffic feature that justifies the price requires the $249/month tier. For an existing page, a free conversion audit with a $97 one-time fix kit is the higher-leverage first step.
Why is SEMrush $139.95/month?
SEMrush is a full SEO platform - keyword research, rank tracking, competitor analysis, plus Site Audit as one module. If you only need to know why one landing page is not converting paid traffic, you are paying for a platform you will not use. A conversion audit checks the actual problem for free.
Do any of these tools check conversion structure, not just speed or SEO?
Only Nebula checks 9 observable conversion conditions on the public page: headline message match against the ad, CTA clarity, trust/social proof, above-fold structure, mobile CTA, load speed, ad signals, SEO foundations, and AI citation readiness. Those checks do not predict conversion from paid traffic. PageSpeed checks speed; Hotjar and Crazy Egg show behavior; SEMrush and Screaming Frog check technical SEO.
