Claim This Listing - FreeSanityCheck.io is a software business based in Cornwall that builds specialized SaaS tools for SEO professionals and digital agencies. The company focuses on creating practical products designed to help marketers and agencies make better, data-led decisions rather than relying on guesswork. The company's product lineup includes three main tools: SEOTesting, a comprehensive SEO testing and reporting platform; InternalLinking, a tool that uncovers new internal link opportunities for existing and new content; and RankTracker, a free rank tracking tool built on Google Search Console data. Together, these tools address critical workflow challenges in search engine optimization. Founded by Nick Swan, SanityCheck.io aims to make SEO measurable and transparent. By leveraging Google Search Console and GA4 data, the suite of tools empowers users to conduct time-based SEO testing, split testing, content decay detection, and automated stakeholder reporting.

Here is a brutally honest, expert marketing analysis of the SanityCheck.io landing page.
This review focuses on optimizing your positioning as a Google Search Console (GSC) enhancement tool.
Right now, your landing page is likely suffering from the curse of knowledge. You know exactly what the software does, but a first-time visitor is left piecing together the puzzle.
Here is the strategic breakdown of your core landing page elements and how to fix them.
Your current hero text relies too heavily on technical features rather than the emotional payoff of using the tool.
Telling users that you "extract Search Console data" is a feature, not a benefit. It does not immediately communicate the end result, which is finding SEO quick wins and saving hours of spreadsheet analysis.
The subheadline is likely too vague. If a visitor has to read a paragraph to understand your software, they will bounce.
You need to shift from a feature-centric model to a benefit-driven framework.
Resources to help:
Your unique value is not clear within the first 5 seconds.
While visitors understand it has something to do with SEO and Google Search Console, the unique differentiator is buried. Why should they pay for SanityCheck when GSC is free?
If a visitor cannot instantly see how you bridge the gap between "raw data" and "actionable insights," your value proposition has failed.
You must immediately answer the question: "What is in it for me?"
Resources to help:
The first impression above the fold lacks a strong visual anchor.
B2B SaaS buyers need to see the product in action. If your hero section is just a wall of text on a plain background, it creates friction and doubt.
Users want to know what the dashboard looks like before they commit an email address to a free trial.
You need to optimize the visual hierarchy to guide the visitor's eye directly to the product's value and the CTA.
Resources to help:
Your messaging is trying to speak to everyone—from solo bloggers to enterprise SEO agencies.
When you speak to everyone, you speak to no one. The pain points of an agency owner managing 50 clients are vastly different from an in-house marketer trying to boost blog traffic.
Your current copy does not adequately agitate the specific pain of drowning in messy GSC data.
You must tailor your messaging to target the "Agitated Analyst"—the person tired of exporting CSVs and fighting with Excel pivots.
Resources to help:
If your button just says "Sign Up" or "Get Started," you are bleeding conversions.
These are high-friction, generic CTAs that demand work from the user without promising any immediate reward. They do not inspire action or reduce the perceived risk of signing up.
Your CTA needs to be highly visible, low-friction, and deeply tied to the value proposition.
Resources to help:
Here are specific, actionable rewrites you can implement today to see an immediate lift in conversion rates.
These adjustments are not just subjective copywriting tweaks; they are rooted in proven behavioral psychology.
By shifting from features to benefits, you lower the cognitive load on the user. They no longer have to translate what your software does into how it helps them—you have already done that work for them.
Using high-contrast, value-driven CTAs paired with risk-reversing microcopy reduces hesitation. When visitors see a clear dashboard image above the fold, it builds immediate trust and visual proof of your claims.
Implementing these strategic changes will decrease your bounce rate, increase time-on-page, and ultimately drive a higher percentage of visitors into your free trial funnel.

Product Positioning Score: 7.5/10
1. Problem-Solution Fit The core problem is highly relatable: Google Search Console (GSC) is a goldmine of SEO data, but its native interface is clunky, limited to 16 months, and terrible for spotting trends. SanityCheck’s solution—"Making Google Search Console actionable"—is a compelling answer. The fit is strong because it directly addresses the friction of manual data extraction.
2. Feature Communication The landing page relies slightly too heavily on SEO jargon rather than business outcomes. Phrases like "Striking Distance Keywords" and "Keyword Cannibalization" speak to practitioners, but they describe functionality rather than the benefit. The true benefit isn't "finding striking distance keywords"—it’s "increasing traffic in days without writing new content."
3. Market Positioning The positioning straddles the line between "everyday website owners" and "technical SEO professionals." Because the tool requires a baseline understanding of concepts like CTR and cannibalization, targeting absolute beginners dilutes the message. The real power users here are in-house marketers, content leads, and agency SEOs who are tired of exporting GSC data into messy Excel spreadsheets.
4. Competitive Angle In a market saturated with expensive, bloated all-in-one SEO suites (like Ahrefs or Semrush), SanityCheck has a brilliant, lightweight competitive wedge. It doesn't crawl the whole web; it acts as an intelligence layer on top of your existing, highly accurate Google data. Its SEO A/B testing feature is a massive differentiator that proves the ROI of a marketer's work.
SanityCheck has built a highly practical, high-ROI tool that solves a universal headache for search marketers. The product-solution fit is already there. To push conversions higher, the positioning simply needs to mature from explaining what the software does (data extraction and alerting) to what the user achieves (saving hours of manual reporting and proving the ROI of their SEO experiments).
