| Primary function | Privacy-first web analytics — Fathom provides pageviews, unique visitors, bounce rate, top pages, referrers, countries, devices, and goal conversions in a clean single-screen dashboard. No cookies, no personal data, no consent banner required. From $14/mo for 100k pageviews. Founded in 2018 by Jack Ellis and Paul Jarvis; EU-isolated data option available. | Technical SEO audit platform — schema.org markup validation, Core Web Vitals diagnosis (LCP, INP, CLS element-level), canonical hygiene, indexation status, and structured data server-rendering verification |
|---|
| Privacy and cookie consent | Core differentiator — Fathom does not use cookies, does not collect personal data, and does not require a cookie consent banner for EU, UK, or US visitors. Uses a privacy-first approach that counts pageviews via a unique hash method without identifying individual users. Compliant with GDPR, UK GDPR, CCPA, PECR, and ePrivacy Directive out of the box. | No cookies, no personal data processing of your visitors — DeepSEOAnalysis fetches public page HTML and CrUX field data; there is nothing to consent to for your visitors |
|---|
| Script size and CWV impact | Fathom's script is approximately 2KB and loads asynchronously — negligible CWV impact. Significantly lighter than Google Analytics 4 (45KB+). Recommended for teams who prioritise Core Web Vitals performance. Fathom's own documentation highlights the performance advantage over GA4. | No analytics script added to your pages — DeepSEOAnalysis reads your existing page HTML and CrUX field data from the outside; no code is installed on your site |
|---|
| Traffic analytics | Pageviews, unique visitors, average time on site, bounce rate, top pages with their pageview counts, referrers, countries, devices, browsers, and UTM campaign attribution — all in one clean dashboard. Real-time visitor counter. No sampling. Unlimited data retention. | No traffic analytics — DeepSEOAnalysis is a technical SEO audit tool; use Fathom or Google Search Console for traffic volume and source data, and DeepSEOAnalysis for on-page technical quality assessment |
|---|
| Goal conversion tracking | Fathom custom goals track page visits, external link clicks, and custom JavaScript events (button clicks, form submissions, etc.). Goal completions visible in the main dashboard alongside traffic data. Conversion rates calculated automatically. Revenue tracking for e-commerce via JavaScript API. | No goal or conversion tracking — DeepSEOAnalysis diagnoses technical issues affecting search ranking rather than tracking user conversion behaviour on your pages |
|---|
| Core Web Vitals | Fathom does not natively surface Core Web Vitals data. You can instrument custom Fathom events using the PerformanceObserver API to track LCP, INP, and CLS as goal events — but this requires custom JavaScript implementation and the metrics appear in Fathom's goal completion section, not in a dedicated CWV dashboard. | Native CWV diagnosis from CrUX field data at p75 — the threshold Google uses for ranking signals. Identifies the specific HTML element causing LCP delay, diagnoses INP and CLS, and verifies schema server-rendering. No custom implementation required. |
|---|
| EU isolation | Fathom offers an EU-isolated data option: all analytics data processed and stored exclusively on EU servers. This is distinct from Plausible (also EU-based) in that Fathom was founded in Canada but offers explicit EU isolation for customers who require it. EU isolation available on all plans. | No data storage of your visitors — DeepSEOAnalysis processes public page HTML; no geographic data residency requirements apply |
|---|
| Uptime and reliability | Fathom emphasises infrastructure reliability — script loaded from a global CDN; 99.99% uptime SLA on paid plans. Script not blocked by most ad blockers (unlike GA4 which is blocked by many privacy extensions). Fathom's lower profile means fewer users actively trying to block it. | No script to block or fail — DeepSEOAnalysis runs as an external audit; your site's CWV data comes from CrUX which Google collects from real Chrome users |
|---|
| Pricing | From $14/mo for 100k monthly pageviews; $24/mo for 200k; $44/mo for 500k; $74/mo for 1M; custom for higher. Annual billing discounts available. Single price tier includes all features — no separate plans for goals or data retention. | Free for all URL audits with no email gate; Pro $24/mo; Agency $89/mo |
