Everything a technical SEO audit needs, on your own computer
O2X – SEO Tool is a desktop application. Crawls run on your computer, results stay on your computer, and there is no monthly subscription. Each website is a project, so every crawl, audit, speed test and migration stays organised per client.
Crawl
Crawls 100% of a site safely: a pre-flight check estimates size, disk, memory and time, then the crawl runs in checkpointed chunks with polite speed presets and automatic pause on firewall blocks.
SEO Audit
176 checks in 13 categories – from status codes to AI search readiness – grouped by severity, each explained as what it is, why it matters and how to fix it, with a health score and every affected URL.
Structured Data
JSON-LD, Microdata and RDFa validated against the full Schema.org vocabulary and Google rich result rules, with a corrected copy and recommended markup per page type.
Robots.txt
Crawler access for Googlebot, Bing and AI bots, platform-specific rule recommendations, private pages that should be noindex, a URL tester and a suggested robots.txt.
Site migrations
Baseline of the old site, pre-launch checks on staging, automatic redirect mapping, redirect tests and post-launch monitoring, with a launch checklist.
Speed
Lighthouse lab tests and PageSpeed Insights for any page: Core Web Vitals, performance, accessibility, best practices and SEO scores.
Compare, list check, sitemaps
See what changed between two crawls, check status codes and redirects for any URL list, and generate XML sitemaps from a crawl.
White-label exports
Every table and report exports to Excel, CSV, HTML or PDF. With the Agency license your logo and details head every export and the tool is never named.
Why agencies choose a lifetime license
- Pay once. $219 for one computer or $649 for ten, including 12 months of updates. Renewing updates afterwards is optional (40% of the price per year), and the versions you already have keep working forever.
- Your clients’ data stays with you. Crawls, audits and reports are stored on your computer. The license check sends only the license key and a one-way hash of the computer id – never crawl data.
- Built to crawl politely. Speed presets, robots.txt rules and automatic block detection protect the sites you audit and your IP address.
- Made by SEO practitioners. O2X is built by the SEO team at O2 Digital for real client audits and migrations. Every issue carries the reminder that only an SEO specialist can confirm it for a given site.
