HONEST ALTERNATIVE · SEO + AI VISIBILITY
Sitebulb is a respected desktop crawler prized for its visual site architecture diagrams and deep technical audits — but it requires installation, a paid licence, and produces reports that can't be shared as a live URL. DeepSEOAnalysis is a free, web-based alternative: complete technical SEO audit, real CrUX field data, CMS-aware fix instructions, and a GEO score for AI-visibility. No download, no licence, no email gate.
At a glance
The useful answer is not “which tool is best?” It is which tool fits the job you need done this week.
| Criterion | Competitor | DeepSEOAnalysis |
|---|---|---|
| Access model | Paid desktop application (Mac and Windows). Requires installation. Trial available but full use requires a paid licence. No free tier for ongoing use. | Web-based. No installation, no licence required. Full audit is free with no signup and no email gate. |
| AI visibility / GEO | Traditional technical SEO crawler focused on site architecture, internal links, and on-page signals. No GEO scoring, AI crawler checks, or llms.txt audit. | GEO score covers all five AI visibility signals: AI crawler access, llms.txt, FAQPage/HowTo schema, question-heading ratio, and content chunkability. |
| Core Web Vitals | Integrates PageSpeed Insights lab data for performance metrics. Desktop-crawled data. | Real Google CrUX field data from actual Chrome users — not just synthetic lab scores. Lab scores also shown for diagnosis. |
| Crawl visualisation | Sitebulb's strongest feature: visual crawl maps, click-depth diagrams, and issue priority heatmaps. Very strong for understanding site architecture visually. | Audit report is text + structured data; no visual crawl diagram. Prioritised issue list with severity, category, and fix detail. |
| Shareable reports | Reports can be exported as HTML or PDF from within the app. Requires the recipient to open the export — no live shareable URL. | Every audit has a public shareable URL. Paste into a ticket, email, or Slack message — recipient opens instantly in a browser, no account needed. |
| CMS-specific fixes | Excellent at surfacing technical issues; fix language is generally technical and not CMS-specific. | CMS-aware fix instructions name the plugin setting, theme file, or CMS-specific path — not generic advice. |
| Best fit | Professional SEO consultants and agencies who need deep visual site architecture analysis, large crawls (100k+ pages), and detailed technical reports for complex sites. | Founders, developers, and in-house teams who want an instant free audit with AI-visibility scoring, real CrUX data, and a shareable URL — without installing software. |
What each product is
Sitebulb is strongest for professional SEO consultants who need visual crawl diagrams, large-scale crawls, and detailed site architecture analysis — particularly for complex enterprise sites where click-depth heatmaps and link equity visualisation are core deliverables.
DeepSEOAnalysis is strongest when you need an instant audit without installation, a free result with no account required, AI-visibility scoring that Sitebulb doesn't offer, and a shareable URL for the report — accessible to anyone without software.

FAQ
Sitebulb offers a free trial but not an ongoing free tier. After the trial, a paid licence is required. DeepSEOAnalysis is free indefinitely with no email gate — the full audit report is available on every crawl.
Not natively. Sitebulb is a technical SEO crawler focused on site architecture, internal links, and on-page signals. It does not audit AI crawler access, llms.txt, FAQPage schema for citation readiness, or content chunkability for LLM retrieval.
For very large sites (100k+ pages), Sitebulb's desktop crawler handles scale that a web-based tool can't match easily. DeepSEOAnalysis crawls up to 50 pages free and up to 1,000 on paid plans. For most marketing and content sites, 1,000 pages is sufficient.
Installation adds friction for quick audits, client demos, and team sharing. DeepSEOAnalysis runs in a browser — you can audit a site from any machine, share the report URL with a developer or client, and get results without IT permission or licence management.
