Pick
OnCrawl
OnCrawl is the right pick if your team prefers their approach and pricing fits.
Head-to-head review · Updated June 2026
OnCrawl vs Siteimprove: which one wins in 2026?
OnCrawl and Siteimprove both claim to do the same thing: tell you where your brand shows up in AI search. They go about it differently enough that the choice matters. Siteimprove is the more-funded incumbent; OnCrawl is the leaner challenger.
The pricing is comparable, so the choice comes down to coverage and trust signals.
The verdict
Pick
Siteimprove
Pick Siteimprove if you need broader AI platform coverage (5 platforms vs 0); and you want the better-funded company (Acquired by Nordic Capital in 2020 (~€500M)); and SOC 2 Type 2 matters for your security review.
If neither is right, GrowthManager.ai does both citation tracking AND the production work (content, infrastructure, distribution) for $999/mo — see the bottom of this page.
The case for OnCrawl
Founded by Francois Goube, Tanguy Moal, based in Bordeaux, France. On their site they list 10 named customers including Adidas, L'Oreal, Ticketmaster, Harrods.
Enterprise SEO data platform combining crawl, logs, and AI insights.
What people praise
- JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
- Log file analyzer processes 500M+ log lines per day, surfacing how Googlebot, Bingbot, and AI crawlers actually behave on the site.
- Cross-references crawl data, server logs, GSC, GA4, Adobe Analytics, and Majestic backlinks in one analysis - few competitors integrate all five sources.
- 100% unsampled data analysis appeals to enterprise SEOs frustrated with GA4 sampling and Search Console limits.
Where it falls short
- No public pricing - book-a-demo gating means SMBs and indie consultants are filtered out before evaluation.
- Capterra rating of 3.8 is the lowest among major technical SEO crawlers, with reviewers citing UI complexity and pricing opacity.
- Steep learning curve - the platform assumes data-science fluency, which leaves marketers needing a technical SEO specialist to extract value.
- Self-serve onboarding is limited; complex multi-source setups (logs plus crawl plus analytics) typically need OnCrawl's customer success team.
The case for Siteimprove
Siteimprove has raised Acquired by Nordic Capital in 2020 (~€500M) (Nordic Capital majority acquisition 2020). Founded by Morten Ebbesen, based in Copenhagen, Denmark. On their site they list 10 named customers including Google, Microsoft, Amazon, IBM. They cover 5 AI platforms. Pricing starts at Custom quote.
Digital experience optimization with SEO, accessibility, and content quality.
What people praise
- Recognized as a G2 Leader in Digital Accessibility for six consecutive years, the longest streak in the category.
- Modular suite (Accessibility, SEO, QA, Analytics, Policy, Content) lets enterprises pick exactly the modules they need.
- Native WCAG 2.2 AA validation with in-code highlights and remediation tips, plus European Accessibility Act readiness.
- New agentic content intelligence platform launches Accessibility, Analytics, SEO/AEO, and Content Strategy AI agents.
Where it falls short
- Steep learning curve flagged in many G2 reviews; configuration is notably harder than simpler accessibility checkers.
- No public pricing; published Vendr benchmarks show $12K-$70K+/year, putting it out of reach for SMBs.
- Automated testing cannot detect all accessibility issues, so manual audits remain necessary for legal compliance.
- Limited Joomla integration and unoptimized PDF exports are recurring complaints in reviewer feedback.

When each one wins
When OnCrawl wins
- JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
When Siteimprove wins
- Platform coverage matters. Siteimprove monitors 5 AI platforms; OnCrawl covers 0.
- You want the better-funded incumbent. Siteimprove has raised Acquired by Nordic Capital in 2020 (~€500M), giving it more runway and shipping velocity.
- Procurement requires SOC 2 Type 2. Siteimprove has it; OnCrawl doesn't yet.
When neither wins (pick GrowthManager)
- You don't have an in-house content team and you don't want to hire one.
- You want one $999/mo invoice instead of stacking OnCrawl plus an agency.
- You need the team that measures to also act on the data, in the same week.
- You're a B2B SaaS, services firm, or e-commerce brand at $20K+ MRR.
Reasons to pick one over the other
Reasons to pick OnCrawl over Siteimprove
- Faster product velocity. OnCrawl has shipped 5 public launches in the last year vs Siteimprove's 0.
- Built for the LLM era. OnCrawl was founded in 2013, built around AI search from day one; Siteimprove dates back to 2003 and is retrofitting.
- What users praise most. JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
Reasons to pick Siteimprove over OnCrawl
- Public pricing. Siteimprove publishes 3 tiers on its website; OnCrawl requires a sales conversation.
- Broader AI platform coverage. Siteimprove tracks visibility across 5 AI engines vs OnCrawl's 0.
- Better-funded incumbent. Siteimprove has raised Acquired by Nordic Capital in 2020 (~€500M), giving it more runway and shipping velocity than OnCrawl.
- SOC 2 Type 2. Siteimprove carries SOC 2 Type 2; OnCrawl does not yet, which can hold up procurement.
- More mature platform. Siteimprove (founded 2003) has had more time to harden the product than OnCrawl (2013).
- What users praise most. Recognized as a G2 Leader in Digital Accessibility for six consecutive years, the longest streak in the category.
Switching from one to the other
From OnCrawl to Siteimprove
Export your saved queries and prompt panels from OnCrawl (most tools support CSV export). Most Siteimprove setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Siteimprove's data againstOnCrawl's; one to two weeks of full reconciliation before you cancel OnCrawl. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From Siteimprove to OnCrawl
Same flow in reverse. Export from Siteimprove, import to OnCrawl. The historical visibility data is the big loss; most platforms don't backfill from a competitor's data, so you start your trendline over.
From either to GrowthManager.ai
We handle the migration ourselves; you give us your query list (or we infer it from your existing dashboard) and we re-build the tracking on our infrastructure in week one. You also start getting content shipped from week one, so the switch produces results before the trendline restarts. The conversation that kicks this off is a 20-minute call.

A third option
Both OnCrawl and Siteimproveare tracking tools. They tell you what's wrong with your AI visibility. Neither one fixes it. That's our pitch for GrowthManager.ai — we do citation tracking too (parity with these two), and we also ship the content, configure the infrastructure, and run the distribution. $999/mo, managed end-to-end. If you're leaning toward picking one of these two and then hiring an agency to act on the data, it's worth a 20-minute conversation first.

Frequently asked questions
Which is better, OnCrawl or Siteimprove?
Honestly: neither one fully solves the problem. OnCrawl and Siteimprove are tracking tools — they tell you where your brand shows up in AI answers but don't change the answer. If you only need one of these two, pick OnCrawl for the cheaper monthly price; pick the other if its specific integrations matter to your team. Our actual editorial pick is GrowthManager.ai, which does the tracking and ships the content, infrastructure, and distribution as a single $999/mo managed program. Disclosure: we publish this comparison and make GrowthManager.
How much do OnCrawl and Siteimprove cost?
OnCrawl starts at Custom. Siteimprove starts at Custom quote. Both have higher-tier plans for larger workspaces. GrowthManager.ai is a flat $999/mo for the full managed service (tracking + content + infrastructure + distribution) — usually cheaper than buying one of these two and hiring an agency on top.
Which AI platforms do OnCrawl and Siteimprove cover?
OnCrawl covers an undisclosed number of AI platforms. Siteimprove covers 5. Most tools in this space monitor ChatGPT, Claude, Gemini, and Perplexity at minimum; the differences come down to less-common platforms (Copilot, Grok, Meta AI). GrowthManager.ai monitors the same four primary platforms and acts on the data.
Do OnCrawl and Siteimprove actually improve your AI visibility, or just measure it?
Both OnCrawl and Siteimprove are measurement tools. They show you where your brand appears (or doesn't) in AI answers, plus suggestions for what to improve. Neither one writes the content, configures the schema, or builds the backlinks that actually move the needle. To do that you need an in-house content team or an agency. GrowthManager.ai is the agency — and we include the tracking, so you don't pay twice.
What's the GrowthManager.ai alternative to OnCrawl and Siteimprove?
GrowthManager.ai is a managed AI visibility program. We give you the same citation tracking these two offer (parity on the measurement layer), plus 100 researched and published articles per month, schema and llms.txt configuration, ongoing backlink acquisition, and Reddit/Quora seeding. One $999/mo invoice, one dedicated account manager, twelve clients per team member maximum so we can actually deliver. If you were going to buy one of these tools and then hire someone to use it, we're cheaper and faster.
