OnCrawl

Head-to-head review · Updated June 2026
OnCrawl vs Page Optimizer Pro: which one wins in 2026?
OnCrawl and Page Optimizer Pro 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. Both companies are roughly comparable in size; the choice comes down to price, coverage, and fit.
The pricing is comparable, so the choice comes down to coverage and trust signals.
The verdict
Pick
Page Optimizer Pro
Page Optimizer Pro is the right pick if your team prefers their approach and pricing fits.
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 Page Optimizer Pro
Page Optimizer Pro has raised Bootstrapped. Founded by Kyle Roof, based in London, UK. Pricing starts at $40/mo.
On-page SEO optimization with data-driven recommendations.
What people praise
- Recommendations are grounded in Kyle Roof's 400+ scientific SEO tests and a granted Google ranking-factor patent, which gives users more confidence than competitor tools that rely on correlation alone.
- Reviewers consistently report pages moving to positions 1-3 within days of applying the on-page edits the tool recommends.
- POP Watchdog is the only tool in the category that alerts you when a ranking drops and tells you exactly what changed on the page or in the SERP.
- Credits can be bought one-off without committing to a monthly subscription, which makes it accessible for freelancers running occasional audits.
Where it falls short
- Credit system is opaque and burns through fast , users want a flat unlimited tier without the per-report accounting.
- Interface has a steep learning curve and reviewers describe it as less intuitive than Surfer or Frase, with key features hidden under multiple clicks.
- AI Writer outputs large blocks of unstructured text that need heavy editing before publishing.
- Integrations are thin compared to Semrush or Moz , no native CMS publishing, no Search Console import.

When each one wins
When OnCrawl wins
- You're enterprise and need to call a reference. OnCrawl lists 10 named customers; Page Optimizer Pro lists 0.
- JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
When Page Optimizer Pro wins
- Budget is the constraint. Page Optimizer Pro starts at $40/mo vs OnCrawl's $∞/mo, so on a per-seat basis it's the cheaper way in.
- Recommendations are grounded in Kyle Roof's 400+ scientific SEO tests and a granted Google ranking-factor patent, which gives users more confidence than competitor tools that rely on correlation alone.
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

- Wider integration ecosystem. OnCrawl integrates with 8 tools; Page Optimizer Pro ships 3.
- 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 Page Optimizer Pro over OnCrawl

- Public pricing. Page Optimizer Pro publishes 4 tiers on its website; OnCrawl requires a sales conversation.
- More verified reviews. Page Optimizer Pro has 20 G2 reviews vs OnCrawl's none on file, so the average rating carries more weight.

Switching from one to the other
From OnCrawl to Page Optimizer Pro
Export your saved queries and prompt panels from OnCrawl (most tools support CSV export). Most Page Optimizer Pro setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Page Optimizer Pro'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 Page Optimizer Pro to OnCrawl
Same flow in reverse. Export from Page Optimizer Pro, 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 Page Optimizer Proare 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 Page Optimizer Pro?
Honestly: neither one fully solves the problem. OnCrawl and Page Optimizer Pro 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 Page Optimizer Pro cost?
OnCrawl starts at Custom. Page Optimizer Pro starts at $40/mo. 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.
Do OnCrawl and Page Optimizer Pro actually improve your AI visibility, or just measure it?
Both OnCrawl and Page Optimizer Pro 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 Page Optimizer Pro?
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.
