Pick
OnCrawl
Pick OnCrawl if you trust traction signals — they list 10 customers, Semrush lists 6.
Head-to-head review · Updated June 2026
OnCrawl vs Semrush: which one wins in 2026?
OnCrawl and Semrush 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. Semrush 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
Semrush
Pick Semrush if you want the better-funded company (Acquired by Adobe for $1.9B (2026)); 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 Semrush
Semrush has raised Acquired by Adobe for $1.9B (2026) (Adobe acquisition closed April 2026). Founded by Oleg Shchegolev, Dmitry Melnikov, based in Boston, MA. On their site they list 6 named customers including Decathlon, Quora, Booking.com, Samsung. Pricing starts at $140/mo.
All-in-one SEO and content marketing platform with a growing AI search visibility module.
What people praise
- Largest SEO database in the category with 25B+ keywords and 43T+ backlinks per Semrush's own reporting.
- Toolset breadth is unmatched: keyword research, rank tracking, backlinks, site audit, content marketing, PPC, and social all in one.
- AI Overviews tracking and AI search visibility features were rolled out earlier than most legacy competitors.
- Sheer volume of integrations (HubSpot, Google, Wix, Zapier, Trello) makes it easy to wire into existing workflows.
Where it falls short
- Per-seat pricing is brutal: additional user seats cost $45 to $100/month each on top of the base plan.
- Add-ons like the Trends toolkit add another $289/month, so real-world cost is far above sticker.
- Pro plan has hard 500-keyword tracking limit, forcing upgrades long before features are needed.
- Site audit is capped per project and crawl, making it weaker than dedicated crawlers like Screaming Frog at scale.

When each one wins
When OnCrawl wins
- You're enterprise and need to call a reference. OnCrawl lists 10 named customers; Semrush lists 6.
- JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
When Semrush wins
- Budget is the constraint. Semrush starts at $140/mo vs OnCrawl's $∞/mo, so on a per-seat basis it's the cheaper way in.
- You want the better-funded incumbent. Semrush has raised Acquired by Adobe for $1.9B (2026), giving it more runway and shipping velocity.
- Procurement requires SOC 2 Type 2. Semrush 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

- EU data residency. OnCrawl is HQ'd in Bordeaux, France, which simplifies GDPR data-processor agreements for European buyers.
Reasons to pick Semrush over OnCrawl
- Lower entry price. Semrush publishes a clear entry tier at $140/mo; OnCrawl gates pricing.
- Public pricing. Semrush publishes 3 tiers on its website; OnCrawl requires a sales conversation.
- Better-funded incumbent. Semrush has raised Acquired by Adobe for $1.9B (2026), giving it more runway and shipping velocity than OnCrawl.
- SOC 2 Type 2. Semrush carries SOC 2 Type 2; OnCrawl does not yet, which can hold up procurement.
- More verified reviews. Semrush has 3,434 G2 reviews vs OnCrawl's none on file, so the average rating carries more weight.

Switching from one to the other
From OnCrawl to Semrush
Export your saved queries and prompt panels from OnCrawl (most tools support CSV export). Most Semrush setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Semrush'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 Semrush to OnCrawl
Same flow in reverse. Export from Semrush, 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 Semrushare 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 Semrush?
Honestly: neither one fully solves the problem. OnCrawl and Semrush 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 Semrush cost?
OnCrawl starts at Custom. Semrush starts at $140/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 Semrush actually improve your AI visibility, or just measure it?
Both OnCrawl and Semrush 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 Semrush?
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.
