Head-to-head review · Updated June 2026
Schema App vs Sitebulb: which one wins in 2026?
Schema App and Sitebulb 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. Schema App has raised Bootstrapped, Sitebulb has raised Bootstrapped; Both companies are roughly comparable in size; the choice comes down to price, coverage, and fit.
Sitebulb is cheaper out the gate, but that's not the only thing that matters. The right pick depends on which dimension matters most for you.
The verdict
Pick
Sitebulb
Pick Sitebulb if you want the cheaper option ($18/mo vs $100/mo).
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 Schema App
Schema App has raised Bootstrapped. Founded by Martha van Berkel, Mark van Berkel, based in Guelph, Canada. On their site they list 9 named customers including SAP, Wells Fargo, AdventHealth, Gusto. Pricing starts at $100/mo.
Enterprise schema markup and knowledge graph management platform.
What people praise
- Deploys schema markup at enterprise scale, with Wells Fargo case study showing 1,200+ pages migrated from plugin-based markup.
- Direct case study evidence of correcting an AI Overview hallucination within weeks of schema deployment (Wells Fargo Hayden Lake branch).
- Entity Hub structures and connects entities into a content knowledge graph that AI systems can consume reliably.
- SOC 2 Type II compliant, which is a hard requirement for the regulated enterprise buyers it targets.
Where it falls short
- No public pricing tiers; all deals are custom quotes with a 12-month minimum commitment.
- Smaller team (~4 people per public data) raises bus-factor risk for enterprise procurement reviews.
- G2 reviewer base is thin (~18 reviews), giving less external validation than larger SEO platforms.
- Attribution is complex; tying schema markup to revenue or organic click gains is not straightforward.
The case for Sitebulb
Sitebulb has raised Bootstrapped. Founded by Patrick Hathaway, Gareth Brown, based in Banbury, UK. On their site they list 6 named customers including Amazon, Mailchimp, Macy's, Yahoo. Pricing starts at $18/mo.
Desktop and cloud SEO auditing tool for agencies.
What people praise
- 300+ prioritized SEO hints with severity scoring and clear fix explanations, considered best-in-class for visual audits.
- JavaScript crawling is included at no extra cost on every tier, unlike Screaming Frog where JS rendering is a premium feature.
- Only crawler offering both desktop (up to 500K URLs) and cloud (up to 10M URLs) so teams can scale from solo to enterprise.
- Visual data presentation with charts and graphs is widely cited as the most intuitive in the technical SEO category.
Where it falls short
- Resource-intensive on large sites; a 100K-page JS-rendered crawl can take 8-12 hours and consume 8GB+ RAM.
- No keyword research, backlink analysis, rank tracking, or content optimization, so it must be paired with another tool.
- ~0.20% market share vs Screaming Frog's 15.41% means fewer community tutorials and forum answers.
- Desktop pricing is not visible on the public pricing page without selecting a currency, hurting buyer transparency.

When each one wins
When Schema App wins
- You're enterprise and need to call a reference. Schema App lists 9 named customers; Sitebulb lists 6.
- Procurement requires SOC 2 Type 2. Schema App has it; Sitebulb doesn't yet.
- Deploys schema markup at enterprise scale, with Wells Fargo case study showing 1,200+ pages migrated from plugin-based markup.
When Sitebulb wins
- Budget is the constraint. Sitebulb starts at $18/mo vs Schema App's $100/mo, so on a per-seat basis it's the cheaper way in.
- 300+ prioritized SEO hints with severity scoring and clear fix explanations, considered best-in-class for visual audits.
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 Schema App 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 Schema App over Sitebulb
- More named customers. Schema App lists 9 customers vs Sitebulb's 6, including SAP, Wells Fargo, AdventHealth.
- SOC 2 Type 2. Schema App carries SOC 2 Type 2; Sitebulb does not yet, which can hold up procurement.
- Higher G2 rating. Schema App averages 4.8/5 on G2 across 18 reviews; Sitebulb averages 4.5.
- Faster product velocity. Schema App has shipped 4 public launches in the last year vs Sitebulb's 0.
- What users praise most. Deploys schema markup at enterprise scale, with Wells Fargo case study showing 1,200+ pages migrated from plugin-based markup.
Reasons to pick Sitebulb over Schema App
- Lower entry price. Sitebulb starts at $18/mo vs Schema App's $100/mo.
- More plan flexibility. Sitebulb offers 4 pricing tiers vs Schema App's 3, so there's a better chance one fits your team size.
- What users praise most. 300+ prioritized SEO hints with severity scoring and clear fix explanations, considered best-in-class for visual audits.
- EU data residency. Sitebulb is HQ'd in Banbury, UK, which simplifies GDPR data-processor agreements for European buyers.
Switching from one to the other
From Schema App to Sitebulb
Export your saved queries and prompt panels from Schema App (most tools support CSV export). Most Sitebulb setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Sitebulb's data againstSchema App's; one to two weeks of full reconciliation before you cancel Schema App. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From Sitebulb to Schema App
Same flow in reverse. Export from Sitebulb, import to Schema App. 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 Schema App and Sitebulbare 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, Schema App or Sitebulb?
Honestly: neither one fully solves the problem. Schema App and Sitebulb 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 Sitebulb 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 Schema App and Sitebulb cost?
Schema App starts at $100/mo. Sitebulb starts at $18/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 Schema App and Sitebulb actually improve your AI visibility, or just measure it?
Both Schema App and Sitebulb 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 Schema App and Sitebulb?
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.
