Contentful 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. Contentful has raised $330M+ raised, Sitebulb has raised Bootstrapped; Contentful is the more-funded incumbent; Sitebulb is the leaner challenger.
Contentful 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.
Pick Contentful if you want the cheaper option ($0/mo vs $18/mo); and you trust traction signals — they list 10 customers, Sitebulb lists 6; and you want the better-funded company ($330M+ raised); and SOC 2 Type 2 matters for your security review.
Pick Sitebulb if you want the cheaper option ($18/mo vs $0/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.

What each one ships that the other doesn't. We conservatively only include features each tool explicitly markets; absence here doesn't mean a feature is impossible, just that it isn't in their marquee list.
Export your saved queries and prompt panels from Contentful (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 againstContentful's; one to two weeks of full reconciliation before you cancel Contentful. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
Same flow in reverse. Export from Sitebulb, import to Contentful. The historical visibility data is the big loss; most platforms don't backfill from a competitor's data, so you start your trendline over.
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.

Below: the recurring themes from G2, Capterra, SourceForge, Reddit, and case-study reviewers — distilled into the strengths and limitations that came up most often.
Both Contentful 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.
Same shape, different pairs. Pick a comparison that shares a tool with this one.
Honestly: neither one fully solves the problem. Contentful 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 Contentful 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.
Contentful starts at $0/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.
Both Contentful 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.
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.

GrowthManager.ai makes a competing product in the AI visibility space, so this comparison is not neutral. Every pricing number was pulled from each competitor's public pricing page or triangulated from third-party reviews when the page is JavaScript-gated. Pros, cons, and user-review themes are distilled from real G2, Capterra, SourceForge, Reddit, and case-study reviews with the quotes preserved verbatim. We update this comparison whenever the underlying data changes.
