Head-to-head review · Updated June 2026

Semrush vs Sitebulb: which one wins in 2026?

Semrush 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. Semrush has raised Acquired by Adobe for $1.9B (2026), Sitebulb has raised Bootstrapped; Semrush is the more-funded incumbent; Sitebulb is the leaner challenger.

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

Semrush

Pick Semrush if you want the cheaper option ($140/mo vs $18/mo); and you want the better-funded company (Acquired by Adobe for $1.9B (2026)); and SOC 2 Type 2 matters for your security review.

Pick

Sitebulb

Pick Sitebulb if you want the cheaper option ($18/mo vs $140/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 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.

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 Semrush wins
  • 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; Sitebulb doesn't yet.
  • Largest SEO database in the category with 25B+ keywords and 43T+ backlinks per Semrush's own reporting.
When Sitebulb wins
  • Budget is the constraint. Sitebulb starts at $18/mo vs Semrush's $140/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 Semrush 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 Semrush over Sitebulb

  1. Better-funded incumbent. Semrush has raised Acquired by Adobe for $1.9B (2026), giving it more runway and shipping velocity than Sitebulb (Bootstrapped).
  2. SOC 2 Type 2. Semrush carries SOC 2 Type 2; Sitebulb does not yet, which can hold up procurement.
  3. More verified reviews. Semrush has 3,434 G2 reviews vs Sitebulb's none on file, so the average rating carries more weight.
  4. Faster product velocity. Semrush has shipped 6 public launches in the last year vs Sitebulb's 0.
  5. More mature platform. Semrush (founded 2008) has had more time to harden the product than Sitebulb (2017).
  6. Wider integration ecosystem. Semrush integrates with 12 tools; Sitebulb ships 5.
  7. What users praise most. Largest SEO database in the category with 25B+ keywords and 43T+ backlinks per Semrush's own reporting.

Reasons to pick Sitebulb over Semrush

  1. Lower entry price. Sitebulb starts at $18/mo vs Semrush's $140/mo.
  2. More plan flexibility. Sitebulb offers 4 pricing tiers vs Semrush's 3, so there's a better chance one fits your team size.
  3. Built for the LLM era. Sitebulb was founded in 2017, built around AI search from day one; Semrush dates back to 2008 and is retrofitting.
  4. What users praise most. 300+ prioritized SEO hints with severity scoring and clear fix explanations, considered best-in-class for visual audits.
  5. 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 Semrush to Sitebulb

Export your saved queries and prompt panels from Semrush (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 againstSemrush's; one to two weeks of full reconciliation before you cancel Semrush. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.

From Sitebulb to Semrush

Same flow in reverse. Export from Sitebulb, import to Semrush. 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 Semrush 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, Semrush or Sitebulb?

Honestly: neither one fully solves the problem. Semrush 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 Semrush and Sitebulb cost?

Semrush starts at $140/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 Semrush and Sitebulb actually improve your AI visibility, or just measure it?

Both Semrush 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 Semrush 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.
