Head-to-head review · Updated June 2026
Sitebulb vs Writesonic GEO: which one wins in 2026?
Sitebulb and Writesonic GEO 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. Sitebulb has raised Bootstrapped, Writesonic GEO has raised $2.72M raised; Writesonic GEO is the more-funded incumbent; Sitebulb is the leaner challenger.
Sitebulb is cheaper out the gate, but Writesonic GEO tracks more AI platforms. The right pick depends on which dimension matters most for you.
The verdict
★ Our pick
Pick
Writesonic GEO
Pick Writesonic GEO if you want the cheaper option ($79/mo vs $18/mo); and you need broader AI platform coverage (4 platforms vs 0); and you trust traction signals — they list 10 customers, Sitebulb lists 6; 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 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.
The case for Writesonic GEO
Writesonic GEO has raised $2.72M raised (Seed (September 2021, $2.6M)). Founded by Samanyou Garg, based in San Francisco, CA. On their site they list 10 named customers including Amazon, Unilever, Acer, OECD. They cover 4 AI platforms. Pricing starts at $79/mo.
YC-backed AI growth engine combining GEO visibility monitoring with a content production engine powered by 120M+ proprietary AI chatbot conversations.
What people praise
- Tracks 10 AI platforms including ChatGPT, Claude, Gemini, Perplexity, Copilot, Grok and DeepSeek, broader than most dedicated GEO tools.
- Action Center turns visibility gaps into prioritized off-page, on-page and technical task lists rather than dashboards alone.
- Citation gap analysis surfaces sources citing competitors but not you, with ready-made outreach email templates included.
- Sentiment analysis at Growth tier shows whether AI assistants describe your brand positively or negatively, not just whether they mention you.
Where it falls short
- The Action Center is gated to Enterprise pricing, meaning self-serve tiers only get visibility data without actionable recommendations.
- Starter tier only tracks ChatGPT, forcing a jump to $199/mo Basic to monitor Gemini and Google AI Overviews.
- GEO insights feel surface-level versus dedicated platforms like Profound, since Writesonic optimizes for SEO and content workflows first.
- CMS integrations limited to WordPress, Vercel and Cloudflare, narrower than Profound's connector ecosystem.

When each one wins
When Sitebulb wins
- Budget is the constraint. Sitebulb starts at $18/mo vs Writesonic GEO's $79/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.

- 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.

Switching from one to the other
From Sitebulb to Writesonic GEO
Export your saved queries and prompt panels from Sitebulb (most tools support CSV export). Most Writesonic GEO setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Writesonic GEO's data againstSitebulb's; one to two weeks of full reconciliation before you cancel Sitebulb. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From Writesonic GEO to Sitebulb
Same flow in reverse. Export from Writesonic GEO, import to Sitebulb. 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 Sitebulb and Writesonic GEOare 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, Sitebulb or Writesonic GEO?
Honestly: neither one fully solves the problem. Sitebulb and Writesonic GEO 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 Sitebulb and Writesonic GEO cost?
Sitebulb starts at $18/mo. Writesonic GEO starts at $79/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.
Which AI platforms do Sitebulb and Writesonic GEO cover?
Sitebulb covers an undisclosed number of AI platforms. Writesonic GEO covers 4. Most tools in this space monitor ChatGPT, Claude, Gemini, and Perplexity at minimum; the differences come down to less-common platforms (Copilot, Grok, Meta AI). GrowthManager.ai monitors the same four primary platforms and acts on the data.
Do Sitebulb and Writesonic GEO actually improve your AI visibility, or just measure it?
Both Sitebulb and Writesonic GEO 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 Sitebulb and Writesonic GEO?
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.
