Pick
Siteimprove
Pick Siteimprove if you need broader AI platform coverage (5 platforms vs 0); and you want the better-funded company (Acquired by Nordic Capital in 2020 (~€500M)); and SOC 2 Type 2 matters for your security review.
Head-to-head review · Updated June 2026
Siteimprove vs Topic: which one wins in 2026?
Siteimprove and Topic 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. Siteimprove is the more-funded incumbent; Topic is the leaner challenger.
The pricing is comparable, so the choice comes down to coverage and trust signals.
The verdict
Pick
Topic
Topic is the right pick if your team prefers their approach and pricing fits.
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 Siteimprove
Siteimprove has raised Acquired by Nordic Capital in 2020 (~€500M) (Nordic Capital majority acquisition 2020). Founded by Morten Ebbesen, based in Copenhagen, Denmark. On their site they list 10 named customers including Google, Microsoft, Amazon, IBM. They cover 5 AI platforms. Pricing starts at Custom quote.
Digital experience optimization with SEO, accessibility, and content quality.
What people praise
- Recognized as a G2 Leader in Digital Accessibility for six consecutive years, the longest streak in the category.
- Modular suite (Accessibility, SEO, QA, Analytics, Policy, Content) lets enterprises pick exactly the modules they need.
- Native WCAG 2.2 AA validation with in-code highlights and remediation tips, plus European Accessibility Act readiness.
- New agentic content intelligence platform launches Accessibility, Analytics, SEO/AEO, and Content Strategy AI agents.
Where it falls short
- Steep learning curve flagged in many G2 reviews; configuration is notably harder than simpler accessibility checkers.
- No public pricing; published Vendr benchmarks show $12K-$70K+/year, putting it out of reach for SMBs.
- Automated testing cannot detect all accessibility issues, so manual audits remain necessary for legal compliance.
- Limited Joomla integration and unoptimized PDF exports are recurring complaints in reviewer feedback.
The case for Topic
Founded by Ryo Chiba, Nikhil Aitharaju, based in Toronto, Canada. On their site they list 9 named customers including Magoosh, Quizlet, BiggerPockets, Amerisleep. Pricing starts at $99/mo.
Content optimization platform that turns research into briefs and outlines.
What people praise
- Cuts content research time 45-50% by auto-parsing the top 30 Google results for headings, questions, and keyword targets.
- Simple Starter at $99/mo and $7 intro pack make it the cheapest serious entry point versus Surfer, Clearscope, and MarketMuse.
- Magoosh case study shows 300%+ year-over-year new-user growth on a single optimized post.
- Used by BiggerPockets, Magoosh, Quizlet, Amerisleep, Elementor, TrustRadius, and WSI.
Where it falls short
- Brief and optimization quotas (10 to 50 per month) are tight for agencies running multiple clients.
- No native AI article generator at the level of Surfer AI or Frase Pro; Topic positions as briefs, not full drafts.
- Pricing changes infrequent and no free trial beyond the $7 intro pack.
- Acquired by CafeMedia/Raptive in September 2021; roadmap pace has slowed compared to standalone Surfer or Clearscope.

When each one wins
When Siteimprove wins
- Platform coverage matters. Siteimprove monitors 5 AI platforms; Topic covers 0.
- You want the better-funded incumbent. Siteimprove has raised Acquired by Nordic Capital in 2020 (~€500M), giving it more runway and shipping velocity.
- Procurement requires SOC 2 Type 2. Siteimprove has it; Topic doesn't yet.
When Topic wins
- Budget is the constraint. Topic starts at $99/mo vs Siteimprove's $∞/mo, so on a per-seat basis it's the cheaper way in.
- Cuts content research time 45-50% by auto-parsing the top 30 Google results for headings, questions, and keyword targets.
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 Siteimprove 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 Siteimprove over Topic
- Broader AI platform coverage. Siteimprove tracks visibility across 5 AI engines vs Topic's 0.
- Better-funded incumbent. Siteimprove has raised Acquired by Nordic Capital in 2020 (~€500M), giving it more runway and shipping velocity than Topic.
- SOC 2 Type 2. Siteimprove carries SOC 2 Type 2; Topic does not yet, which can hold up procurement.
- More mature platform. Siteimprove (founded 2003) has had more time to harden the product than Topic (2019).
- Wider integration ecosystem. Siteimprove integrates with 7 tools; Topic ships 3.
- What users praise most. Recognized as a G2 Leader in Digital Accessibility for six consecutive years, the longest streak in the category.
- EU data residency. Siteimprove is HQ'd in Copenhagen, Denmark, which simplifies GDPR data-processor agreements for European buyers.
Reasons to pick Topic over Siteimprove
- Lower entry price. Topic publishes a clear entry tier at $99/mo; Siteimprove gates pricing.
- More plan flexibility. Topic offers 4 pricing tiers vs Siteimprove's 3, so there's a better chance one fits your team size.
- Built for the LLM era. Topic was founded in 2019, built around AI search from day one; Siteimprove dates back to 2003 and is retrofitting.
- What users praise most. Cuts content research time 45-50% by auto-parsing the top 30 Google results for headings, questions, and keyword targets.
Switching from one to the other
From Siteimprove to Topic
Export your saved queries and prompt panels from Siteimprove (most tools support CSV export). Most Topic setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Topic's data againstSiteimprove's; one to two weeks of full reconciliation before you cancel Siteimprove. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From Topic to Siteimprove
Same flow in reverse. Export from Topic, import to Siteimprove. 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 Siteimprove and Topicare 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, Siteimprove or Topic?
Honestly: neither one fully solves the problem. Siteimprove and Topic 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 Siteimprove 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 Siteimprove and Topic cost?
Siteimprove starts at Custom quote. Topic starts at $99/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 Siteimprove and Topic cover?
Siteimprove covers 5 AI platforms. Topic covers an undisclosed number of. 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 Siteimprove and Topic actually improve your AI visibility, or just measure it?
Both Siteimprove and Topic 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 Siteimprove and Topic?
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.
