Head-to-head review · Updated June 2026

Linkup vs Page Optimizer Pro: which one wins in 2026?

Linkup and Page Optimizer Pro 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. Linkup has raised $13.2M, Page Optimizer Pro has raised Bootstrapped; Linkup is the more-funded incumbent; Page Optimizer Pro is the leaner challenger.

Linkup 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
★ Our pick
Pick

Linkup

Pick Linkup if you want the cheaper option ($0/mo vs $40/mo); and you trust traction signals — they list 8 customers, Page Optimizer Pro lists 0; and you want the better-funded company ($13.2M); and SOC 2 Type 2 matters for your security review.

Pick

Page Optimizer Pro

Pick Page Optimizer Pro if you want the cheaper option ($40/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.

The case for Linkup

Linkup has raised $13.2M ($10M Seed (Feb 2026, led by Gradient)). Founded by Philippe Mizrahi, Denis Charrier, Boris Toledano, based in Paris, France. On their site they list 8 named customers including McKinsey & Company, Cohere, KPMG, EY. Pricing starts at $0/mo.

Search API used by AI agents — the data layer for retrieval-augmented LLM apps.

What people praise

  • Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product
  • Licenses content from publishers and pays them on usage, so results are legal and citation-safe
  • Sub-second search latency is fast enough for real-time agent tool calls
  • Free tier ships 4,000 queries and startups can apply for $5,000 in credits

Where it falls short

  • Per-request pricing makes monthly cost hard to forecast for high-volume agents
  • Deep Research mode can cost up to $2.50 per call, expensive at scale
  • Not a visibility, SEO or content product, it is a raw search API and you build the workflow yourself
  • No G2 or Capterra reviews yet, the company only launched its API in late 2024

The case for Page Optimizer Pro

Page Optimizer Pro has raised Bootstrapped. Founded by Kyle Roof, based in London, UK. Pricing starts at $40/mo.

On-page SEO optimization with data-driven recommendations.

What people praise

  • Recommendations are grounded in Kyle Roof's 400+ scientific SEO tests and a granted Google ranking-factor patent, which gives users more confidence than competitor tools that rely on correlation alone.
  • Reviewers consistently report pages moving to positions 1-3 within days of applying the on-page edits the tool recommends.
  • POP Watchdog is the only tool in the category that alerts you when a ranking drops and tells you exactly what changed on the page or in the SERP.
  • Credits can be bought one-off without committing to a monthly subscription, which makes it accessible for freelancers running occasional audits.

Where it falls short

  • Credit system is opaque and burns through fast , users want a flat unlimited tier without the per-report accounting.
  • Interface has a steep learning curve and reviewers describe it as less intuitive than Surfer or Frase, with key features hidden under multiple clicks.
  • AI Writer outputs large blocks of unstructured text that need heavy editing before publishing.
  • Integrations are thin compared to Semrush or Moz , no native CMS publishing, no Search Console import.

When each one wins

When Linkup wins
  • Budget is the constraint. Linkup starts at $0/mo vs Page Optimizer Pro's $40/mo, so on a per-seat basis it's the cheaper way in.
  • You're enterprise and need to call a reference. Linkup lists 8 named customers; Page Optimizer Pro lists 0.
  • You want the better-funded incumbent. Linkup has raised $13.2M, giving it more runway and shipping velocity.
  • Procurement requires SOC 2 Type 2. Linkup has it; Page Optimizer Pro doesn't yet.
When Page Optimizer Pro wins
  • Recommendations are grounded in Kyle Roof's 400+ scientific SEO tests and a granted Google ranking-factor patent, which gives users more confidence than competitor tools that rely on correlation alone.
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 Linkup 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 Linkup over Page Optimizer Pro

  4. SOC 2 Type 2. Linkup carries SOC 2 Type 2; Page Optimizer Pro does not yet, which can hold up procurement.
  5. Built for the LLM era. Linkup was founded in 2024, built around AI search from day one; Page Optimizer Pro dates back to 2017 and is retrofitting.
  6. Wider integration ecosystem. Linkup integrates with 7 tools; Page Optimizer Pro ships 3.
  7. What users praise most. Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product

  2. More mature platform. Page Optimizer Pro (founded 2017) has had more time to harden the product than Linkup (2024).

Switching from one to the other

From Linkup to Page Optimizer Pro

Export your saved queries and prompt panels from Linkup (most tools support CSV export). Most Page Optimizer Pro setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Page Optimizer Pro's data againstLinkup's; one to two weeks of full reconciliation before you cancel Linkup. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.

From Page Optimizer Pro to Linkup

Same flow in reverse. Export from Page Optimizer Pro, import to Linkup. 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 Linkup and Page Optimizer Proare 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, Linkup or Page Optimizer Pro?

Honestly: neither one fully solves the problem. Linkup and Page Optimizer Pro 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 Linkup 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 Linkup and Page Optimizer Pro cost?

Linkup starts at $0/mo. Page Optimizer Pro starts at $40/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 Linkup and Page Optimizer Pro actually improve your AI visibility, or just measure it?

Both Linkup and Page Optimizer Pro 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 Linkup and Page Optimizer Pro?

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.
