PageOptimizer Pro vs Seobility in 2026: Research-backed on-page depth vs a genuinely free all-in-one suite
One tool goes deep on a single discipline with 400+ peer-reviewed experiments behind it. The other covers technical audits, rank tracking, and backlinks for free before you pay a cent.
PageOptimizer Pro
Seobility- PageOptimizer Pro grounds its recommendations in 400+ peer-reviewed SEO experiments rather than correlation data. Seobility does not offer a comparable on-page scoring engine.
- Seobility has a genuinely usable free plan: 1,000 crawled subpages and 10 tracked keywords, indefinitely. PageOptimizer Pro has no free tier at all.
- Neither tool tracks AI search visibility in ChatGPT, Gemini, or Perplexity as of mid-2026.
- PageOptimizer Pro's EEAT audit checks 100+ trust and authority signals, more thorough than the general page-quality checks in Seobility's crawler.
- Seobility includes rank tracking and backlink monitoring out of the box. PageOptimizer Pro has neither; it assumes you already have a rank tracker elsewhere.
- White-label reporting exists on both tools' top plans: PageOptimizer Pro at $275/month (White Glove), Seobility at €179.90/month (Agency).
PageOptimizer Pro and Seobility rarely compete for the same buyer, which is exactly why the comparison is useful. PageOptimizer Pro is a specialist: its Rank Engine scores 300+ on-page parameters against a keyword, and its EEAT audit checks 100+ trust signals, all grounded in controlled experiments rather than correlation studies. Seobility is a generalist with a real free plan: one project, 1,000 crawled subpages, and 10 tracked keywords at no cost, then a Premium tier under €50/month that expands those limits. If your bottleneck is getting individual pages to rank, PageOptimizer Pro gives you a defensible methodology. If your bottleneck is not having a working SEO toolkit at all, Seobility gets you a functioning technical audit and rank tracker before you spend anything.
The tools at a glance
PageOptimizer Pro
On-page SEO optimization grounded in 400+ peer-reviewed experiments, built for Google and LLM visibility.
PageOptimizer Pro is built around the Rank Engine, which scores a page against 300+ on-page parameters for a target keyword and tells you which specific signals to change. The methodology comes from controlled experiments run by founder Kyle Roof's team, so the rationale behind each recommendation is clearer than tools that just report what correlates with high rankings across a sample of pages.
Beyond the core scoring, POP includes a 100+ signal EEAT audit, a schema generator covering 70+ types, and SEO prompts built specifically for on-page tasks like titles, meta descriptions, and section rewrites. There is no rank tracker, no backlink index, and no site-wide crawler here; POP assumes those tools already exist in your stack and focuses entirely on making individual pages rank better once you know what to target.
The cost of that focus is accessibility. There is no free tier, and API access is locked to the Teams plan and above at $143/month. For a solo SEO or small in-house team evaluating tools on a budget, that is a real barrier before you ever see the Rank Engine work.
| Feature | Basic $40/month | Unlimited $72/month | Teams $143/month | White Glove $275/month |
|---|---|---|---|---|
| Page analyses | 15/month | Unlimited | Unlimited | Unlimited |
| EEAT audit | No | Yes | Yes | Yes |
| Schema markup builder | Yes | Yes | Yes | Yes |
| White-label reports | No | No | No | Yes |
| API access | No | No | Yes | Yes |
Seobility
Affordable all-in-one SEO suite with a free tier, technical audits, rank tracking, and white-label reporting
Seobility packages technical site auditing, keyword rank tracking, backlink monitoring, and competitor analysis into a single subscription, and the free Basic plan is a real working product rather than a teaser: one project, up to 1,000 crawled subpages, 10 tracked keywords, and 100 monitored backlinks, with no time limit or credit card requirement.
The crawler flags issues across five categories (meta data, page quality, structure, links, and server config) with plain-language explanations that work for clients who are not SEO specialists. Daily rank tracking covers Google and Bing with SERP feature detection, and the Agency plan at €179.90/month adds white-label PDF reports across up to 10 client projects.
What Seobility does not do is on-page optimization at the depth of a specialist tool. There is no equivalent to a 300-parameter scoring engine or a dedicated EEAT checklist, and there is no API on any plan, so custom dashboards or BI integrations are off the table entirely.
| Feature | Basic (Free) Free | Premium €49.90/month | Agency €179.90/month |
|---|---|---|---|
| Subpages crawled | 1,000 | 25,000 | 25,000 |
| Keywords tracked | 10 | 1,000 | 10,000 |
| Backlinks monitored | 100 | Unlimited | Unlimited |
| White-label reports | No | No | Yes |
| API access | No | No | No |

Neither tool tracks AI search visibility
PageOptimizer Pro and Seobility both stop at traditional Google optimization: POP sharpens on-page signals and EEAT, Seobility handles crawling and rank tracking, but neither monitors whether your brand actually shows up in ChatGPT, Gemini, or Perplexity answers. AI Peekaboo fills that specific gap with AI visibility tracking, a read/write API on every plan from $50 per month, and white-label reporting, making it a natural third tool alongside either platform rather than a replacement for what they already do well.

PageOptimizer ProSeobilityPageOptimizer ProSeobilityPageOptimizer ProSeobilityThese tools solve different problems and rarely get shortlisted against each other by the same buyer. PageOptimizer Pro assumes you already have keyword and rank data and focuses entirely on making a given page rank better. Seobility assumes you need the whole workflow, audits, tracking, and backlinks, and would rather give you a working free version of all of it than a deep specialist tool for one piece.
Bottom line
Pick PageOptimizer Pro if on-page execution is your actual bottleneck and you want a scoring methodology you can explain to a client. Pick Seobility if you need a working SEO toolkit today and do not have budget for one yet; the free plan is not a trial, it is a real product. Larger agencies running both content optimization and client reporting at scale often end up needing both, since neither covers the other's core job.
Frequently asked questions
Is PageOptimizer Pro worth it if I already use Seobility for rank tracking?
Yes, the two tools overlap very little. Seobility handles crawling, tracking, and backlink monitoring, while PageOptimizer Pro adds a research-backed on-page scoring engine and EEAT audit that Seobility does not offer. Many teams run both rather than choosing one over the other.
Does Seobility's free plan actually replace a paid SEO tool?
For a single small site, yes, within its limits: 1,000 crawled subpages, 10 tracked keywords, and 100 monitored backlinks, with no expiry date. It will not replace a paid tool once you manage multiple client sites or need more than 10 keywords tracked, but as a starting point it is a real working product.
Which tool is better for AI search visibility in 2026?
Neither. PageOptimizer Pro focuses its "LLM visibility" language on EEAT and schema signals that help AI models trust your content, not on monitoring whether you actually appear in AI answers. Seobility does not track AI search at all. Teams that need that specific measurement should add a dedicated AI visibility tool alongside either platform.
Does PageOptimizer Pro have an API on its entry-level plan?
No. API access starts on the Teams plan at $143 per month. The Basic plan at $40 per month and the Unlimited plan at $72 per month do not include API access, so budget for Teams if programmatic access matters to your workflow.
Can Seobility deliver white-label reports for agency clients?
Yes, but only on the Agency plan at €179.90 per month, which covers up to 10 client projects. The free and Premium tiers show Seobility branding on all reports and exports.
