ContentKing vs Treo in 2026: sales-gated site monitoring vs a free-tier Core Web Vitals tracker
ContentKing watches your whole technical site continuously and won't tell you what it costs. Treo tracks Core Web Vitals using real Chrome UX Report data, starts at $0, and gets expensive fast once you pass the free tier.
ContentKing
Treo- Treo has a free tier for one site with no cost. ContentKing publishes no pricing on any of its three tiers and requires a sales conversation.
- ContentKing monitors full technical SEO health continuously: redirects, canonicals, meta tags, and more. Treo is narrower by design, tracking only Core Web Vitals and Lighthouse performance data.
- Treo pulls real Chrome UX Report field data covering how actual Chrome users experienced a page over the past 28 days, alongside on-demand Lighthouse lab scores in the same dashboard.
- Treo requires no script installation; it discovers URLs automatically via sitemap scanning. ContentKing similarly needs no script for its core crawl-based monitoring.
- ContentKing tracks AI crawlers like GPTBot and ClaudeBot through Enterprise-only log file analysis. Treo has no AI crawler or AI search tracking of any kind.
- Treo's pricing jumps from Free to $75/month for Vital, then scales to $375/month for Scale before Enterprise. ContentKing has no visible price points anywhere in its tier structure.
- Both offer competitive benchmarking, but for different metrics: Treo benchmarks Core Web Vitals against competitor domains, while ContentKing has no competitive tracking feature at all.
ContentKing and Treo both get filed under technical SEO monitoring, but they're built for different jobs. ContentKing, now Conductor Monitoring after Conductor's acquisition, is a full-surface technical health monitor: redirects, canonicals, meta tags, and Core Web Vitals, crawled continuously, with AI crawler log analysis on its top tier. Treo does one thing: it pulls real-world Core Web Vitals data from the Chrome UX Report and pairs it with on-demand Lighthouse lab scores, discovering URLs automatically through sitemap scanning rather than requiring any script installation. Treo has a genuine free tier for a single site; ContentKing has no public price at all. Neither tracks AI citations, though ContentKing at least monitors whether AI crawlers can reach your pages, which Treo doesn't attempt.
The tools at a glance
ContentKing
24/7 website monitoring that catches AEO and SEO technical issues before they cost you traffic
ContentKing crawls a site continuously rather than on a schedule, covering the full range of technical SEO signals: canonicals, redirects, meta tags, indexability, and Core Web Vitals on the Growth and Enterprise tiers. Since Conductor's acquisition, it operates as Conductor Monitoring, the technical health layer inside a broader AEO and SEO platform, and issues are flagged within hours of occurring rather than at the next scheduled crawl.
Detected issues are ranked by business impact, weighting the traffic value of affected pages so the highest-ROI fixes surface first, and 60 months of snapshot history supports root-cause diagnosis on sites where problems compound quickly. Enterprise-tier log file analysis extends into AI crawler visibility, tracking GPTBot and ClaudeBot access, which is more than Treo attempts.
What ContentKing does not offer is a way to see the product without talking to sales. Essentials, Growth, and Enterprise all show "Contact for pricing," with a free trial available only on Essentials for sites under 100,000 pages. There is no free tier comparable to Treo's, and Core Web Vitals here is one signal among many rather than the dedicated focus of the product.
| Feature | Essentials Contact for pricing | Growth Contact for pricing | Enterprise Contact for pricing |
|---|---|---|---|
| Pages monitored 24/7 | Up to 100,000 | Up to 500,000 | Custom |
| Core Web Vitals | No | Yes | Yes |
| Log file analysis (AI crawlers) | No | No | Yes |
| Data API | No | No | Yes |
Treo
Core Web Vitals monitoring using real-world Chrome UX Report data.
Treo is built around one job: making Core Web Vitals data accessible without forcing teams to build their own Chrome UX Report (CrUX) API integration. It surfaces real field data showing how actual Chrome users experienced a page over the past 28 days, alongside on-demand Lighthouse lab scores, so you can tell the difference between "our lab score improved" and "users are actually loading faster."
URL discovery happens automatically via sitemap scanning, with no script installation and no cookies or client-side tracking required. Competitive benchmarking lets you track Core Web Vitals against competitor domains using the same CrUX data source, and a multi-site dashboard lets agencies monitor performance across hundreds of client domains from a single view.
The limitation is scope and price scaling. Treo does nothing outside performance monitoring, so it won't catch a broken redirect or a dropped canonical the way ContentKing does, and CrUX only covers URLs with enough real-user traffic, so new or low-traffic pages may show no field data at all. Pricing starts free for one site but jumps to $75/month for Vital, then climbs to $375/month for Scale before Enterprise, a steep curve for what is fundamentally a monitoring layer on public Google data.
| Feature | Free $0/month | Vital $75/month | Pro $185/month | Scale $375/month | Enterprise Contact for pricing |
|---|---|---|---|---|---|
| Sites monitored | 1 | Up to 5 | Up to 15 | Up to 50 | Custom |
| CrUX field data | Yes | Yes | Yes | Yes | Yes |
| Competitive benchmarking | No | Yes | Yes | Yes | Yes |
| API access | No | Yes | Yes | Yes | Yes |

Which should you choose?
ContentKingTreoTreoContentKingContentKingTreoTreoThe honest framing here is accessibility versus breadth. Treo gets you real CrUX-backed Core Web Vitals data for free on one site, with no script to install and no sales call required, but it does nothing outside performance: no redirect checks, no canonical monitoring, no AI crawler visibility. ContentKing covers all of that and monitors continuously rather than on a schedule, but you cannot find out what it costs without a sales conversation, and its Core Web Vitals tracking is a feature inside a bigger product rather than the point of the product. If Core Web Vitals is your actual problem, Treo solves it more directly and more cheaply. If Core Web Vitals is one symptom of a broader technical health problem, ContentKing is built for that, at whatever price sales quotes you.
Bottom line
Start with Treo's free tier if Core Web Vitals and page speed are your specific concern; it gets you real Chrome UX Report data with zero setup cost, and the Vital plan at $75/month is still cheaper than most enterprise technical SEO tools. Book the ContentKing demo if your site needs full technical monitoring, redirects, canonicals, meta tags, and AI crawler access, watched continuously rather than as a periodic check. Running Treo for performance and a separate crawler for broader technical health is a reasonable middle path if ContentKing's pricing process is more than your team wants to take on.
Frequently asked questions
Is Treo a good enough substitute for ContentKing if I only care about page speed?
Treo is a stronger fit if page speed and Core Web Vitals are the specific problem, since it pulls real Chrome UX Report field data alongside Lighthouse lab scores and starts free for a single site. ContentKing includes Core Web Vitals only on its Growth and Enterprise tiers as one signal among many, so you would be paying enterprise, sales-gated pricing for a feature Treo offers at no cost.
Does ContentKing use real Chrome UX Report data the way Treo does?
ContentKing's published feature list does not describe its Core Web Vitals tracking as CrUX-based field data the way Treo's is; it appears as a standard monitored metric on Growth and Enterprise tiers rather than a dedicated real-user data product. Treo is built specifically around CrUX field data paired with on-demand Lighthouse scores, which is its entire reason to exist.
How much does Treo cost compared to ContentKing?
Treo starts free for one site, then jumps to $75 a month for Vital, $185 for Pro, and $375 for Scale before Enterprise pricing kicks in. ContentKing discloses no pricing at all on any of its three tiers, Essentials, Growth, or Enterprise, so there is no public number to compare against.
Can Treo catch a broken redirect or a missing canonical tag the way ContentKing can?
Treo cannot catch broken redirects, canonical issues, or meta tag changes; it is scoped entirely to Core Web Vitals and Lighthouse performance data. ContentKing is built for exactly this kind of full-site technical monitoring, which is the core reason to choose it over a performance-only tool like Treo.
Does either Treo or ContentKing track AI crawlers like GPTBot?
ContentKing tracks AI crawler activity through log file analysis, but only on its Enterprise tier, showing how often GPTBot, ClaudeBot, and similar bots visit and whether they hit errors. Treo has no AI crawler tracking or AI search visibility feature at all; it stays entirely within Core Web Vitals and Lighthouse performance monitoring.
Which tool is better for an agency managing Core Web Vitals across many client sites?
Treo is purpose-built for this with its multi-site dashboard, supporting up to 50 sites on the Scale plan and custom limits on Enterprise, plus competitive benchmarking against competitor domains using the same CrUX data source. ContentKing scales by pages monitored rather than sites, and its pricing opacity makes it harder to plan a multi-client performance monitoring budget in advance.
