ContentKing vs Oncrawl in 2026: always-on crawl monitoring vs a crawl-plus-log-plus-API platform
Both are enterprise, demo-gated products with no public pricing. One monitors continuously and alerts by business impact. The other pairs crawl data with log analysis, AI answer-citation tracking, and a REST API built for BI pipelines.
ContentKing
Oncrawl- ContentKing crawls continuously and alerts on detected changes; Oncrawl runs scheduled crawls paired with server log analysis showing exactly which URLs bots visit and how often.
- Oncrawl includes AI-generated answer visibility monitoring, tracking whether content is cited in AI responses. ContentKing's AI coverage stops at AI crawler log access (GPTBot, ClaudeBot, PerplexityBot), not citation tracking.
- Both require a sales conversation with no published pricing for any tier.
- Oncrawl's REST API integrates with Looker Studio, BigQuery, and Tableau. ContentKing offers a Data API and MCP server, both restricted to its Enterprise tier.
- ContentKing keeps 60 months of snapshot history. Oncrawl's single Enterprise tier does not publish a specific retention figure.
- Neither tool offers a self-serve free tier; ContentKing offers a free trial on Essentials under 100,000 pages, while Oncrawl has no public trial listed at all.
ContentKing and Oncrawl both target enterprise technical SEO teams and both require a sales call before you see a price, but the products solve different problems. ContentKing, sold as Conductor Monitoring since Conductor's acquisition, crawls a site continuously and turns every detected change into a business-impact-ranked alert. Oncrawl combines crawl data with server log analysis and now includes AI-generated answer visibility monitoring, tracking whether a brand's content is actually cited in AI responses, alongside a REST API built to feed Looker Studio, BigQuery, or Tableau. ContentKing is closer to an always-on alarm system; Oncrawl is closer to a measurement and reporting layer for teams that already know what they are looking for and want the data piped into their own infrastructure.
The tools at a glance
ContentKing
24/7 website monitoring that catches AEO and SEO technical issues before they cost you traffic
ContentKing is a continuous monitoring platform, sold today as Conductor Monitoring following Conductor's acquisition of the product. Instead of a scheduled crawl, it watches the site around the clock and flags a broken redirect, a stripped canonical, or a Core Web Vitals regression the moment it is detected, routing the alert to the right person or channel based on issue type and severity.
Every issue is ranked by business impact, so teams work the highest-traffic problem first, and 60 months of snapshot history supports root-cause diagnosis and compliance work well beyond what most competing tools retain. At Enterprise tier, log file analysis extends to AI crawler traffic from GPTBot, ClaudeBot, and PerplexityBot, showing whether AI systems can reach a page, though it stops short of tracking whether the brand is actually cited in an AI-generated answer the way Oncrawl does.
ContentKing does not publish pricing for any of its three tiers, and the AI crawler log analysis specifically requires Enterprise. Within Conductor, Monitoring connects to Intelligence and Creator products so technical issues link to keyword and content data, but the platform remains scoped to monitoring and alerting rather than the crawl-plus-log-plus-API data layer Oncrawl builds toward.

Oncrawl
Cloud-based technical SEO platform combining crawl data, log analysis, and AI bot tracking.
Oncrawl is a cloud technical SEO platform built around three data sources: crawl data, server log data, and performance data. Most crawlers describe what is on a site; Oncrawl adds what search engines and AI crawlers are actually visiting and how often, which is a different and complementary question that log analysis, built into the core product rather than sold as an add-on, is designed to answer.
Oncrawl has kept pace with the shift toward AI search on two fronts: it tracks AI bot crawl activity from GPTBot, ClaudeBot, and PerplexityBot at the URL level, and it includes AI-generated answer visibility monitoring, which tracks whether a brand's content is actually being cited in AI responses. That second piece is a genuine citation-tracking capability, not just a crawl-access log, and it sits alongside scheduled crawls, redirect and canonical checks, and automated regression alerts.
The REST API is one of Oncrawl's clearest strengths: it exposes crawl, log, and performance data in a structured format that integrates with Looker Studio, BigQuery, and Tableau, so teams with existing data infrastructure can treat Oncrawl as a data source rather than a required interface. Pricing sits behind a single custom Enterprise tier with no self-serve option, and the platform requires real configuration to get value from, which teams without dedicated technical SEO staff may not fully use.

Considering AI Peekaboo alongside ContentKing and Oncrawl?
Oncrawl includes genuine AI-generated answer visibility monitoring, tracking whether content is cited in AI responses, but it sits inside a single Enterprise tier with no public pricing and a demo-first sales process, and ContentKing does not track AI citations at all, only AI crawler access on its top tier. AI Peekaboo is a dedicated AI visibility platform with a read and write API and white-label reporting available on every plan, built for teams that want AI citation tracking without an enterprise sales cycle just to see a price.

ContentKingOncrawlOncrawlContentKingOncrawlContentKingNeither tool discloses pricing, so the decision comes down to what each one is actually measuring. ContentKing is an alerting system: it watches the whole site continuously and turns changes into ranked alerts, which is the right shape for a team whose failure mode is not finding out about a break fast enough. Oncrawl is a data platform: crawl plus log plus, increasingly, AI citation visibility, exposed through a REST API built to feed a team's own reporting stack rather than to be the only interface they use. A team that wants an alarm should lean ContentKing; a team that wants raw, structured technical and AI-visibility data to build their own dashboards on should lean Oncrawl.
Bottom line
Choose ContentKing if same-day detection of technical breakage on a large site is the priority and you want alerts ranked by business impact out of the box. Choose Oncrawl if you need server log analysis, AI citation visibility, and a REST API that plugs into an existing BI stack, and you are comfortable configuring the platform yourself. Teams evaluating both should ask each vendor directly what AI visibility reporting actually includes during the sales process, since Oncrawl's citation tracking and ContentKing's crawler-access logging measure genuinely different things despite both being labeled "AI" features.
Frequently asked questions
Does Oncrawl actually track AI citations, or just AI crawler access like ContentKing?
Oncrawl tracks both: it logs AI bot crawl activity from GPTBot, ClaudeBot, and PerplexityBot at the URL level, and separately includes AI-generated answer visibility monitoring that tracks whether content is actually cited in AI responses. ContentKing's AI feature only covers the first part, crawler access logging on its Enterprise tier, and does not track whether a brand appears in AI-generated answers.
Why do neither ContentKing nor Oncrawl publish pricing?
Both are sold through a demo-first enterprise sales process, ContentKing via Conductor and Oncrawl as its own standalone Enterprise-only tier, and both companies negotiate pricing based on site size and configuration rather than listing it publicly. Neither offers a self-serve monthly plan with a fixed price.
Is Oncrawl's REST API better suited to teams with an existing data pipeline than ContentKing's API?
Yes, Oncrawl's REST API is specifically built to integrate with Looker Studio, BigQuery, and Tableau, so it functions well as a data source for teams that already have reporting infrastructure. ContentKing's Data API and MCP server exist for similar developer integration purposes but are restricted to the Enterprise tier and are less explicitly positioned around BI tool integration.
Which tool has stronger server log analysis, ContentKing or Oncrawl?
Oncrawl has the stronger log analysis capability of the two: it is a core part of the platform, not an add-on, and it maps exactly which URLs search engines and AI crawlers visit and how crawl budget is allocated. ContentKing restricts log file analysis, including AI crawler traffic, to its Enterprise tier only, so it is not available at all on Essentials or Growth.
Does either tool offer a free trial for evaluation before a sales call?
ContentKing offers a free trial on its Essentials tier for sites under 100,000 pages, giving smaller-scale teams a way to test the product before a sales conversation. Oncrawl does not list a public free trial or self-serve option anywhere in its materials; access requires a demo and custom pricing discussion from the start.
Is Oncrawl worth the configuration effort compared to a simpler monitoring tool?
It depends on whether log analysis and AI citation tracking are actual requirements, since Oncrawl requires meaningful setup and is described as needing dedicated technical SEO staff to get full value from it. Teams that only need continuous alerting on technical breakage, without log analysis or a BI-ready API, will likely get more immediate value from ContentKing's more focused monitoring workflow.
