ContentKing vs Sitechecker in 2026: enterprise-only continuous monitoring vs self-serve crawler with an AI Visibility Tracker
ContentKing (now Conductor Monitoring) runs 24/7 crawling with 60 months of history, sold only through a sales conversation. Sitechecker is a self-serve crawler and rank tracker starting at $89/month with an AI Visibility Tracker built for agencies.
ContentKing
Sitechecker- ContentKing crawls continuously and keeps 60 months of site-state history. Sitechecker runs on a scheduled crawl and rank-tracking cadence with no documented history retention window.
- Sitechecker publishes pricing starting at $89/month. ContentKing has no public pricing across any of its three tiers and requires a sales conversation to see a number.
- ContentKing's AI feature is log file analysis of crawler traffic from GPTBot, ClaudeBot, and PerplexityBot, gated to Enterprise. Sitechecker's AI Visibility Tracker checks whether ChatGPT and Perplexity actually cite the brand in generated answers, unlocked from Standard tier. These measure different things.
- Sitechecker includes white-label reports from its $219/month Standard tier. ContentKing does not list white-label reporting as a feature on any tier.
- Both tools gate API access to their top tier only: ContentKing's Data API is Enterprise-only, and Sitechecker's API is reserved for its Enterprise plan as well.
- ContentKing offers a free trial on Essentials for sites under 100,000 pages. Sitechecker has no permanent free tier, and trial access is not guaranteed, only available on request.
- ContentKing ships an MCP server for developer workflows alongside its Data API. Sitechecker has no equivalent developer integration layer documented.
ContentKing and Sitechecker both get filed under "technical SEO monitoring," but they solve different problems for different budgets. ContentKing, absorbed into Conductor as Conductor Monitoring after the acquisition, crawls a site continuously rather than on a schedule and keeps five years of snapshot history for root-cause diagnosis, with an Enterprise-only log file analysis feature that shows whether GPTBot and ClaudeBot can actually reach your pages. None of it has a published price. Sitechecker is a lighter, self-serve bundle: a crawler, a rank tracker, and an AI Visibility Tracker that checks whether ChatGPT and Perplexity are citing your brand, starting at $89/month with white-label reports available from its Standard tier. One tool tells you whether AI crawlers can access your content; the other tells you whether AI models are actually citing it. That distinction matters more than the surface-level "both monitor SEO health" framing suggests.
The tools at a glance
ContentKing
24/7 website monitoring that catches AEO and SEO technical issues before they cost you traffic
ContentKing started as a standalone real-time SEO monitoring tool and has since been folded into the Conductor platform as Conductor Monitoring, following Conductor's acquisition. The core mechanic hasn't changed: the site is crawled around the clock instead of on a weekly schedule, so a broken redirect, a dropped canonical, or a Core Web Vitals regression gets flagged within hours rather than at the next scheduled audit. Alerts route by issue type and severity so a broken redirect doesn't also land in the content team's inbox.
The feature that separates ContentKing from a standard crawler is log file analysis, now extended to cover AI crawler traffic from GPTBot, ClaudeBot, and PerplexityBot. It tells you how often each crawler visits, which pages it skips, and whether it hits errors, which is a genuinely different signal from citation tracking: it answers "can the AI reach my content" rather than "is the AI citing my content." That feature, along with 60 months of snapshot history for compliance and root-cause work, is locked to the Enterprise tier.
The trade-off is that none of this has a public price. Essentials, Growth, and Enterprise all show "Contact for pricing," and there's no way to see a number without a sales call, though Essentials does offer a free trial for sites under 100,000 pages. For a large organization already running Adobe or Conductor tooling with a procurement process built for sales-led vendors, that's a non-issue. For a smaller team that wants to compare costs before picking up the phone, it's a real barrier.

Sitechecker
SEO command center for agencies managing multiple client sites, with crawling, rank tracking, technical issue detection, and AI visibility tracking
Sitechecker bundles a website crawler, a keyword rank tracker, and change-detection alerts into one dashboard aimed at agencies and in-house SMB teams who don't need enterprise-scale crawl infrastructure. The crawler flags broken links, missing meta tags, duplicate content, and redirect chains, sorted by severity, while the rank tracker follows keyword positions with scheduled updates and generates client-facing trend reports.
The AI Visibility Tracker is the feature that puts Sitechecker in the same conversation as a tool like ContentKing, but it measures something different: whether ChatGPT and Perplexity are actually citing the site in generated answers, not whether their crawlers can technically access it. That's a citation-tracking layer, not a crawl-log layer, and it's unlocked starting on the $219/month Standard tier alongside white-label reports, which strip Sitechecker branding for client delivery.
What Sitechecker doesn't have is API access below Enterprise, a free tier to evaluate before paying, or the crawl depth of an enterprise-grade tool for genuinely complex technical audits. For a small agency running a portfolio of client sites that wants crawling, rank tracking, white-label delivery, and AI citation checks in one subscription at a known price, that's a reasonable trade for skipping the sales call entirely.

Considering AI Peekaboo alongside ContentKing and Sitechecker?
ContentKing tells you whether AI crawlers can reach your pages, and Sitechecker tells you whether ChatGPT and Perplexity are citing two of the engines that matter, but neither gives a self-serve team a full picture of AI visibility with a documented API. ContentKing's Data API and Sitechecker's API are both locked to their top, sales-gated Enterprise tiers. AI Peekaboo ships a read and write API on every plan from $50 per month, tracks five named AI surfaces (ChatGPT, Gemini, Perplexity, Google AI Overviews, Google AI Mode), and includes white-label delivery from day one. For a team whose primary need is AI citation tracking with API access they can actually use at an entry price, it's worth comparing against either of these.

ContentKingSitecheckerContentKingSitecheckerSitecheckerContentKingSitecheckerContentKing and Sitechecker rarely compete for the same budget line, and their "AI" features aren't actually measuring the same thing. ContentKing's log file analysis is a crawl-access diagnostic: it tells a technical team whether GPTBot and ClaudeBot can parse a page correctly, which matters upstream of citation. Sitechecker's AI Visibility Tracker is a citation check: it tells an agency whether ChatGPT and Perplexity are actually surfacing the brand in an answer. A team that needs both signals will end up needing more than either tool alone provides, since ContentKing has no citation tracking and Sitechecker has no crawler log analysis.
Bottom line
Choose ContentKing if you're running a large or fast-changing site, need 60 months of history for root-cause or compliance work, and have the budget and patience for a sales-led enterprise purchase. Choose Sitechecker if you're a small-to-mid agency that wants a crawler, rank tracker, white-label reports, and AI citation checks in one subscription at a published price starting at $89/month. Neither tool is the strongest option if AI citation tracking with full API access is the primary requirement; AI Peekaboo covers that gap at a lower entry price than either.
Frequently asked questions
Is ContentKing still a standalone product, or is it the same thing as Conductor Monitoring?
ContentKing has been fully folded into the Conductor platform and now operates as Conductor Monitoring, though the contentkingapp.com domain still points to it. The 24/7 monitoring and real-time alerting are unchanged, but it now ships as part of a broader Conductor AEO and SEO suite rather than a separate product.
Does Sitechecker's AI Visibility Tracker do the same thing as ContentKing's AI crawler log analysis?
No, they measure different things. Sitechecker's AI Visibility Tracker checks whether ChatGPT and Perplexity are citing the brand in generated answers, which is a citation-tracking feature. ContentKing's log file analysis checks whether AI crawlers like GPTBot and ClaudeBot can technically access and parse a site's pages, which is a crawl-access diagnostic. A site can pass one check and fail the other.
Which tool is cheaper for a small agency to start with in 2026?
Sitechecker is the only one of the two with a published price, starting at $89 per month for the Basic tier. ContentKing has no public pricing on any of its three tiers, Essentials, Growth, or Enterprise, and requires a sales conversation before you see a number, though Essentials does offer a free trial for sites under 100,000 pages.
Can I get API access on Sitechecker without paying for the Enterprise tier?
No, Sitechecker restricts API access entirely to its Enterprise plan; Basic, Standard, and Premium do not include it at any price. ContentKing has the same restriction on its own Data API, which is Enterprise-only as well, so neither tool offers API access at an accessible price point.
Does ContentKing offer white-label reporting for agency clients like Sitechecker does?
ContentKing does not list white-label reporting as a documented feature on any of its tiers. Sitechecker includes white-label reports starting on its $219-per-month Standard tier, which replaces Sitechecker branding with the agency's own for client delivery, making it the more agency-oriented of the two on this specific point.
Is ContentKing worth it if I only care about AI search visibility, not general crawl health?
Probably not on its own. ContentKing's AI-specific feature is limited to crawl-health signals, showing whether AI crawlers can reach your pages, not whether AI models are citing your brand in answers. A team whose primary interest is citation tracking is better served by Sitechecker's AI Visibility Tracker or a dedicated AI visibility platform like AI Peekaboo.
