Panel verdict
The AI panel rates OnCrawl 2.5/5, the mean of 6 judges. OnCrawl, from Data On Focus SAS, is a technical SEO platform built around crawling and log analysis: JavaScript-rendered crawls, Core Web Vitals as lab data, log analysis of Googlebot, Bingbot and AI bots at a claimed +500M lines daily, impact reports weighted by organic visits and bot crawl frequency, and a log-based Fresh Rank metric tying first Googlebot crawl to first SEO visit. how scores are made

Read this page as one judge. Each weighs the same scores by what they care about.

The Data Analyst

Weighted verdict

Wants the numbers in the warehouse, not in a PDF. Cares about a documented API with published credit costs, bulk historical export, and whether three years of ranking history leaves with the customer or dies with the subscription.

Same scores as the panel view — this lens weights them the way this judge cares.

Crawling & technical audit

How this is scored

Site crawling at real scale: what the crawler finds, how deeply it checks, whether Core Web Vitals and indexation problems are diagnosed rather than merely listed.

0 — No site crawler; the product is keyword data only.

3 — A crawler with a low page cap that reports broken links and missing tags, with no prioritisation and no rendering of JavaScript.

5 — Scheduled crawls at a stated page limit, JavaScript rendering, issue categories with severity, and Core Web Vitals pulled per template.

8 — Log-file or Search Console integration to compare what the crawler sees against what Google fetched, indexation and canonical diagnosis, structured-data validation, and issues prioritised by traffic impact rather than count.

10 — The audit is diagnostic rather than a list: crawl budget analysed, rendering differences surfaced, regressions detected between crawls with the deploy that caused them inferrable, and remediation guidance specific enough for a developer ticket.

Report an error

The Data Analyst

The crawler is the product's core, with JavaScript rendering at a stated multi-hundred-million-URL scale, Core Web Vitals collected as lab data and broken down per page group against organic visits and bot crawl frequency, and log-file analysis of Googlebot, Bingbot and AI bots cross-referenced with crawl data — that is diagnosis weighted by traffic impact, not a link list. What holds it below the very top: we found no public information on structured-data validation, indexation or canonical diagnosis, or on regression detection between crawls with the deploying change attributable. 1 2 9

Keyword research & content guidance

How this is scored

Keyword discovery, intent classification, SERP feature analysis and on-page guidance — judged on the depth of the German-language data as much as the English.

0 — A keyword list with volumes from one source and no intent or difficulty signal.

3 — Volume and difficulty for major markets, with thin or stale German data and no SERP feature detail.

5 — Keyword research with volume, difficulty and intent across German and other EU markets, SERP feature presence, and basic on-page recommendations.

8 — Topic clustering, competitor gap analysis, SERP composition tracked over time, content briefs with entity coverage, and cannibalisation detection.

10 — Research and guidance close the loop: opportunity sized against realistic traffic, content scored against what currently ranks rather than against a keyword density heuristic, and recommendations that reference the specific pages in the customer's own site.

Report an error

The Data Analyst

What is documented here is query performance imported from Google Search Console, with device and country breakdowns and query grouping, plus a content side offering near-duplicate and similarity metrics with boilerplate exclusion — real, but it is not keyword research. We found no public information on a proprietary keyword database with volumes, difficulty or intent, on SERP feature analysis, or on German-market data depth; the audience-intelligence article names third-party technologies rather than OnCrawl's own tooling. 4 5 7

Rank tracking & index quality

How this is scored

The proprietary data: ranking accuracy and frequency, backlink index size and freshness. Scored on what the vendor documents about their own data, because nothing here can be verified from outside.

0 — Rankings and backlinks with no stated update frequency, no country or device granularity, and no documentation of how either is collected.

3 — Weekly rankings for one country and device, a backlink index with no stated refresh cadence or size.

5 — Daily rankings with country, language and device selection, local results, and a backlink index with a documented crawl frequency.

8 — Rankings at stated frequency across many locations including city-level, SERP feature attribution, backlink index size and refresh published, lost-and-found link detection, and historical data retained for the life of the account.

10 — The vendor is accountable for their own data: methodology documented, index size and freshness published and updated, historical rankings retained and exportable in full, and discrepancies against Search Console explained rather than hidden.

Report an error

The Data Analyst

Every ranking figure the vendor documents is imported from Google Search Console — honestly labelled, with a stated daily refresh, a 16-month recovery on setup, and country and device granularity — but we found no public information on proprietary SERP collection of their own, a backlink index of any size or refresh cadence, or city-level tracking. The Fresh Rank indicator at least publishes its method, computing the lag between first Googlebot crawl and first organic visit from log files. 6 7

Reporting, integrations & API

How this is scored

Getting the data out and in front of someone: dashboards, white-label reporting for agencies, Search Console and analytics integration, and an API a team can build on.

0 — On-screen views only; export is a manual CSV and there is no API.

3 — Scheduled PDF reports and CSV export, one analytics integration, no API worth building against.

5 — Customisable dashboards, scheduled reports, Search Console and analytics integration, and a documented API with stated limits.

8 — White-label reporting with client access, data-warehouse or BigQuery export, multi-site and multi-client management, and an API with credit costs published per endpoint.

10 — The tool is a data source rather than a destination: full historical export in open formats, a versioned API with a deprecation policy, integrations the vendor maintains, and reporting an agency can hand a client unedited.

Report an error

The Data Analyst

This is close to the shape I want: a documented API on a developer subdomain with reference documentation, guides, code samples, token and OAuth authentication with granular permissions, every chart publishing the API call that produced it in their OQL query language, and crawl profiles creatable, modifiable and schedulable programmatically. Crawl and link data land in a Looker Studio connector or your own GCS or S3 bucket. It stops short of the top because we found no public information on credit or rate-limit costs per endpoint, on white-label client reporting, or on an API versioning and deprecation policy. 8 9 10

Report an error

Data portability & exit

How this is scored

Whether the ranking and crawl history — the only thing a multi-year subscription actually accumulates — remains the customer's when they leave.

0 — No bulk export; history is visible in the interface and nowhere else, and ends with the subscription.

3 — CSV export of current views only, with historical data capped or unavailable in bulk.

5 — Bulk export of rankings, keywords and crawl results including history, via interface or API.

8 — Complete historical export in open formats without credit metering that prices it out of reach, plus a documented retention period after cancellation.

10 — Exit is designed for: the full account exportable including every historical data point, API access sufficient to mirror the data continuously, and a stated grace period during which the archive remains retrievable.

Report an error

The Data Analyst

Bulk export is engineered for, not bolted on: page, link, raw HTML, cluster, keyword and structured-data datasets exported in JSON, CSV or Parquet to the customer's own S3 or GCS bucket, with API endpoints that report status and failure reasons, and we found no public information on credit metering that would price exports out of reach. What keeps it from the top: we found no public information on exporting the Search Console query history itself, on a retention period after cancellation, or on a grace period during which the archive remains retrievable — exports are documented as requiring an active subscription. 1 10 11

European sovereignty

How this is scored

Where the account and crawl data live and who the contracting entity is. Independently sourced by the sovereignty pipeline; weighted lower here than in categories holding personal data, because an SEO tool mostly holds the customer's own strategy rather than their customers' identities.

0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and site or user data of unclear scope leaving the EU.

3 — EU hosting offered as an option while the contracting entity is non-EU, or the subprocessor list is absent.

5 — EU hosting as standard and an EU contracting entity, but parts of the chain are non-EU without an explained safeguard.

8 — EU hosting on named infrastructure, EU contracting entity, subprocessor list published, and any analytics or Search Console data handling described with its legal basis.

10 — Sovereign end to end and evidenced: vendor, entity, hosting and every subprocessor European, certification published, and a DPA that covers the crawl and analytics data the tool ingests.

Report an error

The Data Analyst

The contracting entity is named as a French société par actions simplifiée, which points to an EU entity, but that is where the record ends: we found no public information on hosting location or named infrastructure, subprocessors, certification, or a data processing agreement covering the crawl, log and Search Console data the platform ingests. A vendor page and help center that describe analytics integrations in detail stay silent on where that data resides. 1

Pricing transparency not rated — the vendor publishes no price

How this is scored

The category where the headline price is least often the invoice. Whether a buyer can compute the real annual cost including keyword limits, crawl credits, API units, extra users and client seats — from public pages alone.

0 — No public prices at all; every tier is a sales conversation.

3 — A monthly headline exists, but keyword limits, crawl credits or the cost of an additional user are unstated — the invoice is unknowable.

5 — Tier prices public with the main limits given, but at least one commonly needed piece (extra seats, API credits, historical data) is unpriced or metered opaquely.

8 — Every tier priced publicly with keyword, crawl and API limits, overage rates, per-seat costs, minimum term and VAT treatment stated.

10 — Complete price computability: annual invoice derivable for a given keyword count, crawl volume, API usage and team size, with overage and every credit cost published.

Report an error

The Data Analyst

No captured page states a price, a tier, a crawl or page quota, a per-seat cost, VAT treatment or a minimum term; even the Looker Studio connector is gated on an unnamed plan feature with no figure attached. A buyer cannot compute any part of an invoice from public information, so this sits at the lowest published level. 1 8
