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

The Technical SEO

Weighted verdict

Lives in crawl data and log files. Wants JavaScript rendering, crawl budget analysed, indexation diagnosed rather than listed, and regressions caught between crawls. Treats an issue list sorted by count rather than by traffic impact as busywork.

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 Technical SEO

This is my kind of tool: a crawler with JavaScript rendering, Core Web Vitals collected as lab data per URL and per page group with Lighthouse on demand, then cross-analysed against log files and analytics so issues are weighted by organic visits and bot crawl frequency rather than counted. Log monitoring with Fresh Rank — days between first Googlebot crawl and first organic visit — is genuine crawl-budget analysis, and orphan-page and internal-linking diagnosis sits alongside it. What keeps it from the top of the scale: we found no public information on canonical or indexation diagnosis as a feature, structured data appears only as an export dataset rather than validated, and no regression detection between crawls with deploy attribution. 1 2 5 6 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 Technical SEO

Keyword research as a data product barely appears: the only query data is a Search Console import reporting clicks, impressions, position and CTR, while the audience-first and topical-modelling material is methodology prose pointing at third-party tools such as Audiense and SparkToro rather than a keyword database. What is real is crawl-side content analysis — near-duplicate signatures, similarity ratios, n-grams and boilerplate exclusion with a JavaScript-rendered preview. We found no public information on keyword volume, difficulty, intent or SERP-feature data, or on the depth of the German-language data. 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 Technical SEO

There is no proprietary ranking index here: rankings come from a Search Console import, documented honestly with daily updates, a 16-month backfill, country and device splits and even a sampled-versus-unsampled view — but it is Google's data relayed, not their own collection, and it must be activated per project. Fresh Rank derived from log files is a genuinely proprietary index-quality signal, and bot-log processing at claimed scale backs it. We found no public information on a backlink index, its size, refresh cadence or any collection methodology of their own. 1 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 Technical SEO

This one you can build on: a documented developer portal with token and OAuth authentication, granular scopes, every Data Explorer metric — crawl, log and cross-analysis data — reachable through an Elasticsearch-overlay query language, and charts that publish their own API calls so any visualisation can be lifted into code. Crawl profiles can be created and scheduled programmatically, there is a Looker Studio connector with templates, and bulk export lands in Google Cloud Storage or S3 in JSON, CSV or Parquet. We found no public information on rate limits or credit costs per endpoint, on white-label client reporting, and the Looker Studio connector is gated behind a plan feature. 8 9 10

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 Technical SEO

The exit plumbing exists and it is serious: an export API that pushes page, link, raw HTML, cluster, keyword and structured-data datasets to the customer's own S3 or Google Cloud Storage bucket in open formats, with status reporting and error emails — no credit metering on exports appears anywhere. The catch is in the prerequisites: an active subscription and non-archived crawls. We found no public information on retention or a grace period after cancellation, so as far as the captured pages show, history retrieval ends when the subscription does. 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 Technical SEO

The sovereignty record came back empty: the captured pages say nothing about where accounts or crawl data are hosted, name no subprocessors, and offer no DPA or certification detail — only the vendor's French legal form, Data On Focus SAS, hints at a European contracting entity. The exports land in customer-chosen Google or AWS buckets, which is a data-location decision the customer makes rather than a documented European chain. 1 10

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 Technical SEO

We found no public information on pricing in the captured pages: no tier prices, no crawl or keyword limits, no seat costs, no VAT treatment. The only pricing-adjacent fact is that Looker Studio access depends on a plan feature whose price is never stated, so a buyer cannot begin to compute an annual invoice from what is public here. 1 8
