How scores are made: https://whats-best.ai/methodology ## At a glance - Vendor: OnCrawl (Data On Focus SAS) - Headquarters: Not stated on the vendor’s pages as of 13 Oct 2026 - Data hosting: Not stated on the vendor’s pages as of 13 Oct 2026 - Free plan: Not stated on the vendor’s pages as of 13 Oct 2026 ## The panel's verdict 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. Technical audit scores cluster at 8 and data portability at 7-8; reporting and API scores of 6-7 reflect a documented API that publishes its own calls on every chart and pushes datasets to the customer's S3 or Google Cloud Storage bucket in JSON, CSV or Parquet. The weakest areas are keyword and content, rank and index data and sovereignty: query data is an honestly labelled, daily Google Search Console import with a 16-month recovery, and we found no public information on a keyword database, a backlink index, hosting location, subprocessors or a data processing agreement. No criterion spans more than one point, and no captured page states a price. **Speaks for it:** - Technical audit scores cluster at 8, on JavaScript-rendered crawling, Core Web Vitals as lab data per page group, and log analysis cross-referenced with crawl and analytics data. - Issues are weighted by organic visits and bot crawl frequency rather than raw issue counts. - Fresh Rank computes the average days between first Googlebot crawl and first SEO visit from the customer's own log files. - The API is documented with token and OAuth authentication, code examples and every chart exposing its own API call, plus a Looker Studio connector with an included template. - Data portability scores cluster at 7-8, with page, link, raw HTML, cluster, keyword and structured-data datasets exportable to the customer's own S3 or Google Cloud Storage bucket in JSON, CSV or Parquet. **Held against it:** - Keyword and content scores sit at 2-3; query data comes from Google Search Console, and we found no public information on keyword volumes, difficulty, intent or SERP feature data. - Rank and index data scores sit at 3-4; we found no public information on a backlink index, city-level tracking or a ranking collection of the vendor's own. - Sovereignty scores sit at 2-3; we found no public information on hosting location, subprocessors, certifications or a data processing agreement beyond the vendor's French company form. - Exports are documented as requiring an active subscription and an API token, and we found no public information on retention or a grace period after cancellation. - We found no public information on stated API rate limits, per-endpoint credit costs or white-label client reporting. **Best for:** - You run technical audits on large or complex sites and want crawl, log and Core Web Vitals data cross-analysed and weighted by organic traffic impact. - Your team builds its own reporting pipelines and wants a documented API with OAuth, programmatic crawl scheduling and open-format exports to your own cloud bucket. - You monitor how Googlebot, Bingbot and AI bots crawl your site and want log-based signals such as Fresh Rank. - You already own keyword research elsewhere and want a technical complement rather than an all-in-one suite. **Avoid if:** - You need native keyword research with volumes, difficulty and intent in the same tool; the bench scored keyword and content at 2-3. - You need rank tracking or backlink data from the vendor's own index, since ranking figures here are Google Search Console imports. - Your procurement requires documented hosting, subprocessor or data-processing-agreement terms before you hand over raw server logs and Search Console data. - You need post-cancellation archive access; exports are documented as requiring an active subscription. ## Scores by judge and criterion Scores out of 5, each judge scoring independently against the published rubric (v1).

Wants German-language keyword data that is not an afterthought, rankings she can defend when they disagree with Search Console, and audit findings specific enough to become a developer ticket. - **The Agency Owner** (v1.0): Runs forty client sites and rebills the licence. Wants multi-client management, white-label reports a client can receive unedited, and per-seat costs that do not punish a growing team. Reads "contact us" on a pricing page as a margin problem. - **The Technical SEO** (v1.0): 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. - **The Content Strategist** (v1.0): Decides what gets written and can only commission so much. Wants topic clusters, honest opportunity sizing, cannibalisation caught before it happens, and briefs scored against what actually ranks rather than against keyword density. - **The Data Analyst** (v1.0): 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. - **The Skeptic** (v1.0): Knows every vendor claims the largest index and the most accurate rankings, and that no buyer can check either. Reads instead for what can be held to: refresh frequency, stated limits, credit costs per endpoint, and what the invoice does when the team adds a seat. ## European sovereignty — proven facts No sovereignty finding yet. ## Key facts Each fact is the vendor's own statement, cited to the source page it was read from ([S*n*] → Sources). **Integrations** - API: API and cross-referencing with GSC API and spreadsheets (testimonial) [S1] - API auth methods: api_token · oauth_application [S9] - API docs URL: https://developer.oncrawl.com/ [S9] - API metrics: crawl data · log file data · cross-analysis data [S9] - API token permissions: account read · account write · project read · project write [S9] - Charts API calls info: Charts show API calls and response format via info icon, "API calls" tab [S9] - Docs contents: reference documentation · guides · code examples [S9] - Gcs service account roles: roles/storage.legacyBucketReader · roles/storage.legacyBucketWriter · roles/storage.legacyObjectReader · yes [S10] - Looker studio data available: crawl data from all fetched pages · yes [S8] - Looker studio feature gated: yes · Looker Studio [S8] - Looker studio fields list URL: http://developer.oncrawl.com/#Fields [S8] - Looker studio key separate from API key: Looker Studio access key is separate from the Oncrawl API key; API feature does not imply Data Studio access [S8] - Looker studio viewer credentials tip: Using Viewer Credentials prevents viewer calculations from consuming quota [S8] - Raw data export: yes [S1] **Pricing** - Cwv option: yes · yes · contact via chat [S2] - Looker studio quota limit: 1TB [S8] - Looker studio quota monthly: anniversary date of subscription · monthly [S8] **Product** - Access options: crawl report sidebar · Show Ranking performance button on project page [S7] - Activation required: yes [S7] - AI search coverage: covers traditional and AI search [S1] - API automation: create and modify crawl profiles · run and schedule crawls · other account actions [S9] - Audience first SEO methodology: audience-first SEO strategy integrating keyword intelligence and audience intelligence [S4] - Audience integrations named: article references Audiense, Pulsar, Helixa and SparkToro as audience intelligence technologies [S4] - Big data export gcs: yes · Send crawl and link data to a Google Cloud Storage bucket [S10] - Capabilities list: Crawler · Log Analyzer · Lenses · AI Search Lens · Content Lens [S1] - Capabilities list: Crawler · Log Analyzer · Lenses · AI Search Lens · Content Lens [S4] - Country performance: yes [S7] - Crawl log performance data: collects, cross-references, and analyzes crawl, log, and performance data with zero sampling [S1] - Cwv crawl report: Crawl Report > Performance > Core Web Vitals · yes [S2] - Cwv crawl setup: crawl extra settings > Crawl JS settings · JavaScript · Core Web Vitals [S2] - Cwv dashboard location: crawl analysis dashboards · Data Explorer · URL details [S2] - Cwv default device: desktop · yes [S2] - Cwv field data context: staging websites · newly created URLs · newly updated URLs [S2] - Cwv impact report dimensions: organic visits per page · organic traffic presence · bot crawling presence · bot crawl frequency [S2] - Cwv lab data basis: lab data [S2] - Cwv lighthouse audit: yes [S2] - Cwv metrics collected: FCP · CLS · LCP · TTI · Speed Index · TBT · Performance Score [S2] - Cwv report contents: site-wide performance on all metrics · site-wide CWV metrics · breakdown by page group for any segmentation · potential optimization gains [S2] - Cwv SEO impact report: yes · log files · Adobe Analytics · Google Analytics · Piano Analytics [S2] - Cwv tbt instead of fid: no · yes [S2] - Daily import: yes [S7] - Daily log lines: +500M [S1] - Dashboards available: query · query_groups · page_groups [S7] - Data studio export completed crawls: yes · archived crawls must be unarchived first [S8] - Data studio export from crawl profile: Enable export to Data Studio checkbox in crawl profile · yes [S8] - Data studio source: yes [S7] - Date comparison: yes [S7] - Default period: 45 [S7] - Device breakdown: mobile · tablet · desktop [S7] - Exclude content affected metrics: .word_count · n_grams · near_duplicate_signature · similarity_ratio [S5] - Exclude content crawl profile: yes [S5] - Exclude content feature: filter out dense, redundant content from analysis · yes [S5] - Exclude content js mode: yes [S5] - Exclude content linking unaffected: no [S5] - Exclude content preview: yes [S5] - Exclude content selectors: #id · .class ·
