Semrush vs SISTRIX

Semrush

The captured audit material runs well past a checklist: crawlability and indexability, canonicals, structured data, mobile parity and rendering, AI crawler access, Core Web Vitals judged against Google's good/needs-improvement/poor bands at the 75th percentile, a snapshot-based workflow across crawls, and multi-million-page crawling at the enterprise tier. It stops short of genuine diagnosis: we found no public information on log-file analysis, crawl budget analysis, or prioritisation by traffic impact rather than count — the only phrasing captured is a prioritized fix list — and regression detection between crawls is likewise undocumented.

SISTRIX

Scheduled weekly crawls at a stated scale of 30,000 to 4,000,000 URLs per month, JavaScript crawling described as using the same technology as the official Googlebot, error categories shown with per-crawl deltas, automated change detection, and Core Web Vitals from both daily permanently stored Lighthouse lab runs and field data. We found no public information on log-file analysis, crawl budget, indexation or canonical diagnosis, or issues prioritised by traffic impact rather than generic importance.

Semrush

Volume, difficulty and CPC across a 26.4-billion-keyword database, SERP feature detection down to AI Overviews, a 30-day SERP volatility chart, cannibalisation analysis and content optimisation on the higher tiers — real research depth. We found no public information on intent classification, topic clustering, or content briefs with entity coverage, and nothing captured speaks to the depth of the German-language data specifically.

SISTRIX

Volume, click prices and competition intensity, intent derived from SERP structure with a published points breakdown, automatic topic clustering and competitor keyword analysis by URL, with the German-language database marketed as the largest for the German and European market. We found no public information on SERP composition tracked over time, entity coverage in content briefs, or cannibalisation detection.

Semrush

Daily position updates at city and country level on desktop and mobile, a published 43T backlink index, 26.4B keywords across 142 geo databases, and monthly snapshots back to 2012-01 — the vendor puts its own numbers in public. But we found no public information on the backlink index refresh cadence or lost-and-found link detection, and the terms permit erasure of all customer data not less than thirty days after termination, so retention for the life of the account is not evidenced.

SISTRIX

The update cadence is documented in detail — daily for the most important keywords, weekly for notable volume, at least monthly for everything, with automatic cycle shifts on demand change — plus city-level queries, over 200 country/language combinations, device selection and history retained up to eleven years on higher packages. The backlink side is undocumented: we found no public information on index size or refresh cadence, lost-and-found link detection, or how discrepancies against Search Console are handled.

Semrush

Strong: white-label Pro Reports at €19.18/mo with twenty-plus external integrations and sharing by link, Base Report at €9.59/mo with Google Analytics and Search Console integrations, multi-site management across tiers, OAuth 2.0 and MCP access, and API credit costs published per operation — 20 API units per request for keyword metrics, a points-times-keywords credit formula for Map Rank Tracker, and a checkable unit balance — with v3 deprecated as v4 arrives. We found no public information on data-warehouse or BigQuery export.

SISTRIX

A documented API with JSON or XML responses, a request sandbox, a fair-use policy and examples in four languages, with weekly credit allocations per package and a pack of 10,000 credits per week priced at 75 euros monthly, alongside per-tier dashboards and reports, Search Console and analytics connection, and connectors to Google Data Studio (noted as still in development), Google Sheets, Excel and an MCP server. We found no public information on white-label client reporting, data-warehouse or BigQuery export, or API versioning and deprecation policy.

Semrush

Export runs in open formats — JSON and CSV over the API, keyword history back to 2012-01, Site Audit snapshots retrievable — and the exit terms are at least written down: thirty days to back up after suspension, erasure no sooner than thirty days after termination. But export consumes metered API units, and the terms bar caching retrieved data beyond one month without written consent, which turns continuous mirroring of your own history into a negotiation; we found no public information on a complete account export or a stated archive grace period.

SISTRIX

Table export via a download button as UTF-8 CSV, alternatives in Excel and Google Sheets, charts as PDF, CSV or PNG, raw stored Lighthouse JSON downloadable, and machine export via the API, with history retained up to the tier limit — only 3 months on the smallest package. Exports are metered by weekly credits, and we found no public information on a retention period after cancellation or on exporting every historical data point in one pass.

Semrush

The captured pages show a Delaware corporation contracting from Boston, personal data transferred to the United States and to affiliates' jurisdictions, and no stated data residency, hosting location, or core subprocessor list. Standard Contractual Clauses and an EU joint controller in Prague are the only European footholds evidenced, so this sits just above the bottom.

SISTRIX

The contracting entity is named as SISTRIX GmbH on the vendor's own pages, but the only hosting statement we found is homepage marketing copy saying data is kept in "Europa", with no named infrastructure provider and no privacy policy or DPA excerpt corroborating it. We found no public information on subprocessors, on the legal basis for the Search Console and analytics data the tool connects, or on certification.

Semrush

The captured pricing pages are granular where they speak: 5 to 40 websites and 500 to 5,000 daily tracked keywords by tier, additional users starting at €43/mo, Base Report €9.59/mo, Pro Report €19.18/mo, fees exclusive of taxes, and cancellation at the end of the prepaid period. But we found no public information on the headline price of each tier, on crawl limits per tier, or on what an API unit costs — the annual invoice is not computable from the captures.

SISTRIX

All four packages priced per month with VAT stated as excluded, monthly cancellation, extra users at 24,90 €, additional projects at 9,90 €, 8,49 € and 5,99 €, additional crawled pages at 0,21 €, 0,16 € and 0,14 € per 1,000, and crawl and weekly API credit limits stated per package. API costs are described only as typically based on the number of data points retrieved rather than a per-endpoint price list, and keyword limits appear as projects and SERP updates rather than a plain keyword count.
