Screaming Frog vs AuditMySite — which is better?

Screaming Frog and AuditMySite occupy adjacent — not overlapping — slots in a modern SEO stack. Screaming Frog is a desktop crawler purpose-built for forensic inspection: it gives you the raw data, the filters, the CSV. AuditMySite is a managed audit-plus-execution platform: it identifies issues and then ships the fixes via your CMS, CDN, or GitHub. Treating them as substitutes misses the point.

If your priority is investigative depth — chained redirects, log-file analysis, custom extraction with XPath, comparing two crawls byte-by-byte — Screaming Frog is the canonical tool. Its filter interface and crawl-comparison mode are unmatched. The trade-off is operational: it runs on a workstation, requires a Chromium install for JS rendering, and outputs CSVs that an engineer then has to translate into deploys.

If your priority is time-to-fix — passing Core Web Vitals before the next Google update, deploying LegalService schema before the next AI Overview refresh, recovering lost rankings before quarter-end — AuditMySite collapses the audit-to-deploy loop. The same scan that flags missing schema also generates the JSON-LD and pushes it via the CMS adapter. The same scan that flags an image-LCP regression generates the resized WebP and uploads it to your CDN. No engineer cycle required for ~85% of findings.

AuditMySite also covers signals Screaming Frog explicitly leaves out: AI Overview citation tracking, llms.txt parity, GEO readiness scoring, and revenue-weighted prioritisation. Conversely, AuditMySite does not replace Screaming Frog for log-file analysis, custom-extraction at scale, or comparing two crawls forensically — that remains Screaming Frog's home turf.

Most growth and SEO teams we work with run both: Screaming Frog quarterly for the deep technical audit, AuditMySite continuously for monitoring, drift detection, and fix execution. The combined cost (~£199/year + £29-£149/month) is materially below a single mid-tier agency retainer and produces a tighter feedback loop than either tool alone.
