Screaming Frog for Technical AEO Auditing: Schema Extraction, Heading Audits, and AI Agent Simulation
Screaming Frog SEO Spider is the go-to desktop crawler for technical AEO audits - combining bulk schema extraction, heading structure analysis, and user agent simulation into a single configurable tool. For AEO practitioners, Screaming Frog's custom extraction and JavaScript rendering capabilities extend its value well beyond traditional SEO crawl use cases, enabling systematic identification of schema gaps, heading hierarchy violations, and AI crawler accessibility issues across entire sites.

Screaming Frog for Technical AEO - 3 Workflows
Schema extraction configuration
Screaming Frog's Custom Extraction feature uses XPath, CSS selectors, or regex to extract JSON-LD schema data from crawled pages - enabling bulk schema validation at scale. AEO workflow: (1) Set custom extraction targets: XPath //script[@type='application/ld+json'] extracts all JSON-LD from every crawled page. (2) Export the extraction results to spreadsheet, then parse with a JSON schema validator (or a simple Python script) to identify pages with: missing required schema properties, schema type mismatches vs page content, or no schema at all. (3) Cross-reference schema type coverage against a master list of your target schema types (FAQPage, HowTo, Article, etc.) to identify systematic gaps - pages that should have FAQ content but lack FAQPage schema.
Screaming Frog custom extraction setup:
XPath: //script[@type='application/ld+json']
→ Extracts all JSON-LD from each page
→ Export to CSV → parse with Python json.loads()
Detection logic (Python):
import json, csv
with open('schema_extract.csv') as f:
for row in csv.DictReader(f):
try:
schemas = json.loads(row['Extracted 1'])
types = [s.get('@type') for s in
(schemas if isinstance(schemas, list)
else [schemas])]
if 'FAQPage' not in types:
print(f"Missing FAQ: {row['Address']}")
except: pass
