MULTI-WEBSITE SCRAPING
Multi-Website Scraping for Unified Data Across Sources.
Extract structured data from multiple websites and combine it into a single, normalized dataset. Each source is scraped with its own custom workflow, then deduplicated and mapped to one consistent schema — so downstream systems receive clean, unified records regardless of how each source presented the data.
- 2 to 100+ source websites
- Unified schema across sources
- Deduplication & normalization
- API, database, CSV & JSON delivery
OVERVIEW
Multi-website scraping for unified, normalized datasets.
Most businesses need data from more than one website. Pricing intelligence requires comparing products across multiple retailers. Market research requires tracking trends across many competitors. Real estate analysis requires aggregating listings from dozens of portals. But each website presents data differently — different field names, different structures, different update frequencies, and often overlapping records.
Multi-website scraping solves this by treating each source individually at the extraction level, then normalizing and deduplicating at the delivery level. Each source gets its own purpose-built workflow that respects its structure, pagination model, and rendering behavior. Those workflows feed into a unification layer that maps fields into your target schema, removes duplicate records, and validates the result.
Every multi-website engagement produces a single, consistent dataset — where the source of each record is preserved, but all records share the same schema regardless of where they came from. This makes downstream analytics, pricing decisions, and application integration dramatically simpler.
CAPABILITIES
What our multi-website scraping service handles.
Every workflow is engineered around the specific sources, fields, and unification requirements of your project.
Per-source workflows
Each website gets its own extraction logic tuned to its structure and rendering model.
Unified schema
Field names and structures are normalized across sources into one consistent schema.
Deduplication
Detect and merge duplicate records that appear across multiple sources.
Field mapping
Map source-specific field names to your target schema, including transformations.
Source tagging
Every record includes its source identifier so you can trace data back when needed.
Cross-source validation
Apply consistency checks across sources so unified records meet the same quality bar.
Synchronized scheduling
Run all sources on the same schedule so comparisons are always apples to apples.
Monitoring across sources
Monitor each source independently so a change in one doesn't break the whole pipeline.
WORKFLOW
A structured approach to multi-website scraping.
FIELDS
Define exactly what you need.
Multi-website workflows can output any combination of listing, source, and unified fields your downstream systems require.
| FIELD | TYPE | EXAMPLE |
|---|---|---|
| title | String | Wireless Noise-Cancelling Headphones |
| identifier | String | WH-210 |
| url | URL | https://…/listing/123 |
| image | URL | Thumbnail image URL |
| price | Number | 2499 |
| currency | String | INR |
| source | String | example-retailer.com |
| source_type | String | retailer / marketplace / directory |
| source_id | String | SRC-001 |
| source_url | URL | https://example-retailer.com/listing/123 |
| unified_category | String | Electronics › Audio |
| unified_brand | String | Example Brand |
| normalized_price | Number | 2499.00 |
| match_group | String | GRP-WH-210 |
| duplicate_of | String | (empty / record id) |
| captured_at | Datetime | 2026-10-02T09:00:00Z |
| run_id | String | run-2026-10-02-01 |
| source_checksum | String | Source record hash |
| unified_checksum | String | Unified record hash |
Field availability depends on each source. Custom field mapping is available for any unified schema.
DELIVERY

FAQ
Multi-Website Scraping — frequently asked questions.
What is multi-website scraping?
Multi-website scraping is the process of extracting data from multiple websites and combining it into a single, normalized dataset. Each source is scraped with its own custom workflow, then unified into a common schema with deduplication and validation.
How many websites can you scrape in one workflow?
We support anywhere from 2 to 100+ source websites in a single unified workflow. Larger sources counts are built with per-source pipelines that feed into a common delivery layer.
How do you handle different field names across sources?
Each source has its own field mapping. During development, we map source-specific field names to your target schema, including any transformations required (currency conversion, unit normalization, category mapping).
How do you prevent duplicate records across sources?
We use deduplication logic based on stable identifiers (such as SKU, product ID, or a cross-source match group) to detect duplicates. Duplicates can be merged, flagged, or kept separate depending on your downstream requirements.
Can I still identify which record came from which source?
Yes. Every record includes a source identifier and source URL, so downstream systems can trace data back to the origin.
How is the data delivered?
Data can be delivered through REST APIs, JSON, CSV, Excel, direct database inserts, scheduled feeds, cloud storage, or custom integrations.
Can multi-website scraping run on a schedule?
Yes. Workflows can run once, daily, hourly, or on fully custom schedules, with all sources processed in the same run for consistent comparisons.
How do you monitor multiple sources in production?
Each source is monitored independently. If one source changes its structure or stops working, we detect it and update that source's workflow without affecting the others.
What does the pricing include?
Pricing covers per-source analysis, workflow development, unified mapping logic, sample validation, ongoing monitoring, deduplication, schema validation, and delivery through your chosen format.
Can I request a sample before committing?
Yes. We provide a unified sample dataset covering all target sources so you can review the fields, structure, and deduplication logic before scaling.
