# I Will Extract Data From Bot-Protected Websites Using a Stealth Browser

Your target blocks normal scrapers — JavaScript walls, basic bot checks, anti-automation scripts. My stealth-browser engine carries a real Chrome fingerprint with no automation flags, and the extraction stays on publicly accessible data that follows each site’s terms.

## WHAT YOU GET

- Data from JavaScript-heavy and bot-checked pages, rendered the way a real visitor renders them
- Pagination and infinite scroll handled from start to finish
- Records normalized: aligned columns, duplicates removed, QC-checked against the source page
- A clean relationship after delivery: if the target changes page structure, I detect it and re-map

## CHOOSE YOUR LEVEL

- **Basic** — 1 site, up to 500 records, delivered in 2 days. A solid first structured export of one target.
- **Standard** — 1 site, up to 5,000 records, pagination plus JavaScript rendering included, delivered in 4 days.
- **Premium** — 2 to 3 sites, up to 15,000 records, with a 30-day maintenance window. If a target changes after delivery, I re-map and update so your data keeps flowing.

## HOW WE WORK

1. **Feasibility check first, always.** You send the target URL and the fields you need; I run a real sample capture and confirm it can be scraped legally and reliably. If it cannot, I tell you straight instead of taking your money.
2. **Scope and confirm.** We agree on the exact record count, columns and delivery date before the clock starts.
3. **Stealth run.** The browser renders the pages like a visitor, works through pagination and dynamic content, and stores every row with its source page.
4. **Cleaning and QC.** Rows are aligned, deduped and format-checked. Every delivery ships with a QA report sheet showing exactly what was extracted, changed and verified.
5. **Delivery.** You receive .xlsx or CSV, ready for your own analysis, CRM or reporting.

## WHY IT’S BETTER

- Real browser fingerprint, no automation flags — basic bot checks and JavaScript walls do not stop the extraction
- Normalized output — no messy rows, no guessed values, every record traceable to its page
- Honest feasibility gate — I confirm before you pay, never after
- Public data only — I follow each site’s terms and robots.txt, and never touch login-gated content

## SEND BEFORE ORDERING

- The target URL(s)
- The fields you need
- Expected volume and whether you need recurring updates

The feasibility check is free and non-binding. Message me a sample page and I will come back with a confirmed price and timeline — no surprises.
