What if a site changes frequently?

We monitor all target sites automatically. When changes happen, our team patches extraction rules - typically within 24-48 hours. High-change sites get more frequent dry runs. You're notified if delivery is at risk.

Yes. We can provide dry run results, fix history, run metrics, and QA sign-off documentation. Audit trail available for compliance-sensitive clients.

99%+ delivery reliability. If an issue affects your scheduled delivery, you're notified proactively before the deadline.

What happens if you can't get data from a site?

We assess feasibility during the scoping call. If a site becomes inaccessible mid-project, we notify you immediately and discuss alternatives. You're never charged for data we can't deliver.

Data Quality | ProWebScraper

Q: Do you support real-time data?

Most clients use batch delivery (daily/weekly). For near-real-time needs, we offer hourly updates on high-priority sites. True real-time streaming is available for specific use cases - ask us.

4-Stage QA Process

Problems found before they reach you — not after.

Data Format Setup

Fields and formats locked in before we write any code. If the main method fails, two backup methods ensure data still ships complete. Your data format doesn't change without your sign-off.

Test Run

Day before delivery: test 10–15 random URLs per site. Format issues or site changes caught here and fixed before your delivery.

Full Run

We run and monitor the full collection. 95%+ of products successfully collected per delivery. Every data point validated — correct prices, right currencies, no missing fields. Our team flags anything unusual.

Pre-Delivery Review

Human review before delivery. Unclear prices, unusual listings, borderline stock status — flagged and resolved. Nothing ships with a known issue.

Frequently Asked Questions

What does "98%+ accuracy" mean?

Most vendors measure whether a product was found on a competitor's site. We measure whether every data point in your file is correct — the price, the currency, the stock status, the variant. A product can be "found" on 100% of sites and still have wrong prices in 40% of rows. We target 98%+ accuracy at the individual data point level, not at the page level.

How often do sites break?

Sites change layouts 2–4 times per year. At 10 sites, that's 20–40 breaks annually. One enterprise client with 150+ sites sees 30–35 site fixes per week. Our test run system catches most before they affect delivery.

What kind of errors does your QA catch?

Real examples from client projects: garbled characters in price fields (1,820 ;$ cleaned to $1,820), sale price and full price swapped (so markdown looks higher than regular), local currency labels instead of standard codes (lei corrected to RON), leading zeros stripped from product IDs (breaks catalog matching), size and stock count mismatches. Each run typically produces 10–100 issues per site out of ~3,000 records.

What if a site changes and you can't fix it in time?

You're notified before delivery is late. Standard fix: under 2 hours. Complex fixes (full redesign, new anti-bot): up to 24 hours. We never deliver silently wrong data.

What if I don't trust your accuracy claims?

Send us 50 products from 3 competitor sites, we deliver data in 48 hours, you spot-check against the live sites. Every data point includes the source URL and timestamp. If you find errors, we fix them. If you don't, you've proven it yourself.

Can I see QA logs?

Yes. Dry run results, fix history, collection metrics, and quality sign-off reports. Full audit trail for compliance-sensitive clients.

Do you support real-time data?

Most clients use daily or weekly batch delivery. Hourly updates available for high-priority sites. Real-time streaming for specific use cases — ask us.

What if you can't get data from a site?

We assess feasibility during scoping. If a site becomes inaccessible mid-project, you're notified immediately. You're never charged for data we can't deliver.
