## Briefing
- Crawlbase: Crawlbase released a blog post covering changes from Cloudflare, DataDome, and Akamai in 2026, along with guidance on distinguishing blocks from parser failures and evaluating fixes by cost per usable result.

## Why it matters
This guide consolidates practical knowledge for web scrapers navigating an increasingly hostile anti-bot landscape. By focusing on cost per usable result, it shifts the conversation from purely technical evasion to economic trade-offs, which is critical for teams building sustainable extraction pipelines.

## Sources

## Watch next
Will the cost-per-usable-result metric become a standard KPI for scraping operations?
