If scrapy is ineffective in gathering items, the following steps can be taken:
- Check the website's robots.txt file to ensure that it is not blocking the crawler.
- Verify that the xpath or css selectors are accurate and up to date.
- Increase the download delay and/or the number of concurrent requests.
- Use proxies to bypass IP blocking.
- Consider using a different web scraping tool or library.
- Contact the website owner to request permission to scrape their website.
- Verify that the website is not using dynamic pages and that the scraper is configured to handle JavaScript and Ajax content.
- If all else fails, manually extract the data by copying and pasting or using a web scraper extension in a web browser.
