One-Site Text Scraper Automation

I need a small yet reliable script that automatically pulls text-based information from a single website and stores it in a clean, structured format I can use for ongoing market research. Frequency will be regular (daily or on-demand), so the solution should handle scheduling and avoid detection blocks or rate limits.

Here is what I’m after:
• Scrape only the textual content I specify—no images required.
• Parse the raw HTML into clearly labeled fields (CSV or JSON is fine).
• Build in error handling, simple logging, and the ability to update selectors if the site layout changes.
• Deliver ready-to-run code (Python with BeautifulSoup/Scrapy + requests, or a similar stack you’re comfortable with) along with brief setup instructions.

Acceptance criteria:
1. Script runs locally on my machine with one command.
2. Output file contains 100% of the target text elements for a sample run.
3. No captchas triggered or IP blocks after three consecutive runs.

If you have questions about the site or want to suggest optimizations, let me know—speed of execution and clarity of the harvested data are the main priorities.
