If the API rate limit is very strict, I distribute requests across multiple accounts with different API keys to maximize throughput.

For sites with date filters, I automate date selection in the form or URL parameters to scrape data for specific periods.

Capturing and storing form data as I go allows me to pick up where I left off if the script stops unexpectedly. This is crucial for long, multi-page forms.

Encountering CAPTCHAs mid-scrape can stop the script. I’ve found that using services like 2Captcha or rotating proxies helps minimize this.

I disable JavaScript initially to see if the content is still accessible. If it isn’t, then a headless browser is likely needed.
