Avoid unnecessary parsing. I directly extract data from JSON or API endpoints whenever possible, as parsing HTML takes more time.

If the site uses tokens, I ensure my scraper refreshes the token periodically. Some sites use expiring tokens, so my scraper checks for updates to avoid errors.

Some sites use cookies to track users, so I enable cookies in my scrapers. Libraries like Requests in Python support cookie handling with session objects, which makes this easier.

Node.js has a larger ecosystem for web development and can be quicker to develop with, but Go is better suited for high-performance, high-scale applications.

NoSQL databases are better for flexible, high-speed applications like real-time analytics or social media platforms.
