Use `waitUntil: 'networkidle0'` when you need all network connections to be finished, suitable for pages that perform a lot of background tasks.
Opt for `waitUntil: 'networkidle2'` to wait until there are no more than 2 network connections for at least 500 ms, which is a good balance between speed and reliability.
When using `page.waitForSelector()`, specify whether the element should be visible (`visible: true`) or just present in the DOM.
Utilize `page.waitForTimeout()` sparingly as it introduces fixed delays; instead, prefer waiting for specific conditions or elements to improve test efficiency and reliability.
Ensure that the selector used in `page.waitForSelector()` is accurate and unique to avoid timeouts due to non-existent elements.
Adjust the timeout settings in `page.waitForSelector()` and `page.waitForTimeout()` to suit the expected load times and responsiveness of your target website.
Keep Puppeteer updated to benefit from improvements and fixes for waiting functions and overall stability.
Test different `waitUntil conditions` to find the optimal setting for each specific scenario, as this can significantly affect the performance and reliability of your Puppeteer scripts.
