Some sites block simple automated fetches. You might see a captcha, a challenge page, or a blank response when bots are detected. That breaks naive monitoring because there is nothing useful to compare.
What PingChange does on paid plans
Available on paid plans.
For appropriate checks and previews, PingChange uses an automated smart, stealth-oriented browser session designed to behave like a normal visitor. Captchas and common anti-bot walls are handled without a manual switch — the product escalates to this mode when the target needs it so legitimate snapshots can succeed.
You do not need to configure vendor names or technical flags per URL in most cases.
What you should still expect
- Not every site permits automated access under its terms of service. You are responsible for monitoring only URLs you are allowed to watch.
- Extremely aggressive protection may still fail intermittently; if checks error repeatedly, try a slower schedule or contact support with the URL.
- Rate and courtesy — Very fast intervals on heavy pages can trigger defensive blocks; match frequency to how often content truly changes.
