[INSANE SPEED] How are these instruments indexing URLs in underneath 2 minutes? Is it secure?

I’ve been testing some high-speed indexing instruments not too long ago, and the outcomes are truthfully mind-blowing—URLs are getting listed in Google in underneath 2 minutes.

To see what’s occurring behind the scenes, I used Request Catcher to observe the exercise, and I caught a cell Googlebot hitting the URL nearly immediately:

Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5X Construct/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/147.0.7727.116 Cell Safari/537.36 (appropriate; Googlebot/2.1; +http://www.google.com/bot.html)

The software suppliers are making a really daring declare concerning their technique:

I’m a bit conflicted right here. Whereas the pace is unimaginable, Google’s official documentation sometimes states that the Indexing API is meant for pages with structured information for Job Posting or Broadcast Occasion. Nevertheless, this software is utilizing the urlNotificationsublish endpoint for traditional articles and weblog posts with zero points to this point.

I’ve a number of questions for the search engine optimization veterans right here:

1. Is utilizing this API for normal content material really “policy-compliant” as they declare, or is it a “grey hat” tactic that might result in a footprint?
2. Has anybody skilled de-indexing or penalties after utilizing this particular API technique on cash websites?
3. Technically talking, if the Googlebot go to is professional, how would Google distinguish between a pure crawl and one triggered by this API?

I’d love to listen to your insights or any long-term information you might need on this technique. Is that this the last word indexing resolution or a ticking time bomb?

Thanks upfront!
