Strange Ranking Fluctuations After Publishing

I recently published a new post on my site, and it initially settled at position 33 for my target keyword. For three days, it remained steady there. However, when I checked again today (Monday), it completely disappeared from the rankings, not even appearing in the first 150 results. After a while, I checked again, and it was back at position 33. I asked ChatGPT about this, and it mentioned something about dynamic ranking, where Google’s results fluctuate below position 30. Has anyone experienced something like this? Does this dynamic fluctuation really happen often? Is there something called dynamic ranking? **Do you think I should be worried about this?** Additional details: * My site is **1 month old**, with a **new domain**. * I’ve built a few **backlinks** (currently working on more), but they are **not earned**—just created. * While writing the content, I took help from ChatGPT and spent **4 hours** doing manual research. * The post ranking at position 33 had **no backlinks**—those backlinks I have are only pointing to my site’s **main page** or **service page**.
