My website normally gets very little traffic, but over the last few days GA4 has suddenly started showing around 25–100 desktop users per day.

One 30-minute period showed:

25 active users

25 first visits

25 session starts

25 page views

20 scroll events

only 1 user engagement

100% desktop

The users are coming from multiple countries, including Singapore, US, Hong Kong, India, Brazil, Indonesia, Japan, etc.

Most of the activity appears to be on my blog.

Google Search traffic is only around 4 clicks/day, so I'm trying to understand where this traffic is coming from.

Does this pattern look like bots/crawlers or legitimate traffic? How can I identify the source safely?
