Hello, how can install: Ahrefs, Applebot, Bing, Google, MegaIndex, Semrush, UptimeRobot, Yandex,?

I have installed only Google, Bing and Yandex.

Thanks

Not sure what you mean by install.

You define bots in the ACP - Configuration.  A quick search gave me the user agent string of all the bots in your list.

To confirm, this doesn't do anything other than show them as those bots on the who's online list - there's no benefit to SEO by adding them or anything.
