I won't go into excruciating detail since I don't wanna type out that much but basically pixiv is a Japanese art posting website and one of its best features, once again, in my opinion, is the tagging system. It's quite good and beyond tags for specific characters or series, or just original stuff as well, there's tags to describe the art or the character/setting of it, like the style or certain traits present in the art. An important detail that I should mention is that since pixiv is a Japanese website most of the tags are in Japanese, but at the same time most of the tags are translated. So for example if I search up "poke" the first suggestion is the tag in Japanese for pokemon with the translation underneath. This also applies to the tags under the art itself.

Also when you're searching you can have the filter so it will either search exactly the tag as you wrote it, or you can have it search for tags that have what you wrote included within it. This is especially useful because certain artworks will have a tag that usually follows the format of "[series][numbers]users入り" which basically is for more popular works, by that I mean anything over 100 bookmarks, that the OP can add later. It's quite useful when you wanna find more popular artworks without needing pixiv premium, more on that later, by just having "users" as a tag when you're searching via tag partial match. You can also filter by time, i.e. only seeing stuff from between one date and another.

At least on the app, whenever you "like" an artwork by pressing the little heart button, it'll get saved in your bookmarks page. Long pressing on it will let you be able to set the bookmark to private or to add tags to the bookmark which will let you filter by it on your bookmarks page. Do note though, that you can't search by the tags already on the artwork via bookmarks, without certain browser extensions on desktop.

There's also an option to toggle on/off R18 work in the settings

Of course pixiv ain't all good either and has its fair share of issues. There are many options that are limited to being solely on pixiv premium, which is the pixiv subscription service. Examples include: being able to sort by most popular, seeing your browsing history, being able to block more than one user/person, and similar things.

As mentioned before unless you yourself out the tag you can't actually search up by work tags in the bookmarks page.

Pixiv also lacks the ability to be able to share/retweet/reblog something which may hinder the amount of attention an artworks gets.

Also it's terribly unfortunate, but pixiv allows ai-generated stuff. However they are marked as such and you also have the option to filter them out entirely. This of course only applies if the original uploader marked it as such but in my experience it seems to be fine.

All of this is based on my own experiences, which is mainly as an art browser and less of an uploader so your mileage may vary.
