user2869: Referring to question about How should “Rosario + Vampire” be tagged? I find similar case here about Kiss x sis, now it tagged kissxsis
Should we leave it like that or should we change it?

user1458: The current tag is not 100% accurate to begin with.
The official translated name would be Kiss×sis instead of Kissxsis. Following google trending  Kiss×sis Is a term only used in japan and would be bad for SEO.
Also I don't find this to be the same case as Rosario+vampire. As there it was mainly a issue about the fact that the + would split up the tag into 2 different tags, which is not the case here.
As for its current naming it will hit both Kissxsis and kiss x sis searching, broadening the SEO.
For kiss sis hits both kiss x kiss and sis x kiss. Which are both pretty common typo's on the series.
There for my suggestion would be maintaining its current tag for SEO, or changing it to kiss-x-sis as this also maintains SEO.
