There usually ins't much benefit to leveling a skill unless you can get it farily far along. For most servants' skills leveling to 4 barely gets you any additional effect over Lvl 1, and you don't even decrease the cooldown until you take it to 6. Not to mention that the mats needed for leveling skills can be hard to get, and costly to use. This is especially true of SSRs whose sheer stats make them tough to beat. You can farm embers from the daily and get even an SSR to around lvl 60 in one shot. It can take days of farming for some items to level up just one skill to lvl 6 if you haven't been hoarding the mats already.

Sklls can be critical on tough fights or if you've got a weak servant whose benefit is primarily in a powered up skill. But otherwise you're much better off holding off on leveling skills until you figure out which ones you'll really need for whatever role the servant serves in your team and you have enough to take the skill to 6 or even 9. Leveling up the servants just costs less and gets you more immediate impact.
