I remember a few webcomics post at least a single update ahead on their own website to drive traffic there, and it's been quite successful from observation.
Extra incentive if your website offers uncensored updates too (trust me, I KNOW this from experience. I literally did not update my webcomic on Tapas in months and YET my most viewed update is the one with the uncensored panels... by a LANDSLIDE. I did not even advertise it at all lmao)
