I like reddit a lot, I get more upvotes there than here, sometimes even more than on instagram, but my content is gag a day(weekly) between 3 to 6 panels, so I can post the whole thing in a single post.
But it can be random, I post all my comics there and sometimes I get 3 likes and other times few hundreds, and always gets more traction on r/comics than on r/webcomics
The thing that I have notice with reddit, is that is just difficult to make the people get out of there, the post have to be really good or interesting to make them click on a link other than to imgur, and not sure if you can post multiple images at once.
so, If your goal is to bring people from there to here, not sure on how to accomplish that. but If you want to create a fanbase there as well, I think your gonna have to find a way to post the whole thing, but take this with a grain of salt, since that's what I have seen in the 3+ months I've been there, posting twice a week.
Another thing is that Upvoting and following is anonymous, so I guess the only way to people know you're in there will be commenting on other people posts, but I don't think people pay too much attention to that. again, from what I've experienced.
