I've been a creator on Tapastic for about four months now, with two-ish series under my belt, and I've realized that there are a lot of things to keep in mind when you start and how you keep a following:
Promise to upload on certain days, and do your best to deliver.
This allows readers to have not only an expectation for your comic, but a sort of subscriber-creator loyalty. Promise to upload a certain amount of times a week, and if you don't deliver, don't worry. This site is very forgiving.
Reply to most of your comments.
When I say "most", I mean not "all". Tapastic says you should be involved in your comic's comment section, and I agree. However, to reply to every last thing can bring the thought of desperation to the readers, and you don't want that. There's a balance of how much you should reply, like towards questions or maybe the most inventive comments.
Upload at proper times.
Unless you promise to upload every day like some comics do, upload one comic page at a time every few days. Never upload twenty all at once for that can overwhelm readers. What also works is that if you are ahead of schedule, move the publishing date of your comic to later on, giving you a bit of time to keep working and the readers something to look forward to.
Be creative and original.
Despite the fact that many strips here on Tapastic, especially the more popular ones, seem to have a similar sense of humor, don't let that stop you from doing your own thing. Keep your jokes and story-lines original, and even if it's a niche audience, there's no doubt that someone out there might like your comic. If you enjoy how your comic looks, don't change it unless you really want to.
Be involved in other comics.
I don't really mean collaborations, although those sometimes help. What I really mean is commenting intelligent, meaningful or just funny stuff on more popular comics, but also being respectful not to shamelessly plug your comic on their wall or comment section. Just being there helps other readers to see your sense of humor or personality, and if they enjoy what you say, they just might go and see if you have your own comic strip full of it.
Ask for a bit of feedback.
That little description section is great to get readers involved. Ask a question that adds to your comic to spark a conversation, or perhaps ask for your current subs to help share your comic on other sites. Also, you can host contests like caption contests, funniest comment contests, or fan-art contests if your subs are creators as well.
Find your niche.
If you have any amount of subscribers, keep practicing with your current skills and style, and stick with it. If you don't want to keep doing it, then do whatever you want. It's your comic. But then keep working hard at it so you find your spot on the shelf. Even if its just ten subscribers, those ten are only the beginning.
Help other creators struggling to find their place.
Many new series never get out of the low tens for subscribers. If you have escaped from that hole, look for others out there who might need a helping hand. Even if you haven't received this kind of help, you can always give it to others to start the cycle. You can ask for mutual subscriptions and start collaborations, shout-outs, guest comic spots, and other things that might not only help them, but can encourage them to keep moving forward and do the same for other missed series.
Make sure your comic is readable.
Reformatting your comic slightly to fit a down-scrolling fanbase can be hard, but always doable. If your text can't be read, choose a different font or a bigger size for your font. If it's right to left, make sure your readers know that before they even start reading it. Spacing out your comic a little more than you think and cleaning up your lines also helps.
Be involved in the forums.
Of course, if you're reading this, it's likely you already have an idea. If you are involved in conversations here at the forum, you just might create some interest in your comic. To shamelessly plug your comic is fine around here. Everyone does it, just be polite when and where you do it. Make interesting posts as well. Introducing your comic or maybe just asking a question or topic is great. It'll get more people interested in you, and if they're interested in you, they might be interested in your comic. And even if you're suddenly an overnight hit, you should do your best to stay around and contribute your thoughts on the forums as well. This place is for everyone, not just the low tier.
Don't expect to be an overnight success.
If you are familiar with Tapastic, either if you're a reader or a creator, you'll notice that there are a lot of new series suddenly appearing and receiving tons of praise. You may think while looking at the "Staff picks" section (and many of us have), "I could do that too". The problem is that, unless you're lucky, you will most likely never be featured there. The thing is, most of the new series that get noticed are from existing authors, either from Tapastic or other sites like InkBlazers or Tumblr, who might already have a following. And then those fans carry over. For Tapastic, this is a great opportunity for more accounts, but not always for new creators solely on Tapastic.
Don't expect to get paid.
Another thing new artists may notice going in is that there is a possibility to get paid here on Tapastic. Some series get minor amounts, but others more so. In a lot of ways, it's a great opportunity for those in the art and comic making industry to have an income. However, Tapastic's Support Program does not directly come from the Staff (at least not always). Instead it comes from the fans that follow you. So it's logical to only become a part of the program after you have a large enough following, say a few thousand subscribers. Otherwise, be patient.
Stay committed.
Now if you've really wondered how some creators could get such high views, high subscribers, and be paid in such high amounts, here's the thing to know: a lot of those creators have been around for a long time. Longer than the overnight success-ors could ever imagine. They started from the ground up and only through time and effort have they ever gotten this far. But thankfully Tapastic is still a "young" site. It doesn't have the millions of users like YouTube, but it's getting its foothold on the internet and it could be the place where you start out, leading to much bigger things. If you stick with Tapastic, Tapastic will stick with you.
