With Tapas now busting at the seams with 26,000+ creators, its really hard for them to promote any one creator because there's simply so many to promote! It's like a parent with 26,000 children. Who do you hug first?
Because there are so many creators, you really can't count on Tapas to highlight your series unless you're doing something out of the normal to get their attention. Ways to get their attention?
Create Tapas fliers to hand out or post around campus. Put your series in the thumbnails or copy. Take a picture with your smart phone. Send the picture to josh at tapasmedia.co. There's a pretty good chance that they will Tweet that image or if you Tweet it they will reTweet. The Tapas Twitter account has 11.3K followers. It's a good way to get some interest in your series.
Cosplay as a character from your series or from another favorite series of yours. Halloween is right around the corner and there's always a con going on somewhere it seems. Take a photo and share it to social media or toss it towards Josh. If you cosplay someone else's series they may promote your on their social media so you get both them and Tapas promoting you.
Create Tapas fan art like Mr. Tapamon and push it out to Tumblr, DeviantArt, Facebook, and Twitter.
Have a Tapas table in your local con's Artist Alley. Some AA tables go for as little as $25! Maybe see if there are any other series that would like to pitch in $20 and you can pool the money to get a table at a larger con to promote all the series there. Take pictures of you being an ambassador for Tapas and staff will likely take notice. Who doesn't like someone who is self motivated?
Besides everything you do to promote Tapas doesn't only help just you but every other creator because most readers read a lot of series! If we saw you "fighting the good fight for the benefit of all" we'd be certain to reTweet you to our followers.
Consider adding Project Wonderful to your site and/or using Project Wonderful to promote your series. Some of the ads we run are as little as $.005/click because we keep using non-expiring low bids (in case there is a lapse in more expensive ads we can get a spot for 1/2 to 1/6th the cost!) and have excellent targeting of potential readers who we think would like to read our series. Even more awesome, if your bid is the only bid, then your ad will cost you $0! Plus the money you spend there goes towards supporting other webcomic creators, so the money is going to a good place vs. some huge corporation.
If you have $1/day to spare, consider spending it on TopWebComic's $1 day sponsorship. It gets you a small ad box on the site. Readers actively pay attention to those boxes because they want to see and support series. The click rate is such that it's about $.035/click for us. We've also purchased the much more expensive banners on the site... which everyone just ignores.
Remember, webcomics require a 5 year plan. Update 2 or 3 times a week, but no more. Update 1 page at a time, but no more. Get your subscribers in the habit of coming to your series, but don't give too much away too quickly. Build anticipation and word of mouth. All those comments and likes you get with each one page update (vs. a larger update) builds your numbers with the Tapas algorithm and you may find yourself in Trending.
