It feels odd writing a preface for an article this short, but what the hell. Anyway, these are some things that I wish that I had known when I started out. The existence of this "how-to" should in no way lead anyone to infer that I think that I am a top tier Literotica writer. I don't. What I do believe is that I'm better now than I was when I started.
Advice For New Writers
Deal With It
You're going to receive critical comments. Some will be valuable and without malice. Learn from them. Some will be baffling. Use these to remind yourself that the readership of Literotica is both wide and deep. You're going to run into people who aren't the best at expressing themselves. Some will be pure bile. It's inevitable. Go into the experience with that knowledge.
I'm sure that over the years I've posted comments that covered all three of those categories. I've tried to be helpful. I've certainly failed to get my point across. There have been times when I've been a dick.
Develop a thick skin. You're going to need it.
How Long?
A Literotica page is roughly 3500 words. If you are trying to figure out how long your story is going to be, that's a good rule of thumb. Dialogue heavy stories will have fewer words per page.
How long should your story be? There is no set length. Some people will swear by a three page optimal and a four-page allowable. On the other hand, many stories in the Hall of Fame exceed that dramatically.
What about posting chapters separately? One page chapters will frustrate readers. Don't do it. Also, you may want to consider having the entirety of your story written before posting any chapters.
Getting Help
In my opinion, beta-readers and basic grammar editors are of equal importance. If you happen to luck into an editor who can also offer feedback on characterization, story architecture, and plotting, you've struck gold.
Anyone can be a beta-reader. If you respect their opinions, see if they would be willing. Keep in mind that friends and family will often be overly positive. Critique Corner (Google it) is an excellent resource for finding beta-readers. You may want to ask people who Favorited your first story to beta-read your next. They also have a forum for beta-readers on GoodReads. The people that reach out to you through the Literotica email system and insightful commenters may be your best resource.
Finding an editor is difficult. Finding an excellent editor is exponentially more difficult. I can't self-edit. I'm atrocious and abysmally lacking in the editing skillset. Because of that, I'm tremendously grateful to the people that have been kind enough to edit my writing.
Use the editor's forum on the Literotica Bulletin Board. It's not going to be easy to get someone to respond to you. Be persistent. Ask for recommendations from writers on Lit that you admire. If worse comes to worst, you can pay someone to edit your work. Fiverr has reasonable rates.
If you do decide to go the self-edit route, consider using a free automated service like Grammarly (Google it) or the Spelling and Grammar function of Word. They are both far from perfect, but it might help as a last resort.
Pulling in Readers
There are a few things to consider here. The first is the genre you are writing in and where you are placing your story. I'm not kink-shaming, but if you are writing cuck or humiliation stories, put them in Fetish, not Loving Wives. The readership in one will be welcoming, the readership in the other will be hostile. [Editor's Note: stories of swinging and partner sharing DO belong in Loving Wives, as that is the purpose of the category per the category description.]
Establish a conflict and dialogue as early as possible. Conflict hooks the reader and dialogue helps with immediacy. Don't time hop. No one is interested in going from a guy cheating on his wife in paragraph A to the subsequent ten paragraphs being about his childhood, teenage years, college, first years on the job, and his wedding day.
If it's not necessary for the plot, excise it.
Answer emails. Update your bio information. Both actions will help you develop a dedicated readership.
Getting Better
To reiterate what I said earlier, learn from your critiques. Even if they are couched in negativity, some comments offer sound advice.
Try to learn from the authors you admire. What do they do that you enjoy?
Work on dialogue. It should 'sound' the same as a conversation you might overhear at Starbucks. Read it aloud to yourself.
