Choose the target audience for your online children's book. Will it be a toddler's picture book, an early reader for kindergartners, or a lengthy chapter book for preteens or older children? Research information about what types of words and sentence structures to use for your intended reader base. In order for children to read, understand and enjoy the book you write online, you must write to their skill level.
Plan your children's book before writing it by creating an outline or notes in a word processing program. Information should include the characters' names and species (if you are using animals as characters), basic information about their lives, and what they want in the story. Choosing a theme or moral for the story is also a good idea. Many children's books include a lesson in manners, morals or something educational in some way.
Write the story. Remember to write it from the child or young animal's point of view. This will help your reader associate with the character more closely. Children's books usually focus on a simple problem that any child may face and the solution to that problem. Always write a happy ending.
Edit the text so that it is concise and correct. Of course, fix spelling and grammatical errors first. You can use the computer program's spell checker to help. Then, cut down the word count by using descriptive nouns and verbs and limited adjectives and adverbs. Include nothing in the final version that does not contribute to the story.
Draw or find illustrations for your book. You can also hire an artist to do the work for you. Using stock photography or clip art is another option for Internet-based books. Format the text and pictures in a file so that each page has an illustration and the accompanying text. Depending on the age range of your intended readers, do not put many words on each page. In general, the younger the child, the more pictures you should have.
Post the children's book online by creating a website or a blog where it can be displayed. Each page of the book could be a separate page on the site, and kids can read along by clicking a "next page" button. Upload the pages as graphics or use large-font text for the story with added illustration graphics. Create a new website or blog for each children's book you write, or post them all together in an online collection.
