Writing for the web is a totally different experience from writing for the print media, whether we discuss here essays, press releases, marketing content, technical material, or journalistic articles. The core difference between the media, lie in the properties of the media as electronic dynamic - webbish, vs. static and portable - print on paper.
Naturally, the characteristics of each medium and its limitations impose some rules on the writer and the designer of the text and the visual image. Such characteristics also dictate some methods of work, styles, and tools. The two media, online and print, also address the readers, who likewise live by the standards of the media, in a very different fashion.
The printed format is usually limited by size, and thus usually contains more text, describing and explaining the theme, with little to no visuals. Whereas the web post, embedded with hyperlinks, allows the writer to compose a concise description, and demonstrate the idea with a strong visual image, that can spare thousand words and add significant impact.
Nonetheless, hyperlinks do not limit the text, as much as they serve as content dividers, or organizing utilities. Through using hyperlinks, the text can be better divided into topics, sub topics, and sub sections. The division is thus, modular and pretty much thematic. The readers are active in selecting the content to read, and they are the ones to decide on the reading order, not the writer. In this way, the presented theme can be more understandable—compared with the printed text that is usually used to convey all the bunch of information in a linear fashion.
All the more, a web release requires from the writer a very different writing style—more succinct topical coverage that can fit the hyperlink medium and text division on screen. Such a presentation requires relatively short paragraphs, with some space between them. Each paragraph is “standalone” in the sense that it does not take for granted what other paragraphs the readers have read before; for readers might not necessarily opt to read all the paragraphs sequentially.
Thus writing for the web and accompanying visual design must be modular in the sense that any part may be reached from elsewhere on the site, and that includes the visual component. The visual is another important component of websites, compared with the printed medium. Visuals may appear in full size, or as thumbnails, and be processed (or manipulated), as well as realistic. Visuals have a strong impact on the impression of the site, the company, the product, the service, and the profile. The printed media cannot and do not stress the visual, usually due to size limitations and cost related issues; whereas websites can just present the image with no printing overhead and cost-related constrains.
One of the most prominent advantages of web writing compared with print writing is the interactivity with the readers that the media imparts. Allowing the readers/users to select options, vote, fill in info, submit content—affects the writing style and the visual presentation a great deal. That is, wherever the readers become involved in the content and the features that the site promotes—the text changes according to his selection, and sometimes also dynamically during runtime! Such a thing is impossible using static print.
Writing for the web and for the print requires different tools for handling text and images. The printed medium usually uses desktop editing tools, such as MS Word, and desktop publishing tools such as Freehand, InDesign, and Illustrator or Photoshop for image treatment; while web design can be created with different writing and editing tools (similar to print) or use Photoshop for image treatment, however with no need to page and layout the text or format it physically on paper.
Despite the great added values of web writing over print writing, print writing is still considered a more "formal and official" choice, and therefore is the current standard in “serious” publications of books, scientific articles, academic essays, and legal publications. The printed result is permanent, less suspect to changes and amendments, and not less important, portable. Whereas, web text and visuals are more dynamic, changeable, updateable, durable for life, and more and more portable as well, thanks to handheld mobile devices, notebook PCs, PDAs, i-Phones, i-Pads and the like.
