Since a large number of E-commerce and Static website requires good amount of English Composition- The process can be frustrating since the objective of writing has no fixed goal.

Are we writing to create an online marketing campaign? Are we trying to communicate?
What is our goal and strategy? Are we creating a Public Relations material that is supposed to create a buzz like strong German Schnapps or the public relations will be low key like warm Glue-Wine of Scandinavian Christmas.
Are we just trying to create some ineffective web pages with a lot of CSS so that we can demonstrate our technical savvy?

In a more technical sense, Are we substantiating an argument? Using persuasion and compare and contrast to establish a point. Are we just trying to educate some factual information? Who is our target audience? Why such person be interested in our website?
Does the end user needs to be entertained? excited? provoked? educated?

Some how the short answer seems to all the above- and that makes it difficult.

I have found a solution. A new book on web content design seems to be immensely practical and useful. I am reading it , right now-Killer Web Content- Garry McGovern . I highly suggest this book to any one involved in web design and content creation. Also try the letting go words[4]. I use letting go words of Redish in all my website works.
