Visitors to websites generally want information, but they do not like to read it on screen. Our eyes are better equipped to read printed text than the lower resolution typeface of web pages.
Internet users do not like to have their time wasted by lengthy explanations. Generally, they won’t sit and read line after line of text to find the paragraph they want.
Using a few simple techniques will make your web text friendlier and easier to digest.
Start by finding out who your audience is. If it helps, invent or get to know one member of that audience and write specifically to them. Having your target reader in mind will make your writing more personal and will help you to organise information to better suit their needs.
Next, plan the structure of your page or pages. Think about whether your target reader would find it logical. Would they know how to find the information they want straight away?

All the more reason to put the most important information at the top and avoid long pages. If you need to have a long page, make sure to include anchors so that all the information is easily accessible.
Make sure that you tell people about a download, so they can decide if they want to wait for it or not. Include information on file type, name, size and estimated download time if more than a few seconds.
People expect the information they read on a website to be current. Unless you are sure you'll have the time to update your pages, avoid phrases like 'this year', 'last month', 'next conference', 'recently'. They will fall out of date and make no sense.
Never underestimate the confusion, panic and dismay that instructions can cause.
The problem is obvious: we know exactly how to do the thing we’re trying to explain.
think it’s perfectly simple. But we are not who the instructions are aimed at. Instructions on the internet can be baffling. Avoid confusion with these tips:
These, and the plain English guidelines, will help you to create a friendly and informative tone in your web writing. If you still feel that your text is too cold, remember that it's okay to make moderate use of abbreviations like 'it's' and informal figurative language like 'in a nutshell'.
