FIRST
You must choose a topic. There's no point starting to write a website if there's no actual topic that you are covering- you will simply fall into the trap of writing absolute nonsense that no one cares about. Stuck for ideas? Pick something that interests or intrigues you, or something you know a lot about. It might be cheese, it might be wine, it might be films; whatever you want to write about.
SECOND
Pick an audience. This could be an age group, a gender or a group of people who have similar interests/beliefs. Audience is a very important part of what and how you will write. There's no point writing like a human thesaurus if you're aiming at primary school age children, or writing for children if you're writing for the educated over 60s. Getting your audience right is key for a successful website as without an intended audience you will just be floundering around in a sea of people who don't care about, or don't understand, your website.
THIRD
Layout is important! This involves the graphology of your website- the font, the colours, whether or not you use pictures. If you're writing for women, you may want to use stereo-typically female colours such as light pinks and pale blues. If you're writing about cars, you're intended audience is likely to be men, so think blues, blacks and greys. Generally, the use of pictures is expected, even if you're not giving over your blog to them entirely. A clean, crisp image adds a lot of interest to your blogs and breaks up the text.
FINALLY
The text you upload must be relevant, grammatically correct with no spelling errors and not too long. Texts full of errors strike readers as unprofessional and irritating and they are unlikely to return to your webpage. Also, long chunks of texts are boring so try to break them up with
- Bullet points (see?)
- Pictures
- Headings
- Hyperlinks
