I have just seen an article in EZA that is slightly under 3,000 words. Yes, you read that right - 3 THOUSAND words. I even checked it again to make sure I'd read the word count correctly.
In all honesty I didn't read the entire article as I prefer shorter ones. Had it been written in a fashion of story-telling it might have captured my attention and compelled me to read, however this was not ones of those.
Whenever I write articles the number of words used is dependent on what I am using the article for. When I submit to EZA or other directories the finished article is usually between about 400-500 words. If it is for my blog that's a different story.
If nothing else, it got me thinking about my own writing. An 'average' length of article that I write is about 500 words - give or take a 100. For ones that are far longer than that then I would break them down into 2 shorter ones.
I'd be interested to hear what you have to say on length of articles and how long is too long?
