In my experience of blogging I have found that authors tend to make the mistake of writing very long posts, then wonder why they have no time to update their blogs regularly.
The key thing to know when writing blogs is that 1. search engines are looking for keywords not how much you’ve written 2. people will get bored reading an article that is 500 or more words long.
Ideally a blog should be between 200 and 250 words with plenty of interesting content and keywords.
The keywords should be hyperlinked back to the appropriate categories for the search engines to pick up.
It is also important for your blog to remain interesting to encourage visitors to come back and read other articles.
This will in time encourage visitors and search engines to trust your website, resulting in a higher search engine position and more people visiting your website!
