Organise your writing
So, you've got this idea for your next page or post, that you came across reading news, or going through the internet. Start researching more, as the more you read about it, the more points you will put together to write about in your post.
I am not at all suggesting that you should simply copy and paste from other sources. But whether you intend to state a fact or simply your view point, your aim is to be as accurate as possible, so as to increase your credibility with your readers, hence to attract more traffic in the long run.
And in turn, the more traffic you attract, the more SEOs are going to push your pages or posts to the top. So, it's an all win situation.
