First things first, by the the time you’ve gotten to this stage, you’ll probably have an idea what your site is about, and what topics you aim to cover as well as what your keywords are.
depending on your strategy there are two approaches, if your writing to constantly update the blog then you want to write more news related articles and about subjects and topics that are in the news, link bait and topics that encourage readers to see your site as a news point, like a magazine.
Alternatively you can take the approach where you setup the blog as a website, providing fixed information, in this instance you’re looking at writing articles that won’t change often, such as instructions or tutorials.
You want to build up a group of keywords for the specific article you are writing, and for each article you want include those as well as the generic keywords for your site.
Keep the articales interesting and captivating, and on topic. Add images and if your article is for affiliate marketing then naturally you want it to be encouraging and enticing with plenty of call to actions that readers can respond to. Finally, keep articles around 200- 300 words, anything beyond that is heavy going for the reader.
