A lot of articles I read online are way too long and complicated to have their intended effect. If you’re writing something for your website aimed at ranking for a specific question, stick to providing the answer. Yes, an article aimed at a competitive search will probably need to be more substantial than the rest. But if you’re targeting something which few (or no) others have targeted, it really doesn’t matter. Look at how we cleaned up on the search “How do I apply a chrome pre-treatment to aluminium?” for Stowlin Croftshaw in Leicester. The article has no real content at all – it just strongly links to product pages which are relevant. Sure, that’s an extreme example which I wouldn’t necessarily guarantee will work. But Google is getting better and better at identifying what answers the question and what doesn’t. Articles don’t always need to be weighty and academic. Just make your point.
