No surprise there. It is very common for startups or small to mid-sized companies to start a blog as a companion for their product, with articles of the schema "Very broad description of some common problem/need, followed by very specific guides - often times even step-by-step - on how to use their product to deal with said problem/need."

It widens the spectrum of keywords that they can be found with a lot and thereby increases traffic to their main page and product.

I've run into these so often. I'll be searching for a solution to a problem and I notice a "tutorial" but it on the site of a product that's name implies it is related to "fixing" the problem. And yep, as soon as I start reading the tutorial I can see they are going to say to use their product and explain how to use it. It gets rather annoying seeing these when I know there are free solutions.
