Passive income for the winter

Now that we are coming up on Thanksgiving and working our way into winter, the garden slows down.  That also means the income from anything growing on the farm slows down or outright stops.
We're still eating from the garden but we don't mind eating the tomatoes (because yes, we still have tomatoes growing) that have blemishes, or the turnips that are the size of a volleyball.  Those are products that while perfectly fine to eat, aren't as easy to work with for the average consumer.
Last week, I shared some information about getting involved in stock photography and this week I'm thinking more on how to turn a blog into income.
There are a lot of blogs out there already and it would be an easy thing to add some of the pictures I'm already taking for the stock photos, to the blog. That would be a very niche way to separate my blog from others.   It would take a lot of research into what is out there already and what is doing well, to determine what might be lacking.  At this point, I think other than basically being willing to start documenting from the ground up, the only other difference is geography.  I'm not sure of any others in the North Alabama/Southern Middle Tennessee area.  So we'd just have a different perspective.
Being so close to the state line also offers twice as much learning about rules and regulations.  All that can be shared in a blog, as well as the steps taken. But, this is only good if people can find your blog. One easy way is to pay to have the blog listed or actually get a domain name and real website.  Basically, if it can't show up in an internet search, it doesn't exist. This is one of those "takes money to make money" types of things.   This site, offers some nice things like tracking how many readers your page gets. It also offers "AdSense" which allows targeted ads to be in the blog, which can generate income.
Another way is to do a review or share a favorite brand or product.   Mention enough times how much a certain brand of fencing or trowel or whatever works for you and you can turn that into a link where if your bases buys through the link, you get a little kickback.
It all still goes back to marketing principles and how to get your name and product out there, even if your product is a blog.
