Ok, this is tricky to get right and will be minimal results at best, due to the website types involved eg: Sole Traders linking to Traders. Trader shop websites will naturally get less links than a blog for instance, well, the blog has content, obvious right, so content creation is where everyone should be going and I'm shocked so few still hold the likes of Instagram, over a well stocked blog full of rich content, after all blogging is the 3rd biggest form of promotion today. People are wasting time posting on Instagram way too much - don't give away your valuable content to someone else, when it should be working for you. Instagram is an American photo and video sharing service - NOT a blog, it's the wrong tool for self-promotion where it's getting rewarded for your content - yours! People are looking for advice, tips, expertise to tap into, so why aren't companies giving it to them. Well, if they built content instead of trying to beg for links, they can place themselves as the experts, and then other sites will automatically link out to the expert content and recommend it. This is not a difficult thing - it's just hard work. People love content - it's a natural process, since the web is full of it, so start writing for results.
