Okay, you had a robo-blog. That’s fine. Nothing wrong with that. In fact, I’m appreciative for some of those posts and blogs you pointed out to me. You apologized profusely, though I don’t there’s a need to apologize for a robo-blog per se.
However, since then your robo-blogs have gotten worse. The one associated with 3D-Printer-Parts.com, which links back to your site, is collecting anything and everything with the words “made, make, printer, 3d, 3-d” et cetera. Oh, but that’s not the worst part.
Botmill is stealing the entire content of other people’s works and not providing any attribution. That link is to one of my own posts (and not a particularly interesting one) copied whole cloth and posted in your own blog.
Make up your mind – do you want to be a blog aggregator or sell robot parts? There are tons of aggregators out there. Not many are very good. The ones that are have a real person picking and choosing. The robo-blogs are basically packed with irrelevant or useless content. Turn off the robo-blog and drop the fake secondary sites. Rather than stealing the content of potential customers, why not write some of your own content. How about posting some information about your own products? Or some innovations of your own? Stolen content doesn’t help you with customers, hurts your Google PageRank, and actually causes ill will.
Why not take a page from MakerBot and MakerGear? Have a contest, give some stuff away, write some interesting things, ask them for help, show them you care, involve your customers, and form a community.
