I have a client who is creating many (over 70 so far) blank webpages and redirecting them all to another, single page. They're doing this as a method to turn tracking URLs with custom campaign parameters into shortened URLs for printed materials.
Unfortunately, I can't provide links due to privacy but it goes like this:
They have a real page with analytics tracking code:
Then they create a blank page to print on flyers:
(in this instance the blank page title is 'AADR2016').
Then they 301 redirect the blank page to the real page with analytics tracking code.
Now, this seems TERRIBLE and like they should just use Bitly. But, I can't think of specific reasons to tell them if/why it's bad. I would imagine it screws up XML sitemaps and SEO, to name a few, but I'm hoping someone can steer me to actual issues (or non-issues) this might cause?
