Welcome to the Q&A Forum

These are testimonials that our staff have collected themselves, so I'm unsure about using a block quote and citing a source, since these testimonials are original content, not references from another website. I just need to place the quote, the author's name, and, in some cases, the author's city. Any recommendations?

I'm seeing a lot of 404 errors with slugs related to cryptocurrency (not my website's industry at all). We've never created pages remotely similar, but I see a lot of 404 errors with keywords like "bitcoin" and "litecoin". Any recommendations on what to do about this? Another keyword is "yelz". It usually presents like .../yelz/-ripper-vs-steller/ or .../bitcoin-vs-litecoin/. I don't really even have the time to fix all the legitimate 404 errors, let alone these mysterious requests. Any advice is appreciated.

I'm working on redesigning our website. One of the content types has a main archive page (/success-stories) containing all of the success stories (written by graduates of our program). Because we plan to have success stories for other people (non-graduates), I'm using category hierarchies (/success-stories/graduates and success-stories/nonprofits, for example). It will go one level deeper to organize graduates by graduation year (/success-stories/graduates/%year%). I think this will work out well. However, we won't have non-graduate success stories for a little while, probably at least a few weeks, which means that /success-stories and /.../graduates indices will contain the same content for a while. So my question is this: Will it hurt to use a canonical tag that points to /success-stories/graduates as the authority until the main archive page contains more than just graduates? Or would it be better to use a 302 redirect from /success-stories to /.../graduates until more diverse content is added?
