The main thing I appear to be missing is keywords in my URL. How truly important is that in today's SEO world and how much time or ranking would be lost if I do not have control to change the external links to my website if I decided to migrate to a keyword relevant url?

I agree with Marcus - if you are creating new urls and articles - keyword rich urls can deliver some added value but are overall of lesser importance to other contributing page factors.

Hey, it's a nice thing to have, desirable for sure, but consider it something to do for new pages and articles rather than something you desperately want to change on existing content. I would always avoid changing page names if at all possible and where you are ticking 35 out of 36 boxes as above this is not going to bring big rewards.

An exact answer, would always depend on the specific keyword, page, case etc but as a general rule of thumb, I sincerely would not lose any sleep over this one!

Hope this helps!
