Question about how-to video

I made a video in the spring, how to ice a cake and posted it on our business FB page. There is a *discreet* website at the end as well as 'find us on Tweeter and FB'. I'm wondering if I could/should upload this same video for a cake decorating Instructable, or will people consider it  spammy?  I can go in and edit it out, but that would take 10 minutes away from my next potential Instructable, lol!

Would love some opinions... :) Thanks!
