Welcome to the Q&A Forum

We have 155 podcasts and in many we have affiliate links to Amazon. But I recently found out that one of the two products we are promoting is no longer available. I now have to fix many podcast descriptions. My thought is maybe to build a link like: financiallysimple.com/camera and 301 it to the Amazon product.  That way if the product changes, I simply change where the 301 points. Simple. BUT my question is does that bouncing people offsite immediately hurt us? Are there any other options that will accomplish the same goal?
Thanks!

Our theme adds a class to our site's H1s. For example:
Our front page: ... The blog: ... As a result, Moz is not seeing the keyword in titles when checking using Page Optimization. The theme developer says there is no setting to turn off in order to test this. 
My question is, is this a true issue that is hurting our site or is Moz simply not finding it because it only looks for ? Are there other options for troubleshooting this potential issue? Thanks for your future answers.

I have recently taken over the maintenance/redesign of our website and after setting up Moz I see many errors:
Duplicate content
Missing descriptions
Duplicate titles
etc. All are related to blog categories and tags. My questions are: are these errors hurting us? Should I simply remove tags/categories from the sitemaps or bite the bullet and create content for every single category page? Our site is https://financiallysimple.com/ and we are using Yoast plugin in Wordpress  (if that helps)
