Welcome to the Q&A Forum

Update: I checked the rel=next/prev tags in Screaming Frog and they are not implemented correctly. The homepage is identified in all rel=next/prev tags. Not good.

I'm thinking I'll scrap my rel=next/prev efforts and try a view all option with a canonical tag.

It does not appear to be working from the pagination testing tool. I get a "previous and next URL does not link back" message.

I do believe the problem involves these links being dynamically created, possibly with Javascript. The reason I think this is causing the problem is because when I view the code in Chrome via "View Page Source" the links are empty (href=""); however, when I view the code in the inspector (Developer Tools) the links appear and are correct.

Can I validate link next and prev markup for paginated content?

For example, I would like to optimize a title tag with two keyword phrases: industrial supply and electrical supply. Instead of creating the title tag Industrial Supply and Electrical Supply, which sounds unnatural, would I get the same SEO benefit using Industrial and Electrical Supply?
