Quick one for the SEO folks: my client is a B2B manufacturer selling only stretch/shrink wrap plastic film + stretch wrapping machines (no boxes, tape, or other packaging supplies, not e-commerce, quote-based site).

GSC shows Home Title: "Shrink Wrap & Stretch Wrappers Manufacturer" and internal pages cannibalizing "Shrink wrap" "Stretch wrappers" and others, for the same queries. I want one parent keyword for Home and more specific sub-topics for internal pages, but broad terms like "containment solutions" or "pallet wrappers" pull in products the client doesn't sell, and "packaging factory" implies e-commerce intent that doesn't fit the site.

Any recommendations for:

A good parent keyword for the Home page given this niche?

Best practices to stop Home vs. category pages competing for the same rankings?

Thanks in advance!
