Welcome to the Q&A Forum

It really doesn't matter. Anchor text as a ranking factor is on it's way out as far as we can tell. I would call yourself whatever works best. If it makes sense to call your business Isle Paddle Boards, cool. But if you sell more than that, you might do something more broad.

When you link, just make sure you're describing the page and why people might want to visit it. If the story is about paddle boards, you might link to your paddle boards page with "check out [Isle Paddle Boards]" with what is in the brackets as the anchor text. Make sense?

Don't worry so much on what exact phrase to focus on. Does you page pertain to just stand up paddle boards? Or all paddle boards? Or are those the same thing? If they are the same (and I don't think so), then use the longer term.

First, don't worry so much about how much content is on the page. You should format your pages based on what works best for what the searcher is looking for. If there is demand for information on Biomass Industry types and there is enough content for a page, then create a separate page. If there isn't enough content for one of these pages, and it makes sense for the user to land on the more general page, do that.
