I put my search term words as a string for backend keywords. They aren't indexing

For my footrest product, I can't get the phrases "gaming laptop accessories" or "gamer gifts for men" to index. Are they too vague for my product? "Gaming equipment" got indexed. Thanks

I've opened several cases to get this violation resolved, but it keeps popping up, and wont allow me to make other listing changes until it's fixed. The researched the issue and said: "After reviewing your Bullet Points, I found several guideline violations. The first Bullet Point contains unverified health or medical claims. The second includes marketing story or personal narrative. The third makes comparative claims against competitors. The fourth uses the prohibited phrase 'eco-friendly'. But it only shows an error for me on the first bullet.

@Matt Atkins asked me to add a keyword that was having trouble indexing in the Search Terms, as a keyword tagged onto the end of a bullet point, and find out how fast it would index if I did that. It worked in under an hour!

I've been working on indexing more words for my listing, but I've noticed that sometimes words that are listed as indexed in Index Checker, aren't listed on Cerebro.
