For some reason your sig didn't show up on the initial post.
I think the site looks fine. Here is some help on keywords.
Then here's an example of what to do on your product category pages.
Your candle page as an example. Get rid of your name in the meta title. Get rid of the word scents as no one will search for it so it's a wasted KW. Scented candle someone would search for but not candles and scents.

Pick 3 - 4 at most candle KW. They have to be words that are on the page to have any value in the title. They need to be candle types you actually carry too.
So use the words in the title then also work them into the description you have at the top of the page. Hopefully they are words that are in the product descriptions too.
This is not a great title and NOT the best KW, just making up a quick example for the title. "Scented unity, pillar and votive candles." So there I got 4 candle KW in but it still reads right to a person who's shopping for candles. Again I don't know anything about candles or what kind you carry, so just giving you a very rough idea.
Be sure to put whatever KW you use at the top of that page where the title Candles and Scents is now. That's an H1 font which is good. Then also again in the paragraph at the top of the page. Rewrite it in the paragraph so it sounds right to visitors. "If you are looking for the best price and selection of scented unity, pillar, votive candles and more, you are in the right place."
So the key is 1) picking the right KW 2) Matching - the KWs need to be in meta title, then either in bold or H1 at top of the page in the title and also in the body. Then you also need to have products that match the KW you choose so when the KW pulls the person in through the search engines, they can find that product.
Does that make sense?
