Katrina,
The easiest way I know how to explain SEO is to think about how you would say to your girlfriend 'Hey look at the cool new xxxx' that i just finished making, and then use the xxxx as the basis for your title.
So on your
""Bridal Flower Crown, White and Cream, Woodland Wedding, Ivory Floral Hair Wreath, White Flower Festival Crown""
based on your title its difficult to tell whether or not you are selling a crown or a wreath. Are the flowers real? What kind of flowers are they?
An item is 'relevant' if its what a person is looking for. For example, you want to go out to the mall for dinner. So right now, the only potentially relevant restaurants are the ones at the mall. No others matter.
So your initial search would be 'restaurants in the mall in Hudson Falls'.
Then you decide that you want a burger. So if the restaurant in the mall doesn't serve at least one burger, its no longer relevant either.
Your search has now become 'restaurants in the mall in Hudson Falls that serve burgers'.
So now you've found the best burger joint in the mall and start looking at the menu. You decide that you want cheese on your burger so any burger that doesn't come with cheese is no longer relevant.
Your search has now become 'restaurants in the mall in Hudson Falls that serve burgers with cheese'.
And by the time you are done, you the customer will have the perfect burger.
All the other restaurants in town may have great food but their meals just aren't relevant.
