Keywords and google shopping
i am new to shopping campaigns and I want to understand how google determines which products to show based on a keyword. In other posts I have seen product title and description being the most important ones.
How about product category? I have fidget spinners and I am listing them under Toys & Games > Toys > Activity Toys > Spinning Tops, but i have seen that my competitors are using Sporting Goods->Exercise&Fitness->Hand Exercisers. I don't think this is relavant but since all the competitors use that category I have a doubt.
Also how can I make use of the custom fields, I have put some tags there but it is not clear how I can use them.

shopping-ads do not use keywords.
results in the shopping-ad auctions are mainly
determined by the bid and quality related factors.
generally, there are only two ways to improve performance --
increase the bid or improve quality.
yes, a primary determinant of relevancy is the quality of the title;
title should simply name the exact physical item using standard text --
a best-practice is to include the physical item's characteristics,
product-name, brand, and specific item details, within the first
70 or so characters -- although all 150 characters will be used
for indexing and search relevancy.
most all other visible attributes may help directly influence quality --
such as description, product_type, google_product_category, and
especially any global-trade-data (brand, gtin, mpn) that is submitted;
global-trade-data must be assigned by the manufacturer -- not merchants.
other attributes may also influence quality --
for example, any submitted or set shipping
must be accurate and valid for the item;
for example, the price is a critical factor;
for example, image quality is also a factor.
both google_product_category and product_type attributes are used to:
(a) help google determine which attributes are required for the type of item;
(b) segment items in a shopping-campaign to create effective bid-strategies;
(c) help google find a specific physical item during searches
on google-shopping and for grouping relevant shopping-ads.
all three uses should be taken into account when deciding on category values.
google_product_category requires an exact google-defined value
that is relevant with respect to the physical inventory item;
product_type may use any set of > breadcrumb categories
that are relevant with respect to the physical item.
there is no guarantee that google will use submitted
category values within any google-shopping results.
custom_label_ attributes are mainly used to create more abstract
bid-strategies -- such as bidding lower on low-margin items and
higher on high-margin or seasonal sets of items; google does not
use these directly for indexing, ad-search, keywords, or quality.
a best-practice is to measure results before, during, and after,
any change to any submitted (feed) data or the campaign --
while carefully monitoring the overall shopping-campaign.

My understanding is that price and title are the key factors. But there are many others, as Celebird has pointed out.
Usually there is only one category that is a good fit for a product, so this question is unusual.
I have experimented with changing categories of products and seen no difference in the results.
If the product has a GTIN/MPN/Brand then the category should be irrelevant. Without those, the category might help Google determine which other products it is the same/similar to.
The custom fields are to help you group different products in your campaign.
