Pet Supplies Plus sits at the top of Valvoline's neighbor set at 0.86 — not another auto service brand — and that cross-kind opening sets the tone for a broadly distributed similarity graph with no single dominant cluster. Similarity here measures how closely two entities' audiences resemble each other in composition; a score of 0.86 means the audiences of Valvoline and Pet Supplies Plus look nearly identical in shape, regardless of what either sells.

The top 10 neighbors span five distinct subcategories: Pet Supplies and Services (0.86), Automotive Parts and Accessories (Tire Discounters, 0.83), Hobbies Gifts and Crafts (Jo-Ann Fabric and Craft Stores, 0.83), General Apparel (Duluth Trading, 0.81), Sports Leagues (Minor League Baseball, 0.81), Department Stores (Kohl's, 0.81), QSR (Red Robin, 0.81), Thrift Stores (Once Upon a Child, 0.80 and Plato's Closet, 0.80), and Casual Dining (Friendly's, 0.79). Only one neighbor — Tire Discounters — shares Valvoline's broader Automotive category, and none shares its Maintenance and Repair Services subcategory. The audience shape here is defined not by automotive affinity but by a mainstream, value-oriented, everyday-errand profile that cuts across retail, dining, and leisure.

The breadth of this neighbor set — retail crafts, thrift stores, casual dining, pet supplies, and minor league sports all scoring above 0.80 — points to an audience whose shape is defined by wide accessibility rather than any single vertical.
