File Name Similarity

File name similarity seems to be a substantial predictor of image indexing in Google. Google likes to see image file names that are very similar to both the product title and the product handle (or url pathname) . A correlation above 0.40 seems to be ideal. We calculate this correlation using Dice’s Coefficient.

For example:
File name: foo-bar-pocket-tshirt-striped-red-front.jpg
Product title: Foo Bar Pocket T-Shirt — Striped
Product handle: /products/foo-bar-pocket-tshirt-striped-red
