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

File Name Similarity

Image uniqueness is an opaque thing to measure, but it seems that Google is starting to take this more seriously.It seems that merchants whose images are very unique, highly detailed, and distinguishable are much more reliably indexed. For example, something like a white T-shirt on a light colored background with very little detail on the T-shirt seems to be demoted by Google.This concept is particularly important for merchants who are selling products that are not unique—like a retailer who carries many brand names.&nbsp;

Image Uniqueness & Duplicate Content

I launched <a href="https://apps.shopify.com/image-sitemap?ref=william-belk">Image Sitemap for Shopify </a>in December 2017. To date we have submitted over 500k images to Google Search on behalf of our customers—with those customers seeing an average of 648% increase in indexed images . I started with a hypothesis about helping merchants reliably improve their Google image indexing. This hypothesis came about due to some limitations with the Shopify platform along with the massive amount of effort needed to manage large image sitemaps (or those greater than 2,000 images and 30,000 lines of XML — some of our customers’ image sitemaps contain more than 500k lines of XML). It seems that my hypothesis is on the way to being strongly validated.

By default, Shopify only includes a single image per product in their standard image sitemap. The <a href="https://apps.shopify.com/image-sitemap?ref=william-belk">Image Sitemap for Shopify </a>app submits every single image to Google and includes important product metadata as well. We also resubmit all data to Google on every catalog change. Google seems to like what we’re doing, so I wanted to share our findings so far.

Apart from the obvious task of submitting every product image to Google, regardless of catalog size—there seem to be some interesting findings when looking at the following measures:

File name similarity seems to be a substantial predictor of image indexing in Google.

Our customers whose average correlation is above 0.40 are indexing 40% more images in Google than those whose correlation is below 0.40.
