Product gallery (or category) pages have been called “the hardest working pages on your site” by UI expert Jared Spool. That’s because they play a critical role in guiding users to the right product page for their needs.
Well designed gallery pages help users choose between products, often through the use of filtering tools to refine the number of choices presented.
This prevents ‘pogo-sticking’ where the user bounces between the gallery page and different product pages, trying to find what they want.
