Search engines don’t like duplicate content—whether text or images. Good Gallery uses innovative technology to prevent search engines from penalizing you if you use the same image more than once in a gallery.
Automatic Canonical References
Canonical link elements help prevent duplicate content issues by providing search engines with a link to preferred information. This helps search engines immediately understand which piece of content is most important on your website.
When you use the same image in more than one gallery on your website, our systems automatically create a canonical reference that points to the image in your most prominent gallery. This feature helps prevent duplicate content issues on your website.
