Hi There,Got a few question regarding SEO for Photogalleries. - What are the best practices in terms of SEO whenever we have a gallery of pictures and each picture has a different URL? Currently, we are using a unique metadescription that is on the first page of the gallery, then for the remaining ones, we are using the captions of the pictures as metadescriptions.Is the the good way to go? Is it better to have short metadescriptions (being the captions of our pictures) or duplicate metadescriptions (the same one across the pictures)?- is there any other recommendations used by other websites?Thanks!
