I have a news site about global sport industry. There are news, and some of the news have galleries, such as:
News URL:
example.com/news/tiger-woods-win-the-cup
Gallery URLs:
example.com/news/tiger-woods-win-the-cup/1
example.com/news/tiger-woods-win-the-cup/2
example.com/news/tiger-woods-win-the-cup/3
Should I add canonical tag into the gallery HTML as like below?
<link rel="canonical"
href="http://www.example.com/news/tiger-woods-win-the-cup" />
Note: gallery pages have no written content except of the same news headline; it's all photographs (1.jpg, 2.jpg etc.).
Are all photographs also included on /news/tiger-woods-win-the-cup?
If no:
You must not use the canonical link type, because you news page doesn’t "identify content that is either duplicative or a superset of the content at the context (referring) IRI" (which would be your gallery pages).
If yes:
You may use the canonical link type.
