Related anchor words link to a page using a variation of the target keyword. They are like partial match keywords, but related anchors don’t include the precise keyword phrase. 

You will want to build some related anchors to help Google’s crawlers better understand what your links are all about. Plus, they keep your link profile diverse so Google is less likely to hit you for spammy links.

Related Anchor Examples:

• Yemen’s water crisis if you are linking to a page targeting “Yemen cholera epidemic”
• Adidas Yeezy Boost targeting “buy running shoes”
• Social media marketing targeting “Facebook content strategy”
