What is a keyword hierarchy and why would I want one?
Keywords are the terms that you believe users will search for, and that you want to rank well on. With My keywords you can track what search rankings you have for each of your keywords, and see how this changes over time. There may be alternative spellings or word orders that you want to track, but that are essentially the same term. You may choose to group these together. Plug in SEO lets you group individual keywords, and groups of keywords, into as many different levels as you like, so that it’s easier to see at a glance how your keywords are performing. You can then drill down into the details of different individual keywords if you want to. For example, a website selling haggis will obviously aim to rank well on the search term “haggis” if possible. There may be lots of common mis-spellings of this (“haggis”, “haggiss”) that in practice, lots of users enter into search engines. Another reason to group keywords is if you have several related keywords that vary by one word. For exam
