You'd think that when you do a domain + keyword search, Google returns the most relevant URL on that domain for that keyword.
However, when searching for just the keyword, the result in the SERPs shows a different URL on the domain.
for example, if you search for:
domain.com red widgets
You get the top pages for red widgets on domain.com
Let's say the first page is
however, if you search for jsut red widgets, the SERP might show domain.com/red-widgets-plastic.htm
Is this odd, or normal?
