Question, is it ok for one of the pages levels to 404? (SEO-wise)
Let's say I have a sitemap like this:
example.com --/services --/foo --/bar --/sectors --/my-sector --/another-sector --/the-sector --/stuff --/about-example --/contact --/etc --/etc
This makes a lot of structural sense. However, from a design point of view, I think having a page to show all the sectors (example.com/sectors) is pointless since all of the sector pages can be accessed from the home page, main navigation, and in each sector page.
Would there be any SEO consequences if the /sectors page were to 404?
Note: in the sitemap 'example.com/sectors' would not be included.
