I have a client who is considering getting rid of a /shows landing page and redirecting it to /shows/headliners bc they think the /shows page is useless (I agree).
The headliners page has the outbound links as the /shows page, meaning users & crawlers can still navigate to all the sub-pages of /shows (there is a handy side-bar nav on the left hand side). Any links pointing to /shows will redirec to /shows/headliners.
The client wants to know of any potential detriment to seo performance because the /shows page was part of the URL structure. It would be like removing /services landing page and redirecting traffic to the top service page (/service/service1), if the top service page has navigable links to all the other services and isn`t lacking in content.
