When closing an Acoustic Campaign landing page, the "Close page" settings allow entry of a URL that the user should be redirected to if they try to load the closed page in their browser.

On the backend, when a redirect URL is specified, Acoustic unfortunately implements the redirect with a 302 (temporary redirect).

Read any current article on reasons for implementing a redirect as a 301 vs 302 and see that 301 redirects are preferred, given how search engines, esp. Google, process redirects. The new redirect page could be badly ranked, or worse, considered a dup of the original (now closed) page, and removed from search results.

Therefore, please update the Close page settings to allow selection of:
( ) Permanent redirect (301)
( ) Temporary redirect (302)
