I used to use the Google provided search box to display search results on my site. I recently stopped using it in part because analytics and GWT reported thousands of search urls, which later become 404 errors, despite my noindex meta tag.
- I removed the search box
- I removed the search results page
- I redirected the search results page to Google
RedirectMatch permanent ^/search-results-page$ http://www.google.com
That last part is creating some ODD behavior, on Google's end. Visiting any of the old search result urls on MY site now results in Google displaying my results on THEIR site, complete with my color layout. Technically this is Google showing content on their own site so part of me thinks I shouldn't worry but... what would you do?
