Code:
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.htm\ HTTP/
RewriteRule ^index\.htm$ http://example.com/ [R=301,L]
RewriteRule ^page\.htm$ http://www.example.com/page-skyblue.html [R=301,L]
why on earth would this page-skyblue now lose it SERP? it had a 1st page SERP for 8 years!

when the only thing that changed was the page-name and extension?
