I'm uploading a new site very soon and don't want the error page and contact form confirmation pages to be indexed by search engines, but I wondered whether anyone knows whether there is any reason or benefit in changing the meta information from noindex:nofollow to noindex:follow ?
Am I right in thinking that search engines follow links from your index page through all folders until they reach a dead-end or have indexed the page that links from a near dead-end page?
The example on my new site is that apart from all other pages within the site which use includes for all links, the error and contact form confirmation pages only have a link back to the index page, privacy policy and terms of use pages.
So, is there any reason or benefit in changing the meta information to noindex:follow?
Error pages and contact confirmation pages? I wouldn't have those set to follow, I see no reason why it would benefit you. Are you using custom error pages?
I never think local myself (my businesses does not run that way). However does your client seek local advertising? If so I would put the local address on the contact page and promote it for the SEs, not hide it.
If no local results are a concern I would do a no index, file, and cache. I would then follow it up with a deny in your robots.txt.
