Selective 301 redirections of pages within folders
-
Redirection Puzzle - it's got me puzzled anyhow!
The finished website has just been converted from an old aspx affair to a wordpress site. Some directory structures have changed significantly; there appears to be a load of older medical articles that have not been added back in and it sounds unlikely that they will be. Therefore unmatched old news articles need to be pointed to the top news page to keep hold of any link value they may have accrued.
The htaccess file starts with ithemes security's code, Followed by the main wordpress block and I have added the user redirects to the final section of the htaccess file . I have been through the redirects and rewrites line by line to verify them and the following sections are giving me problems. This is probably just my aging brain failing to grasp basic logic.
If I can tap into anybody's wisdom for a bit of help I would appreciate it. My eyes and brain are gone to jelly.
I have used htaccesscheck.com to check out the underlying syntax and ironed out the basic errors that I had previously missed. The bulk of the redirects are working correctly.
#Here there are some very long media URLs which are absent on the new site and I am simply redirecting visiting spiders to the page that will hold media in future. Media items refuse to redirect
Line 408 redirect 301 /Professionals/Biomedicalforum/Recordedfora/Rich%20Media%20http:/kplayer.kcl.ac.uk/ess/echo/presentation/15885525-ff02-4ab2-b0b9-9ba9d97ca266 http://www.SITENAME.ac.uk/biomedical-forum/recorded-fora/Line 409 redirect 301 /Professionals/Biomedicalforum/Recordedfora/Quicktime%20http:/kplayer.kcl.ac.uk/ess/echo/presentation/15885525-ff02-4ab2-b0b9-9ba9d97ca266/media.m4v http://www.SITENAME.ac.uk/biomedical-forum/recorded-fora/
Line 410 redirect 301 /Professionals/Biomedicalforum/Recordedfora/Mp3%20http:/kplayer.kcl.ac.uk/ess/echo/presentation/15885525-ff02-4ab2-b0b9-9ba9d97ca266/media.mp3 http://www.SITENAME.ac.uk/biomedical-forum/recorded-fora/
#Old site pagination URLs redirected to new "news" top level page - Here I am simply pointing all the pagination URLs for the news section, that were indexed, to the main news page. These work but append the pagination code on to the new visible URL. Have I got the syntax correct in this version of the lines to suppress the appended garbage?
RewriteRule ^/LatestNews.aspx(?:.*) http://www.SITENAME.ac.uk/news-events/latest-news/? [R=301,L]
#On the old site many news directories (blog effectively) contained articles that are unmatched on the new site, have been redirected to new top level news (blog) page: In this section I became confused about whether to use Redirect Match or RewriteRule to point the articles in each year directory back to the top level news page. When I have added a redirectmatch command - it has been disabling the whole site! Despite my syntax check telling me it is syntactically correct. Currently I'm getting a 404 for any of the old URLs in these year by year directories, instead of a successful redirect. I suspect Regex lingo is not clicking for me
My logic here was rewrite any aspx file in the directory to the latest news page at the top. This is my latest attempt to rectify the fault. Am I nearer with my syntax or my logic? The actual URLs and paths have been substituted, but the structure is the same).So what I believe I have set up is: in an earlier section; News posts that have been recreated in the new site are redirected 1 - 1 and they are working successfully. If a matching URL is not found, when the parsing of the file reaches the line for the 1934 directory it should read any remaining .aspx URL request and rewrite it to the latest news page as a 301 and stop processing this block of commands. The subsequent commands in this block repeat the process for the other year groups of posts. Clearly I am failing to comprehend something and illumination would be gratefully received.
RewriteRule ^/Blab/Blabbitall/1934/(.*).aspx http://www.SITENAME.ac.uk/news-events/latest-news/ [R=301,L]
#------Old site 1933 unmatched articles redirected to new news top level page
RewriteRule ^/Blab/Blabbitall/1933/(.*).aspx http://www.SITENAME.ac.uk/news-events/latest-news/ [R=301,L]
#------Old site 1932 unmatched articles redirected to new news top level page
RewriteRule ^/Blab/Blabbitall/1932/(.*)/.aspx http://www.SITENAME.ac.uk/news-events/latest-news/ [R=301,L]
#------Old site 1931 unmatched articles redirected to new news top level page
RewriteRule ^/Blab/Blabbitall/1931/(.*)/.aspx http://www.SITENAME.ac.uk/news-events/latest-news/ [R=301,L]
#------Old site 1930 unmatched articles redirected to new news top level page
RewriteRule ^/Blab/Blabbitall/1930/(.*)/.aspx http://www.SITENAME.ac.uk/news-events/latest-news/ [R=301,L]
Many thanks if anyone can help me understand the logic at work here.

Thanks Everett - Just popping across to Stack Overflow now!

Hello Tom,
I think using RewriteRule is the way to go so no problem there. You may need to use a RewriteCond (condition) to exclude certain directories so you're not redirecting the entire site. You can read more here: http://stackoverflow.com/questions/4307780/whats-the-difference-between-rewriterule-and-redirect-301 .
I'll keep an eye on this and hopefully someone with more direct implementation experience with regex an help out.

301 redirected all my pages to my new domain, now I have a problem with Google Search Console
Hi guys! I bought a new domain name and redirected all my URLs from the old domain to the new one. Everything worked perfectly but now I have a little problem. I want to use the option 'Address Change' in google search console. Step 1 Works (Select new website in the list) Step 2 Works (Confirm that the 301 are working) Step 3 Asks me to Verify the old domain (huh!?) in order to complete the request. Obviously that doesn't work because my 301s WORKS! So if I try to verify the old website by putting a google file in the root of my domain Google tries to access it and it automatically redirects to the new domain. I must be missing something lol help!

301 redirect adding trailing slash to url
I am looking into a .htacess file for a site I look after and have noticed that the urls are all 301 redirecting from a none slash directory to a trailing slashed directory/folders. e.g. www.domain.com/folder gets 301 redirected to www.domain.com/folder/ Will this do much harm and reduce the effect on the page and any links pointing to the site be lessened? Secondly I am not sure what part of my htaccess is causing the redirect. RewriteCond %{HTTP_HOST} !^www.domain.co.uk [NC] RewriteCond %{HTTP_HOST} !^$

RewriteRule ^(.*) http://www.domain.co.uk/$1 [L,R,NE] RewriteCond %{THE_REQUEST} ^./index.php
RewriteRule ^(.)index.php$ /$1 [R=301,L] or could a wordpress ifmodule be causing the problem? Any info would be apreciated.0 -
Page disappeared from Google index. Google cache shows page is being redirected.
My URL is: http://shop.nordstrom.com/c/converse Hi. The week before last, my top Converse page went missing from the Google index. When I "fetch as Googlebot" I am able to get the page and "submit" it to the index. I have done this several times and still cannot get the page to show up. When I look at the Google cache of the page, it comes up with a different page. http://webcache.googleusercontent.com/search?q=cache:http://shop.nordstrom.com/c/converse shows: http://shop.nordstrom.com/c/pop-in-olivia-kim Back story: As far as I know we have never redirected the Converse page to the Pop-In page. However the reverse may be true. We ran a Converse based Pop-In campaign but that used the Converse page and not the regular Pop-In page. Though the page comes back with a 200 status, it looks like Google thinks the page is being redirected. We were ranking #4 for "converse" - monthly searches = 550,000. My SEO traffic for the page has tanked since it has gone missing. Any help would be much appreciated. Stephan

CNAME vs 301 redirect
Hi all, Recently I created a website for a new client and my next job is trying to get them higher in Google. I added them in OSE and noticed some strange backlinks. To my surprise the client has about 20 domain names. All automatically poiting to (showing) the same new mainsite now. www.maindomain.nl www.maindomain.be

www.otherdomain.com
... Some of these domains have backlinks too (but not so much). I suggested to 301 redirect them all to the main site. Just to avoid duplicate content. But now the webhoster comes into play: "It's a problem, client has only 1 hosting account, blablabla...". They told me they could CNAME the 20 domains to the main domain. Or A-record them to an IP address. This is too technical stuff for me. So my concrete questions are: Is it smart to do anything at all or am I just harming my client? The main site is ranking pretty well now. And some backlinks are from their copy sites (probably because everywhere the logo links to the full mainsite url). Does the CNAME or A-record solution has the same effect as a 301 redirect, from SEO perspective? Many thanks,

I've consolidated other domains to a single one with 301 redirects, yet the new domain authority in MOZ is much less that the redirected ones. Is that right?
I'm trying to increase the domain authority of my main site, so decided to consolidate other sites. One of the other sites has a much higher domain authority, but I don't know why after a 301 redirect, the new site's domain authority hasn't changed on over a month. Does MOZ take account of thes types of things?

If a permanent redirect is supposed to transfer SEO from the old page to the new page, why has my domain authority been impacted?
For example, we redirected our old domain to a new one (leaving no duplicate content on the old domain) and saw a 40% decrease in domain authority. Isn't a permanent redirect supposed to transfer link authority to the place it is redirecting to? Did I do something wrong?

Can I remove 301 redirects after some time?
Hello, We have an very large number of 301 redirects on our site and would like to find a way to remove some of them. Is there a time frame after which Google does not need a 301 any more? For example if A is 301 redirected to B, does Google know after a while not to serve A any more, and replaces any requests for A with B? How about any links that go to A? Or: Is the only option to have all links that pointed to A point to B and then the 301 can be removed after some time? Thank you for you you help!

301 redirects twice
We currently have some 301 redirects set up on our site however sometimes a page will redirect twice before reaching the final location. Is this OK from an SEO perspective to have a page redirect twice or should we concentrate on reducing it to one?
