Redirection in two phases
-
Hi,
One of my client want a website revamp in two phases.
The first phase would be to move the CMS from Sharepoint to Drupal keeping the same content and URLs but the page extension will change (it could become php or just the name of the page without any extension)
The second phase will be a content revamp with URL change.
The first phase will last 3 weeks and then we will push the second phase with the new content and the new URL.
Some shortcuts to make it a more readable:
- old url = OURL
- old url with new extension = OURLEX
- new URL = NURL
My problem is how can I manage the redirections. Should I:
- Phase 1: create one rule that will redirect all the OURL to the OURLEX
- Phase 2: keep the rule I created in phase 1 and add rules for OURLEX to NURL
Or
- Phase 1: create one rule that will redirect all the OURL to the OURLEX
- Phase 2: keep the rule I created in phase 1 and add redirect OURL to NURL
Or
- Phase 1: create one rule that will redirect all the OURL to the OURLEX
- Phase 2: remove the rule I created in phase 1 and add redirect OURL to NURL
Or
- Phase 1: create a rules for each OURL that will redirect all the pages to OURLEX
- Phase 2: remove the rules I created in phase 1 and redirect the OURL to NURL
Or
- Phase 1: create a rules for each OURL that will redirect all the pages to the OURLEX
- Phase 2: keep the rules I created in phase 1 and add rules to redirect the OURLEX to the NURL
Or
- something else you think is better
Difficult to explain, let me know if it's understandable.
Thanks for you help!

Hi Sha,
I'm changing all the file names and we do have a DB behind the site infrastructure (Drupal) but no unique ID so I guess we'll have to do many rules.
Thanks for your help Sha.

Hi GaB,
Sorry, I missed your reference to the URL changes in the original question.
It will depend on exactly what the changes are as to how many Rules will be needed to create the 301 redirects.
If you are retaining file names, but moving whole directories to a new location, then this can be achieved with a single Rule.For example, to 301 Redirect all filenames in Useless Folder 1 to the identical filenames in Relevant Folder 2 can be achieved with a single Rule.
For URLs where the actual filenames will change, or where only some files are relocated you would need to implement individual Rules for each URL.
However, if your site is large, there is another alternative, provided that your URL structure supports it. That would be the use of Database Rewrites to implement the 301 redirects as URL's are requested from the server.
There are some requirements for this to be a viable option:
- There must be a Database behind your site infrastructure
- There must be some identifier in the URLs that will remain constant with the change in site structure. Most commonly this would be a unique product ID number or product name
Basically what happens with Database Rewrites is that when the server receives a request for a URL, the identifier is matched against those in the Database and when the match is found the 301 Redirect is written and the new URL served.
For very large sites Database Rewrites would be the most suitable solution as very long lists of Rules in the .htaccess will eventually impact processing and load times.
Hope that helps,
Sha

Thanks Sha,
You are right, I will do a rewrite for phase 1 but for phase 2 I will need a lot of rewrite rules because the URL structure will change since I optimize it (removing useless folder, adding keywords, etc...) for pretty much every pages.
I don't think I have a choice here.
-
GaB, go with Sha's answer. It is a superior solution to my suggestion. I had a bit of tunnel vision and the rewrite idea did not come to mind.

Hi GaB,
I would suggest a completely different solution.
I would not use 301 Redirects for the Phase 1 change. Rather, I would use a Rewrite Rule to serve the file with the new extension. The Rewrite Rule is basically telling the server to serve OURLEX when a request is made for OURL. The nett result of this is that as far as the Search Engine is concerned, nothing changes.
Here is a Code example which will serve the .php when the .aspx is requested:
RewriteEngine on
RewriteBase /
RewriteRule ^(.*).aspx$ $1.php [L]Then, when Phase 2 is complete, I would implement the 301 redirects using a single Rule once again to permanently redirect all OURL's to NURL's. So, the solution I would recommend is the last one on your list.
Option 6 - Something else I think is better:
- Phase 1: Use Rewrite Rule to satisfy all requests for the OURL by serving the OURLEX
- Phase 2: create one rule that will 301 redirect all the OURL to the NURL
It is best to keep in mind that a 301 redirect should only be used when you intend the redirect to be permanent. Also while Google's stated position is that googlebot will follow multiple 301 redirects, it has also said that "daisy chaining" them is not generally a good practice. There are two reasons for this:
- Google's Matt Cutts has indicated that "at some point we will stop following them if there are a lot of them"
Should you happen to have other domains that are already 301'd to the site, the daisy chain effect is amplified. - As Ryan mentioned, the small amount of link juice that is lost with a 301 Redirect does accumulate over multiple redirects and can have a negative impact.
Hope that helps,
Sha

You are absolutely correct. I failed to mentioned a 3rd step required for that solution:
one rule to redirect all OURLEX to NURL
-
Thanks for your answer.
I'm trying to push a one phase approach but since I'm not sure we will be allowed to do it I prefer to have a back-up plan.
With the methode you mention woudn't it be a problem if the robot index the temporary OURLEX during the 3 weeks (my redirections will all be 301)?
-
Generally speaking, I would not recommend this two phase approach but instead completing the work in a single phase. I'll set that idea aside and presume the two-phased approach is a requirement.
the same content and URLs but the page extension will change (it could become php or just the name of the page without any extension)
I would strongly recommend using the page name without any extension. It not only looks better but it will save you work and benefit your SEO the next time you change systems.
The approach I would recommend is your 3rd option:
- Phase 1: create one rule that will redirect all the OURL to the OURLEX
- Phase 2: remove the rule I created in phase 1 and add redirect OURL to NURL
You want to redirect your site with as few rules as possible to minimize the effort, reduce errors, and minimize server overhead. Additionally, you want to redirect pages with a single redirect. It is a bad practice to allow pages to endure multiple redirects as you will lose a lot of link juice.

CGI Redirects
Trying to 301 old legacy files like oldsite.com/green/red.cgi/blue/ using this htaccess code: Redirect 301 /green/red.cgi/blue/ http://www.newsite.com/summary-page/
Technical SEO | | SoulSurfer8
Instead it's redirecting to: newsite.com/red.cgi/blue/ FYI oldsite.com's htaccess file does not have any global 301 rules that would conflict Does anyone know if cgi files require a different 301 syntax? Thanks!0 -
Redirecting pages from a website to another
Hello Moz community, I’ve got a question and hope you can help! I’ve been working to improve my website’s ranking for the keywords “singing lessons London”. My current website url is http://www.sonic-crew-london.com and the page dedicated to the singing lessons is http://www.sonic-crew-london.com/booking/singinglessons.php I’ve recently bought the url http://www.singing-lessons-london.com which I hope will help to climb Google’s ranks a bit more easily for my chosen keywords. I thought I could redirect the old singing page to the new url. Is that something you would recommend me to do? Is there any specific procedure I should follow to make sure the transition runs smoothly? Any help really appreciated! Many thanks

301 redirecting a mobile site.
Is it possible to selectively 301 redirect mobile/tablet user agents and google robots from the desktop version of a website to a mobile site? Would this preserve the SEO for the desktop website while optimizing the mobile/tablet site for mobile SEO?

How long should you keep 301 redirects?
Hi, Back in 2009 I decided to update an older site from .htm and .shtml to .php. In order to minimize the impact I would go in every month and do a 301 redirect on the .shtml page to the new .php page. So I have many that range from 2009 through 2010. I had left the old 301's because I felt they would only be used if needed but I would think I should clean up my .htaccess by removing the old 301 redirects if they are not needed. How long should you keep this type of 301 redirect? Thanks!

301 Redirect Questions
I have a site I built on a wisiwig editing platform that will not allow a 301 redirect. The site has already been remade and I need to point it to another domain.

Two company websites - should 1 be nofollow?
We are an automotive dealership that is required to keep a manufacturer appointed website. It's pretty terrible so we are having a new site developed in addition to that. We plan on transferring our current domain name to the new site but I am not sure what to do with the older, less useful site. Should I try to have both sites appear in the search results to capture more traffic? Or is that inefficient? Should I make the new site no follow?

Question about Hm Pg Redirects
This question is for MichaelC who was helping me with a previous question that is now closed. Please refer to my question with Subject "Double 301 Redirect" It was about redirecting /home.aspx to simply "/" because that was an old URL and we have some backlinks pointing to it. If the best I could do is redirect "/home.aspx" to something like "#hm", would that work, since everything after the hash symbol is ignored? Thanks Clint
