How to safely reduce the number of 301 redirects / should we be adding so many?
-
Hi All,
We lost a lot of good rankings over the weekend with no obvious cause. Our top keyword went from p3 to p12, for example.
Site speed is pretty bad (slower than 92% of sites!) but it has always been pretty bad. I'm on to the dev team to try and crunch this (beyond image optimisation) but I know that something I can effect is the number of 301 redirects we have in place.
We have hundreds of 301s because we've been, perhaps incorrectly, adding one every time we find a new crawl error in GWT and it isn't because of a broken link on our site or on an external site where we can't track down the webmaster to fix the link. Is this bad practice, and should we just ignore 404s caused by external broken URLs?
If we wanted to reduce these numbers, should we think about removing ones that are only in place due to external broken URLs?
Any other tips for safely reducing the number of 301s?
Thanks, all!

Really helpful. Thanks very much, Sha. Much appreciated!

Hi again Chris,
OK, well that makes it interesting!
First, if the list of 301's in your .htaccess file numbers in the hundreds, then there is definitely cause for concern about the effect it might be having on your load times.
The .htaccess file is read from top to bottom until a rule is matched. The first one that is matched will be used and no rule after that will be checked. Obviously, if there are hundreds of rules to check, this can cause processing bottlenecks.
Now there are some things you might be able to do to alleviate the problem IF you have the right conditions.
-
If your rebuild involved the relocation of an entire directory or directories which still contain the same pages as before, you can write a 301 Redirect for all pages in a directory with a single line of code
-
If there is a database behind your site and you have some means of matching pages from the old URL to the new (for example, is there a unique product ID for each page?) then you can use database lookups to write the redirects on the fly. This will eliminate the processing bottlenecks, but can only work if you have a reliable means of matching the pages.
-
If you have only one competition or offer at a time, then you could use database lookups to match any page with say, "competition" in the URL and 301 it to the current competition page (and the same with "offer").
-
For unknown links from external sites you can use a "catch-all" 301 to catch any other page that returns a 404 and send it to a single page (you put this rule at the very end of your .htaccess so it is the last to be matched). You could send these all to home, a generally relevant landing or category page, or a specially designed 404 page. The most important thing is that the page you redirect them to is as relevant as possible, or provides options that may keep the visitor on your site (search, menus etc). I prefer not to send these "random" 404's to home as they are likely to bring an increase in bounce rate. Since bounce is now acknowledged as a ranking factor, I prefer to keep any traffic with a higher probability of bouncing away from pages with the highest Page Authority (PA).
Hope that helps,
Sha

Yeah, that seems to be the consensus - thanks, Aaron!
Back to the drawing board diagnosing this drop - avg rank over our top 200 keywords has gone from 80-something to 120-something. Not good at all!

Hi Sha,
A combination of things, really. We rebuilt and got rid of a load of legacy pages so there's a few for that reason. We also have a lot of time-limited pages like competitions and special offers that require specific landing pages. The majority are caused by broken links on external sites though - links that never existed, or that have been crawled and added to an autogenerated page incorrectly. The usual nonsense.
So, in brief, there isn't really one cause!
Many thanks for your reply.
Chris

In general, 301 aren't bad unless you have a whole string of them. For instance if a 301 redirected to another 301, then another, etc... If 301's are shallow they usually do not present a problem.
-
Hi BaseKit,
What is the reason for there being so many 404's?
Did you move your site or rebuild your site structure? Do you have a lot of pages that are removed after a short time?
The answer to these questions will help to know what is the best approach for your situation.

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 -
Updating inbound links vs. 301 redirecting the page they link to
Hi everyone, I'm preparing myself for a website redesign and finding conflicting information about inbound links and 301 redirects. If I have a URL (we'll say website.com/website) that is linked to by outside sources, should I get those outside sources to update their links when I change the URL to website.com/webpage? Or is it just as effective from a link juice perspective to simply 301 redirect the old page to the new page? Are there any other implications to this choice that I may want to consider? Thanks!

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
Technical SEO | | Houdoe
www.maindomain.eu
www.maindomain.com
www.otherdomain.nl
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,

301 redirect from Blogger
Hello, I have a client with a Wordpress network of blogs, each blog is owned by a different blogger. Many of them were migrated time ago from Blogger. I have seen that the way used to redirect them is a meta refresh, so no authority is being passed. I cannot find any reliable way of making a 301 from Blogger, There are some plugins, but I'm afraid of using them. Any of you have experience with this situation please? I have even thought about placing a global rel canonical before the meta refresh, but I think that here the problem is the meta refresh itself.... Thank you in advance

301 Redirect How Long until the juice passes through to new site
Hi Guys, Following on from a question i asked last week in regard to a 301 http://www.seomoz.org/q/301-redirect-have-no-ranking I was thinking that i had some kind of issue on the site, although i have gone over it with a fine tooth comb i cannot find any issue's and from the amount of reads the thread has had im sure if there was something obvious it would have been pointed out. So i am quite confident the 301 from site A to site B is fine and working as intended, so my question is how long should it take until the juice is passed From site A to Site B as its 9 weeks now and still down 85% on traffic and even text for my home page if copied into the search bar don't bring up my site Bing is fine and did not see any real traffic drops but Google is not giving me back the rankings i had prior Whenever i have done a 301 before the rankings pretty steady and i see no real loss in rankings but this time ... painful all changes in WMT made

A script to automatically write 301 redirect rules to htaccess?
I was wondering if anyone could help provide some resources on how to automatically write 301 redirect rules to htaccess. Allow me to explain... I'm building a new website and the primary users are businesses. They have their own profile pages on the site. The URL is based off of their Company Name. In the event that they decided to change their name... reasons being, perhaps they mispelled it the first time, or they're removing LLC or adding Inc, I want to also change the URL and redirect the old URL to the new URL. Since the URL is based off of their Company Name, making a change to the company name would make a change to the URL. I know it doesn't have to work this way, but for our purpose this works best. In case the old URL had any links to it, I wanted to see if there was an way to automatically update an htaccess file with a 301 redirect from the old URL to the new one. Could anyone point me in the right direction of how to do this? Perhaps a sample script. I've done a lot of searches on Google and can't seem to find anything. e.g. Original:
Technical SEO | | bimmer540
Name: XYZ Widgets
URL: website.com/xyz-widgets New - business changes their company name in their profile:
Name: XYZ Widgets, Inc.
URL: website.com/xyz-widgets-inc Upon the user saving the changes in their profile, I'd like to write a 301 redirect to an htaccess file:
Redirect 301 /xyz-widgets http://www.website.com/xyz-widgets-inc I know how to manually write redirects and I've got a pretty smart web developer. We've just never triggered a script to automatically write to an htaccess file before. Is this possible? Any resources are appreciated. Any security risks? Thanks!0 -
How long should I keep 301 redirects?
I have modified a the URL structure of a whole section of a website and used mod_rewrite 301 redirect to match the new structure. Now that was around 3 months ago and I was wondering how long should I keep this redirect for? As it is a new website I am quite sure that there are no links around with the old URL structure but still I can see the google bot trying from time to time to access the old URL structure. Shouldn't the google bot learn from this 301 redirect and not go anymore for the old URL?
