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.

Max Number of 301 Redirections?
Hi, We currently made a re-design of a website and we changed all our urls to make them shorter. I made more than 300 permanent redirections but plenty more are needed since WMT is showing some more 404s from old urls that I hadn't seen because they were dynamic. The question is, please, is there a limit? I think we have more than 600 already. We don't want to create a php commando to redirect all the old ones to our home, we are redirecting them to their correspondent url. By the way, Im doing them with the 301 method in .htaccess. Thanks in advance.

How to redirect 302 status to 301 status code using wordpress
I just ran the link opportunity option within site explorer and it shows that 31 pages are currently in a 302 status. Should I try to convert the 302's to 301's? And what is the easiest way to do this? I see several wordpress plugins that claim to do 301 redirects but I don't know which to choose. Any help would be greatly appreciated!

Changing title tags, do we need 301 redirects
I found many duplicate title tags and I'm in the process of changing it Do I need 301 redirects in place when I switch it? I am only changing the title tag. Also, we are switching over to a new site very soon, I am worried that we might be using too many 301 redirect "hops" because we are doing a lot of optimization as well. (video from matt cutts describing 301 redirects and hops: http://www.youtube.com/watch?v=r1lVPrYoBkA. Does anyone have any experience in doing too many redirect hops that it affected your rankings? Any good ideas to avoid this?

Switching from a .org to .io (301 domain redirect)
I'm considering switching my main site from a .org to .io address; the .org is an exact match domain which helped to kickstart it a few years ago and now has about 50% repeat visitors, but was thrown off the Apple affiliation program for trademark infringement. I've found and purchased a nice (non-infringing) .io domain, and I've read the advice here on how to properly 301 the old domain; but my question is - does it matter that it's .io? Is this going to significantly hurt my rankings, even when everything has been 301'd properly? Another thought I had is that I may actually come out better off in the long run, what with Google penalties being applied to exact match domains. Is this a ranking suicide? If so, I'm tempted to leave it as is; even without the affiliation, it's making a good amount every month in ad fees that I don't want to disrupt. Thanks all!

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:

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
