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.

Is 301 redirect the only way when using Vanity URLs?
We have been using vanity urls for some of our pages. Mostly the pages that have a vanity URL have a long URL length. But now the problem is, the vanity URL is getting displayed on the search engine when the particular keyword related to the page is entered. I checked the google search console, the vanity URL is indexed and the original URL remains unindexed. What should I do? Is adding 301 redirect to the vanity URLs are solution? Since some of vanity URLs are not redirecting to the original. Some of the original pages are not getting traffic. Also, can using canonical tag help?

301 redirect not working
Hi there! I have recently moved a domain that has been indexed by google and setup redirects so that it forwards to the new domain. It seems like the only redirect that actually is working is the canonical and main domain but every other page and or page nested within a folder are not working. Here is an example of some of the redirects. Am I doing this wrong? It seems to be going to the new domain but can't find the actual pages.... RewriteEngine On

subfolder C has files g, h & i A, B & C folders need to be X, Y & Z Will the following work? RewriteRule ^subfolder-A/* http://www.domain.com/subfolder-X/ [R=301,L]
RewriteRule ^subfolder-B/* http://www.domain.com/subfolder-Y/ [R=301,L]
RewriteRule ^subfolder-C/* http://www.domain.com/subfolder-Z/ [R=301,L] will this result in visitors to http://www.domain.com/subfolder-B/f.html being redirected to http://www.domain.com/subfolder-Y/f.html? All on the same domain. in reality we are talking hundreds of sub folders and thousands of files so we don't want to have to reference every file individually in the htaccess. Thanks0 -
301 redirects & merging two sites into one
We have a client that has two sites that rank well for different searches in their market. The main pages ranking are things like advice articles and news pieces. For various reasons, they just want one site. I believe they need to duplicate the content from the outgoing site and place it on the main site, with a 301 redirect from each old page to each new one. What happens when they eventually want to redirect the entire domain? Would these smaller, internal redirects become obsolete, therefore removing any link value they once had? I am not sure how this works or if there is a best practice way to do this. Thanks Gareth

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?

Trailing Slashes In Url use Canonical Url or 301 Redirect?
I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?

How do I redirect index.html to the root / ?
The site I've inherited had operated on index.html at one point, and now uses index.php for the home page, which goes to the / page. The index.html was lost in migrating server hosts. How do I redirect the index.html to the / page? I've tried different options that keep giving ending up with the same 404 error. I tried a redirect from index.html to index.php which ended in an infinite loop. Because the index.html no longer exists in the root, should I created it and then add a redirect to it? Can I avoid this by editing the .htaccess? Any help is appreciated, thanks in advance!

Why is a 301 redirected url still getting indexed?
We recently fixed a redirect issue in a website, and although it appears that the redirection is working fine, the url in question keeps on getting crawled, indexed and cached by google. The redirect was done a month ago, and google shows cached version of it, even for a couple of days ago. Manual checking shows that its being redirected, and also a couple of online tools i checked report a 301 redirect. Do you have any idea why this could be happening? The website I'm talking about is www.hotelmajestic.gr and its being redirected to www.hotel-majestic.gr
