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.

Best Practice on 301 Redirect - Images
We have two sites that sell the same products. We have decided to retire one of the sites as we'd like to focus on one property. I know best practice is to redirect apples to apples, which in our case is easily done since the sites sold the same thing. www.SiteABC.com/ProductA can be redirected to www.SiteXYZ.com/ProductA. My question is how far does that thinking go regarding images? Each product has a main product page, of course, and then up to 6 images in some cases. Is it necessary to redirect www.SiteABC.com/ProductA-Image1.jpg to www.SiteXYZ.com/ProductA-Image1.jpg? Or can they all be redirected to just the product page?

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!

Will bad things happen if I cancel 301 site redirect?
Hi, please someone help! We have two identical websites, say A & B. Because of the not so good SEO establishment, site B was built and site A was 301 redirected to site B weeks ago. For some reasons, we have to reuse site A, which means we have to cancel the 301 redirection. (Sound a little crazy) So the question are: 1. Can we conduct the action? 2. If we cant, what's the reason? 3. If we can, what would be the best practice? Thanks for help in advance! Plus: we also CARE what would happen to site B if the 301 is cancelled? Will it grow healthy like a new site?

How many jumps between 301 redirects is acceptable?
For example, I have a page A that should be redirected to page D, but instead A redirects to B, B redirects to C and C redirects to D. It's something I came across and wondering if its worth the dev time to change it. Thanks!

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!
