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.
Sha

Reusing an already 301 redirected URL for a very important keyword
I have a question about reusing an already 301 redirected URL Till now I never reused an URLs that has been already redirected with a 301 redirect. However, I just started working on a website where in past they created a lot of 301 redirects without thinking about the future, and now certain URLs, that are currently redirected with a 301, would be very useful (exact match) and needed (for some of the most important keywords for this specific business), to maintain an optimal, homogeneous and "beautiful" URL structure. Has any of you ever reused a URL that was previously redirected with a 301 redirect? If yes what are your experiences with it? Can content on the reused URL (that was previously 301 redirected and than the redirect removed) normally rank if the page is reestablished and the redirect is removed (and you do great content, on page, internal linking, backlinking, .... ) or is such an URL risky / not recommended / "burned" forever and not recommended to be reused again... especially for very important keywords since it present the exact match ?! Thank you very much for all your help! Regards

What do you do with product pages that are no longer used ? Delete/redirect to category/404 etc
We have a store with thousands of active items and thousands of sold items. Each product is unique so only one of each. All products are pinned and pushed online ... and then they sell and we have a product page for a sold item. All products are keyword researched and often can rank well for longtail keywords Would you :- 1. delete the page and let it 404 (we will get thousands) 2. See if the page has a decent PA, incoming links and traffic and if so redirect to a RELEVANT category page ? ~(again there will be thousands) 3. Re use the page for another product - for example a sold ruby ring gets replaces with ta new ruby ring and we use that same page /url for the new item. Gemma

1000 Pages on old website. What to do with the 301 redirects for this domain?
Hi Moz Community, I have a 301 redirect question... I just acquired an old domain: Totally in my niche Domain is 14 years old Website exists of 1000 pages Great amount of backlinks Website is offline since about 2 weeks Will place a new website online asap with new url structure For the 50 best scoring pages I wrote a new, but fully comparable/related article. I will put a 301 redirect from those old to the new pages. My question: What to do with the 950 other url's? Should I put a 301 redirect to the homepage? Should I forward those pages to the 404 page? Should I divide the 950 url's with a 301 redirect to the 50 new ones? Another solution maybe? Any idea what would be the best solution so we can save as much Google juice as possible? Thanks in advance!

Proper 301 redirect code for http to https
I see lots of suggestions on the web for forwarding http to https. I've got several existing sites that want to take advantage of the SSL boost for SEO (however slight) and I don't want to lose SEO placements in the process. I can force all pages to be viewed through the SSL - that's no problem. But for SEO reasons, do I need to do a 301 redirect line of code for every page in the site to the new "https" version? Or is there a way to catch all with one line of code that Google, etc. will recognize & honor?

301 Redirect non existant pages
Hi I have 100's of URL's appearing in Search Console for example: ?p=1_1 These go to on to 5_200 etc.. I have tried to do htaccess and the mod rewrite is on as I can redirect directories to the root i.e RewriteRule ^web_example(.*)$ /$1 [R=301,N,L] However I have tried all kinds of variations to redirect ?p= and either it doesn't work at all or it crashes the website. Can anyone point me in the right direction to fix this.

Questions about the Sandbox and 301 Redirects
Does the sandbox still exist? What if you have a brand new URL and do a 301 redirect from another website because the name of the service business changed? Thanks for any insight and help.

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!

How to create a delayed 301 redirect that still passes juice?
My company is merging one of our sites into another site. At first I was just going to create a 301 redirect from domainA.com to domainB.com but we decided that would be too confusing for customers expecting to see domainA.com so we want to create a page that says something like "We've moved. please visit domainB.com or be redirected after 10 seconds". My question is, how do I create a redirect that has a delay and will this still pass the same amount of juice that a regular 301 redirect would? I've heard that meta refreshes are considered spammy by Google.
