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

301 redirects delay in picking up
Hi I have been involved in the redesign/development of a website which has up until now had a lot of international traffic. On day of migration I uploaded all the 301 redirects to the website (wordpress) using Simple 301 redirect plugin. I tested a number of them and they appeared to be working. I also submitted the new sitemaps to Search Console. Since migration international traffic - particularly from countries such as india, Phillipines, Sri Lanka etc have significantly dropped off whereas the local traffic and some of the international traffic such as USA has remained fairly consistent. Looking at Analytics and entrances recently it appears as though search results are/were showing a number of pages with 404's (one in particular which received significant traffic and for which I had created a 301 redirection) - I have checked this page using the old url and it re-directs correctly for me and today asked a colleague in India to also check - he is getting the redirection fine. Does Google.in take a significantly longer time to pick these up in search results? Or am I missing something?

301 Redirects Relating to Your XML Sitemap
Lets say you've got a website and it had quite a few pages that for lack of a better term were like an infomercial, 6-8 pages of slightly different topics all essentially saying the same thing. You could all but call it spam. www.site.com/page-1 www.site.com/page-2 www.site.com/page-3 www.site.com/page-4 www.site.com/page-5 www.site.com/page-6 Now you decided to consolidate all of that information into one well written page, and while the previous pages may have been a bit spammy they did indeed have SOME juice to pass through. Your new page is: www.site.com/not-spammy-page You then 301 redirect the previous 'spammy' pages to the new page. Now the question, do I immediately re-submit an updated xml sitemap to Google, which would NOT contain all of the old URL's, thus making me assume Google would miss the 301 redirect/seo juice. Or do I wait a week or two, allow Google to re-crawl the site and see the existing 301's and once they've taken notice of the changes submit an updated sitemap? Probably a stupid question I understand, but I want to ensure I'm following the best practices given the situation, thanks guys and girls!

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

Can you 301 redirect a page to an already existing/old page ?
If you delete a page (say a sub department/category page on an ecommerce store) should you 301 redirect its url to the nearest equivalent page still on the site or just delete and forget about it ? Generally should you try and 301 redirect any old pages your deleting if you can find suitable page with similar content to redirect to. Wont G consider it weird if you say a page has moved permenantly to such and such an address if that page/address existed before ? I presume its fine since say in the scenario of consolidating departments on your store you want to redirect the department page your going to delete to the existing pages/department you are consolidating old departments products into ?

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?

200 Redirects for SEO instead of 301
We are working with a company on re-platforming our website. On a call yesterday they outlined a strategy to use 200 redirects for our top keywords instead of 301s. I am not familiar with this type of redirect and was wondering if anyone could provide some more insight.

301 Redirect vs Domain Alias
We have hundreds of domains which are either alternate spelling of our primary domain or close keyword names we didn't want our competitor to get before us. The primary domain is running on a dedicated Windows server running IIS6 and set to a static IP. Since it is a static IP and not using host headers any domain pointed to the static IP will immediately show the contents of the site, however the domain will be whatever was typed. Which could be the primary domain or an alias. Two concerns. First, is it possible that Google would penalize us for the alias domains or dilute our primary domain "juice"? Second, we need to properly track traffic from the alias domains. We could make unique content for those performing well and sell or let expire those that are sending no traffic. It's not my goal to use the alias domains to artificially pump up our primary domain. We have them for spelling errors and direct traffic. What is the best practice for handling one or both of these issues?
