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

Redirect URLS with 301 twice
Hello, I had asked my client to ask her web developer to move to a more simplified URL structure. There was a folder called "home" after the root which served no purpose. I asked for the URLs to be redirected using 301 to the new URLs which did not have this structure. However, the web developer didn't agree and decided to just rename the "home" folder "p". I don't know why he did this. We argued the case and he then created the URL structure we wanted. Initially he had 301 redirected the old URLS (the one with "Home") to his new version (the one with the "p"). When we asked for the more simplified URL after arguing, he just redirected all the "p" URLS to the PAGE NOT FOUND. However, remember, all the original URLs are now being redirected to the PAGE NOT FOUND as a result. The problems I see are these unless he redirects again: The new simplified URLS have to start from scratch to rank 2)We have duplicated content - two URLs with the same content Customers clicking products in the SERPs will currently find that they are being redirect to the 404 page. I understand that redirection has to occur but my questions are these: Is it ok to redirect twice with 301 - so old URL to the "p" version then to final simplified version. Will link juice be lost doing this twice? If he redirects from the original URLS to the final version missing out the "p" version, what should happen to the "p" version - they are currently indexed. Any help would be appreciated. Thanks

How do I fix a 301 Redirect Loop?
Saturday I waas doing some correcting of some duplicate titles, including nofollowing tags, etc. (my main problem was duplicate titles due to tags and categories being indexed).

Does it really matter to maintain 301 redirect after de-indexing of old URLs?
Today, I was reading latest blog post on SEOmoz blog about. Uncrawled 301s - A Quick Fix for When Relaunches Go Too Well This is very interesting study about 301 & How it useful to maintain traffic. I'm working on eCommerce website and I have done similar stuff on my website. I have big confusion to manage 301 redirect. My website generates new URLs due to following actions. Re-write dynamic URLs. Re-launch entire website on different eCommerce platform. [osCommerce to Magento Commerce] Re-name category. Trasfer one product from one category to another category. I'm managing my 301 redirect with old practice. Excel sheet data from Google webmaster tools and set specific new URLs for redirect. Hoooo... Now, I have 8.5K redirect in htaccess... And, I'm thinking it's too much. Can we remove old 301 redirect from htaccess or not? This is big question for me. Because, all pages are not hyperlink on external website. Google have just de-indexed old URLs and indexed new URLs. So, Is it require to maintain 301 redirect after Google process?

301 Redirect & Cloaking
HEllo~~~~ People. I have a question regarding on cloaking. I will be really greatful if you can help me with question. I have a site www.example.com and it is targeting for multi countries. So I use sub directories for targeting multi countries. e.g. www.example.com/us/ www.example.com/de/ www.example.com/hk/ ....... so on and on. Therefore, when people type www.example.com, I use IP delivery to send users to each coutries. Here is my question. I use 301 redirect for IP delivery, which means when user enter www.example.com, my site read user's IP and send them to right country site by 301 redirect. In this case, is there any possibility that Google considers it as cloaking? Please people.... share me some ideas and thoughs.

How best to redirect URL from expired classified ads?
We have problem because our content are classifieds. Every ad expired after one or two mounts and then ad becomes inactive and we keep his page for one mount latter like a same page but we ad a notice that ad is inactive. After that we delete the ad and his page but need to redirect that URL to search results page which contains similar ads because we don't want to lose the traffic form that pages. How is the best way to redirect ad URL? Our thinking was to redirect internal without 301 redirection because the httacces file will be very big after a while and we are thinking to try a canonicalization because we don't want engine to think that we have to much duplicate content.
