How long should you keep 301 redirects?
-
Hi,
Back in 2009 I decided to update an older site from .htm and .shtml to .php. In order to minimize the impact I would go in every month and do a 301 redirect on the .shtml page to the new .php page. So I have many that range from 2009 through 2010.
I had left the old 301's because I felt they would only be used if needed but I would think I should clean up my .htaccess by removing the old 301 redirects if they are not needed.
How long should you keep this type of 301 redirect?
Thanks!

Hi,
Should the 301 redirects appear in the sitemap.xml as this could get pretty big over the years?

Here's another idea. Rather than worrying about numerous 301 redirects, why not just set up a rewrite rule in .htaccess using mod_rewrite (if you're using an Apache server) that rewrites all URL's with a file extension (.htm, .html, .shtml etc) to just end with a trailing slash or not include the extension?
One rewrite rule would then redirect all URL's that have an extension to a version without, and subsequently, this would be the only version that would end up getting indexed in search engines and that anyone would ever see. Plus it keeps your URL structure much cleaner.

This should explain everything for you need to know for a variety of options: http://www.webconfs.com/how-to-redirect-a-webpage.php
Personally I never remove 301's (being a "permanent" redirect), for fear of 404's from some outside links.
Here's a thread from Matt Cutts discussing the difference between 301 and 302 redirects: http://www.mattcutts.com/blog/seo-advice-discussing-302-redirects/

What's the best way to implement a 301 redirect if you don't have htaccess?
-
Are people still linking to you at your old .htm pages? Then you should keep the 301s in place. There's no need to "clean up" your .htaccess.
If you decide to remove the 301s anyway and start seeing a lot of 404s in Webmaster Tools, that's a good indication you should put the 301s back in place.

I have a question about the impact of a root domain redirect on site-wide redirects and slugs.
I have a question about the impact (if any) of site-wide redirects for DNS/hosting change purposes. I am preparing to redirect the domain for a site I manage from https://siteImanage.com to https://www.siteImanage.com. Traffic to the site currently redirects in reverse, from https://www.siteImanage.com to https://siteImanage.com. Based on my research, I understand that making this change should not affect the site’s excellent SEO as long as my canonical tags are updated and a 301 redirect is in place. But I wanted to make sure there wasn’t a potential consequence of this switch I’m not considering. Because this redirect lives at the root of all the site’s slugs and existing redirects, will it technically produce a redirect chain or a redirect loop? If it does, is that problematic? Thanks for your input!

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 for a Very Long URL
Hey gang, Thanks ahead of time for the help. I have a url somehow that is very very long: http://www.colbysphotography.com/wedding-caterers-knoxville-east-tennessee/Here is an extensive list of wedding venues in the Knoxville and East Tennessee region. If you find that any of these links are not working, that the venues are no longer in business, or have a suggestion for an additional venue (at no charge), please contact Colby. Colby's Photography works hard on keeping this list helpful. I have tried Yoast Premium on a wordpress site to redirect the url but it doesn't seem to keep. I've tried a few other redirect plugins with not help either. I would love some suggestions on this one! Colby

Updating inbound links vs. 301 redirecting the page they link to
Hi everyone, I'm preparing myself for a website redesign and finding conflicting information about inbound links and 301 redirects. If I have a URL (we'll say website.com/website) that is linked to by outside sources, should I get those outside sources to update their links when I change the URL to website.com/webpage? Or is it just as effective from a link juice perspective to simply 301 redirect the old page to the new page? Are there any other implications to this choice that I may want to consider? Thanks!

To 301 redirect or not...
Hi guys i'd like to get your opinion on this. We currently have two sites, site A is the old one with PA44 and DA33. Site B is the new one which is going to replace site A it currently has PA37 and DA24 Our plan for the future is to shut down site A and redirect all pages using 301 to the relevant pages on side B. Currently we have some links in place for a couple of keywords on site A to site B which seems to be working great for our ranking. Now i'm wondering if this is maybe a good option, to give back links from A to B or will i pass through more link juice when redirecting everything? (ps. both are e commerce sites hosted and registred with different companies)
