301 redirect: canonical or non canonical?
-
Hi,
Newbie alert!
I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly.
The current site uses canonical header tags. The new site will also use canonical tags.
Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new?
Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case?
Thx in anticipation.

The most accurate way is to do it manually. Doing a site:YOURDOMAIN.com in Google will alert you to most of the ugly URLs you want to get rid of.

Thanks for that David . . . makes sense.
Can you recommend any tools to help with this job or is it still mostly a manual process?
Cheers.

"Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new?"
Any URL's that are indexed should be redirected to the correct version. For example if you have both a database URL and a canonical URL both indexed in search results, then they both should be sent to the correct version.
Also, having only canonical URLs in your submitted sitemaps will help to remove a lot of these, even without redirects.

Ok, here is my understanding regarding canonicals and how it works with redirect. 301 redirect means the old URL is shifting its all value and user to the new domain (unlike 302 that only derives traffic but contain the URL value to itself only).
Whereas Canonicals indicates Google the preferred version of the domain so theoretically if you use the canonicals on every page Google should pick the redirected page as 301 will take Google to the final destination anyways…
What will I do?
If Possible, I will map all the redirected URLs and remove canonicals from there just to be on the safe side but I don’t think having there will be much of a difference as Google as at least that smart.
Hope this helps!

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 Redirects in subfolders
Hi, we're making our site into a static site but I would like to transfer the Google juice. Most of the links and database exist on subfolders though. Could I simply do 301 redirects on the subfolders and retain the value or does it have to be on the full domain?

Increase 404 errors or 301 redirects?
Hi all, I'm working on an e-commerce site that sells products that may only be available for a certain period of time. Eg. A product may only be selling for 1 year and then be permanently out of stock. When a product goes out of stock, the page is removed from the site regardless of any links it may have gotten over time. I am trying to figure out the best way to handle these permanently out of stock pages. At the moment, the site is set up to return a 404 page for each of these products. There are currently 600 (and increasing) instances of this appearing on Google Webmasters. I have read that too many 404 errors may have a negative impact on your site, and so thought I might 301 redirect these URLs to a more appropriate page. However I've also read that too many 301 redirects may have a negative impact on your site. I foresee this to be an issue several years down the road when the site has thousands of expired products which will result in thousands of 404 errors or 301 redirects depending on which route I take. Which would be the better route? Is there a better solution?

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

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). Now this morning I see that one of my pages refuses to load, citing a 301 redirect loop. http://www.incredibleinfant.com/feeding/switching-baby-formula/ Originally, the page was posted under the wrong category. http://www.incredibleinfant.com/uncategorized/switching-baby-formula I resaved it under the correct category (feeding) and now it won't load. Can someone help me figure out how to correct this mess? Thanks so much Heather

A script to automatically write 301 redirect rules to htaccess?
I was wondering if anyone could help provide some resources on how to automatically write 301 redirect rules to htaccess. Allow me to explain... I'm building a new website and the primary users are businesses. They have their own profile pages on the site. The URL is based off of their Company Name. In the event that they decided to change their name... reasons being, perhaps they mispelled it the first time, or they're removing LLC or adding Inc, I want to also change the URL and redirect the old URL to the new URL. Since the URL is based off of their Company Name, making a change to the company name would make a change to the URL. I know it doesn't have to work this way, but for our purpose this works best. In case the old URL had any links to it, I wanted to see if there was an way to automatically update an htaccess file with a 301 redirect from the old URL to the new one. Could anyone point me in the right direction of how to do this? Perhaps a sample script. I've done a lot of searches on Google and can't seem to find anything. e.g. Original:
Technical SEO | | bimmer540
Name: XYZ Widgets
URL: website.com/xyz-widgets New - business changes their company name in their profile:
Name: XYZ Widgets, Inc.
URL: website.com/xyz-widgets-inc Upon the user saving the changes in their profile, I'd like to write a 301 redirect to an htaccess file:
Redirect 301 /xyz-widgets http://www.website.com/xyz-widgets-inc I know how to manually write redirects and I've got a pretty smart web developer. We've just never triggered a script to automatically write to an htaccess file before. Is this possible? Any resources are appreciated. Any security risks? Thanks!0 -
301 redirects & merging two sites into one
We have a client that has two sites that rank well for different searches in their market. The main pages ranking are things like advice articles and news pieces. For various reasons, they just want one site. I believe they need to duplicate the content from the outgoing site and place it on the main site, with a 301 redirect from each old page to each new one. What happens when they eventually want to redirect the entire domain? Would these smaller, internal redirects become obsolete, therefore removing any link value they once had? I am not sure how this works or if there is a best practice way to do this. Thanks Gareth
