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!

Unsolved Temporary redirect from 302 to 301 for PNG File?
#302HTTP #temporaryredirect
Technical SEO | | Damian_Ed 0
Hi everyone, Recently I have faced a crawl issue with my media images on website. For example this page url https://intreface.com/wp-content/uploads/2022/12/Horion-screen-side-2.png has 302 HTTP Status and the recommendation is to change it 301. I have read the article on temporary redirections here:
https://moz.com/learn/seo/redirection?_ga=2.45324708.1293586627.1702571936-916254120.1702571936
but its not written here how to redirect in my HTML 1 image url not the landing page.

What to do with old content after 301 redirect
I'm going through all our blog and FAQ pages to see which ones are performing well and which ones are competing with one another. Basically doing an SEO content clean up. Is there any SEO benefit to keeping the page published vs trashing it after you apply a 301 redirect to a better performing page?

Max Number of 301 Redirections?
Hi, We currently made a re-design of a website and we changed all our urls to make them shorter. I made more than 300 permanent redirections but plenty more are needed since WMT is showing some more 404s from old urls that I hadn't seen because they were dynamic. The question is, please, is there a limit? I think we have more than 600 already. We don't want to create a php commando to redirect all the old ones to our home, we are redirecting them to their correspondent url. By the way, Im doing them with the 301 method in .htaccess. Thanks in advance.

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

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 ?

Redirect non-www if using canonical url?
I have setup my website to use canonical urls on each page to point to the page i wish Google to refer to. At the moment, my non-www domain name is not redirected to www domain. Is this required if i have setup the canonical urls? This is the tag i have on my index.php page rel="canonical" href="http://www.mydomain.com.au" /> If i browse to http://mydomain.com.au should the link juice pass to http://www.armourbackups.com.au? Will this solve duplicate content problems? Thanks

What tools produce a complete list of all URLs for 301 redirects?
I am project managing the rebuild of a major corporate website and need to set up 301 redirects from the old pages to the new ones. The problem is that the old site sits on multiple CMS platforms so there is no way I can get a list of pages from the old CMS. Is there a good tool out there that will crawl through all the sites and produce a nice spreadsheet with all the URLs on it? Somebody mentioned Xenu but I have never used it. Any recommendations? Thanks -Adrian
