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

How effective are 301 redirects in passing page rank?
I have a blog which is ranking well for certain terms, and would like to repurpose it to better explain these terms it is ranking for, including updating the url to the new term the blog will be about. The plan being to 301 redirect the old url to new. In the past, I've done this with other pages, and have actually lost much of the rankings that I had earned on the original URL. What is your take on this? Maybe repurpose blog, but maintain original URL just to be on the safe side? Thanks

301 Redirect for multiple links
I just relaunched my website and changed a permalink structure for several pages where only a subdirectory name changed. What 301 Redirect code do I use to redirect the following? I have dozens of these where I need to change just the directory name from "urban-living" to "urban", and want it to catch the following all in one redirect command. Here is an example of the structure that needs to change. Old

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

301 Redirect with index.asp
I am very new to all of this so forgive the newbie questions I will get better. Ok so after starting a campaign I see that I have many issues including where some pages are being deemed as duplicate content. 1. The report says the http://lucid8.com has duplicate content on 2 other pages 2. When I look at them it shows that http://lucid8.com/index.asp and http://www.lucid8.com are duplicates. 3. Really these are the exactly the same page because the default page that is opened for www.lucid8.com http://www.lucid8.com etc always opens the index.asp page. 4. Now I read that I should do permanent redirects and how to do this via IIS and I tried to do a redirect from index.asp to www.lucid8.com but that does not work because www.lucid8.com is pointing to index.asp and so we end up in a circle. So the question is how do I get rid of these duplicate page references without causing problems. Thanks

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?

Trailing Slashes In Url use Canonical Url or 301 Redirect?
I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?

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?
