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.

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 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

Product Variations (rel=canonical or 301) & Duplicate Product Descriptions
Hi All, Hoping for a bit of advice here please, I’ve been tasked with building an e-commerce store and all is going well so far. We decided to use Wordpress with Woocommerce as our shop plugin. I’ve been testing the CSV import option for uploading all our products and I’m a little concerned on two fronts: - Product Variations Duplicate content within the product descriptions **Product Variations: - ** We are selling furniture that has multiple variations (see list below) and as a result it creates c.50 product variations all with their own URL’s. Facing = Left, Right Leg style = Round, Straight, Queen Ann Leg colour = Black, White, Brown, Wood Matching cushion = Yes, No So my question is should I 301 re-direct the variation URL’s to the main product URL as from a user perspective they aren't used (we don't have images for each variation that would trigger the URL change, simply drop down options for the user to select the variation options) or should I add the rel canonical tag to each variation pointing back to the main product URL. **Duplicate Content: - ** We will be selling similar products e.g. A chair which comes in different fabrics and finishes, but is basically the same product. Most, if not all of the ‘long’ product descriptions are identical with only the ‘short’ product descriptions being unique. The ‘long’ product descriptions contain all the manufacturing information, leg option/colour information, graphics, dimensions, weight etc etc. I’m concerned that by having 300+ products all with identical ‘long’ descriptions its going to be seen negatively by google and effect the sites SEO. My question is will this be viewed as duplicate content? If so, are there any best practices I should be following for handling this, other than writing completely unique descriptions for each product, which would be extremely difficult given its basically the same products re-hashed. Many thanks in advance for any advice.

Best Practice on 301 Redirect - Images
We have two sites that sell the same products. We have decided to retire one of the sites as we'd like to focus on one property. I know best practice is to redirect apples to apples, which in our case is easily done since the sites sold the same thing. www.SiteABC.com/ProductA can be redirected to www.SiteXYZ.com/ProductA. My question is how far does that thinking go regarding images? Each product has a main product page, of course, and then up to 6 images in some cases. Is it necessary to redirect www.SiteABC.com/ProductA-Image1.jpg to www.SiteXYZ.com/ProductA-Image1.jpg? Or can they all be redirected to just the product page?

Loss of search engine positions after 301 redirect - what went wrong?!?
Hi Guys After adhering to the On Page optimisation suggestions given by SEOmoz, we redirected some of old urls to new ones. We set 301 redirects from the old pages to new on a page by page basis but our search engine ranking subsequently fell off the radar and lost PR. We confirmed redirection with fiddler and it shows 301 permanent redirect on every page as expected. To manage redirection using a common code logic we executed following: In Http module, using “rewrite path” we route “all old page requests” to a page called “redirect.aspx? oldpagename =[oldpagename]”. This happens at server side. In redirect.aspx we are redirecting from old page to new page using 301 permanent redirect. In the browser, when old page is requested, it will 301 redirect to new page. In hope we and others can learn from our mistakes - what did we do wrong ?!? Thanks in advance. Dave - www.paysubsonline.com
