Wildcard Redirects & Canonical Tags

I have an interesting situation.
Current URLs Example1:
www.domain.com/red-widgets-cid-1234.html
www.domain.com/red-widgets-cid-1234-1.html
www.domain.com/red-widgets-cid-1234-1-1.htmlCanonical on All Above URLs:
www.domain.com/red-widgets-cid-1234.htmlNew URL:
www.domain.com/red-widgets-cid-4567.htmlCurrent URLs Example2:
www.domain.com/red-widgets-cid-1234+10.html
www.domain.com/red-widgets-cid-1234+10-1.html
www.domain.com/red-widgets-cid-1234+10-1-1.htmlCanonical on All Above URLs:
www.domain.com/red-widgets-cid-1234+10.htmlNew URL:
www.domain.com/red-widgets-cid-6789.htmlCurrent URLs Example3:
www.domain.com/red-widgets-cid-1234+10+5.html
www.domain.com/red-widgets-cid-1234+10+5-1.html
www.domain.com/red-widgets-cid-1234+10+5-1-1.htmlCanonical on All Above URLs:
www.domain.com/red-widgets-cid-1234+10+5.htmlNew URL:
www.domain.com/american-red-widgets-cid-6789+5.htmlI want to make sure all variations of the above URL redirect to the new URLs. However, as you see in Example 3, we are dealing with variables that are passed on. (+5 in this case).
Question 1: What wildcard 301 redirect / regular expression can I use to tackle these ?
Question 2: If we redirect www.domain.com/red-widgets-cid-1234+10+5.html to www.domain.com/red-widgets-cid-6789+5.html and www.domain.com/red-widgets-cid-6789+5.html contains the canonical tag www.domain.com/american-red-widgets-cid-6789+5.html, any concerns or red flags here ?

Hi Nakul
Here is my stab at question 1, my methodology is trial and error so if any guru's want to take another shot at it please do so. Here is a nice 301 reference page lots of examples
RewriteEngine On
RewriteRule ^(.)_red-widgets-cid-1234.html$ www.domain.com/red-widgets-cid-4567.html [R=301]
#Example 2
RewriteRule ^(.)_red-widgets-cid-1234+10.html$ www.domain.com/red-widgets-cid-6789.html [R=301]
#Example 3
RewriteRule ^(.*)_red-widgets-cid-1234+10+5.html$ www.domain.com/american-red-widgets-cid-6789+5.html [R=301,L]We use ^ to denote start of string
We use $ to denote end of string
We use (.*)_ to look for a keyword. In the examples above we are looking for what each page name has in common
We use [R=301,L] for the Last rewrite, previous rules just use [R=301]
One thing that (maybe) needed is escaping the +signs in the string so like example 3 would be
^(.*)_red-widgets-cid-1234+10+5.html$ www.domain.com/american-red-widgets-cid-6789+5.html
Also I may missed a wildcard on some of these....
^(.)_red-widgets-cid-1234+10+5(.).html$ www.domain.com/american-red-widgets-cid-6789+5.html
Question 2:
Canonical to self canonical tag is okay.
This = That and That = That ..........Okay
This = That and That = The ..........Not OkayHope that puts you on track

Hreflang and canonical tag for new country specific website - different base domain
I have a little different situation compared to most other questions which asks for hreflang and canonical tags for country specific version of websites. This is an SEO related question and I was hoping to get some insight on your recommendations. We have an existing Australian website - say - ausnight.com.au now we want to launch a UK version of this website - the domain is - uknight.co.uk please note, we are not only changing from .com.au to .co.uk.... but the base domain name as well changed - from ausnight to uknight as you can understand, the audience for both websites is different. Both websites has most pages same with same contents.... the questions I have is - Should we put canonical tag on the new website pages? If we don't put canon tag on new website pages, what is the impact on the SEO ranking of current website? I believe we need to put hreflang tag on both websites to tell google that we have another language version (en-au vs en-gb) of the same page. Is this correct?

Canonical and Alternate Advice
At the moment for most of our sites, we have both a desktop and mobile version of our sites. They both show the same content and use the same URL structure as each other. The server determines whether if you're visiting from either device and displays the relevant version of the site. We are in a predicament of how to properly use the canonical and alternate rel tags. Currently we have a canonical on mobile and alternate on desktop, both of which have the same URL because both mobile and desktop use the same as explained in the first paragraph. Would the way of us doing it at the moment be correct?

302 > 302 > 301 Redirect Chain Issue & Advice
Hi everyone, I recently relaunched our website and everything went well. However, while checking site health, I found a new redirect chain issue (302 > 302 > 301 > 200) when the user requests the HTTP and non-www version of our URL. Here's what's happening: • 302 #1 -- http://domain.com/example/ 302 redirects to http://domain.com/PnVKV/example/ (the 5 characters in the appended "subfolder" are dynamic and change each time)
Intermediate & Advanced SEO | | Andrew_In_Search_of_Answers
• 302 #2 -- http://domain.com/PnVKV/example/ 302 redirects BACK to http://domain.com/example/
• 301 #1 -- http://domain.com/example/ 301 redirects to https://www.domain.com/example/ (as it should have done originally)
• 200 -- https://www.domain.com/example/ resolves properly We're hosted on AWS, and one of my cloud architects investigated and reported GoDaddy was causing the two 302s. That's backed up online by posts like https://stackoverflow.com/questions/46307518/random-5-alpha-character-path-appended-to-requests and https://www.godaddy.com/community/Managing-Domains/My-domain-name-not-resolving-correctly-6-random-characters-are/td-p/60782. I reached out to GoDaddy today, expecting them to say it wasn't a problem on their end, but they actually confirmed this was a known bug (as of September 2017) but there is no timeline for a fix. I asked the first rep I spoke with on the phone to send a summary, and here's what he provided in his own words: From the information gathered on my end and I was able to get from our advanced tech support team, the redirect issue is in a bug report and many examples have been logged with the help of customers, but no log will be made in this case due to the destination URL being met. Most issues being logged are site not resolving properly or resolving errors. I realize the redirect can cause SEO issues with the additional redirects occurring. Also no ETA has been logged for the issue being reported. I do feel for you since I now understand more the SEO issues it can cause. I myself will keep an eye out for the bug report and see if any progress is being made any info outside of this I will email you directly. Thanks. Issue being Experienced: Domains that are set to Go Daddy forwarding IPs may sometimes resolve to a url that has extra characters appended to the end of them. Example: domain1.com forwards to http://www.domain2.com/TLYEZ. However it should just forward to http://www.domain2.com. I think this answers what some Moz users may have been experiencing sporadically, especially this previous thread: https://moz.com/community/q/forwarded-vanity-domains-suddenly-resolving-to-404-with-appended-url-s-ending-in-random-5-characters. My question: Given everything stated above and what we know about the impact of redirect chains on SEO, how severe should I rate this? I told my Director that I would recommend we move away from GoDaddy (something I don't want to do, but feel we _**have **_to do), but she viewed it as just another technical SEO issue and one that didn't necessarily need to be prioritized over others related to the relaunch. How would you respond in my shoes? On a scale of 1 to 10 (10 being the biggest), how big of a technical SEO is this? Would you make it a priority? At the very least, I thought the Moz community would benefit from the GoDaddy confirmation of this issue and knowing about the lack of an ETA on a fix. Thanks!0 -
Default Wordpress 301 Redirects of JS and CSS files. Bad for SEO & How to Fix?
Hi there: We are developers with some digital marketing expertise, but a current issue has us perplexed. An outside SEO firm has asked us to clean up a large number of 301 redirects. Most of these are 'default' Wordpress behavior that relate to calling the latest version of a JS or CSS file. For instance, a JS file is called with this: https://websitexyz.com/wp-includes/js/wp-embed.min.js?ver=4.9.1 but ultimately redirects to this: https://websitexyz.com/wp-includes/js/wp-embed.min.js. We are being asked to prevent the redirect from happening by, presumably, calling the ultimate file to begin with. The issue is that, as far as we know, there's no easy way to alter WP behavior to call the ultimate file to begin with. Does anyone have any thoughts on this? Thanks.

H Tags in Menu
Hi I am checking the H2 tags on this page https://www.key.co.uk/en/key/dollies-load-movers-door-skates I have noticed my dev team have implemented H2's on the categories in the menu. Will this completely confuse Google as to what that page is about? In my opinion those links shouldn't be heading tags at all

Are pages with a canonical tag indexed?
Hello here, here are my questions for you related to the canonical tag: 1. If I put online a new webpage with a canonical tag pointing to a different page, will this new page be indexed by Google and will I be able to find it in the index? 2. If instead I apply the canonical tag to a page already in the index, will this page be removed from the index? Thank you in advance for any insights! Fabrizio

Canonical URLs and Sitemaps
We are using canonical link tags for product pages in a scenario where the URLs on the site contain category names, and the canonical URL points to a URL which does not contain the category names. So, the product page on the site is like www.example.com/clothes/skirts/skater-skirt-12345, and also like www.example.com/sale/clearance/skater-skirt-12345 in another category. And on both of these pages, the canonical link tag references a 3rd URL like www.example.com/skater-skirt-12345. This 3rd URL, used in the canonical link tag is a valid page, and displays the same content as the other two versions, but there are no actual links to this generic version anywhere on the site (nor external). Questions: 1. Does the generic URL referenced in the canonical link also need to be included as on-page links somewhere in the crawled navigation of the site, or is it okay to be just a valid URL not linked anywhere except for the canonical tags? 2. In our sitemap, is it okay to reference the non-canonical URLs, or does the sitemap have to reference only the canonical URL? In our case, the sitemap points to yet a 3rd variation of the URL, like www.example.com/product.jsp?productID=12345. This page retrieves the same content as the others, and includes a canonical link tag back to www.example.com/skater-skirt-12345. Is this a valid approach, or should we revise the sitemap to point to either the category-specific links or the canonical links?

301 Redirects After Company Acquisition
We recently acquired a company, and now we are going to redirect all of the pages on their site to their respective pages on our site. Do we need to keep the original pages on their site active? For how long? Ideally, we would like to redirect everything and remove the old site entirely so we don't have to pay to keep hosting it. Is this possible? Thanks!
