Attribution of port number to canonical links...ok?
-
Hi all
A query has recently been raised internally with regard to the use of canonical links. Due to CMS limitations with a client who's CMS is managed by a third party agency, canonical links are currently output with the port number attributed, e.g.
...as opposed to the correct absolute URL:
Note port number are not attributed to the actual page URLs. We have been advised that this canonical link functionality cannot be amended at present. My personal interpretation of canonical link requirements is that such a link should exactly match the absolute URL of the intended destination page, my query is does this extend to the attribution of port number to URLs. Is the likely impact of the inclusion of such potentially incorrect URLs likely to be the same as purely incorrect canonical links.
Thanks

I can't imagine why any CMS would be designed that way or, why, from a coding standpoint, it would be hard to remove. I try not to second-guess third-party providers (because I've been in their shoes), but that sounds like borderline BS to me. "Can't fix it" is far too often "Don't want to fix it".
My gut feeling is that Google will ignore a standard port 80, and will only index the port if it's non-default or if the entire site (including internal links) is explicitly using the port. By adding that canonical, though, you're definitely sending a mixed signal, and there is risk. I've never seen this actual situation in play, so I can only speculate.
Is it possible to remove the canonical tags on these pages and using 301-redirects or some other approach? Unfortunately, a lot of this depends on how the pages actually resolve and what other signals are in play. It's a bit tough to tell without looking at the specific site.

My guess is that the port number version of the URL is what will start appearing in SERPs.

I would remove the canonical tag if possible.

Should I apply Canonical Links from my Landing Pages to Core Website Pages?
I am working on an SEO project for the website: https://wave.com.au/ There are some core website pages, which we want to target for organic traffic, like this one: https://wave.com.au/doctors/medical-specialties/anaesthetist-jobs/ Then we have basically have another version that is set up as a landing page and used for CPC campaigns. https://wave.com.au/anaesthetists/ Essentially, my question is should I apply canonical links from the landing page versions to the core website pages (especially if I know they are only utilising them for CPC campaigns) so as to push link equity/juice across? Here is the GA data from January 1 - April 30, 2019 (Behavior > Site Content > All Pages😞

Phone number link / critical crawler issue
I've got 15 critical crawler issues coming up, all of which are ( tel: )links to the contact phone number. As this is a taxi firm, these links are pretty vital to customer conversion. Should I worry about these issues from an SEO perspective? If so, is there anything I can do about it?

Absolute vs. Relative Canonical Links
Hi Moz Community, I have a client using relative links for their canonicals (vs. absolute) Google appears to be following this just fine, but bing, etc. are still sending organic traffic to the non-canonical links. It's a drupal setup. Anyone have advice? Should I recommend that all canonical links be absolute? They are strapped for resources, so this would be a PITA if it won't make a difference. Thanks

If I nofollow outbound external links to minimize link juice loss > is it a good/bad thing?
OK, imagine you have a blog, and you want to make each blog post authoritative so you link out to authority relevant websites for reference. In this case it is two external links per blog post, one to an authority website for reference and one to flickr for photo credit. And one internal link to another part of the website like the buy-now page or a related internal blog post. Now tell me if this is a good or bad idea. What if you nofollow the external links and leave the internal link untouched so all internal links are dofollow. The thinking is this minimizes loss of link juice from external links and keeps it flowing through internal links to pages within the website. Would it be a good idea to lay off the nofollow tag and leave all as do follow? or would this be a good way to link out to authority sites but keep the link juice internal? Your thoughts are welcome. Thanks.

URL Value: Menu Links vs Body Content Links
Hi All, I'm a little confused. I have read a number of articles from authority sites that give mixed signals over the importance of menu links vs body content links. It is suggested that whilst all menu links spread link juice equally, Google does not see them as favourably. Inserting a link within the body will add more link juice value to the desired page. Any thoughts would be appreciated. Thanks Mark

Link Research Tools - Detox Links
Hi, I was doing a little research on my link profile and came across a tool called "LinkRessearchTools.com". I bought a subscription and tried them out. Doing the report they advised a low risk but identified 78 Very High Risk to Deadly (are they venomous?) links, around 5% of total and advised removing them. They also advised of many suspicious and low risk links but these seem to be because they have no knowledge of them so default to a negative it seems. So before I do anything rash and start removing my Deadly links, I was wondering if anyone had a). used them and recommend them b). recommend detoxing removing the deadly links c). would there be any cases in which so called Deadly links being removed cause more problems than solve. Such as maintaining a normal looking profile as everyone would be likely to have bad links etc... (although my thinking may be out on that one...). What do you think? Adam

Canonical Tag and Affiliate Links
Hi! I am not very familiar with the canonical tag. The thing is that we are getting traffic and links from affiliates. The affiliates links add something like this to the code of our URL: www.mydomain.com/category/product-page?afl=XXXXXX At this moment we have almost 2,000 pages indexed with that code at the end of the URL. So they are all duplicated. My other concern is that I don't know if those affilate links are giving us some link juice or not. I mean, if an original product page has 30 links and the affiliates copies have 15 more... are all those links being counted together by Google? Or are we losing all the juice from the affiliates? Can I fix all this with the canonical tag? Thanks!
