      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.

      example.com/page:80

      ...as opposed to the correct absolute URL:

      example.com/page

      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.

          https://www.google.com/search?q=inurl:%22:8080%22

          I would remove the canonical tag if possible.

            Too many on page links

            Hi I know previously it was recommended to stick to under 100 links on the page, but I've run a crawl and mine are over this now with 130+ How important is this now? I've read a few articles to say it's not as crucial as before. Thanks!

            Do I have to many internal links which is diluting link juice to less important pages

            Hello Mozzers, I was looking at my homepage and subsequent category landing pages on my on my eCommerce site and wondered whether I have to many internal links which could in effect be diluting link juice to much of the pages I need it to flow. My homepage has 266 links of which 114 (43%) are duplicate links which seems a bit to much to me. One of my major competitors who is a national company has just launched a new site design and they are only showing popular categories on their home page although all categories are accessible from the menu navigation. They only have 123 links on their home page. I am wondering whether If I was to not show every category on my homepage as some of them we don't really have any sales from and only concerntrate on popular ones there like my competitors , then the link juice flowing downwards in the site would be concerntated as I would have less links for them to flow ?... Is that basically how it works ? Is there any negatives with regards to duplicate links on either home or category landing page. We are showing both the categories as visual boxes to select and they are also as selectable links on the left of a page ? Just wondered how duplicate links would be treated? Any thoughts greatly appreciated thanks Pete

            Case Sensitive URLs, Duplicate Content & Link Rel Canonical

            I have a site where URLs are case sensitive. In some cases the lowercase URL is being indexed and in others the mixed case URL is being indexed. This is leading to duplicate content issues on the site. The site is using link rel canonical to specify a preferred URL in some cases however there is no consistency whether the URLs are lowercase or mixed case. On some pages the link rel canonical tag points to the lowercase URL, on others it points to the mixed case URL. Ideally I'd like to update all link rel canonical tags and internal links throughout the site to use the lowercase URL however I'm apprehensive! My question is as follows: If I where to specify the lowercase URL across the site in addition to updating internal links to use lowercase URLs, could this have a negative impact where the mixed case URL is the one currently indexed? Hope this makes sense! Dave

            Do 404 Pages from Broken Links Still Pass Link Equity?

            Hi everyone, I've searched the Q&A section, and also Google, for about the past hour and couldn't find a clear answer on this. When inbound links point to a page that no longer exists, thus producing a 404 Error Page, is link equity/domain authority lost? We are migrating a large eCommerce website and have hundreds of pages with little to no traffic that have legacy 301 redirects pointing to their URLs. I'm trying to decide how necessary it is to keep these redirects. I'm not concerned about the page authority of the pages with little traffic...I'm concerned about overall domain authority of the site since that certainly plays a role in how the site ranks overall in Google (especially pages with no links pointing to them...perfect example is Amazon...thousands of pages with no external links that rank #1 in Google for their product name). Anyone have a clear answer? Thanks!

            Cross linking between categories

            Is it useful for SEO to cross link between TOP level categories, let's say I have a Home page and then 2 sub categories, one about green widgets one about red widgets
            Should i create a link from the green widget to the red widget or should I leave those are separate silos ? I know that within a silo i need to cross link ( from green widget 1 to green widget 2 etc... )  but how about about from the main category to the other main category ?

            Site wide footer links vs. single link for websites we design

            I’ve been running a web design business for the past 5 years, 90% or more of the websites we build have a “web design by” link in the footer which links back to us using just our brand name or the full “web design by brand name” anchor text. I’m fully aware that site-wide footer links arent doing me much good in terms of SEO, but what Im curious to know is could they be hurting me? More specifically I’m wondering if I should do anything about the existing links or change my ways for all new projects, currently we’re still rolling them out with the site-wide footer links. I know that all other things being equal (1 link from 10 domains > 10 links from 1 domain) but is (1 link from 10 domains > 100 links from 10 domains)? I’ve got a lot of branded anchor text, which balances out my exact match and partial match keyword anchors from other link building nicely. Another thing to consider is that we host many of our clients which means there are quite a few on the same server with a shared IP. Should I? 1.) Go back into as many of the sites as I can and remove the link from all pages except the home page or a decent PA sub page- keeping a single link from the domain. 2.) Leave all the old stuff alone but start using the single link method on new sites. 3.) Scratch the site credit and just insert an exact-match anchor link in the body of the home page and hide with with CSS like my top competitor seems to be doing quite successfully. (kidding of course.... but my competitor really is doing this.)

            De-indexed Link Directory

            Howdy Guys, I'm currently working through our 4th reconsideration request and just have a couple of questions. Using Link Detox (www.linkresearchtools.com) new tool they have flagged up a 64 links that are Toxic and should be removed. After analysing them further alot / most of them are link directories that have now been de-indexed by Google. Do you think we should still ask for them to be removed or is this a pointless exercise as the links has already been removed because its been de-indexed. Would like your views on this guys.

            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!
