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.

Canonical Chain
This is quite advanced so maybe Rand can give me an answer? I often have seen questions surrounding a 301 chain where only 85% of the link juice is passed on to the first target and 85% of that to the next one, up to three targets. But how about a canonical chain? What do I mean by this:? I have a client who sells lighting so I will use a real example (sans domain) I don't want 'new-product' pages appearing in SERPS. They dilute link equity for the categories they replicate and often contain identical products to the main categories and subcategories. I don't want to no index them all together I'd rather tell Google they are the same as the higher category/sub category. (discussion whether a noindex/follow tag would be better?) If I canonicalize new-products/ceiling-lights-c1/kitchen-lighting-c17/kitchen-ceiling-lights-c217 to /ceiling-lights-c1/kitchen-lighting-c17/kitchen-ceiling-lights-c217 I then subsequently discover that everything in kitchen-ceiling-lights-c217 is already in /kitchen-lighting-c17 and I decide to canonicalize those two - so I place a /kitchen-lighting-c17 canonical on /kitchen-ceiling-lights-c217. Then what happens to the new-products canonical? Is it the same rule - does it pass 85% of link equity back to the non new-product URL and 85% of that back to the category? does it just not work? or should I do noindexi/follow Now before you jump in: Let's assume these are done over a period of time because the obvious answer is: Canonicalize both back to /ceiling-lights-c1/kitchen-lighting-c17 I know that and that is not what I am asking. What if they are done in a sequence what is the real result? I don't want to patronise anyone but please read this carefully before giving an answer. Regards Nigel Carousel Projects.

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

Does Disavowing Links Negate Anchor Text, or Just Negates Link Juice
I'm not so sure that disavowing links also discounts the anchor texts from those links. Because nofollow links absolutely still pass anchor text values. And disavowing links is supposed to be akin to nofollowing the links. I wonder because there's a potential client I'm working on an RFP for and they have tons of spammy directory links all using keyword rich anchor texts and they lost 98% of their traffic in Pengiun 1.0 and haven't recovered. I want to know what I'm getting into. And if I just disavow those links, I'm thinking that it won't help the anchor text ratio issues. Can anyone confirm?

Wrong titles in site links
Hello fellow marketers, I have found this weird thing with our website in the organic results. The sitelinks in the SERP shows wrong written text. As in grammatically incorrect text. My question is where does Google get the text from? It is not the page title as we can see it. kKsFv0X.png

Credit Links on Client Websites
I know there have been several people who have asked this but a lot of them were back in 2012 before many of the google changes. My question is the same though. With all the changes with Google's algorithm. Is it okay to put your link on the bottom of your clients website. Like Web Design by, etc. Part of the reason is to drive traffic but also if someone is actually interested who designed the website, they will click it. But now reading about how bad links can hurt you tremendously, it makes me second guess if this is ok. My gut feeling says, no.

Number of images on Google?
Hello here, In the past I was able to find out pretty easily how many images from my website are indexed by Google and inside the Google image search index. But as today looks like Google is not giving you any numbers, it just lists the indexed images. I use the advanced image search, by defining my domain name for the "site or domain" field: http://www.google.com/advanced_image_search and then Google returns all the images coming from my website. Is there any way to know the actual number of images indexed? Any ideas are very welcome! Thank you in advance.

Is it ok to use both 301 redirect and rel="canonical' at the same time?
Hi everyone, I'm sorry if this has been asked before. I just wasn't able to find a response in previous questions. To fix the problems in our website regarding duplication I have the possibility to set up 301's and, at the same time, modify our CMS so that it automatically sets a rel="canonical" tag for every page that is generated. Would it be a problem to have both methods set up? Is it a problem to have a on a page that is redirecting to another one? Is it advisable to have a rel="canonical" tag on every single page? Thanks for reading!
