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.

How Many Links to Disavow at Once When Link Profile is Very Spammy?
We are using link detox (Link Research Tools) to evaluate our domain for bad links. We ran a Domain-wide Link Detox Risk report. The reports showed a "High Domain DETOX RISK" with the following results: -42% (292) of backlinks with a high or above average detox risk
Intermediate & Advanced SEO | | Kingalan1
-8% (52) of backlinks with an average of below above average detox risk
-12% (81) of backlinks with a low or very low detox risk
-38% (264) of backlinks were reported as disavowed. This look like a pretty bad link profile. Additionally, more than 500 of the 689 backlinks are "404 Not Found", "403 Forbidden", "410 Gone", "503 Service Unavailable". Is it safe to disavow these? Could Google be penalizing us for them> I would like to disavow the bad links, however my concern is that there are so few good links that removing bad links will kill link juice and really damage our ranking and traffic. The site still ranks for terms that are not very competitive. We receive about 230 organic visits a week. Assuming we need to disavow about 292 links, would it be safer to disavow 25 per month while we are building new links so we do not radically shift the link profile all at once? Also, many of the bad links are 404 errors or page not found errors. Would it be OK to run a disavow of these all at once? Any risk to that? Would we be better just to build links and leave the bad links ups? Alternatively, would disavowing the bad links potentially help our traffic? It just seems risky because the overwhelming majority of links are bad.0 -
Top hierarchy pages vs footer links vs header links
Hi All, We want to change some of the linking structure on our website. I think we are repeating some non-important pages at footer menu. So I want to move them as second hierarchy level pages and bring some important pages at footer menu. But I have confusion which pages will get more influence: Top menu or bottom menu or normal pages? What is the best place to link non-important pages; so the link juice will not get diluted by passing through these. And what is the right place for "keyword-pages" which must influence our rankings for such keywords? Again one thing to notice here is we cannot highlight pages which are created in keyword perspective in top menu. Thanks

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!

Linking to URLs With Hash (#) in Them
How does link juice flow when linking to URLs with the hash tag in them? If I link to this page, which generates a pop-over on my homepage that gives info about my special offer, where will the link juice go to? homepage.com/#specialoffer Will the link juice go to the homepage? Will it go nowhere? Will it go to the hash URL above? I'd like to publish an annual/evergreen sort of offer that will generate lots of links. And instead of driving those links to homepage.com/offer, I was hoping to get that link juice to flow to the homepage, or maybe even a product page, instead. And just updating the pop over information each year as the offer changes. I've seen competitors do it this way but wanted to see what the community here things in terms of linking to URLs with the hash tag in them. Can also be a use case for using hash tags in URLs for tracking purposes maybe?

Do links to PDF's on my site pass "link juice"?
Hi, I have recently started a project on one of my sites, working with a branch of the U.S. government, where I will be hosting and publishing some of their PDF documents for free for people to use. The great SEO side of this is that they link to my site. The thing is, they are linking directly to the PDF files themselves, not the page with the link to the PDF files. So my question is, does that give me any SEO benefit? While the PDF is hosted on my site, there are no links in it that would allow a spider to start from the PDF and crawl the rest of my site. So do I get any benefit from these great links? If not, does anybody have any suggestions on how I could get credit for them. Keep in mind that editing the PDF's are not allowed by the government. Thanks.

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 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?
