Do I need to use rel="canonical" on pages with no external links?
-
I know having rel="canonical" for each page on my website is not a bad practice... but how necessary is it for pages that don't have any external links pointing to them?
I have my own opinions on this, to be fair - but I'd love to get a consensus before I start trying to customize which URLs have/don't have it included.
Thank you.

This is also advised as a part of the on page optimization within the Moz grading system
"Although the canonical URL tag is generally thought of as a way to solve duplicate content problems, it can be extremely wise to use it on every (unique) page of a site to help prevent any query strings, session IDs, scraped versions, licensing deals or future developments to potentially create a secondary version and pull link juice or other metrics away from the original. We believe the canonical URL tag is a best practice to help prevent future problems, even if nothing is specifically duplicate/problematic today."

It's best practice to put canonicals on every page of your site, so that Google never gets confused by things like URL parameters. This can usually be automated by most modern CMSs.

The rel="canonical" was introduced to avoid duplicate content issues. It has nothing to do with links, internal or external.
You use rel="canonical" to tell search engines which version of a page you prefer to be indexed.If you prefer to tell nothing, or if there is no way a page may get indexed with a different URL then you don't need to use rel="canonical".
You are saying that your page has no external links pointing to it - but how can you control that? I may find your page, like it and link to it! This is how backlinks are supposed to work.
As you probably know each url can we written in different ways and still point to the same content. What if you prefer your page to be indexed as http://www.yourdomain.com/yourpage and I instead link to http://www.yourdomain.com/yourpage/ (note the ending /)? In these cases using rel="canonical" may help not losing any link juice.
I hope this helps.

The canonical tag is unnecessary if you don't have problems with URL variations (tracking parameters, session ids, etc). Don't just think about external links though, if your own CMS or internal linking structure links to the same pages in different ways, the canonical tag can be a patch while you work on a development fix.
All that being said, I'm a fan of having it on every page.

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😞

Using "nofollow" internally can help with crawl budget?
Hello everyone. I was reading this article on semrush.com, published the last year, and I'd like to know your thoughts about it: https://www.semrush.com/blog/does-google-crawl-relnofollow-at-all/ Is that really the case? I thought that Google crawls and "follows" nofollowed tagged links even though doesn't pass any PR to the destination link. If instead Google really doesn't crawl internal links tagged as "nofollow", can that really help with crawl budget?

Adding a Canonical Tag to each page referencing itself?
Hey Mozers! I've noticed that on www.Zappos.com they have a Canonical tag on each page referencing it self. I have heard that this is a popular method but I dont see the point in canon tagging a page to its self. Any thoughts?

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.

Is it a bad idea to have a "press" page and link to press mentions of our company?
We've recently been getting quite a bit of press. Would it be wise to create a "press" page and link to mentions of us or would this devalue the links on the press pages as Google may think they reciprocal?

100 + links on a scrolling page
Can you add more than 100 links on your webpage If you have a webpage that adds more content from a database as a visitor scrolls down the page. If you look at the page source the 100 + links do not show up, only the first 20 links. As you scroll down it adds more content and links to the bottom of the page so its a continuos flowing page if you keep scrolling down. Just wanted to know how the 100 links maximum fits into this scenario ?

How to properly link to products from category pages?
Hi All, We have an e-commerce website and the category pages are built so that there is a product image and below it there is the title. Both the image and the title are in a href (each on its own). I encountered the following unfinished discussion here at MOZ:
Intermediate & Advanced SEO | | BeytzNet
http://www.seomoz.org/q/how-to-optimize-achor-text-links-on-ecommerce-category-page#post-93758 The discussion states that its improper. The question is - if it is wrong then why? (maybe because Google will give its weight to the image anchor instead of the text anchor since it is higher in the page). The other question is how to resolve the matter?
Should I add nofollow to the image href? Thanks0 -
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!
