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.

Is it ok to repeat a (focus) keyword used on a previous page, on a new page?
I am cataloguing the pages on our website in terms of which focus keyword has been used with the page. I've noticed that some pages repeated the same keyword / term. I've heard that it's not really good practice, as it's like telling google conflicting information, as the pages with the same keywords will be competing against each other. Is this correct information? If so, is the alternative to use various long-winded keywords instead? If not, meaning it's ok to repeat the keyword on different pages, is there a maximum recommended number of times that we want to repeat the word? Still new-ish to SEO, so any help is much appreciated! V.

Can I add external links to my sitemap?
Hi, I'm integrating with a service that adds 3rd-party images/videos (owned by them, hosted on their server) to my site. For instance, the service might have tons of pictures/videos of cars; and then when I integrate, I can show my users these pictures/videos about cars I might be selling. But I'm wondering how to build out the sitemap--I would like to include reference to these images/videos, so Google knows I'm using lots of multimedia. How's the most white-hat way to do that? Can I add external links to my sitemap pointing to these images/videos hosted on a different server, or is that frowned upon? Thanks in advance.

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.

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.

Are there any negative effects to using a 301 redirect from a page to another internal page?
For example, from http://www.dog.com/toys to http://www.dog.com/chew-toys. In my situation, the main purpose of the 301 redirect is to replace the page with a new internal page that has a better optimized URL. This will be executed across multiple pages (about 20). None of these pages hold any search rankings but do carry a decent amount of page authority.

Are duplicate links on same page alright?
If I have a homepage with category links, is it alright for those category links to appear in the footer as well, or should you never have duplicate links on one page? Can you please give a reason why as well? Thanks!
