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.

Using hreflang="en" instead of hreflang="en-gb"
Hello, I have a question in regard to international SEO and the hreflang meta tag. We are currently a B2B business in the UK. Our major market is England with some exceptions of sales internationally. We are wanting to increase our ranking into other english speaking countries and regions such as Ireland and the Channel Islands. My research has found regional google search engines for Ireland (google.ie), Jersey (google.je) and Guernsey (google.gg). Now, all the regions have English as one their main language and here is my questions. Because I use hreflang=“en-gb” as my site language, am I regional excluding these countries and islands? If I used hreflang=“en” would it include these english speaking regions and possible increase the ranking on these the regional search engines? Thank you,

"noindex, follow" or "robots.txt" for thin content pages
Does anyone have any testing evidence what is better to use for pages with thin content, yet important pages to keep on a website? I am referring to content shared across multiple websites (such as e-commerce, real estate etc). Imagine a website with 300 high quality pages indexed and 5,000 thin product type pages, which are pages that would not generate relevant search traffic. Question goes: Does the interlinking value achieved by "noindex, follow" outweigh the negative of Google having to crawl all those "noindex" pages? With robots.txt one has Google's crawling focus on just the important pages that are indexed and that may give ranking a boost. Any experiments with insight to this would be great. I do get the story about "make the pages unique", "get customer reviews and comments" etc....but the above question is the important question here.

Putting "noindex" on a page that's in an iframe... what will that mean for the parent page?
If I've got a page that is being called in an iframe, on my homepage, and I don't want that called page to be indexed.... so I put a noindex tag on the called page (but not on the homepage) what might that mean for the homepage? Nothing? Will Google, Bing, Yahoo, or anyone else, potentially see that as a noindex tag on my homepage?

How do I get rel='canonical' to eliminate the trailing slash on my home page??
I have been searching high and low. Please help if you can, and thank you if you spend the time reading this. I think this issue may be affecting most pages. SUMMARY: I want to eliminate the trailing slash that is appended to my website. SPECIFIC ISSUE: I want www.threewaystoharems.com to showing up to users and search engines without the trailing slash but try as I might it shows up like www.threewaystoharems.com/ which is the canonical link. WHY? and I'm concerned my back-links to the link without the trailing slash will not be recognized but most people are going to backlink me without a trailing slash. I don't want to loose linkjuice from the people and the search engines not being in consensus about what my page address is. THINGS I"VE TRIED: (1) I've gone in my wordpress settings under permalinks and tried to specify no trailing slash. I can do this here but not for the home page. (2) I've tried using the SEO by yoast to set the canonical page. This would work if I had a static front page, but my front page is of blog posts and so there is no advanced page settings to set the canonical tag. (3) I'd like to just find the source code of the home page, but because it is CSS, I don't know where to find the reference. I have gone into the css files of my wordpress theme looking in header and index and everywhere else looking for a specification of what the canonical page is. I am not able to find it. I'm thinking it is actually specified in the .htaccess file. (4) Went into cpanel file manager looking for files that contain Canonical. I only found a file called canonical.php . the only thing that seemed like it was worth changing was changing line 139 from $redirect_url = home_url('/'); to $redirect_url = home_url(''); nothing happened. I'm thinking it is actually specified in the .htaccess file. (5) I have gone through the .htaccess file and put thes 4 lines at the top (didn't redirect or create the proper canonical link) and then at the bottom of the file (also didn't redirect or create the proper canonical link) : RewriteEngine on

Why is "Noindex" better than a "Canonical" for Pagination?
"Noindex" is a suggested pagination technique here: http://searchengineland.com/the-latest-greatest-on-seo-pagination-114284, and everyone seems to agree that you shouldn't canonicalize all pages in a series to the first page, but I'd love if someone can explain why "noindex" is better than a canonical?

Canonical link vs root domain
I have a wordpress website installed on http://domain.com/home/ instead of http://domain.com - Does it matter whether I leave it that way with a canonical link from the domain.com to the domain.com/home/ or should I move the wordpress files and database to the root domain?
