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 a page with links to all posts okay?
Hi folks. Instead of an archive page template in my theme (I have my reasons), I am thinking of simply typing the post title as and when I publish a post, and linking to the post from there. Any SEO issues that you can think of? Thanks in advance!

Does redirecting from a "bad" domain "infect" the new domain?
Hi all, So a complicated question that requires a little background. I bought unseenjapan.com to serve as a legitimate news site about a year ago. Social media and content growth has been good. Unfortunately, one thing I didn't realize when I bought this domain was that it used to be a porn site. I've managed to muck out some of the damage already - primarily, I got major vendors like Macafee and OpenDNS to remove the "porn" categorization, which has unblocked the site at most schools & locations w/ public wifi. The sticky bit, however, is Google. Google has the domain filtered under SafeSearch, which means we're losing - and will continue to lose - a ton of organic traffic. I'm trying to figure out how to deal with this, and appeal the decision. Unfortunately, Google's Reconsideration Request form currently doesn't work unless your site has an existing manual action against it (mine does not). I've also heard such requests, even if I did figure out how to make them, often just get ignored for months on end. Now, I have a back up plan. I've registered unseen-japan.com, and I could just move my domain over to the new domain if I can't get this issue resolved. It would allow me to be on a domain with a clean history while not having to change my brand. But if I do that, and I set up 301 redirects from the former domain, will it simply cause the new domain to be perceived as an "adult" domain by Google? I.e., will the former URL's bad reputation carry over to the new one? I haven't made a decision one way or the other yet, so any insights are appreciated.

Rel=canonical and internal links
Hi Mozzers, I was musing about rel=canonical this morning and it occurred to me that I didnt have a good answer to the following question: How does applying a rel=canonical on page A referencing page B as the canonical version affect the treatment of the links on page A? I am thinking of whether those links would get counted twice, or in the case of ver-near-duplicates which may have an extra sentence which includes an extra link, whther that extra link would count towards the internal link graph or not. I suspect that google would basically ignore all the content on page A and only look to page B taking into account only page Bs links. Any thoughts? Thanks!

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.

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?

Using subdomains for related landing pages?
Seeking subdomain usage and related SEO advice... I'd like to use multiple subdomains for multiple landing pages all with content related to the main root domain. Why?...Cost: so I only have to register one domain. One root domain for better 'branding'. Multiple subdomains that each focus on one specific reason & set of specific keywords people would search a solution to their reason to hire us (or our competition).

Canonical VS Rel=Next & Rel=Prev for Paginated Pages
I run an ecommerce site that paginates product pages within Categories/Sub-Categories. Currently, products are not displayed in multiple categories but this will most likely happen as time goes on (in Clearance and Manufacturer Categories). I am unclear as to the proper implementation of Canonical tags and Rel=Next & Rel=Prev tags on paginated pages. I do not have a View All page to use as the Canonical URL so that is not an option. I want to avoid duplicate content issues down the road when products are displayed in multiple categories of the site and have Search Engines index paginated pages. My question is, should I use the Rel=Next & Rel=Prev tags on paginated pages as well as using Page One as the Canonical URL? Also, should I implement the Canonical tag on pages that are not yet paginated (only one page)?

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!
