Do I need to use canonicals if I will be using 301's?

 I just took a job about three months and one of the first things I wanted to do was restructure the site. The current structure is solution based but I am moving it toward a product focus. The problem I'm having is the CMS I'm using isn't the greatest (and yes I've brought this up to my CMS provider). It creates multiple URL's for the same page. For example, these two urls are the same page: (note: these aren't the actual urls, I just made them up for demonstration purposes) http://www.website.com/home/meet-us/team-leaders/boss-man/ 
 http://www.website.com/home/meet-us/team-leaders/boss-man/bossman.cmsx(I know this is terrible, and once our contract is up we'll be looking at a different provider) So clearly I need to set up canonical tags for the last two pages that look like this: http://www.omnipress.com/boss-man" /> With the new site restructure, do I need to put a canonical tag on the second page to tell the search engine that it's the same as the first, since I'll be changing the category it's in? For Example: http://www.website.com/home/meet-us/team-leaders/boss-man/ will become http://www.website.com/home/MEET-OUR-TEAM/team-leaders/boss-man My overall question is, do I need to spend the time to run through our entire site and do canonical tags AND 301 redirects to the new page, or can I just simply redirect both of them to the new page? I hope this makes sense. Your help is greatly appreciated!!

 no what you need to do is out of the conocal URL reference whatever is going to be shown to the user as the preferable content so if the pages http://www.omnipress.com/boss-woman" /> and next pages ">http://www.omnipress.com/boss-man" /> you will of course need 301 redirect as usual and anyone that tells you rel="canonical is not important does not understand much about SEO and that's not a sly on anyone. rel="canonical Tells Google where the original pages are it no matter what helps you immensely who searc it on SEOmoz see what Rand has to say or we could just look at this link that claims it's the most important advancement in SEO since site maps so please do use a canonical-url-tag http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps here is exactly how to implement them and I wish you all the best. http://www.metatags.org/rel_canonical Sincerely, Thomas

 Hi, Canonical tag is only required if the search engines are able to access both the pages. There is no need to apply canonical tag as long as the duplicate pages are being redirected to the new/original page. As you've specifically mentioned to Google that these page do not exist anymore and I've created a new page for all these pages, and now you want your visitors/search engines to visit the new page which doesn't have any duplicate entry. Canonical tag only works if you're running a - multilingual website or
- you're using some query strings for tacking purpose
- you've multiple copies of the one page and those page can not be deleted.
 If you're sure that after 301 redirect there will not be any duplicate entry for the page, you don't need to apply canonical tag. Hope it helps

 If your using a 301 redirect, there is no need to use the Rel=canonical tag. However, I would like to point out that the rel=canonical tag is basically made for this type of situation where your CMS is creating multiples of the same page. So adding a rel=canonical tag looks to be exactly what you’re looking for.

 You only need to use a 301. Ps. Your links are going to 404 pages

 It depends, Doing a 301 will transfer the search engine/user from Page A to Page B which is fine. However, if Page B and Page C have a similar URL structure like the first example you gave I would recommend using a canonical tag. I would recommend using a canonical tag in any case, to let the search engine spider know which page you want it to crawl. If the content/URL is very similar on two pages or more I would highly recommend it to avoid duplication.

		Over-optimizing Internal Linking: Is this real and, if so, what's the happy medium?
 I have heard a lot about having a solid internal linking structure so that Google can easily discover pages and understand your page hierarchies and correlations and equity can be passed. Often, it's mentioned that it's good to have optimized anchor text, but not too optimized. You hear a lot of warnings about how over-optimization can be perceived as spammy: https://neilpatel.com/blog/avoid-over-optimizing/ But you also see posts and news like this saying that the internal link over-optimization warnings are unfounded or outdated: Intermediate & Advanced SEO | | SearchStan
 https://www.seroundtable.com/google-no-internal-linking-overoptimization-penalty-27092.html So what's the tea? Is internal linking overoptimization a myth? If it's true, what's the tipping point? Does it have to be super invasive and keyword stuffy to negatively impact rankings? Or does simple light optimization of internal links on every page trigger this?1

		Can subdomains hurt your primary domain's SEO?
 Our primary website https://domain.com has a subdomain https://subDomain.domain.com and on that subdomain we have a jive-hosted community, with a few links to and fro. In GA they are set up as different properties but there are many SEO issues in the jive-hosted site, in which many different people can create content, delete content, comment, etc. There are issues related to how jive structures content, broken links, etc. My question is this: Aside from the SEO issues with the subdomain, can the performance of that subdomain negatively impact the SEO performance and rank of the primary domain? I've heard and read conflicting reports about this and it would be nice to hear from the MOZ community about options to resolve such issues if they exist. Thanks.

		Old URL that has been 301'd for months appearing in SERPs
 We created a more keyword friendly url with dashes instead of underscores in December. That new URL is in Google's Index and has a few links to it naturally. The previous version of the URL (with underscores) continues to rear it's ugly head in the SERPs, though when you click on it you are 301'd to the new url. The 301 is implemented correctly and checked out on sites such as http://www.redirect-checker.org/index.php. Has anyone else experienced such a thing? I understand that Google can use it's discretion on pages, title tags, canonicals, etc.... But I've never witnessed them continue to show an old url that has been 301'd to a new for months after discovery or randomly. Intermediate & Advanced SEO | | seoaustin0

		Ranking 1st for a keyword - but when 's' is added to the end we are ranking on the second page
 Hi everyone - hope you are well. I can't get my head around why we are ranking 1st for a specific keyword, but then when 's' is added to the end of the keyword - we are ranking on the second page. What could be the cause of this? I thought that Google would class both of the keywords the same, in this case, let's say the keyword was 'button'. We would be ranking 1st for 'button', but 'buttons' we are ranking on the second page. Any ideas? - I appreciate every comment. Intermediate & Advanced SEO | | Brett-S0

		Magento: Should we disable old URL's or delete the page altogether
 Our developer tells us that we have a lot of 404 pages that are being included in our sitemap and the reason for this is because we have put 301 redirects on the old pages to new pages. We're using Magento and our current process is to simply disable, which then makes it a a 404. We then redirect this page using a 301 redirect to a new relevant page. The reason for redirecting these pages is because the old pages are still being indexed in Google. I understand 404 pages will eventually drop out of Google's index, but was wondering if we were somehow preventing them dropping out of the index by redirecting the URL's, causing the 404 pages to be added to the sitemap. My questions are: 1. Could we simply delete the entire unwanted page, so that it returns a 404 and drops out of Google's index altogether? 2. Because the 404 pages are in the sitemap, does this mean they will continue to be indexed by Google? Intermediate & Advanced SEO | | andyheath0

		Block in robots.txt instead of using canonical?
 When I use a canonical tag for pages that are variations of the same page, it basically means that I don't want Google to index this page. But at the same time, spiders will go ahead and crawl the page. Isn't this a waste of my crawl budget? Wouldn't it be better to just disallow the page in robots.txt and let Google focus on crawling the pages that I do want indexed? In other words, why should I ever use rel=canonical as opposed to simply disallowing in robots.txt? Intermediate & Advanced SEO | | YairSpolter0

		Will Google View Using Google Translate As Duplicate?
 If I have a page in English, which exist on 100 other websites, we have a case where my website has duplicate content. What if I use Google Translate to translate the page from English to Japanese, as the only website doing this translation will my page get credit for producing original content? Or, will Google view my page as duplicate content, because Google can tell it is translated from an original English page, which runs on 100+ different websites, since Google Translate is Google's own software?
