Rel canonical between mirrored domains
-
Hi all & happy new near!
I'm new to SEO and could do with a spot of advice:
I have a site that has several domains that mirror it (not good, I know...) So www.site.com, www.site.edu.sg, www.othersite.com all serve up the same content. I was planning to use rel="canonical" to avoid the duplication but I have a concern:
Currently several of these mirrors rank - one, the .com ranks #1 on local google search for some useful keywords. the .edu.sg also shows up as #9 for a dirrerent page. In some cases I have multiple mirrors showing up on a specific serp.
I would LIKE to rel canonical everything to the local edu.sg domain since this is most representative of the fact that the site is for a school in Singapore but...
-The .com is listed in DMOZ (this used to be important) and none of the volunteers there ever respoded to requests to update it to the .edu.sg
-The .com ranks higher than the com.sg page for non-local search so I am guessing google has some kind of algorithm to mark down obviosly local domains in other geographic locationsAny opinions on this? Should I rel canonical the .com to the .edu.sg or vice versa?
I appreciate any advice or opinion before I pull the trigger and end up shooting myself in the foot!
Best regards from Singapore!

Wow - that's a huge impact. It's hard for me to believe this one change would have such an impact, but hopefully these new numbers stick.

Hi Dr. Peter,
Just thought I would share the initial results of your suggestion because they appear to be so dramatic!
I put it a rel=alternate tag on every page indicating the .edu.sg version of the URL for "en-sg" and the com version of the url for "en".
From MozAnalytics: Before
Rank 1-3: 4 keywords
Rank 4-10: 21 keywords
Rank 11-20: 3 keywords
Rank 21-50: 2 keywords
Rank 51+: 216 keywordsFrom MozAnalytics: After
Rank 1-3: 50 keywords!!!
Rank 4-10: 19 keywords
Rank 11-20: 3 keywords
Rank 21-50: 13 keywords
Rank 51+: 167 keywordsThat's pretty crazy in under a week - Not sure if its 'real' since I never personally went to check rankings on these keywords, but wow! If the MozAnalytics information is correct I am blown away! Unfortunately its for a niche site in a tiny market so its not going to lead to fame and riches, but its still an amazing result!
Thanks so much for the great advice
Alex

Happy to help - hope it does the trick.

Fantastic response Dr. Peter! Thanks for taking the time to explain and to suggest the rel="alternate" tag which I have now implemented in a little experiment.
I very much enjoy your posts on the moz blog and thank you for all the indirect help they have given us in the past.
Best regards,
Alex

I'm not sure there's a one-sized-fits-all answer. If the .com is more geared to an audience outside of Singapore, and the .edu.sg site is more geared to the local audience you could set a region and/or language with rel="alternate" hreflang:
https://support.google.com/webmasters/answer/189077?hl=en
This is a bit more subtle canonicalization signal that Google can use to sort out sites with language and/or regional copies (the regional aspect may be relevant even if both sites are in english).
The next question would be: where does your traffic come from? If you want to consolidate, but most of your traffic is coming from outside of Singapore, then I'd probably stick with the .com - it still has a "generic" status. The .edu.sg may rank more strongly in Singapore but fall off everywhere else.
I wouldn't worry much about the DMOZ link, especially if you have a solid link profile. DMOZ links have gotten buried over the years and typically don't carry nearly the value most people think. At some point, they could be a solid boost to a new site with a small link profile, but I think even those days are well behind us.

Moving Shopify from a Sub Domain to the Full Domain
Apologies if this has been asked before. Currently we have a Shopify shop on a subdomain shop.lucybee.com a blog on subdomain blog.lucybee.com and the full domain of course. We'd now like to move everything onto Shopify on the full domain. Therefore the blog rolls into Shopify. We'll manually move pages into Shopify. Any advice or links to resources on how to manage would be gratefully received. Thank you , Jim

Robots and Canonicals on Moz
We noticed that Moz does not use a robots "index" or "follow" tags on the entire site, is this best practice? Also, for pagination we noticed that the rel = next/prev is not on the actual "button" rather in the header Is this best practice? Does it make a difference if it's added to the header rather than the actual next/previous buttons within the body?

Buying Expired Domains
Recently i was looking to buy some good quality Expired Domains. But while performing site and links query on such domains in google, none of the domains are showing any links or pages indexed in Google but the same domains are showing hundreds of links in opensiteexplorer for that domains. So does Google has started devaluing expired domains or will expired domains recover all their rankings after re registration by us.

Domain authority not showing on root domain?
I was going through our site earlier w/ the mozBar (still learning the tools, new here) and saw the attached image. There were far more links to the subdomain (#s on the left) than the root domain (#s on right). This is strange to me, because we are not using any subdomains. All links point to either our root domain or subfolders off our root domain. Is this hurting our ranking for the root domain? Not sure what's up with this. Zz9j0.jpg

Keyword in Domain or not?
My on page optimization grade is an "A" with the following factors; Factor Overview <dl class="scoreboard clearfix"> <dt>Critical Factors</dt> <dd>4 / 4</dd> <dt>High Importance Factors</dt> <dd>7 / 7</dd> <dt>Moderate Importance Factors</dt> <dd>8 / 9</dd> <dt>Low Importance Factors</dt> <dd>11 / 11</dd> <dt>Optional Factors</dt> <dd>5 / 5</dd> </dl> The main thing I appear to be missing is keywords in my URL. How truly important is that in today's SEO world and how much time or ranking would be lost if I do not have control to change the external links to my website if I decided to migrate to a keyword relevant url?

Accidently did a 301 redirect on root domain and lost domain keyword position
I just bought a domain about a week ago and instantly ranked number 4 for for my keywords with the domain keyword bonus. I created a landing page off the root of my domain while I'm building out my main site. I accidentally did a 301 redirect instead of a 302 from my root to my landing paging and this resulted in me losing my position and only being about to find my domain in the google if I searched for my domain specifically. Anyway to regain my original position? I have removed the redirect. Have I been put in the sandbox?
