Is this correct?

I noticed Moz using the following for its homepage
Is this best practice though? The reason I ask is that, I use and I've been reading this page by Google
http://googlewebmastercentral.blogspot.co.uk/2013/04/5-common-mistakes-with-relcanonical.html
5 common mistakes with rel=canonical
Mistake 2: Absolute URLs mistakenly written as relative URLs
The tag, like many HTML tags, accepts both relative and absolute URLs. Relative URLs include a path “relative” to the current page. For example, “images/cupcake.png” means “from the current directory go to the “images” subdirectory, then to cupcake.png.” Absolute URLs specify the full path—including the scheme like http://.
Specifying (a relative URL since there’s no “http://”) implies that the desired canonical URL is http://example.com/example.com/cupcake.html even though that is almost certainly not what was intended. In these cases, our algorithms may ignore the specified rel=canonical. Ultimately this means that whatever you had hoped to accomplish with this rel=canonical will not come to fruition.

Ow im sorry, totally mis understood - sorry if i was explaining something you understood.
Moz use
you said they use
/> i presume now you mean the / at the end of the tag.
This is an old school closing tag. HTML elements were traditionally opened and closed in HTML versions before HTML5. Normally this is done obviously with tags such the opener "
" and closer "
". However some elements dont have a seperate closing tag such as "" tags. In older html versions these were closed using the format
Missing these tags didn't used to do much as most browsers rendered the page correctly anyways, but best practice was to include the / to close elements. However with the dawn of HTML5 things changed.
HTML5 doesn't require the closing tag. Elements that used to require one now simply dont. Browsers still understand both versions absolutely fine and its kinda ok to use either. But the most modern and correct practice is to use it without.
Edit:
Racking my brain, i believe the / was added as best practice to assure compatibility with XHTML which was pegged to be the next version of HTML. When XHTML was scrapped in favour of HTML5 it changed. Somebody may correct me on this one though

Thanks, I realise the usage should be a correct relative URL or a correctly formed absolute URL. In Moz's case, they used a correctly formed absolute URL.
My question is more around...why not use "/"?

Looks fine to me, i think you misunderstand Mistake 2
They are using an absolute URL
If they did the "mistake 2" their canonical tag would look like
You canonical tags should always be absolute for good practice
is correct
or any variant of this would be wrong

Allowing correct crawlers for GeoIP Redirect
Hi All, I am working on an international site and we have started running into issues with crawlers successfully crawling the site. GeoIPEnable On Redirect one country RewriteEngine on
Intermediate & Advanced SEO | | michaelpw
RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^US$
RewriteCond %{HTTP:X-Host} !.nexcesscdn.net$ [NC]
RewriteRule ^(.)$ https://us.website.com/ [R,L] The main reason for working on a hard GEOIP redirect would be that we are unable to show certain products in certain regions, the customer should not be given the option which is best practice. Can anyone advise? Thanking in advance.0 -
H1 and Schema Codes Set Up Correctly?
Greetings: It was pointed out to me that the h1 tags on my website (www.nyc-officespace-leader.com) all had exactly the same text and that duplication may be contributing to the very low page authority for most URLs. The duplicate h1 appears in line 54-54 (see below) of the home page: www.nyc-officespace-leader.com: itemscope itemtype="http://schema.org/LocalBusiness" style="position:absolute;top:-9999em;"> <span<br>itemprop="name">Metro Manhattan Office Space</span<br> <img< p="">But the above refers to schema" so is this really duplicate H1 or is there an exception if the H1 is within a schema? Also, I was told that the company street address and city and state were set up incorrectly as part of an alt tag. However these items also appear as schema in lines 49-68 shown below: Dangerous for me to perform surgery on the code without being certain about these key items!! Could ask my developer, however they may be uncomfortable considering that they set this up in the 1st place. So the view of neutral professionals would be highly welcome! itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">

Have I set up my structured data correctly, the testing tool suggests not?
Hi, I've recently marked up some Events for a client in hope that they'll appear as rich snippets in ther SERPS. I have access to their Google Search Console so used the Data Highlighter facility to mark them up, rather than the Raven plugin available for WordPress sites like this. I completed this on 10th July and the snippets are yet to appear - I understand that this can take time and there are no guarantees - but as a novice it would be reassuring if someone can advise that I have done this correctly. We did incidentally resubmit a sitemap after completing this task, but I'm not sure if that makes any difference. I've read that it's the structured data testing tool that I need to use to test my markup, but when I input the urls below, the tool doesn't tell me a lot, which either suggests I've marked it up incorrectly, or don't know how to read it! http://www.ad-esse.com/events/19th-august-2015-reducing-costs-changing-culture-improving-services/

Correct Syntax for Meta No Index
Hi, Is this syntax ok for the bots, especially Google to pick up? Still waiting for Google to drop lots of duplicate pages caused by parameters out of the index - if there are parameters in the querystring it inserts the code above into the head. Thanks!

Correct strategy for long-tail keywords?
Hi, We are selling log houses on our website. Every log house is listed as a "product", and this "product" consists of many separate parts, that are technically also products. For example a log house product consists of doors, windows, roof - and all these parts are technically also products, having their own content pages. The question is - Should we let google index these detail pages, or should we list them as noindex? These pages have no content, only the headline, which are great for long-tail SEO. We are probably the only manufacturer in the world who has a separate page for "log house wood beam 400x400mm". But otherwise these pages are empty. My question is - what should we do? Should we let google index them all (we have over 3600 of them) and maybe try to insert an automatic FAQ section to every one of them to put more content on the page? Or will 3600 low-content pages hurt our rankings? Otherwise we are ranking quite well. Thanks, Johan
