Rel Canonical, Follow/No Follow in htaccess?
-
Very quick question, are rel canonical, follow/no follow tags, etc. written in the htaccess file?
-
Hello,
Thank you for this information, but I have a followup question. The links you sent me refer to images and PDF's, but this isn't relative to my situation. I need to write in follow/no follow and rel=canonical via htaccess because I do not know how to do it for each individual page on my ecommerce store - additionally, htaccess is easy for me to edit if ever I need to undo something and it is nice to have everything in one place.
Can you give me a formatted example of how a follow/no follow and rel=canonical can be placed into a page via the htaccess file please? I intend on doing this for every product category, product and also my home page on my ecommerce store.
Thank you

Robots directives and rel=canonical can be assigned by .htaccess. This is a very handy way to assign noindex or rel=canonical to .pdf documents, print formats, video transcripts, etc. You can also use it to apply noindex or rel=canonical at scale. Two Moz articles (of several) that describe these are....

Hi there,
They'll be written in the source code of each applicable page.
Alternatively you can dynamically add these tags via google tag manager or within your CMS platform.
regards,
Sean

Hi
I dont think you can use rel-canonical tags in httaccess however you can define the rule for follow / no follow tag through htacess.

I was running a rapport with Sreaming Frog SEO Spider and i saw: (Tab) Directives > NOindex : https://compleetverkleed.nl/sitemap_index.xml/ is set on X-Robots-Tag 1 > noindex,follow Does this mean my sitemap isn't indexed? If anyone has some more tips for our website, feel free to give some suggestions 🙂 (Website is far from complete)

<sub>& <sup>tags, any SEO issues?</sup></sub>
Hi - the content on our corporate website is pretty technical, and we include chemical element codes in the text that users would search on (like S02, C02, etc.) A lot of times our engineers request that we list the codes correctly, with a <sub>on the last number. Question - does adding this code into the keyword affect SEO? The code would look like SO<sub>2</sub>.</sub> Thanks.

Adding Rel Canonical to multiple pages
Hi, Our CMS generates a lot of duplicate content, (Different versions of every page for 3 different font sizes). There are many other reasons why we should drop this current CMS and go with something else, and we are in the process of doing that. But for now, does anyone know how would I do the following: I've created a spreadsheet that contains the following: Column 1: rel="canonical" tag for URL Column 2: Duplicate Content URL # 1 Column 3: Duplicate Content URL # 2 Column 4: Duplicate Content URL # 3 I want to add the tag from column 1 into the head of every page from column 2,3, and 4. What would be a fast way to do this considering that I have around 1800 rows. Check the screenshot of the builtwith.com result to see more information about the website if that helps. Farris bxySL

Rel=Canonical, WWW vs non WWW and SEO
Okay so I'm a bit of a loss here. For what ever reason just about every single Wordpress site I has will turn www.mysite.com into mysite.com in the browser bar. I assume this is the rel=canonical tag at work, there are no 301s on my site. When I use the Open Site Explorer and type in www.mysite.com it shows a domain authority of around 40 and a few hundred backlinks... and then I get the message. Oh Hey! It looks like that URL redirects to XXXXXX. Would you like to see data for <a class="clickable redirects">that URL instead</a>? So if I click to see this data instead I have less than half of that domain authority and about 2 backlinks. *** Does this make a difference SEO wise? Should my non WWW be redirecting to my WWW instead because that's where the domain authority and backlinks are? Why am I getting two different domain authority and backlink counts if they are essentially the same? Or am I wrong and all that link juice and authority passes just the same?

Mod Rewrite / .htaccess avoid duplicate content
I have been searching and testing for hours but cannot find a solution. I am able to get a URL to display with out the file exntension. i.e domain.com/file instead of domain.com/file.php The problem is both versions of the URL above work, therefore a duplicate content issue. How can I force the URL with the file extension not to resolve and give a 404 error? Or just redirect to the non extension URL? IF it helps here is my code. Options +FollowSymLinks

OK to block /js/ folder using robots.txt?
I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1

http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?0 -
How to structure rel=canonical for a e commerce site
Hello, So I have searched the Q & A , Google, the zen cart forum and at this point I am looking for some one to give a concrete answer on what I should do. There is a lot of different opinions on " rel=canonical" and how to apply it , since there are many other variable in place. I have a zen cart site. I am using the latest 1.3.9 version. The default setting ( seem to me) uses the rel=canonical to point back to the specific link product or category respectively. Most of the time I have two scenarios. 1. Main category ---> Sub category----> Product 2. Main Category----> Product I'll give an example http://www.perfectindesign.com/awards ---main category http://www.perfectindesign.com/awards/acrylic-awards sub category http://www.perfectindesign.com/awards/acrylic-awards/slanted-award product (this example has three sub categories with maybe 12 products in one 4 in the second and 5 in the third) From looking at the source code for each url it the rel=canonical just points back to its own url. I want to avoid competing against my self, for the example above keyword "acrylic awards" so should the use of the re=canonical be changes site wide to have products point back to sub categories when they exist and have products point back to main categories when no sub categories exist? I am very new to seo, specifically eCommerce seo. If you have experience and have done this to a site you manage for a client or your own please advise how to proceed. Also if I'm missing some thing that will give me a better understanding of the bigger seo picture that would be great. Thanks, Yevgeny

Robots.txt and canonical tag
In the SEOmoz post - http://www.seomoz.org/blog/robot-access-indexation-restriction-techniques-avoiding-conflicts, it's being said - If you have a robots.txt disallow in place for a page, the canonical tag will never be seen. Does it so happen that if a page is disallowed by robots.txt, spiders DO NOT read the html code ?
