Welcome to the Q&A Forum

So I have products appearing in several categories, all of which have the correct canonical url. But Moz is flagging up pages I never knew existed, and I don't understand why they exist at all and more so why my canonical fix isn't occurring for them, as below:

SEO Friendly URL: http://thespacecollective.com/nasa-pin-sets/nasa-shuttle-mission-pin-set-no2

Weird URL to same product: http://thespacecollective.com/index.php?route=themecontrol/product&product_id=159

Is this a developer problem rather than an SEO problem?

Apparently this didn't work. According to the Moz tool I have the same amount of duplicate title tags as before.

The main problem I have is that the most serious issues facing my site have been dealt with using Google Tags, but Moz doesn't take this into account (this has been verified by a Moz employee) so I can't get an accurate account of what crawl issues need fixing and which ones are resolved.

Does anyone know a way to make Moz Tools account for Google Tags?

Thanks Vijay, I did read this a few days ago and it wasn't helpful. All of the information was either not relevant to my situation or inconclusive.

Does anyone know how to add canonical tags to product pages in Opencart?

Is this possible to do in htaccess? If so, how specifically should it be written in?

Please do not post any links to other pages which reference generic canonical information as I've read them all and none help. I'm looking for an Opencart specific answer, or a way to do it in htaccess.

Hello Tawny,

Thank you for the response. My problem is that I don't know how to assign Canonical tags to product pages in Opencart, and anytime I ask the question I get a vague response or a link to a post with little relevance to the question. Therefore my only option has been to use the Google Tag Manager or Robots.txt, which is all good and well for Google but if I'm going to pay for Moz I want it to be accurate.

Perhaps you can answer the question nobody else has answered?

Does Moz take into account Google Tag Manager or will it keep flagging up duplicate content, etc?

Thank you for this. Google Tag Manager seems to be the most effective tool, but will the Moz Tools pick up on this or will it keep flagging my pages as Duplicate Content and so on?

So I have a seriously large amount of duplicate content problems on my Opencart site, and I've been trying to figure out the best way to fix them one by one. But is there a common, easy way of doing this? Because frankly, it is a nightmare otherwise. I bought an extension which doesn't appear to work (http://www.opencart.com/index.php?route=extension/extension/info&extension_id=20468&utm_source=ordercomplete&utm_medium=email&utm_campaign=wm), so now I'm at a loss.

I use Opencart and have found that a lot of my duplicate content (mainly from Products) which is caused by the Search function. Is there a simple way to tell Google to ignore the Search function pathway? Or is this particular action not recommended?

Here are two examples:

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

Very quick question, are rel canonical, follow/no follow tags, etc. written in the htaccess file?

Everett, you've been incredibly helpful - thank you!

Oh I understand now, thank you!

_**Re #1: **_Would putting Rel Prev on the last page in the set resolve the issue? Or is this a deeper issue within my website code which needs to be resolved by not allowing pages to be created beyond the end of the paginated set?

Thank you for the link, but I'm still unsure about these two specific issues.

Issue One:

So I have say the two below links, which are the same category but just page 1 and 2.

Page 1: http://www.interstellarstore.com/star-wars-memorabilia

Page 2: http://www.interstellarstore.com/star-wars-memorabilia/page/2/

Should Page 1 be the Canonical for all subsequent pages, or by their own rights is Page 2 and onward considered their own page? From what I understand of the former this would cause a Duplicate Title problem. The latter however would surely cause problems for Google as it would ignore all of the products on Pages 2 and onward?

Currently I have Rel Canonical and Rel Prev/Next in place, am I correct in thinking this is the correct way to do this?

Issue Two:

One of the below links is the main category (Canonical) while the other is indirect from the Brand option available on our site.

Category: http://www.interstellarstore.com/star-wars-memorabilia

Brand: http://www.interstellarstore.com/star-wars-memorabilia?page=2%2F

Am I correct in thinking that the Canonical URL displayed on the Brand page should in fact be the Category URL above?

I'm sorry for all the questions, I'm just trying to make heads to tails of the issue. Currently there are over 20,000 Duplicate Title issues and I'm thinking this may be the cause.

What do you mean by ''self-referencing Rel ="canonical" tags''?

Several thousand of these popped up on my Crawl Report and the links appear to be searches, i.e. below

902: http://thespacecollective.com/index.php?route=product/search&tag=nasa+ma-1+jacket%2F%2F%2F%2F%2F%2F%2F%2F%2F%2F%2F

403: http://thespacecollective.com/index.php?route=product/search&tag=periodic+table+tshirt%2F%2F%2F%2F%2F%2F%2F%2F%2F%2F%2F

I don't want Moz, let alone Google finding this kind of nonsensical link but I don't exactly know what the problem is or how to fix it. Am I right in thinking these are pages people have searched for? Can anyone shed light on this please?

So I've been looking over my latest crawl and two of each category appears, the only difference between them is a / at the end, i.e.

http://thespacecollective.com/space-clothing/

http://thespacecollective.com/space-clothing

One brings in a 200 code while the other brings in a 301. Given that the 301 is in place I know Google won't see it as a duplicate, but I'm curious as to why Moz picks up on this and whether or not there is an issue that needs addressing here?
