Duplicate content issue with trailing / ?
-
Hi ,I did a SEOmoz Crawl Test and found most pages show twice, for example:
A: www.website.com/index.php/dog/walk
B: www.website.com/index.php/dog/walk/
I've checked Google Analytics and 90% of organic search traffic arrives on the URLs with the trailing slash (B).
Question 1: Can I assume I've a duplicate content problem?
Question 2: Is it best to do 301 redirects from the 'non trailing slash' pages to the 'trailing slash pages'?
Question 3: For some reason every web page has a '/index.php' in it (see A&B) above. No idea why. Should it be a SEO concern?
Kind regards and thank you in advance

Hi Nigel
You only need to 301 one of the pages, 301 is indicating a permanent move, so in the case you outlined above,
I would 301, A to B the decisions to use B was based soly off the value of the url you indicated. If for any reason you prefer the url's not use trailing slash then use A.
It also would not hurt to add a canonical tag to B
To be clear here, whether you use
website.com/index.php/dog/walk
or
website.com/index.php/dog/walk/
Does not matter as far as SEO is concerned, I would make my decision based off of which url has the highest position in Google, and be consistent with this method throughout my site.
Hope that helps,

Hi Irving
Thank you for your reply. You mention a good point regarding the sitemap.xml!
If I was to 301redirect pages A & B to a new page eg www.website.com/dog/walk/ then how would I also canonical A & B to the new page?
Surely once I have 301'd the A & B pages will be dead and redirecting traffic to the new page.
Kind regard and my apologies for any confusion.

Yes, index.php should never show so 301 that plus the trailing slash to remove it
Ddefinitely canonical all of the pages to have the URL without the trailing slash
Make sure your sitemap xml files and internal linking structure does not have the trailing slash. if they do,, then fix them to reflect the proper URL

Thank you Highland & Donford.
Re my 3rd question, can I just clarify, should I now 301 redirect both A & B URLs to a new URL say www.website/com/dog/walk ?
Many thanks!

Question 1: Can I assume I've a duplicate content problem?
-YesQuestion 2: Is it best to do 301 redirects from the 'non trailing slash' pages to the 'trailing slash pages'?
-Yes 301 is best, barring that use rel="canonical" on the page you want to indexQuestion 3: For some reason every web page has a '/index.php' in it (see A&B) above. No idea why. Should it be a SEO concern?
-Yes, this is a concern, use the same method to deal with the problem. Directories on the server side are usually assumed to have an index, if not the server can choose what to display, this can be very bad sometimes. As such most CMS content management systems fix the problem by generating content for the index.php or .html pages. However, there can be duplicate content issues since there are 2 urls with the same content, use 301 to get rid of the index.php at directory levels, or use canonical tags.
Hope that helps,
Don

1. Google can generally tell the difference between pages that have syntactically similar URLs but it's considered a best practice to not make any engine do any guesswork whenever possible.
2. I would 301 one version just for uniformity but you should be fine as-is right now.
3. There's nothing wrong with that being in the URL. Google sees it as part of the URL and nothing more. I don't consider it aesthetic or user friendly but that's a different matter.

Duplicate content question
Hey Mozzers! I received a duplicate content notice from my Cycle7 Communications campaign today. I understand the concept of duplicate content, but none of the suggested fixes quite seems to fit. I have four pages with HubSpot forms embedded in them. (Only two of these pages have showed up so far in my campaign.) Each page contains a title (Content Marketing Consultation, Copywriting Consultation, etc), plus an embedded HubSpot form. The forms are all outwardly identical, but I use a separate form for each service that I offer. I’m not sure how to respond to this crawl issue: Using a 301 redirect doesn’t seem right, because each page/form combo is independent and serves a separate purpose. Using a rel=canonical link doesn’t seem right for the same reason that a 301 redirect doesn’t seem right. Using the Google Search Console URL Parameters tool is clearly contraindicated by Google’s documentation (I don’t have enough pages on my site). Is a meta robots noindex the best way to deal with duplicate content in this case? Thanks in advance for your help. AK

Value in Consolidating Similar Sites / Duplicate Content for Different URLs
We have 5 ecommerce sites: one company site with all products, and then four product-specific sites with relevant URL titles and products divided up between them (www.companysite.com, www.product1.com, www.product2.com, etc). We're thinking of consolidating the smaller sites into our most successful site (www.product1.com) in order to save management time and money, even though I hate to lose the product-specific URLs in search results. Is this a wise move? If we proceed, all of the products will be available on both our company site and our most successful site (www.company.com & www.product1.com). This would unfortunately give us two sites of duplicate content, since the products will have the same pictures, descriptions, etc. The only difference would be the URL. Would we face penalties from Google, even though it would make sense to continue to carry our products on our company site?

Image centric site and duplicate content issues
We have a site that has very little text, the main purpose of the site is to allow users to find inspiration through images. 1000s of images come to us each week to be processed by our editorial team, so as part of our process we select a subset of the best images and process those with titles, alt text, tags, etc. We still host the other images and users can find them through galleries that link to the process and unprocessed image pages. Due to the lack of information on the unprocessed images, we are having lots of duplicate content issues (The layout of all the image pages are the same, and there isn't any unique text to differentiate the pages. The only changing factor is the image itself in each page) Any suggestions on how to resolve this issue, will be greatly appreciated.

404 and Duplicate Content.
I just submitted my first campaign. And it's coming up with a LOT of errors. Many of them I feel are out of my control as we use a CMS for RV dealerships. But I have a couple of questions. I got a 404 error and SEO Moz tells me the link, but won't tell me where that link originated from, so I don't know where to go to fix it. I also got a lot of duplicate content, and it seems a lot of them are coming from "tags" on my blog. Is that something I should be concerned about? I will have a lot more question probably as I'm new to using this tool Thanks for the responses! -Brandon here is my site: floridaoutdoorsrv.com I welcome any advice or input!

How can something be duplicate content of itself?
Just got the new crawl report, and I have a recurring issue that comes back around every month or so, which is that a bunch of pages are reported as duplicate content for themselves. Literally the same URL: http://awesomewidgetworld.com/promotions.shtml is reporting that http://awesomewidgetworld.com/promotions.shtml is both a duplicate title, and duplicate content. Well, I would hope so! It's the same URL! Is this a crawl error? Is it a site error? Has anyone seen this before? Do I need to give more information? P.S. awesomewidgetworld is not the actual site name.

Squarespace Duplicate Content Issues
My site is built through squarespace and when I ran the campaign in SEOmoz...its come up with all these errors saying duplicate content and duplicate page title for my blog portion. I've heard that canonical tags help with this but with squarespace its hard to add code to page level...only site wide is possible. Was curious if there's someone experienced in squarespace and SEO out there that can give some suggestions on how to resolve this problem? thanks
