Uppercase/Lowercase Reading As Duplicate Permalinks
-
I cannot figure out if this is an actual SEO issue or just a crawl reader error. I use Screaming Frog to crawl my site and use their SEO features. When I look at page titles and duplicates it shows all our pages twice... some with 1 letter capitalized and the other not. I don't REALLY have duplicate permalinks do I?
I also noticed when I use some open site explorers and paste in both permalinks the specs will show for the permalink that's all lowercase but it won't find anything for the "duplicate" permalink that is capitalized.
Below I included a few screenshots.
Thank you Moz Fam!

Gaston thank you so much!!! I appreciate your extremely fast responses and help with resolving this issue!

Yeap, both are accesible, but the one with uppercase has a canonical to the other. Here there is no issue, YOAST has resolved that

Check the image attached.Relax, you are fine in this issue.
Best luck.

Yes, it seems that they are accessible...

Should I do a 301 redirect for each page? I mean... that would be like a few hundred for us... ugh. Still not sure how this happened... my developer said possibly our SEO Yoast?? A quick Google search didn't show any issues with that.

If you type those urls:
*faq.com/medicare-supplement/hawaii/
*faq.com/medicare-supplement/Hawaii/in tour site, does them load? can you access to those URLs?
IF those are accesible, then you might have a duplicate content issue.That doesn't mean that google did understand that are similar pages and leave just one of them.

There are no pages created for the permalinks that are capitalized, we did not create different URLs for these pages. We don't have any duplicate content on our website. When I put the permalink into Google it does show it capitalized in the permalink after it's loaded. Then when I put the same permalink that is not capitalized into Google it shows the same page. However, we most definitely did not create duplicate pages. So is Google seeing it as duplicate content then?

Hello there!
Technically using those capital letters create different URLs. My advise is to canonicailze those to one or 301 redirect.
Remember that having several URLs with the same content is by definition duplicate content, even if the difference between those URLs are just a Uppercase/Lowercase.Google stated that they do not care the capital letters as a ranking factor, take a look in these articles:

Best luck.

Duplicate Content through 'Gclid'
Hello, We've had the known problem of duplicate content through the gclid parameter caused by Google Adwords. As per Google's recommendation - we added the canonical tag to every page on our site so when the bot came to each page they would go 'Ah-ha, this is the original page'. We also added the paramter to the URL parameters in Google Wemaster Tools. However, now it seems as though a canonical is automatically been given to these newly created gclid pages; below https://www.google.com.au/search?espv=2&q=site%3Awww.mypetwarehouse.com.au+inurl%3Agclid&oq=site%3A&gs_l=serp.3.0.35i39l2j0i67l4j0i10j0i67j0j0i131.58677.61871.0.63823.11.8.3.0.0.0.208.930.0j3j2.5.0....0...1c.1.64.serp..8.3.419.nUJod6dYZmI Therefore these new pages are now being indexed, causing duplicate content. Does anyone have any idea about what to do in this situation? Thanks, Stephen.

Membership/subscriber (/customer) only content and SEO best practice
Hello Mozzers, I was wondering whether there's any best practice guidance out there re: how to deal with membership/subscriber (existing customer) only content on a website, from an SEO perspective - what is best practice? A few SEOs have told me to make some of the content visible to Google, for SEO purposes, yet I'm really not sure whether this is acceptable / manipulative, and I don't want to upset Google (or users for that matter!) Thanks in advance, Luke

Pagination duplicate title and meta description
Hello, Getting a lot of duplicate title and meta description errors via google webmaster tools. For best SEO practices, do i no-index the page/2's, page/3's...? More importantly, i see how MOZ did it by adding "page 3" to their titles such as http://moz.com/blog?page=3. Is that a better way of doing it? If so, how do i do that on Yoast SEO? Thank you so much!

Lowercase VS. Uppercase Canonical tags?
Hi MOZ, I was hoping that someone could help shed some light on an issue I'm having with URL structure and the canonical tag. The company I work for is a distributor of electrical products and our E-commerce site is structured so that our URL's (specifically, our product detail page URL's) include a portion (the part #) that is all uppercase (e.g: buy/OEL-Worldwide-Industries/AFW-PG-10-10). The issue is that we have just recently included a canonical tag in all of our product detail pages and the programmer that worked on this project has every canonical tag in lowercase instead of uppercase. Now, in GWT, I'm seeing over 20,000-25,000 "duplicate title tags" or "duplicate descriptions". Is this an issue? Could this issue be resolved by simply changing the canonical tag to reflect the uppercase URL's? I'm not too well versed in canonical tags and would love a little insight. Thanks!

Does Google bot read embedded content?
Is embedded content "really" on my page? There are many addons nowadays that are used by embedded code and they bring the texts after the page is loaded. For example - embedded surveys. Are these read by the Google bot or do they in fact act like iframes and are not physically on my page? Thanks

Duplicate Content on Press Release?
Hi, We recently held a charity night in store. And had a few local celebs turn up etc... We created a press release to send out to various media outlets, within the press release were hyperlinks to our site and links on certain keywords to specific brands on our site. My question is, should we be sending a different press release to each outlet to stop the duplicate content thing, or is sending the same release out to everyone ok? We will be sending approx 20 of these out, some going online and some not. So far had one local paper website, a massive football website and a local magazine site. All pretty much same content and a few pics. Any help, hints or tips on how to go about this if I am going to be sending out to a load of other sites/blogs? Cheers

Duplicate Content | eBay
My client is generating templates for his eBay template based on content he has on his eCommerce platform. I'm 100% sure this will cause duplicate content issues. My question is this.. and I'm not sure where eBay policy stands with this but adding the canonical tag to the template.. will this work if it's coming from a different page i.e. eBay? Update: I'm not finding any information regarding this on the eBay policy's: http://ocs.ebay.com/ws/eBayISAPI.dll?CustomerSupport&action=0&searchstring=canonical So it does look like I can have rel="canonical" tag in custom eBay templates but I'm concern this can be considered: "cheating" since rel="canonical is actually a 301 but as this says: http://googlewebmastercentral.blogspot.com/2009/12/handling-legitimate-cross-domain.html it's legitimately duplicate content. The question is now: should I add it or not? UPDATE seems eBay templates are embedded in a iframe but the snap shot on google actually shows the template. This makes me wonder how they are handling iframes now. looking at http://www.webmaster-toolkit.com/search-engine-simulator.shtml does shows the content inside the iframe. Interesting. Anyone else have feedback?

Are duplicate links on same page alright?
If I have a homepage with category links, is it alright for those category links to appear in the footer as well, or should you never have duplicate links on one page? Can you please give a reason why as well? Thanks!
