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!

Thanks for the feedback, Federico! That actually helps a lot and also helps confirm what our programmer has just done (which is changed all the canonical tags to the uppercase URL). I guess now we'll play the waiting game and see if Google reduces the number or duplicates after it's next crawl.
Thanks again!

That should be an easy fix for your programmer. If your internal links point to pages with uppercase letters in them, then have the canonical tags with the uppercase. Almost always, uppercase and lowercase loads the same content as the rewrite rules use the URL to look on the products using a DB that does not distinguish uppercase & lowercase automatically (in MySQL, you can force the query to do so, but that will be actually more difficult to just change the way the programmed made the canonical tags). You should also redirect the pages that are duplicate to the original ones, if they have uppercase letters (the original) then the lowercase version should redirect to the uppercase one (once the canonical tags are properly set).
From MY OWN PERSONAL point of view, I always preferred lowercase URLs... if that's the case there's a little more coding to do, but you will end up with all URLs in lowercase (for some reason almost all CMS automatically convert uppercase letters to lowercase in a page URL, like Wordpress does).
Hope that helps!

Near Duplicate Title Tag Checker
Hi Everyone, I know there are a lot of tools like Siteliner, which can check the uniqueness of body copy, but are there any that can restrict the check to the title tags alone? Alternatively, is there an Excel or Google Sheets function that would allow me to do the same thing? Thanks, Andy

Why is our noindex tag not working?
Hi, I have the following page where we've implemented a no index tag. But when we run this page in screaming frog or this tool here to verify the noidex is present and functioning, it shows that it's not. But if you view the source of the page, the code is present in the head tag. And unfortunately we've seen instances where Google is indexing pages we've noindexed. Any thoughts on the example above or why this is happening in Google? Eddy

Absolute vs. Relative Canonical Links
Hi Moz Community, I have a client using relative links for their canonicals (vs. absolute) Google appears to be following this just fine, but bing, etc. are still sending organic traffic to the non-canonical links. It's a drupal setup. Anyone have advice? Should I recommend that all canonical links be absolute? They are strapped for resources, so this would be a PITA if it won't make a difference. Thanks

Top hierarchy pages vs footer links vs header links
Hi All, We want to change some of the linking structure on our website. I think we are repeating some non-important pages at footer menu. So I want to move them as second hierarchy level pages and bring some important pages at footer menu. But I have confusion which pages will get more influence: Top menu or bottom menu or normal pages? What is the best place to link non-important pages; so the link juice will not get diluted by passing through these. And what is the right place for "keyword-pages" which must influence our rankings for such keywords? Again one thing to notice here is we cannot highlight pages which are created in keyword perspective in top menu. Thanks

Pagination parameters and canonical
Hello, We have a site that manages pagination through parameters in urls, this way: friendly-url.html
Intermediate & Advanced SEO | | teconsite
friendly-url.html?p=2
friendly-url.html?p=3
... We've rencently added the canonical tag pointing to friendly-url.html for all paginated results. In search console, we have the "p" parameter identified by google.
Now that the canonical has been added, should we still configure the parameter in search console, and tell google that it is being use for pagination? Thank you!0 -
Microsites: Subdomain vs own domains
I am working on a travel site about a specific region, which includes information about lots of different topics, such as weddings, surfing etc. I was wondering whether its a good idea to register domains for each topic since it would enable me to build backlinks. I would basically keep the design more or less the same and implement a nofollow navigation bar to each microsite. e.g.

weddingsbarcelona.com
surfingbarcelona.com or should I rather go with one domain and subfolders: barcelona.com/weddings
barcelona.com/surfing I guess the second option is how I would usually do it but I just wanted to see what are the pros/cons of both options. Many thanks!0 -
Meta tags - are they case sensitive?
I just ran the wordtracker tool and noticed something interesting. The tool didn't pick up our meta description. It's strange as our meta descriptions appear in organic search results and Moz never reported missing meta descriptions.After reviewing other pages, I noticed our meta description tag is written as the following: name="Description" content=" I never thought about this, but are meta tags case sensitive? Should it be written as: name="description" content=" Thoughts?

Any penalty for having rel=canonical tags on every page?
For some reason every webpage of our website (www.nathosp.com) has a rel=canonical tag. I'm not sure why the previous SEO manager did this, but we don't have any duplicate content that would require a canonical tag. Should I remove these tags? And if so, what's the advantage - or disadvantage of leaving them in place? Thank you in advance for your help. -Josh Fulfer
