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!

Move to new domain using Canonical Tag
At the moment, I am moving from olddomain.com (niche site) to the newdomain.com (multi-niche site). Due to some reasons, I do not want to use 301 right now and planning to use the canonical pointing to the new domain instead. Would Google rank the new site instead of the old site? From what I have learnt, the canonical tag lets Google know that which is the main source of the contents. Thank you very much!

Htaccess - Redirecting TAG or Category pages
Hello Fellow Moz's, We have an issue redirecting some /TAG and /Category pages to inner pages. As an example we use: RedirectMatch 301 /category/Sample-Category(.*) https://OurDomain.com.au/New-Page//$1 That works well. The issue is we have other categories and tags that are named similar to /Sample-Category As an example, if we try to redirect /Sample-Category-1 to /New-Page-1 - it will not work, and redirects to /New-Page I assume this is because /Sample-Category is already being redirected, so anything after /Sample-Category like -1 or -2 or -3 etc, will not be recognized. Anyone know of a workaround?

Bad SEO Practice: in title tag?
Greetings, I just discovered that some of our content was produced with

tags in the title tag. Example: <title>Diabetes Symptoms <br> In Women Over 40</title> My gut says this is bad for SEO, but I couldn't find a definitive answer on the web, so I thought I would ask the community of gurus here at Moz. 🙂 Thanks in advance for any reply. Kind regards, Eric0 -
Fast/Easy Way to Implement Canonical tags in Bulk in Magento CMS?
Hello Amazing SEO Community! Quick Q for a client with a TON of duplicate content. (yikes!) My client is currently undertaking a large SEO project around canonical tagging for their thousands of duplicate pages. Currently, one product sits on multiple URLs and they are being indexed as different pages (with the same content). The issue is found across all products and other pages, and across their international sites as well. One core challenge they face now is lack of time/resources from their developer side. The solution we see to the duplicate content is to manually add a canonical tag to each of our tens of thousands of pages. Their content management system is Magento. Has anyone ever tackled canonicalization for a large site that uses Magento? Any more efficient solutions to manual tagging is ideal. Thanks in advance for your input. -Bonnie

Proper Title Tags for ecommerce
In terms of E-commerce title tags. We are a manufacturer of our own clothing products. We are new to the SEO landscape so if this question is an obvious answer, then i apologize for wasting any one times in advance. We Manufacture our own clothing. Each item has a name. The names are American womens names such as amanda or lori or jenniffer etc. When we create the title tag for them should we include the name of the item itself at the beginning or end. For example should it be Item Name - Keyword - Keyword - Brand Name(aka manufacturer) or Keyword - Keyword - Item Name - Brand Name (aka manufacturer) The reason we ask this is because we think it would be a waste to rank for actual American names such as Jennifer and Jessica. All that we have read on Moz suggests that it seems to be better to have pertinent keywords in the beginning of the title as opposed to the end. In terms of our brand name we already rank number 1 for every combination of our brand. So we would like to start picking up traffic for the different product types we sell and there respective synonyms. Not sure if i am making any sense. Sorry in advance, and any help is very very much appreciated.

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.
Intermediate & Advanced SEO | | kinimod
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 -

External 404 vs Internal 404
Which one is bad? External - when someone adds an incorrect link to your site, maybe does a typo when linking to an inner page. This page never existed on your site, google shows this as a 404 in Webmaster tools. Internal - a page existed, google indexed it, and you deleted it and didnt add a 301. Internal ones are in the webmaster's control, and i can understand if google gets upset if it sees a 404 for a URL that existed before, however surely "externally created" 404 shoudnt cause any harm cause that page never existed. And someone has inserted an incorrect link to your site.
