Adding Rel Canonical to multiple pages
-
Hi,
Our CMS generates a lot of duplicate content, (Different versions of every page for 3 different font sizes). There are many other reasons why we should drop this current CMS and go with something else, and we are in the process of doing that. But for now, does anyone know how would I do the following:
I've created a spreadsheet that contains the following:
Column 1: rel="canonical" tag for URL
Column 2: Duplicate Content URL # 1
Column 3: Duplicate Content URL # 2
Column 4: Duplicate Content URL # 3
I want to add the tag from column 1 into the head of every page from column 2,3, and 4.
What would be a fast way to do this considering that I have around 1800 rows.
Check the screenshot of the builtwith.com result to see more information about the website if that helps.

Yeah, wish I could give you a simpler answer, but I'm afraid it might end up being a little tricky. Hit the biggest problems first, and at least you can manage time/money a bit. The one bright side is that the rules should be no harder to code in ColdFusion than anything else (PHP, ASP, whatever). It's just the core logic that's tricky.
-
That's what I thought. I need to find someone in the company who knows cold fusion and go through it.
Thanks for your help though. I appreciate it.

Unfortunately, the rules may differ from page to page and will be entirely dependent on how your pages are generated. If it's just a matter of the "index.cfm" version vs. root ("/") versions of pages, those canonical should be straightforward. For the other parameters, though (like "i", "fs", etc.), it depends entirely on the function of those parameters.
I know ColdFusion reasonably well, and even given that, I couldn't give you a one-size-fits-all rule that would solve the problem. It really has to be guided by your site structure and code/data logic. Personally, I'd start with the pattern that generates the most problems and solve that one first. In other words, if one template (like "/press-releases") generates dozens or hundreds of duplicates, deal with that first. If you solve the top 3-4 problems, you may clean up quite a bit. That could be more effective than trying to fix everything at once.

Here's a spreadsheet sample. I did what Roberto suggested. I have a column with the ready for every duplicate content URL.
The site is dynamic. That was the main problem I was facing, I'm not sure how to set the canonicals on each page without having to go into the html and copy the tag from the spreadsheet to the manually.
I added the screenshot of builtwith.com in the main question hoping it would give anyone insight as to how I would code rules to set the canonicals.
-
Could you provide an approximate example that matches your real situation (a fake domain is fine, but with the same basic format)? This is a situation where fake examples that don't match the real situation probably won't help us (or you) much.
Once you have the spreadsheet, how are you going to translate that into tags? If this is a dynamic site, it would be better to be able to code rules to set the canonicals - and potentially much easier.
-
Following the same concept:
- Create a column (Column E) with the following information "then another column (Column F) with ""/>"
- In column G enter the following formula: =CONCATENATE(E1,Cell of Duplicate URL, F3).
The end result will have Column A with the Domain in it. Follow steps 6 & 7 to complete the process.
Feel free to send me a sample spreadsheet with some info and I can set it up for you.

Roberto, Thank you for your answer. I just realized that I was unclear when I asked the question. I already have the link containing the canonical tag for each of the URLs ready. That is what column A already contains. I need to add that into the section of the pages in column 2,3, and 4. I'm just unsure how to do this for 1800 rows each containing the correct URL in column A, and in column 2,3, and 4 the URLs of the duplicate content pages that need the link added to the section. Check the image below to see what I mean. I appreciate the effort though Farris

Farris,
This is the way I would do it.
You have the following columns created:
- Column A: "canonical" tag for UR
- Column B: Duplicate Content URL # 1
- Column
Duplicate Content URL # 2
- Column
Duplicate Content URL # 1
Follow the next steps:
- Create three more columns with to duplicate columns B, C, D
- Use the following formula on column B "**=CONCATENATE(A1,B1)" **
- Copy the same formula for columns C & D
- Replace the “B1” in your formula for the respective columns (i.e. Column C should have C1.)
- Copy & Paste the content of columns E, F, G (The copied columns with formulas) to all the rows.
- Once copied, the information in columns E, F, G should look like the end result that you want.
- if data is correct, copy columns E, F, G and paste in the same location but use Paste Special and paste values only. This will remove your formulas.
I hope this helps.

Removing a canonical tag from Pagination pages
Hello, Currently on our site we have the rel=prev/next markup for pagination along with a self pointing canonical via the Yoast Plugin. However, on page 2 of our paginated series, (there's only 2 pages currently), the canonical points to page one, rather than page 2. My understanding is that if you use a canonical on paginated pages it should point to a viewall page as opposed to page one. I also believe that you don't need to use both a canonical and the rel=prev/next markup, one or the other will do. As we use the markup I wanted to get rid of the canonical, would this be correct? For those who use the Yoast Plugin have you managed to get that to work? Thanks!

Rel=canonical on Godaddy Website builder
Hey crew! First off this is a last resort asking this question here. Godaddy has not been able to help so I need my Moz Fam on this one. So common problem My crawl report is showing I have duplicate home pages www.answer2cancer.org and www.answer2cancer.org/home.html I understand this is a common issue with apache webservers which is why the wonderful rel=canonical tag was created! I don't want to go through the hassle of a 301 redirect of course for such a simple issue. Now here's the issue. Godaddy website builder does not make any sense to me. In wordpress I could just go add the tag to the head in the back end. But no such thing exist in godaddy. You have to do this weird drag and drop html block and drag it somewhere on the site and plug in the code. I think putting before the code instead of just putting it in there. So I did that but when I publish and inspect in chrome I cannot see the tag in the head! This is confusing I know. the guy at godaddy didn't stand a chance lol. Anyway much love for any replies!

Are image pages considered 'thin' content pages?
I am currently doing a site audit. The total number of pages on the website are around 400... 187 of them are image pages and coming up as 'zero' word count in Screaming Frog report. I needed to know if they will be considered 'thin' content by search engines? Should I include them as an issue? An answer would be most appreciated.

Rel canonical between mirrored domains
Hi all & happy new near! I'm new to SEO and could do with a spot of advice: I have a site that has several domains that mirror it (not good, I know...) So www.site.com, www.site.edu.sg, www.othersite.com all serve up the same content. I was planning to use rel="canonical" to avoid the duplication but I have a concern: Currently several of these mirrors rank - one, the .com ranks #1 on local google search for some useful keywords. the .edu.sg also shows up as #9 for a dirrerent page. In some cases I have multiple mirrors showing up on a specific serp. I would LIKE to rel canonical everything to the local edu.sg domain since this is most representative of the fact that the site is for a school in Singapore but...
Technical SEO | | AlexSG
-The .com is listed in DMOZ (this used to be important) and none of the volunteers there ever respoded to requests to update it to the .edu.sg
-The .com ranks higher than the com.sg page for non-local search so I am guessing google has some kind of algorithm to mark down obviosly local domains in other geographic locations Any opinions on this? Should I rel canonical the .com to the .edu.sg or vice versa? I appreciate any advice or opinion before I pull the trigger and end up shooting myself in the foot! Best regards from Singapore!0 -

Multiple urls for posting multiple classified ads
Want to optimize referral traffic while at same time keep search engines happy and the ads posted. Have a client who advertises on several classified ad sites around the globe. Which is better (post Panda), having multiple identical urls using canonicals to redirect juice to original url? For example: www.bluewidgets.com is the original www.bluewidgetsusa.com www.blue-widgets-galore.com Or, should the duplicate pages be directed to original using a 301? Currently using duplicate urls. Am currently not using "nofollow" tags on those pages.

Home Page .index.htm and .com Duplicate Page Content/Title
I have been whittling away at the duplicate content on my clients' sites, thanks to SEOmoz's pro report, and have been getting push back from the account manager at register.com (the site was built here and the owner doesn't want to move it). He says these are the exact same page and he can't access one to redirect to the other. Any suggestions? The SEOmoz report says there is duplicate content on both these urls: Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/index.htm Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/ Your help is greatly appreciated!
