I still don't understand how rel=canonical works. Help?
-
So here's the deal. I write for many different outlets. I also have many different pages on my blog that have duplicates (authorized, of course). On my blog, I have many different pages that redirect to "the original" content.
I've only recently discovered the existence of rel=canonical. However I don't understand how it works. I have very specific questions. Can anyone help?
-
If, on my blog, I have a blog post that's the original. And another website has the same content, used with authorization. If I want to tell search engines that the original content is on MY blog, what can I do? Is the only solution to ask the owner of the other blog to add a rel=canonical in the header of the specific post?
-
If, on my blog, I have a blog post that's NOT the original. Do I simply add rel=canonical to the header, then add a link to the original in the body?
-
If, on my blog, I have THE FIRST 300 WORDS of a blog post, then add a link saying "to read the whole article, click here" with a link pointing to the original, do I need to have a rel=canonical tag somewhere? Does it HAVE to be in the header?

Hi Cedriklizotte,
No, there is no need to put the second link Click here in the body. Only the first link would be enough to put in the section.

Thank you very much for your detailed answer.
One last question: do I need to put BOTH in the header and Click here in the body? Or am I confused again?
Thanks again

Hi Cedriklizotte,
As per your queries, you have recently discovered about the rel="canonical" tag so let's try to understand this first. As you have mentioned that some of the pages redirect to the "original content". So its better to put the rel="canonical" tag to the original link because that'll be the preferred URL when it comes to tell the search engines about which page to consider as the "original content". So this code would look like:
And put this code in the section of the page.
Now, let's try to answer your questions one by one:
Question: If, on my blog, I have a blog post that's the original. And another website has the same content, used with authorization. If I want to tell search engines that the original content is on MY blog, what can I do? Is the only solution to ask the owner of the other blog to add a rel=canonical in the header of the specific post?
Answer: In this scenario, as you suggested its better to ask the owner of the other blog to add a rel=canonical with the link to your blog in the section of the specific post.
Question: If, on my blog, I have a blog post that's NOT the original. Do I simply add rel=canonical to the header, then add a link to the original in the body?
Answer: You should mark up the page with the rel=canonical tag in the section in the format that I have mentioned.
If the body has a CTA (Call To Action) button that takes to the original post then put the link there and no need to put rel=canonical tag there because you have already put the rel=canonical tag in that page with the preferred URL or original link.
Question: If, on my blog, I have THE FIRST 300 WORDS of a blog post, then add a link saying "to read the whole article, click here" with a link pointing to the original, do I need to have a rel=canonical tag somewhere? Does it HAVE to be in the header?
Answer: Yes, better to put the rel=canonical in the header.
Question: Can rel=canonical be used in the
_[Answer: Yes, rel=canonical is always used in the <href=>element format of a link in order to tell search engines that the original of content is actually on the other blog.</href=>
Question: What penalties are included with having duplicate content of my work everywhere on the web? I've been trying to find specifics, but can't.
Answer: Just check this link: https://webmasters.googleblog.com/2008/09/demystifying-duplicate-content-penalty.html from Google Webmasters blog about the duplicate content penalties and you'll get a fair idea about the specifics.
I hope this would help.

Hiding body copy with a 'read more' drop down option
Hi I just want to confirm how potentially damaging using java script to hide lots of on page body copy with a 'read more' button is ? As per other moz Q&A threads i was told that best not to use Javascript to do this & instead "if you accomplish this with CSS and collapsible/expandable <DIV> tags it's totally fine" so thats what i advised my clients dev. However i recently noticed a big drop in rankings aprox 1 weeks after dev changing the body copy format (hiding alot of it behind a 'read more' button) so i asked them to confirm how they did implement it and they said: "done in javascript but on page load the text is defaulting to show" (which is contrary to my instructions) So how likely is it that this is causing problems ? since coincides with ranking drop OR if text is defaulting to show it should be ok/not cause probs ? And should i request that they redo as originally instructed (css & collapsible divs) asap ? All Best Dan

Why don't all my pages have On Page Optimization Reports
Apologies if this question has been asked a million times, but I can't find it. I have 35 pages, yet only 5 of them have generated On Page Optimization Reports. I know I can create them manually, but wondered if I've done something incorrectly? Iain.

Does adding ™ help or hurt?
I have a client who rents kids' party products that are branded (Batman, Curious George, etc.) Does it help or hurt to put the superscript "TM" in the Meta Title, or other meta or actual content of their product listings? I have some guesses, but am curious for other opinions / data! Thanks very much!

Rel canonical tag question
Im trying to to fix my duplicate content problem with my catagory pages in my shopping cart. I have read about adding a rel canonical tag to the page so it links back to the main catagory page. So if I add a rel canonical tag to the main catagory page it will show up on every other page for that catagory like page 1 page 2 and so on and it will have the tag linking back to the main cat. That should fix it it right? Now that being said I cant seem to add the tag invetween the head tags. I can add it to the body where I can add content. Will the rel canonical tag work outside the head tags? Any other ideas on this fix? I contacted my people that host the cart to see if they have any features to help this will see what they say.

Help I don't understand Rel Canonical
I'm really stuck on how to fix up Rel Canonical errors on a Wordpress site. I went in and changed all the URLs to remove the www and added / to the end. I get this message on page analysis details: <dt>Canonical URL</dt> <dd>"http://www.some-url.com.au/",</dd> <dd>"http://some-url..com.au/", and</dd> <dd>"http://some-url..com.au/"</dd> <dd>Well the first one with the www doesn't exists and the second two urls are the same! (Note that I have removed the actual URL for this post)</dd> <dd>I'm not sure how to read and fix the errors from the reports ether. The only issues I can see is that the 'Tag Value' has the www and the 'Page Title - URL' doesn't have the www.

Canonical URL's - Fixed but still negatively impacted
I recently noticed that our canonical url's were not set up correctly. The incorrect setup predates me but it could have been in place for close to a year, maybe a bit more. Each of the url's had a "sortby" parameter on all of them. I had our platform provider make the fix and now everything is as it should be. I do see issues caused by this in Google Webmaster, for instance in the HTML suggestions it's telling me that pages have duplicate title tags when in fact this is the same page but with a variety of url parameters at the end of the url. To me this just highlights that there is a problem and we are being negatively impacted by the previous implementation. My question is has anyone been in this situation? Is there any way to flush this out or push Google to relook at this? Or is this a sit and be patient situation. I'm also slightly curious if Google will at some point look and see that the canonical urls were changed and then throw up a red flag even though they are finally the way they should be. Any feedback is appreciated. Thanks,
