Is having "rel=canonical" on the same page it is pointing to going to hurt search?
-
i like the rel=canonical tag and i've seen matt cutts posts on google about this tag. for the site i'm working on, it's a great workaround because we often have two identical or nearly identical versions of pages: 1 for patients, 1 for doctors.
the problem is this: the way our content management system is set up, certain pages are linked up in a number of places and when we publish, two different versions of the page are created, but same content. because they are both being made from the same content templates, if i put in the rel=canonical tag, both pages get it. so, if i have:
http://www.myhospital.com/patient-condition.asp and http://www.myhospital.com/professional-condition.asp and they are both produced from the same template, and have the same content, and i'm trying to point search at http://www.myhospital.com/patient-condition.asp, but that tag appears on both pages
similarly, we have various forms and we like to know where people are coming from on the site to use those forms. to the bots, it looks like there's 600 versions of particular pages, so again, rel=canonical is great. however, because it's actually all the same page, just a link with a variable tacked on (http://www.myhospital.com/makeanappointment.asp?id=211) the rel=canonical tag will appear on "all" of them.
any insight is most appreciated!
thanks! brett

Got it. Dr.Pete have done excellent work on similar blog post. Right?

So, Does it really matter to add rel=canonical tag in each pages? Can I remove from web page?
It does matter, and you should not remove the canonical tag.
One example on the page you referenced is the following URL: http://www.vistapatioumbrellas.com/umbrella-stands?dir=asc&order=name
On the page you referenced visitors can change the default ORDER BY Position to ORDER BY Name (as an example) which changes the URL. Both pages are the same content but displayed different, which is exactly the type of issue canonicalization is designed to correct.

I am not getting clear idea by this answer. I am searching solution which may help me to solve same question.
I would like to share my URL.
http://www.vistapatioumbrellas.com/umbrella-stands
This page have rel=canonical tag for same page as follow.
<link rel="canonical" href="[http://www.vistapatioumbrellas.com/umbrella-stands](view-source:http://www.vistapatioumbrellas.com/umbrella-stands)" />
Website does not contain any duplicate page which is associated to this page. So, Does it really matter to add rel=canonical tag in each pages? Can I remove from web page?

Hi Brett.
Steven is correct. I think it will be helpful if I offer a bit more clarification.
www.myhospital.com/patient-condition.asp
www.myhopsital.com/professional-condition.asp
www.myhospital.com/patient-condition.asp?id=1
Those three URLs may point to the exact same page or very similar pages. Google simply wont index all 3 pages as it does not offer any user benefit. The best thing to do is tell Google which of these 3 pages is the primary page you wish listed. By placing the same canonical tag on all 3 pages, you are indicating to Google which page you wish listed.
With the above tag placed in all 3 pages, then Google knows in the first URL example they are dealing with the original page, and in the next 2 examples they are dealing with a copy.
NOTE: I am unsure why two users disliked this reply. It is correct. If I were to stretch, I can add that Bing stated their preference the canonical tag not used on a page who's URL matches the canonical, but they seem to handle it well with no issues.

With rel='canonical' you want to point all existing pages that have the same content to 1 page. Having a rel='canonical' on the page with itself as the href will not hurt, can only help verify that it is the preferred page.

Are "appliance repair" and "appliance repair los angeles" consider the same keyword?
Hello, I know that you can't optimize two pages for 1 keyword because Google will get confused and will rather prefer my competitor. But I can't get if it will consider "appliance repair" and "appliance repair los angeles" same keywords? The homepage of my website, https://www.ifixappliancesla.com, is optimized for "appliance repair", one of the inner pages is optimized for "appliance repair los angeles". None of them shows on the first page in local SERPs for any of those quires. I am wondering if this is because Google sees it as both pages are optimized for "appliance repair"?

My sites "pages indexed by Google" have gone up more than qten-fold.
Prior to doing a little work cleaning up broken links and keyword stuffing Google only indexed 23/333 pages. I realize it may not be because of the work but now we have around 300/333. My question is is this a big deal? cheers,

Can Title Tag be seen in the page source, but not seen by search engines?
This is a follow up question derived from a previous question I posted - http://moz.com/community/q/does-title-tag-location-in-a-page-s-source-code-matter There have been several reputable crawl tools used on our (including Moz) site that state we are missing title tags on may pages. One such page is http://www.paintball-online.com/Paintball-Guns-And-Markers-0Y.aspx I can see the title tag on line 238 of the page source. I find it unlikely that there is an issue with the crawl tools. Any thoughts would be greatly appreciated. Nick

Can I use high ranking sites to push my competitors out of the first page of search results?
I'm looking at a bunch of long tail low traffic keywords that aren't difficult to rank for. As I was idly doing a boring task my mind wandered and I thought.... Why don't I ask lots of questions about these keywords on sites such as Moz, Quora, Reddit etc where the high DA will get them to rank for the search term? The results on a SEO site or Q&A site won't be relevant and so I'd starve my competitors of some of their leads. Of course I'm not sure the effort would be worth it but would it work? (and no, none of my long tail keywords are included in this post)

Switchboard Tags - Multiple desktop pages pointing to one mobile page
I have recently started to implement switchboard tags to connect our mobile and desktop pages, and to ensure that our mobile pages show up in rankings for mobile users. Because our desktop site is much deeper in content than our mobile site, there are a number of desktop pages we would like to have point to one mobile page. However, with the switchboard tags, this poses a problem because it requires multiple rel=canonical tags to be placed on the one mobile page. I'm assuming this will either confuse the search engines, or they will choose to ignore the rel=canonical tag altogether. Any ideas on how to approach this situation other than creating an equivalent mobile version of every desktop page or implementing a user agent detection redirect?

Should component pages be visible in the search result?
Hi everyone, My question is suppose i have a blog having 200 pages arranged in footer like seomoz blog and when i move to 2nd page and say the url is http://www.seomoz.org/blog?page=2 and when i search exact url on google should this page be visible in search result or not. Since all component pages of seomoz blog are visible, i think this should not be a problem but when i see other popular blogs like SEJ and seroundtable none of their component pages are visible in search result. By the way i am using rel=prev and next but not robots: noindex, follow

At what point is the canonical tag crawled
Do search engines (specifically Google) crawl the url in the canonical tag as it loads or do they load the whole page before crawling it? Thanks,
