How long to reverse the benefits/problems of a rel=canonical
-
If this wasn't so serious an issue it would be funny....
Long store cut short, a client had a penalty on their website so they decided to stop using the .com and use the .co.uk instead. They got the .com removed from Google using webmaster tools (it had to be as it was ranking for a trade mark they didn't own and there are legal arguments about it)
They launched a brand new website and placed it on both domains with all seo being done on the .co.uk. The web developer was then meant to put the rel=canonical on the .com pointing to the .co.uk (maybe not needed at all thinking about it, if they had deindexed the site anyway). However he managed to rel=canonical from the good .co.,uk to the ,com domain!
Maybe I should have noticed it earlier but you shouldn't have to double check others' work! I noticed it today after a good 6 weeks or so. We are having a nightmare to rank the .co.uk for terms which should be pretty easy to rank for given it's a decent domain.
Would people say that the rel=canonical back to the .com has harmed the co.uk and is harming with while the tag remains in place? I'm off the opinion that it's basically telling google that the co.uk domain is a copy of the .com so go rank that instead.
If so, how quickly after removing this tag would people expect any issues caused by it's placement to vanish?
Thanks for any views on this. I've now the fun job of double checking all the coding done by that web developer on other sites!

Yeah, if the .com is blocked now, there's really no point in putting 301s or canonicals over there, because they won't do anything (theoretically, at least). You could put self-referencing canonicals on the .co.uk site. It would at least be a nudge to Google to ignore the old canonicals (to the .com). Other than that, you may have to wait and see.
As Alan said, you could 301-redirect the .com and then stop blocking it. Properly redirected, no visitors should be able to view the old pages. In some ways, that's even more reliable than blocking.
Update: Sorry, realized that was a bit confusing, as I sort of told you that a 301 was pointless but then to 301 What I'm saying is that you could stop blocking the .com and THEN 301-redirect it. If it really is fully blocked, 301-ing it probably won't have any impact (although it won't hurt anything).

If the .com is de indexed, then i would either get rid of it, or 301 it to the .uk

Dr Pete,
The whole thing has been one issue after another with the client. One of those helpful clients whom change their website and page structure without telling you. First you hear about it is when they call you wanting to know why their rankings have dropped!
The idea was to move away from the .com site and use the .co.uk site, however they had a lot of people visiting the .com and wanted to keep that as a live site. What should have been done (what I advised them on) was to canonical from the .com to the uk site, telling google that the uk domain is now the main domain. Helpful and rather impressively their web developer managed to put the canonical tag on the .co.uk domain telling google the .com was the main domain.
Then, the .com got involved in a trademark dispute so they decided to remove it from the google listings via webmaster tools (it is still removed as it still ranks for the trademark keyword when it's unblocked). The long and short of it was they ended up in a position which the site they wanted to be ranking was being ignored by google in favour of the site they blocked from google!
I guess now it's a question of just waiting for google to recrawl the .co.uk and see the tag has gone. It's a basic seo error on my part but I would have trusted an experienced web designer to copy and paste a code I gave him on to the correct site.
Don't you just love the clients which won't give you ftp access and insist all changes go through their web developer who is freelance!!
Thanks for the help on this everyone

I'm thinking the same thing - if possible, the 301 might help override the canonical. Sometimes, in my experience, if you reverse a signal (like rel-canonical) with that same signal, Google takes it's time to re-evaluate, because the reversal just looks odd. The 301 here might be more insistent.
The link profile and other signals should help, but I've seen reversing a bad canonical take weeks. It's a tough signal to undo.
Is the .com site still blocked, though? If you canonical'ed to a blocked site and now are trying to reverse it, but the site is still blocked, Google won't crawl the new signal (the same would be true for 301s). If the .com is blocked somehow and you remove the bad canonical, Google may act more quickly (since canonicalizing to a blocked site would seem strange).

I would not do anything, it will sort out soon enouth. I dont think it will happen first crawl, as i remeber google saying that they dont honer redirects first time as you may be making changes when crawled, so it may a take a few crawls, also it is not clear if you get all link juice back when it is crawled or when the pages that link to you are crawled. to explain further, if i had a link pointing to you, would the link juice point back to your .uk when your page gets crawled, or when i get crawled?
My guess you will start seeing value return over a period, from day one (as most sites get a few pages a day crawled) up untill a couple of months.

Would a 301 from .com to .co.uk work better?
-
the dreaded call to the client, I dont envy you, but be open and honest and all will work out for the best.
Aas SEOs were supposed to notice the finer details, but were only human.
In the past I've put these 'issues' down to 'communication problems with the clients outsourced develeopers', perhaps they should cosider moving development to you guys

Thanks for the reply.
Hopefully the large number of backlinks to it will mean it gets recrawled very quickly. I had spent weeks trying to work out why I could get the .co.uk homepage indexed in google now I know why. Now comes a nice call to the client, eek! Thankfully the web design works freelance and is employed by the client not me

Hi MisterG,
I feel your pain and learnt the same lesson a few years back. Now i double check everything our devs do.
I agree with you that the canonical is tell Google to go rank the .com as its the authorative owner of the co.uk's content.
How log its going to take to remedy after sortig out the canonical is anyones guess. I suppose it depends on how often you get crawled (deeply).
Be patient and cross your fingers! (oh and dont be too harsh on the devs, they are simple logical creatures!)

Should we change our URLs for SEO benefit?
Hi, I'm currently covering a maternity marketing role at i-escape and one our main objectives is to increase organic traffic to the website. i-escape has a selection of hand-picked boutique hotels, villas, lodges, guesthouses and apartments for people to discover and book. At the moment each hotel page URL follows this structure: https://www.i-escape.com/hotelname We'd like to change this to include some searchable words in the URL dependent on the type of hotel. For example: https://www.i-escape.com/boutique-hotels/hotelname or https://www.i-escape.com/boutique-apartments/hotelname If we do go ahead, we know we need to make sure all old style URLs canonically redirect to the new style. Is having the keyword in the URL important enough for us to change over 1500 URLs on the website? We have quite a high quality links pointing to these hotel pages URLs. Also, will this help us with navigation/user journeys/crawls as there will be a /boutique-hotels/hotelname rather than just /hotelname? Thanks so much all! Clair

Http:// to https:// 301 or 302 redirect
I've read over the Q & A in the Community, but am wondering the reasoning behind this issue. I know - 301's are permanent and pass links, and 302s are temporary (due to cache) and don't pass links. But, I've run across two sites now that 302 redirect http:// to https://. Is there a valid reason behind this? From my POV and research, the redirect should 301 if it's permanent, but is there a larger issue I am missing?

How can I change the page title "two" (artigos/page/2.html) in each category ?
I have some categories and photo galleries that have more than one page (i.e.: http://www.buffetdomicilio.com/category/artigos and http://www.buffetdomicilio.com/category/artigos/page/2). I think that I must change the tittle and description, but I don't how. I would like to know how can I change the title of each of them without stay with duplicate title and description. Thank you! ahcAORR.jpg

Rebranding / Redirecting
Hi I have a client who wants to re-brand their shopify clothing store under new domain name. Whilst still a clothing store its going to have different department structure and product pages and will hence be a different store/site. Is there anyway to pass any of the history/authority of existing site to the new one such as 301 redirecting the top level pages of existing site to nearest equivalent pages of new site etc or best to just redirect the old site domain to the new ? Cheers Dan

Rel=canonical and Google analytics referrals
Hello guys, If I put (rel=can) from site1.com/page1 to site2.com/page1, will site2.com see in his Google Analytics that people are coming from site1.com in the referrals section or somewhere else? I can't find anything on the web about that. Thanks.

Benefits to having an HTML sitemap?
We are currently migrating our site to a new CMS and in part of this migration I'm getting push-back from my development team regarding the HTML sitemap. We have a very large news site with 10s of thousands of pages. We currently have an HTML sitemap that greatly helps with distributing PR to article pages, but is not geared towards the user. The dev team doesn't see the benefit to recreating the HTML sitemap despite my assurance that we don't want to lose all these internal links since removing 1000s of links could have a negative impact on our Domain Authority. Should I give in and concede the HTML sitemap since we have an XML one? Or am I right that we don't want to get rid of it?

Canonicals for Real Estate
A real estate site has a landing page for a particular zip code: site.com/zip/99999 On this page, there are links which add arguments to the URL, resulting in structures like this: site.com/zip/99999?maxprice=1000000&maxbeds=3 My question is on using a canonical URL for the pages with arguments. These pages may have lots of duplicate content, so should I direct search engines back to the base URL for the search? (site.com/zip/99999) A side note is that these pages with arguments could have no listings returned (no listings found) or could come back with listings (then it wouldn't be duplicate), but that can change on a day to day basis.

Canonical Issues
Hi Guys, I have a technical question. Ive started optimising an ecommerce site for a client and come across some duplicate content issues:- This page: http://www.bracknelllamps.com/projector-manufacturer/SANYO/70 is actually indexed in Google as:- http://www.bracknelllamps.com/projector-lamps.php?make=SANYO Both pages have the same content and I'm guessing the indexed page refers to an old way of navigating the site. As I'm concerned about duplicate content issues, what's the best approach as this seems to be the case for all 'projector manufacturer' pages. would it be to 301 redirect each manufacturer url (this could take forever with 107) manufacturers or rel="canonical" tag? to show Google which page I want indexing? Kind Regards Neil
