Canonical OR redirect
-
Hi,
i've a site about sport which cover matches. for each match i've a page.
last week there was a match between: T1 v T2
so a page was created:
www.domain.com/match/T1vT2 - Page1
this week T2 host T1, so there's a new page
www.domain.com/match/T2vT1 - Page2
each page has a unique content with Authorship, but the URL, Title, Description, H1
look very similar cause the only difference is T2 word before T1.
though Page2 is available for a few days, on site links & sitemap, for the search query "T2 T1 match" Page1 appears on the SERP (high location).
of course i want Page2 to be on SERP for the above query cause it's the relevant match.
i even don't see Page2 anywhere on the SERP and i think it wasn't indexed.
Questions:
1. do you think google see both pages as duplicated though the content is different?
2. is there a difference when you search for
T1 vs T2
OR
T2 vs T1
?
3. should i redirect 301 Page1 to Page2? consider that all content for Page1 and the Authorship G+ will be lost.
4. should i make rel=canonical on Page1 to Page2?
5. should i let google sort it out?
i know it's a long one, thanks for your patience.
Thanks,
Assaf

Thanks for everything.
i'll stick to the slower method and see what's going on in the index.

(2) It could take a while, yes. There is no speedy way to de-index a lot of content that is no longer crawlable, I'm afraid, unless it's currently in a directory that can be removed in Google Webmaster Tools.
(3) So, basically, let's say all the pages live under "/events" - you'd create "/events2", put all the new events in that going forward, and them remove "/events" in GWT?
It could work for removal, but changing your site architecture that way carries a significant amount of risk. You'll also have to make sure that you have a plan going forward for de-indexing new content that becomes outdated, because this is not something you want to do every couple of months. Honestly, unless you know the old content is harming your rankings, I probably wouldn't do this. I'd stick to the slower method.

Dear Dr. Meyers,
very insightful!!!
i must clear all the irrelevant page and the sooner the better.
(1) could take months or years
(2) sounds as a very good approach - i'm building my Sitemap with code so it's not a problem. the only problem is with a few hundreds at a time it could also take a long time. and wouldn't google spend a lot of time on crawling those pages and index less of the fresh new ones?
(3) what about google removal tool - and it's connected to my point on last post about setting a new site architecture:
- for all new matches=Pages create a new directory (without the irrelevant pages)
- ask WMT removal tool to remove the old directory and with it all the irrelevant pages (of course according to the guidelines for this tool)
what do you think about this approach?
Thanks again for all your help, i really appreciate it!
Assaf.

Oh, wow - yeah if only 2K are current and 120K are indexed, you definitely should be proactive about this. Unfortunately de-indexing content that's already been indexed is tough. Robots.txt isn't terribly effective after-the-fact, and the folder-based approach you've described won't work. You can move the pages and remove the folder (either with Robots.txt or in Webmaster Tools), but you haven't tied the old URLs to the new URLs. To remove them, first you have to tell Google they've moved.
First, pick your method. If these old events have any links/traffic/etc., then you may want to rel=canonical or 301-redirect. Otherwise, you could META NOINDEX or even 404. It depends a bit on their value. Then, a couple of options:
(1) You can wait and see. Let Google clear out the old events over time. If you're not at any risk, this may be fine. Monitor and see what happens.
(2) Encourage Google to re-crawl the old pages by creating a new, stand-alone sitemap. Then, monitor that sitemap in GWT for indexation. You don't have to do all 120K at once, but you could start with a few hundred (hopefully, you can build the XML with code, not by hand) and see how it progresses).

Dear Dr. Meyers,
i'm starting to understand i've a much bigger problem.
all finished matches are not relevant anymore and though you can reach them (their Page) from SERP or direct URL, they don't appear on site links OR sitemap. so the best idea is to remove all these old pages from google index - they don't contribute + they made my index status contain 120k pages while only 2000 are currently relevant.
this causes waste of google crawling on irrelevant pages and a potential that google may see some of them as dupes cause in some cases most of the page is relatively similar.
one suggestion i got is - after a match finishes pragmatically add to the page and google will remove it from it's index. - will it remove it if there're no links/sitemap to this page???
but i also have to handle the problem of the huge index - the above approach may/or not handle pages from now on, but what about all the other far past pages with finished matches??? how can i remove them all from the index.
-
adding <meta name="robots" content="noindex,follow">to all of them could take months or more to clean the index cause they're probably rarely crawled.</meta name="robots" content="noindex,follow">
-
more aggressive approach would be to change this site architecture and restrict by robot.txt the folder that holds all the past irrelevant pages.
so if today a match URL is like this: www.domain.com/sport/match/T1vT2
restrict www.domain.com/sport/match/ on robots.txt
and from now on create all new matches on different folder like: www.domain.com/sport/new-match/T1vT2
-
is this a good solution?
-
wouldn't google penalize me for removing a directory with 100k pages?
-
if it's a good approach, how much time it will take for google to clear all those pages from it's index?
I know it's a long one and i'll really appreciate your response.
Thanks a lot,
Assaf.

The problem with (2) is that, if you cut the crawl path, Google can't process any on-page directives, like 301s, canonicals, etc. Now, eventually, they might try to re-crawl from the index (knowing the URL used to exist), but that can take a long time. So, while canonical is probably appropriate here, you may have to leave the old event/URL active long enough for Google to process the tag.
If these are really isolated cases, I wouldn't worry too much. Maybe rel=canonical them, and eventually Google will flush out the old URL. If this starts happening a lot, I'd really consider some kind of permanent URL for certain match-ups and events.
There's no easy answer. This stuff is very site-specific and can be tricky.

i've got some good responses, but i'm not sure what to do.
any other opinions will be highly appreciated.
Thanks!

Hi Dr. Meyers,
thanks for your detailed response.
just wanted to refine my scenario:
1. the case of pairs (repeat match after a short term) is rare, but i encountered it.
2. there're no links or sitemap entry for the match that already finished. but google keeps it in the index. the page is reachable ONLY by direct URL address or from the SERP.
3. i don't think i can enforce google to automatically remove the old match from the index and doing it manually for 1000's of matches is not an option.
4. i thought google recognize the content of each page to determine if it's duplicate and not only by the URL/title - by tool the content is only 66% similar.
5. currently i've this problem twice - so for one case i've made rel=canonical and the other one i'm letting google to decide. when google encounters a rel=canonical does it goes to the URL of the canonical?
Thanks,
Assaf.

This is a pretty common problem with event-oriented sites, and there's no easy solution. It's a trade-off - if you keep creating new URLs every time a new event is listed, you risking producing a lot of near duplicates and eventually diluting your index. At best, you could have dozens or hundreds of pages competing for the same keywords.
You could canonical or 301-redirect to the most recent event, but that has trade-offs, too. For one, a huge number of either can look odd to Google. Also, the latest event may not always be an appropriate target page, especially if more than just the data is changing. Unfortunately, without seeing the content, it's really tough to tell.
The other option is to create a static URL for every pairing and update the content on that page (maybe creating archival URLs for the old content, that are lower priority in the site architecture). That way, the most current URL never changes. Again, this depends a lot on the site and the scope.
If you'r just talking about a couple of URLs for a handful of events, I wouldn't worry too much about it. I probably wouldn't reverse the URL ("A vs. B" --> "B vs. A"), as it doesn't gain you much, but I also wouldn't lose sleep over it. If each pairing can generate dozens of URLs, though, I think you may want to consider a change in your site architecture.

Thanks Jesse!
1. the content is different - according to a comparison tool they are 64% similar and considering the menus, header of the site and other element that appears on each page - you can say they're unique - don't i? even so google haven't indexed the 2nd page and it's up for 5 days - sitemap indexing rate is 90% according to google webmaster tools. so what wrong here?
2. including the date seems like a good idea! but 2 questions about it:
-won't the URL look messy with these numeric inputs?
- the same same match can be repeated in the future isn't it a good idea that the page is already indexed? i mean the URL will stay the same, just the content will be different.
Thanks,
Assaf.

Highland thanks for your quick response.
the pages are created dynamically cause at every moment we have more then 1000 matches on our DB. it's impossible to create a manual URL for each page.
the case i described is rare, but it happened for a very important match.
-
1. If the content is different then you should have no problem and you can allow both pages to be indexed without needing to noindex or canonicalize either page
2. Could you perhaps include the date in the url?
As long as each page does have different content, I would say you are fine. I would definately consider adding the date to the url. What if the two teams play again at a later date, adding the date would help differienate those pages even more and I believe help Google.

You need to better differentiate the content. T1vsT2 is not the best way to segment your content. So I would actually change URL structures to something like
www.domain.com/match/week1/T1vT2
www.domain.com/match/week2/T2vT1It better segments your content and makes it obvious there's a difference because, to an end user, the original URLs are confusing and that confusion has extended to Google. Google will not see the order as important unless you quote your search (which normal users won't do). Google matches content and context first.

301 Redirects... Redirect all content at once or in increments?
Hello, I have been reading a lot about site migration and 301s and sometimes get confused with conflicting suggestions from different sources... So, in a site migration. Should I 301 redirect all old URLs to the news at once or little by little? I've see this Google handout that suggests doing it all at once (minute 13)

Should I use a rel=canonical to the home page
Hi guys, I have a site where the homepage is ranking for the term 'industrial flooring' around position 30 and the actual level 2 industrial flooring page is ranking well below at around position 60. I'm happy for the homepage to rank for this term and would like to see it improve, so here are my questions: 1: Is the existence of the level 2 page preventing the homepage from ranking higher due to keyword cannibalization etc.? 2: Would the use of the rel=canonical tag pointing from the level 2 page to the home page have a positive or negative impact on the homepage's rankings for 'industrial flooring'? 3: Is there anything else I'm missing? Greatly appreciated.

301 Redirection problems
A couple of days ago we did a restructure of our e-commerce site (wordpress + woocomerce) where some product categories needed to change names. I used Yoast SEO plugin to do 301 redirects in the .htaccess file.Today I noticed that we had two hits in the SERP on the phrase "dildos med vibrator". See the attached screenshot (first two results).One goes to http://www.oliverocheva.se/kategori/sexleksaker/dildos/dildos-med-vibrator/ which is the right URL. One goes to http://www.oliverocheva.se/kategori/sexleksaker/dildosdildos-med-vibrator-dildos-for-honom/ which is a corrupt URL that has never been in use. The old one we did a redirect from was /kategori/for-honom/dildos-for-honom/dildos-med-vibrator-dildos-for-honom/The command in the .htaccess file was: Redirect 301 /kategori/for-honom/dildos-for-honom/dildos-med-vibrator-dildos-for-honom/ http://www.oliverocheva.se/kategori/sexleksaker/dildos/dildos-med-vibratorWhat has happened here? Why does the 301 create entirely new URL:s in the SERP?Tz0TULT.png

HTTP Header Canonical Tags
I want to be able to add canonical tags to http headers of individual URL's using .htacess, but I can't find any examples for how to do this. The only example I found was when specifying a file: http://www.seomoz.org/blog/how-to-advanced-relcanonical-http-headers N.B. It's not possible to add regular canonical tags to the of my pages as they're dynamically generated. I was trying to add the following to the .htaccess in order to add a canonical tag in the header of the page http://frugal-father.com/is-finance-in-the-uk-too-london-centric/, but I've checked with Live HTTP headers and the canonical line isn't showing : <files "is-finance-in-the-uk-too-london-centric="" "="">Header add Link "<http: frugal-father.com="">; rel="canonical"'</http:></files> Any ideas?

307 Redirect
Just checking the headers on a client site and discovered a 307 redirect. General suggestion from http status code sites is that it is similar to a 302 temporary redirect. Can someone confirm this is the case or is there a difference?

301 redirect for duplicate content
Hey, I have just started working on a site which is a video based city guide, with promotional videos for restaurants, bars, activities,etc. The first thing that I have noticed is that every video on the site has two possible urls:- http://www.domain.com/venue.php?url=rosemarino
Intermediate & Advanced SEO | | AdeLewis
http://www.domain.com/venue/rosemarino I know that I can write a .htaccess line to redirect one to the other:- redirect 301 /venue.php?url=rosemarino http://www.domain.com/venue/rosemarino but this would involve creating a .htaccess line for every video on the site and new videos that get added may get missed. Does anyone know a way of creating a rule to rewrite these urls? Any help would be most gratefully received. Thanks. Ade.0 -
How to 301 redirect ASP.net URLS
I have a situation where a site that was ASP.net has been replaced with a WordPress site. I've performed a Open Site Explorer analysis and found that most of the old pages, ie www.i3bus.com/ProductCategorySummary.aspx?ProductCategoryId=63 are returning a HTTP Status = NO DATA ... when followed ends up at the 404 catch-all page. Can I code the standard 301 Redirects in the .htaccess file for these ASP URLs? If not, I'm open to suggestions.... Thanks Bill
