Best practice to redirects based on visitors' detected language
-
One of our websites has two languages, English and Italian.
The English pages are available at the root level:
www.site.com/ English homepage www.site.com/page1
www.site.com/page2The Italian pages are available under the /it/ level:
www.site.com/it Italian homepage www.site.com/it/pagina1
www.site.com/it/pagina2When an Italian visitor first visits www.mysit.com we'd like to redirect it to www.site.com/it but we don't know if that would impact search engine spiders (eg GoogleBot) in any way...
It would be better to do a Javascript redirect? Or an http 3xx redirect? If so, which of the 3xx redirect should we use?
Thank you
-
We've adopted the following solution:
we show the English homepage, but we determine the user's preferred language (from the Accept-Language header sent by the browser). If our site supports that language, we show a temporary balloon that highlights the related link to go to the localized homepage.
Thank you all for your hints and notes.

I would stay away from javascript redirects as it can be considered cloaking. Best thing to do is have a page for new visitors (those not having your cookie) and send them to a page that allows them to choose what language they want. You can then set a cookie so when they return it will automatically direct them to the right site.
By not doing any sneaky javascript redirects or IP redirects, you allow google the ability to crawl all the pages of your site and improve indexing, trust, etc etc... Also, I would go into Google webmaster tools and specify the country your /it pages are directed to. This will help in international search and trust from Google.

I've done a test with a simple ASP page with a Response.Redirect: <% Response.Redirect "test.htm" %>
This is what Fiddler has catched: HTTP/1.1 302 Object moved Server: Microsoft-IIS/5.1 Date: Thu, 05 May 2011 06:44:10 GMT X-Powered-By: ASP.NET Location: test.htm Content-Length: 121 Content-Type: text/html Cache-control: private <title>Object moved</title>
Object Moved
This object may be found <a href="">here</a>.
I don't think that 302 would be the best solution. As specified in the HTTP specs ( http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html ) wouldn't we prefer a 307 Temporary Redirect?
Thank you

You also asked about which 30x redirect to use. I'm also looking for this answer. We currently an ASP header redirect. I don't think this is best, but I'm not sure a 301 redirect can be used. I'd like to hear from others too.
This is what we have now:
lang = Request.ServerVariables("HTTP_ACCEPT_LANGUAGE")
real_lang = Left(lang,2)
'Response.Write real_lang
Select case real_lang
case "en"
Response.Redirect "/en"
case "fr"
Response.Redirect "/fr"
case "de"
Response.Redirect "/ge"
case else
Response.Redirect "/en"End Select

They automatically redirect people in the uk who type in www.google.com to www.google.co.uk
But, this is different from changing language on a visitor. I'm not sure what google would do if I was in Italy and used my american laptop to visit google.com. I don't think they'd switch me to www.google.it, but maybe someone else has this answer.
Using the browser language settings has worked well for us.

You might want to look into what Google do themselves.
They automatically redirect people in the uk who type in www.google.com to www.google.co.uk
If it's good enough for google it's good enough for us. Just make sure you do not look like you are cloaking.
You need to give users the ability to change language when they are on the website though. As Vince mentioned just because a user is visiting the website from Italy it does not mean that they are Italian.

Hi Daminao,
I do a redirect based on browser language. I'd stay away from IP/location based redirects. You can have English vistors in Italian locations that would be lost on your pages.
hth,
Vince

301 Redirects for Multiple Language Sites in htaccess File
Hi everyone, I have a site on a subdomain that has multiple languages set up at the domain level: https://mysite.site.com, https://mysite.site.fr , https://mysite.site.es , https://mysite.site.de , etc. We are migrating to a new subdomain and I am trying to create 301 redirects within the htaccess file, but I am a bit lost on how to do this as it seems you have to go from a relative url to an absolute - which would be fine if I was only doing this for the english site, but I'm not. It doesn't seem like I can go from absolute url to an absolute url - but I could be wrong. I am new to editing the htaccess file - so I could definitely use some advice here. Thanks.

Faceted Navigation URLs Best Practices
Hi, We are developing new Products Pages with faceted filters. You can see it here: https://www.viatrading.com/wholesale-products/ We have a feature allowing to Order By and Group By, which alters the order of all products. There will also be the option to view Products as a table, which will contain same products but with different design and maybe slightly different content of each product. All this will happen without changing the URL, https://www.viatrading.com/all/ Is this the best practice? Thanks,

Splitting One Site Into Two Sites Best Practices Needed
Okay, working with a large site that, for business reasons beyond organic search, wants to split an existing site in two. So, the old domain name stays and a new one is born with some of the content from the old site, along with some new content of its own. The general idea, for more than just search reasons, is that it makes both the old site and new sites more purely about their respective subject matter. The existing content on the old site that is becoming part of the new site will be 301'd to the new site's domain. So, the old site will have a lot of 301s and links to the new site. No links coming back from the new site to the old site anticipated at this time. Would like any and all insights into any potential pitfalls and best practices for this to come off as well as it can under the circumstances. For instance, should all those links from the old site to the new site be nofollowed, kind of like a non-editorial link to an affiliate or advertiser? Is there weirdness for Google in 301ing to a new domain from some, but not all, content of the old site. Would you individually submit requests to remove from index for the hundreds and hundreds of old site pages moving to the new site or just figure that the 301 will eventually take care of that? Is there substantial organic search risk of any kind to the old site, beyond the obvious of just not having those pages to produce any more? Anything else? Any ideas about how long the new site can expect to wander the wilderness of no organic search traffic? The old site has a 45 domain authority. Thanks!

Best-practice URL structures with multiple filter combinations
Hello, We're putting together a large piece of content that will have some interactive filtering elements. There are two types of filters, topics and object types. The architecture under the hood constrains us so that everything needs to be in URL parameters. If someone selects a single filter, this can look pretty clean: www.domain.com/project?topic=firstTopic
Intermediate & Advanced SEO | | digitalcrc
or
www.domain.com/project?object=typeOne The problems arise when people select multiple topics, potentially across two different filter types: www.domain.com/project?topic=firstTopic-secondTopic-thirdTopic&object=typeOne-typeTwo I've raised concerns around the structure in general, but it seems to be too late at this point so now I'm scratching my head thinking of how best to get these indexed. I have two main concerns: A ton of near-duplicate content and hundreds of URLs being created and indexed with various filter combinations added Over-reacting to the first point above and over-canonicalizing/no-indexing combination pages to the detriment of the content as a whole Would the best approach be to index each single topic filter individually, and canonicalize any combinations to the 'view all' page? I don't have much experience with e-commerce SEO (which this problem seems to have the most in common with) so any advice is greatly appreciated. Thanks!0 -
Mega Menu Navigation Best Practice
First off, I'm a landscape/nature/travel photographer. I mainly sell prints of my work. I'm in the process of redesigning my website, and I'm trying to decide whether to keep the navigation extremely simple or leave the drop-down menu for galleries. Currently, my navigation is something like this: Galleries
Intermediate & Advanced SEO | | shannmg1
> Gallery for State or Country (example: California)
> Sub-region in State or Country (example: San Francisco)
Blog
Prints
About
Contact Selling prints is the top priority of the website, as that's what runs the business. I have lots of blog content, and I'm starting to build some good travel advice, etc. but in reality, the galleries, which then filter down to individual pages for each photo with a cart system, are the most important. What I'm struggling to decide is whether to leave the sort of "mega menu" for the galleries, or to do away with them, and have the user go to the overall galleries page to navigate further into the site. Leaving the mega menu intact, the galleries page becomes a lot less important, and takes out a step to get to the shopping cart. However, I'm wondering if the amount of galleries in the drop down menu is giving TOO many choices up front as well. I also wonder how changing this will affect search. Any thoughts on which is better or is it really just a matter of preference?0 -
Membership/subscriber (/customer) only content and SEO best practice
Hello Mozzers, I was wondering whether there's any best practice guidance out there re: how to deal with membership/subscriber (existing customer) only content on a website, from an SEO perspective - what is best practice? A few SEOs have told me to make some of the content visible to Google, for SEO purposes, yet I'm really not sure whether this is acceptable / manipulative, and I don't want to upset Google (or users for that matter!) Thanks in advance, Luke

What Happens If a Hreflang Sitemap Doesn't Include Every Language for Missing Translated Pages?
As we are building a hreflang sitemap for a client, we are correctly implementing the tag across 5 different languages including English. However, the News and Events section was never translated into any of the other four languages. There are also a few pages that were translated into some but not all of the 4 languages. Is it good practice to still list out the individual non-translated pages like on a regular sitemap without a hreflang tag? Should the hreflang sitemap include the hreflang tag with pages that are missing a few language translations (when one or two language translations may be missing)? We are uncertain if this inconsistency would create a problem and we would like some feedback before pushing the hreflang sitemap live.

ECommerce product listed in multiple places, best SEO practice?
We have an eCommerce site we have built for a customer and the products are allowed to appear in more than one product category within the web site. Now I know this is a bad idea from a duplicate content point of view, But we are going to allow the customer to select which out of the multiple categories the product appears in will be the default category. This will mean we will have a way of defining what the default url is for a product. So am I correct in thinking all the other urls where the product appears we should add a rel canonical to these pages pointing to the default url to stop duplicate content? Is this the best way?
