What countries does Google crawl from? Is it only US or do they crawl from Europe and Asia, etc.?

Where does Google crawl the web from? Is it in the US only, or do they do it from a European base too? The reason for asking is for GeoIP redirection. For example, if a website is using GeoIP redirection to redirect all US traffic to a .com site and all EU traffic to a .co.uk site, will Google ever see the .co.uk site?

Hi Keith,
In my experience Google mainly crawls from the US.
You're quite right, GeoIP redirection can cause major issues with indexation - as if you're redirecting everything from the US to the .com googlebot can't see the .co.uk site.
As such, I'm not a fan. Rather than implementing a hard redirect I prefer Amazon's approach. If you visit the amazon.com site from a UK IP you get a javascript overlay that invites you to visit the .co.uk version of the site instead - they let the user decide which site to view rather than actually redirecting them.
This is a nice solution as it ensures that the search bots can crawl both versions of the site, and rankings aren't endangered.
I hope this helps,
Hannah

Keith, I am having the same issue and I agree with you. The fact that Google has data centers in Europe does not necessarily mean the algos are indexing from there. I also want to set Europe and US GeoIP redirection. It would be great to get Mozers opinions on this. Hopefully this post gets freshly reviewed

Interesting question - I'd quite like to know what happens here too.
Matt Cutts recently posted a video on cloaking (http://youtu.be/QHtnfOgp65Q) saying that as long as you don't do anything 'special' for Googlebot you're OK, but presumably if you are redirecting IP's based on location and you don't want to prevent Googlebot form accessing your site then effectively you have to do something 'special' for Googlebot (e.g. you're doing one thing for everyone else and a different thing for Googlebot).

Hi,
The data center locations is interesting, but it isn't what I was looking for. I need to know whether Google crawls the web from any IP other than US IPs.
To clear up the second question, let me be more specific:
Let's say Google is crawling a .co.uk site from a US IP address. The site is using GEO IP redirection to redirect all US traffic to the .com site. Therefore, when Google attempts to crawl the .co.uk from the US IP address site it will be redirected to the .com site, never seeing the .co.uk site. Can anyone confirm that this is what happens?
-
I found an article from 2008 that shows Google data centre locations: http://bit.ly/mONhf9
Your other question is a bit confusing. Why Google wouldn't see the UK site?

Worldwide and Europe hreflang implementation.
Hi Moz ! We're having quite a discussion here and I'd like to have some inputs. Let me explain the situation and what we plan to do so far. One of our client has two separate markets : World and Europe. Both pages versions will be mostly the same, except for the fact that they will have their own products. So basically, we'd want to show only the European EN version to Europe and the standard EN version to the rest of the world, same goes for FR and ES. As far as IT, DE, CS and SK, they will only be present within the european version. Since we cannot target all Europe with a single hreflang tag, we might have to do it for every single european countries. Regarding this subject, SMX Munich recently had quite an interesting session about this topic with a confirmation coming from John Mueller saying that we can target a single URL more than once with different hreflang tags. You can read more here : http://www.rebelytics.com/multiple-hreflang-tags-one-url/ So having all this in mind, here's the implementation we plan to do : www.example.com/en/ Self canonical www.example.com/fr/ - hreflang = fr www.example.com/es/ - hreflang = es www.example.eu/it/ - hreflang = it www.example.eu/de/ - hreflang = de www.example.eu/cs/ - hreflang = cs www.example.eu/sk/ - hreflang = sk www.example.eu/fr/ - hreflang = be-fr www.example.eu/fr/ - hreflang = ch-fr www.example.eu/fr/ - hreflang = cz-fr www.example.eu/fr/ - hreflang = de-fr www.example.eu/fr/ - hreflang = es-fr www.example.eu/fr/ - hreflang = fr-fr www.example.eu/fr/ - hreflang = uk-fr www.example.eu/fr/ - hreflang = gr-fr www.example.eu/fr/ - hreflang = hr-fr etc… . This will be done for all european countries (FR, EN and ES). www.example.com/en/ - x-default Let me know what you guys think. Thanks!

Does Google's algorithm work the same in every country?
I can't help but feel this is a silly question! but does Google algorithm work exactly the same throughout all countries? I run a few sites in the UK and a couple in Spain but can't help but feel that my Spanish sites are harder to rank for. The sites that rank the best are business directories in Spain... whereas here in the UK you'd be lucky to find one on page one..

Poor Google.co.uk ranking for a UK based .net, but great Google.com
I run an extremely popular news & community website at http://www.onedirection.net, but we're having a few ranking issues in Google.co.uk. The site gets most of its traffic from the USA which isnt a bad thing - but for our key term "one direction", we currently don't rank at all on Google.co.uk. The site is located on a server based in Manchester, UK, and we used to rank very well earlier this year - fluttering about in position 5-7 most of the time. However earlier this year, around July, we started to fall down to page 2 or 3, and at the start of this month we don't rank at all for "one direction" on Google.co.uk. On Google.com however we're very strong, always on page one. We're definitely indexed on .co.uk, just not for main search term - which I find a bit frustrating. All the content on our site is unique, and we write 2-4 stories every day. We have an active forum too, so a lot of our content is user-generated. We've never had any "unnatural link building" messages in Webmaster Tools, and our link profile looks fine to me. Do we just need more .co.uk links, or are we being penalised for something? (I can't imagine what though). It certainly seems that way though. Another site, "www.onedirection.co.uk" which is never updated and has a blatant ad for something completely unrelated on its homepage, ranks above us at the moment- which I find quite frankly appalling as our site is pretty much regarded as the worlds most popular One Direction news and fan site. We've spent the last few months improving the page-load times of our site, and we've reduced any unneccesary internal linking on the site. Approx 2 months ago we launched a new forum on the site, 301'ing all the old forum links to the new one, so that could have had an impact on rankings - but we'd expect to see an impact on Google.com as well if this was an issue. We definitely feel that we should be ranking higher on Google.co.uk. Does anyone have any ideas what the iproblems could be? Cheers, Chris.

Website Target in Europe
Hi, I am planning a site to target in Europe and I expect to translate my site into ten different languages namely English, French, Spanish, Italian, German, Russian, Greek, Portuguese, Dutch and Swedish. I am doing some study of this case in targeting different countries for SEO, most of the advise are the following: a. Build 10 different websites and target different geographical location in Google Webmaster b. Get 10 different country specific domains for 10 different websites I would like to hear any suggestion if there is anything better than this ? I had all the materials and translation ready but building 10 different websites or getting 10 different domains are very time consuming and costly. I would be appreciated if any one had any advise for me to make the website more management friendly. Thank you. Tom

How can I see what my web site looks like from a different country?
I've tried a few proxy tools to try to see how my site looks from other global locations, but haven't found one that works very well yet -- or a list of reliable proxies around the world. I need to do this to test various geo-targetted ads and other optimizations. Can anyone make a recommendation? Thanks!

Country specific landing pages
I have a client who wants to put a re-direct on his landing pages based on the visitors IP address. The landing page will be a sub domain relevant to the country their IP is located in. I am a little concerned this will effect the SEO. Appreciate any advice. Dylan 🙂
