ISP effects ranking

[johan]

Why have not read about this. When I am at home my site is listed 2nd in Google.co.uk and my ISP is NTL. When I go to work my site is not in the Google.co.uk results (ISP is Zen) due to the www/non-www issue!?

What is going on?

Johan, I don't think it should be a www/non-www issue. I'd suggest checking the search preferences, especially if you have it restriced to something (like UK-only). It might also be possible that Google thinks that your work or home IP is not based in the UK and shows you differently geotargeted results.

I have done this already. In fact I copied not just the query string but the whole URL and sent it to work ISP in real time where a work colleague confirmed that the site was not there. Google does show deferent results on some ISP’s.

It's called geo targetting /preference ..and even if you switch off the country preference it still happens ..this is why when you are watching a particular dc ..and being very webmastery clever ..bear in mind that most of your visitors are just opening their browser and typing in the first google search box that they get ..

Thats the one you optimise for ..if you are in Germany and want Germans to buy from you cos they found you on page one ..

some ISP's actually run your service from outside of your country ..

extrapolate ..

This is a .co.uk domain. Both my .co.uk of which one unaffected is the only one to be physically hosted in the UK.

It is even more complicated than physical location of server. I have a .com site but that is unaffected by geo both ISPs. (but it does not show in "pages from the uk" on both because it not physically in the uk).

Ping Google.co.uk from Home and from Work - you are probably just accessing different DCs - one has your site the other doesnt?

[Johan007]

DOH! Yep google.co.uk using NTL just seem to take a week longer than other ISP's to update. Just checked the results and they are only just now the same.

Same happened on the bourbon update.

[Johan007]

LOL now NTL are showing my site again and the other ISP not. I am going to test these results on more than 2 ISPs.

[Gary_Numan]

So do different ISP companies send visitors to different Google DCs?

Can't see how that works!

Just ran a tracert on google.co.uk and it went to 66.102.9.99 and I am on NTL. My mate 40 miles away is on BT. Asked him to do the same trace and it brought the same result.

They may take different routes, but they always end up at the same place don't they? It's up to Google to point to a DC based on the domain typed in, not the ISP surely.

Would only bring different results if you are physically typing in IP numbers in my view.

Sorry, can't understand.

Happy to be proved wrong on this.

My traffic is good with NTL and the stats are good so must be just Zen ISP showing deferent results.

i am wondering the same thing

my site is no3 on NTL at home and no.14 on ntl at work (6 miles away) is it possible they are able to geo-locate locally as my site appears for "blue widgets town" with the town being where my NTL connection routes through? my work one seems to go through a connection down south....

As Dayo_UK said, different dcs and there is a state of flux going on. Even refreshing the search can bring different results.

[Johan007]

I don’t think is as sophisticated as geo targeting but its just another variable we must look at before jumping onto conclusions. At work my site still does not appear properly and appears “sandbox or penalised” way down in the rankings or not at all but at home they are still continuing in the number one or two spots for every page. Its not fluxing that much and its been weeks like this.
