What exactly are those indented results all about?

Just puzzling me

[Dino_M]

I know you have all seen indented results on Google can anyone give me an explanation of why they occur?

[edit_g]

They are results from the same site as the search result above (I believe).

[korkus2000]

It is site clustering. As edit_g says it is a result from within the same domain. It lets searchers have a lot more choices instead of 5 pages of the same site.

[Dino_M]

Yep I got that bit,

but why do they sometimes occur?

I have a site who's home page is ranked number 1 for widgets and it has an indented result that goes to my other page on the site about the history of widgets.

I like this double result but it only occurs for the keyword widget when someone types in blue widgets, I'm number 1, with my blue widget page, but there is no indented result for my history of blue widgets page. WHY?

hope that makes some sense.

[korkus2000]

Both pages need to be high rankers for that key phrase. The other serps that don't give you a cluster didn't have any high ranking secondary pages for that phrase.

[Dino_M]

I see,

so if I had results say 1st and 5th from the same site chances are they would be combined into result 1 indented 2 !

[korkus2000]

Yes I belive thats how it works. I don't know how far down you can yank a result though.

Does anyone now how to turn it off? Preference or URL variable?

[korkus2000]

This aol search uses unclustered google results
[aolsearch.aol.com...]

[edit_g]

I don't think you can turn it off. I tend to find it quite useful (especially when they are mine). There is nothing quite like having 1 and 2 on a keyword that you've been slaving away at.

Note- That sounded really sad, didn't it. There are lots of things that are better- but I'm sure that if you're reading this, you know what I mean... ;)

[Dino_M]

not much better than a number one and number two result ! :)

I might start optimising two pages for every keyword, any one think that is worth the effort?
