We pay close attention to Google search results page (SERP) and how it is being changed because that directly affects our website performance, traffic and click-through. I have already had a look at how Google search result listing was evolving. Today we’ll look at another essential phenomenon in Google SERPs: clustered results (used to be referred to as “host crowding“).
What are “Clustered” Google Search Results?
Or, in other words, why are some results get clustered?
If one domain gets two pages ranked in top 10 results, Google would unite those two listing in the “clustered” one.
According to Google:
Indented results
When Google finds multiple results from the same website, the most relevant result is listed first, with other relevant pages from that site indented below it. If we find more than two results from the same site, the remaining results can be accessed by clicking the More results from link.

Obviously, indented results are usually given for long-tail, less competitive search terms.
Clustered (or indented) listings have been around for ages. They have been changed slightly several times:
- For branded search results indented listings were substituted with “stacked” domains (where many pages from the same domain are returned without any clustering);
- Forums got multiple “mini”-indented results for multiple related threads;
- Google experimented with multiple indented results for the same domain.
Note: I usually don’t recommend trying to “force” an intended result for your own domain because promoting two pages from your domain for one key term may result in triggering duplicate content filter. The best intended result is the one that comes naturally. But if you have a page ranked in top five for some search term and another page ranked within 11-20 range, you have a good chance.
Is there a Way to “Uncluster” Those Results?
“Unclustering” those results can discover some highly important opportunities for you:
- How easy it would be for you to push your competitor down;
- How easy it would be for you to get higher.
To learn the real position of the indented result, take advantage of &num=1 Google search URL parameter: it forces Google to display one result per page and thus puts the indented listing at it actual spot. The great example of this tip in action is this thread:
I’ve been #3 and #4 for my favorite keyword for a long time, while another site has been #1 and #2 for as long as I can remember. In unclustered results, I’m #2 and #5 while he’s *1 and *3. These unclustered ranks show that I’m fairly close to getting the #1 spot (I wouldn’t be close if he had both *1 and *2).
Let’s exercise.
Taking the example in the very first screenshot, we see the first listing from the cluster on page 1 (obviously):

While the second indented result comes only on page 8 (which means it is fairly easy to push it down!):

This means that our initial screenshot should actually look like this:

Is there a Tool for That?
Not exactly a tool but a very handy way to speed up the process. This browser bookmarklet (courtesy of Squarefree) will add &num=1 to any Google string once you click it:
(Just drag it to your browser bookmarks toolbar).
The bookmarklet is compatible with FireFox, Internet Explorer and Google Chrome.

Thanks for the tip Ann.
Do you know the cut-off where Google won’t indent the second result? Is it once it’s no longer on page 1?
Yes, Robert, two results will be clustered as long as they are on page 1
Robert,
Yes when the second result is no longer on the same page as the first result, there will be no indent. Actually, I’ve been seeing a lot of double results stacked like that but without an actual indentation of the second result. It could just be a visual thing Google is testing.
Ann I tried that parameter on several searches and it didn’t work for me. I tried manually adding it, as well as using the bookmarklet. I tried using it with and without PWS=0 too. I’ll fiddle around a little more and go read that thread. Maybe I’m not doing something correctly.
Ah ha… you have to turn off Google Instant.
Yes
Glad you figured it out before I was able to tune in
do you think with these results this means its more and more important to be in the top ten. Its seems like a shift in the search engine can appeal to more people with a mixture of things.
Hey Brent, it’s always been important but with Google Insant it’s almost the only way to go…
Ann,
so if I am not wrong, only the site listing just below the indented result is the one which can topple the indented result, correct? Also, I would believe that in case a second result is ranking in top 10, either the
1.SERP competition is less (a long tail, informational query).
2. the authority of the site with indented result is extremely high.
3. The query is brand oriented.
Yes Google is the best. I like Google and its products and I am always crazy about that
