My favorite session at SMX Advanced last month was โ€œGive It Up,โ€ the session where panelists shared little-known secrets. Iโ€™m a little biased, since that was the panel I spoke on. But still, as the last session of the two days, it really ended the conference with a bang. For those of you who didnโ€™t attend, there was a 30 day moratorium on blogging/writing about the session. Today marks the end of that embargo period, so without further ado, hereโ€™s the secret:

You probably know that Google will group two results together when they are both from the same siteโ€”indenting the second of the two results indented beneath the first one. Letโ€™s say, for sake of argument, that a competitor of yours is ranked #1 and #2. But did you know that the listing ranked #2 is most likely not actually #2, rather something between #3 and #10? The second, indented result could very well have as its โ€œtrueโ€ position #10. If thatโ€™s the case, the second listing is much more susceptible to getting bumped on to page two of the Google SERPs. And if that happens, your competitor goes from having two listings on the first page to having only one. Nice!

And do you know how to ascertain the true position of an indented (grouped) result? Simply append &num=9 to the URL of the Google SERP, to show results 1-9 instead of 1-10, and see if the indented listing drops off. If it doesnโ€™t, revise &num=9 to &num=8. Continue iterating downward until the indented listing falls away.

Letโ€™s look at an exampleโ€ฆ

A search on Google for โ€œscience experimentโ€ returns one of our (Netconceptsโ€™) clients at #1, as evidenced in the screenshot above. But notice the competitor at positions #2 and #3. Letโ€™s say we wanted to take out that competitorโ€™s second listing (i.e. position #3). First we need to determine what the true ranking is of that indented listing. We do this by appending &num=9 to the Google URL, like so:

Hmm. Both listings are still there. Time to try &num=8 instead, like so:

Bingo! The indented search result is goneโ€”relegated to page 2. That must mean that the true position is 9, not 3.

Armed with this new information, I then review whoโ€™s positioned near the top of page 2 and decide who Iโ€™m going to help onto page 1 to bump out the competitor. In this case, itโ€™s a no-brainer who to give a boost toโ€”our client is also at position 12 (albeit with a different page):

Thereโ€™s an extra bonus hereโ€”this #12 listing, if it makes it onto page 1, will end up getting grouped at #2, right under our clientโ€™s #1 ranking. Including the phrase โ€œscience experimentโ€ into this pageโ€™s title tag is an obvious first step towards bumping this listing onto page 1.

Because the competitorโ€™s second listing has 9 as its true position, I would need to push two listings from page 2 to page 1 in order to kick the competitorโ€™s second listing to page 2. Whereas, if it were truly #10 instead of #9, we would have only needed to push one. So we will also need to send some โ€œjuiceโ€ to a noncompeting siteโ€”such as the one at #11. We do that simply by linking to it. Itโ€™s especially handy if thereโ€™s a relevant Wikipedia article you can push onto page 1, because you can wield Wikipediaโ€™s super-powerful internal linking to give it the boost (e.g. through links from Categories, Disambiguation pages, related articles).

So there you have it: a way to determine the โ€œtrueโ€ Google ranking of an indented (grouped) result, and a hypothetical approach to making tactical use of this competitive intelligence.
