Google Sitelinks Expansion: Early Results in Traffic Funneling

As you probably recall, Google rolled out an enhanced version of Sitelinks in mid-October. I thought it would be interesting to monitor the early results and see how effective the new links are.

Following is a typical example of Sitelinks. Google now shows up to eight links instead of the maximum of four that it showed only a month ago. When I refer to traffic later in the post, these Sitelink numbers are the links/URLs I'll be talking about:

Anatomy of a Sitelink structure

The point of this post is to show you what happened (if anything) to the traffic that had traditionally funneled to either the main link or to the four Sitelinks. I plotted traffic to each of the nine links through October to see what would happen. the following charts reflect these filtered criteria:

  • The query term was a single word
  • The referrer was Google (organic)
  • The entry page was the exact URL of the link being discussed

In addition, here are some important caveats:

  • These charts are NOT all the same scale; I can't give actual visit numbers, but I will give the percent of all clicks received. The "main" link, as well as Sitelinks 1-3, pull in some serious numbers. While the traffic spikes in Sitelinks 5-8 will look pretty large, they shouldn't be construed as having the same traffic numbers. More on that as I discuss each link.
  • Don't necessarily infer any proposed correlation between drop in traffic to one link and rise in traffic to another. These things are controlled by many, many more factors than the mere existence of new Sitelinks.
  • The Sitelinks change was announced around 10/18, but it took a while to roll it out to all DCs. I didn't see it for any searches until at least the 25th. Keep a gradual rollout in mind when you look at the charts for links 5-8.

Okay, here we go. Following are descriptions of each link followed by a graph of the traffic to that link for October.

URL/Sitelink 0: The "main" link -- represented by "Company Name and Stuff" in the shot above. A slight drop overall, but it appeared to happen across the month, not necessarily at the same time as the Sitelinks rollout. Total traffic: 67.6% :

October traffic for the 'main' link

URL/Sitelink 1: The first true "Sitelink" link. A slight decline throughout the month, but again, not necessarily correlating to the Sitelinks rollout. Total traffic: 25.2% :

October traffic for Sitelink 1

URL/Sitelink 2: Like the previous two links, it declined slightly. It looks a little more aligned with the rollout, but not completely. Total traffic: 5.1% :

October traffic for Sitelink 2

URL/Sitelink 3:This link actually showed modest gains, starting about the time of the rollout. Total traffic: 1.6% :

October traffic for Sitelink 3

URL/Sitelink 4:In early October, this link was already coming down from an offline push that peaked in late September. But the Sitelinks rollout didn't seem to help it, as it shows additional decline after the rollout period. One additional thing about this link: It's not what you'd traditionally think of when you type "keyword," so I attribute a lot of its clicks to curious onlookers who didn't expect to see it there. The other side of that sword is that now, the query shows four new, shiny links in the other column that will continue to drain clicks away from this guy. Total traffic: .22% :

October traffic for Sitelink 4

URL/Sitelink 5:Okay, the first of the new links. From out of nowhere, it starts getting traffic on 10/17. But not that much. Total traffic: .12% :

October traffic for Sitelink 5

URL/Sitelink 6:Like Sitelink 5, this one really jumped when the rollout started. It had just a few clicks before the rollout for this query, because this URL also ranks for "keyword" on its own somewhere beyond Page 2. Total traffic: .07% :

October traffic for Sitelink 6

URL/Sitelink 7:In addition to its new location as Sitelink 7, this URL also lives above the fold on Page 2 for the same query. Since the Sitelinks rollout, it's on a pace to roughly triple its former traffic (for this keyword only, of course). Total traffic: .06% :

October traffic for Sitelink 7

URL/Sitelink 8:This link came from nowhere, but it didn't do much. Part of it might have to do with being in the eighth spot, but more likely it's because I believe this particular link doesn't interest people who are searching for "keyword." Total traffic: .02% :

October traffic for Sitelink 8

Required disclaimers. This click distribution across the nine links (main link plus eight Sitelinks) is highly variable and will change depending on what Google picks for your Sitelinks, how well the links match the query itself (and the intent of the searcher), etc.

The interesting thing for me here is not that Sitelinks 5-8 are getting clicks. That's not newsworthy. But from a behavioral perspective, it's interesting to watch how users react to links they might not have expected to see associated with their query.

One final note: These eight links are the ones that Google auto-generated. We'll be doing more posts about the ability to subtly affect the Sitelinks choices in the future.
