On Friday, we launched our new keyword tool: Concentrate. One of its key features is a scalable algorithm that automatically discovers patterns in large amounts of search data and clusters long tail queries into manageable groups. This post will explain how using Concentrate’s pattern discovery feature can simplify search data analysis and give you an edge on the competition. To explain how valuable Concentrate’s pattern discovery can be, we put together a case study of the travel sector using the Plus version of Concentrate and the type of competitive search data available from commercial providers like Hitwise or Compete. We will go into the details tomorrow, but here is a sneak peek at the results. This chart shows the share of travel searches by site in Spring 2006 and was generated using reports downloaded from Concentrate pattern discovery:
Travel Sector Searches: Comparing sites by pattern share
The Long Tail of Search
Search analytics starts by looking at the most frequent search queries driving traffic to your site or that of your competitors (these are often called the "head queries"). For most sites, these queries are a fraction of your total search traffic and just the tip of the iceberg in terms of insight about your audience. Queries like "cheap hotels in liverpool ny" may only occur once or twice in a given month, but when aggregated with other rare phrases can make up the bulk of your traffic.
The concept of the long tail in business intelligence has been a topic of debate over the last few years. One area where the long tail is alive and well is in search. The landscape of user search queries is dominated by the long tail, and most studies indicate that referrals from these long tail phrases are more likely to lead to purchases on your site. Natural search isn’t the only area where the long tail turns out to be critical. Paid search efforts which ignore the long tail are potentially missing out on a large chunk of revenue. The challenge of the long tail is that dealing with massive amounts of query data quickly becomes unmanageable.

If you have hundreds of pages of unique queries to sort through manually, forming a actionable view of that data is a painful process. This is why most people only look at the first few pages of queries.
Categorizing Queries using Patterns
Finding frequent search patterns is the key to making search data understandable. Patterns let you to treat groups of long tail searches like popular individual queries.
Our concept of patterns is similar to an example described by Brian Brown in a recent SEOMoz post. Patterns are templates for searches that have a similar structure. For instance, the pattern “jobs in [x]" represents searches for jobs in some location. The “[x]" is a wildcard that can stand for one or more words. These “masked terms" are often variants of a similar concepts, like locations or celebrity names. Depending on the nature of your site, up to 80% of your long tail search traffic could be summarized using just the top 20 query patterns.

The next iteration of Concentrate’s learning algorithms will replace many of these wildcards with named entity labels. For example: “hotels in [x]" will become “hotels in [City]". See our FAQ for more details on special pattern categories like navigational queries. Tomorrow, we’ll cover the travel case study in detail.
