Measuring Web Site Performance
The issue is how to measure search, to provide our clients with an objective measure of their performance on the major search engines. (Google, Yahoo and MSN count for over 92 percent of all U.S. search traffic.) This is becoming more important as studies show that, in the business-to-business market, over 75 percent of purchasers searching for a new solution begin their search on the web.
To describe our solution, the Total Available Search Market metric, or TASM, we need to take a step back and review what occurs when somebody uses a search engine to find a solution. Typically they open up a search engine, often Google (often 60-70 percent of b-to-b searches), input a search phrase of two to four words and get a whole bunch of search results back – often millions of listings assembled ten at a time on separate pages. The searcher then clicks on listings until they find what they are looking for – to the searcher, the efficiency of a search engine is probably measured by how few listings they need to explore to find what they are looking for.
So how do we measure this process? It is important to know that the number of incidences of search phrases is carefully measured. We use Overture and WordTracker to evaluate our clients’ potential search phrases to find the best candidates.
Also, there has been considerable research on the “readership” of each page of search results – in the B2B arena, we believe 100 percent of searchers read the first three listings, 90 percent review listings four through ten, and 50 percent see the second page of listings 11 through 20. After that, readership declines rapidly – only 10% of searchers reach the third page.
So it is fairly easy to see how our metric works: we make a list of our client’s search phrases, measure the number of times that phrases was used in the course of a month, measure the client’s position on a search listing for that phrase, and do the math to measure out how many people will see the client’s listing when they input a particular search phrase. Here's a link to a sample search engine ranking report. In search marketing, visibility is the key index.
For example, one of RefreshWeb’s keyword phrases is “b2b marketing agency,” which gets 300 searches a month across all the major search engines. At this writing, we are number seven on Google, MSN and Yahoo for this phrase. Ninety percent times 300 is 270 persons – that is how many people are exposed to RefreshWeb when they use a search engine to find a “b2b marketing agency.”
The math is easy – what is not immediately intuitive is the reality that creating a useful metric means not trying to do too much. What makes for good marketing intelligence is “actionability” – a metric that is too reductive reduces the ability of our clients to act on the data we are giving them.
For practical purposes, this means fighting the very human desire to appreciate the “horse race” and aggregate the data (with a weighted average) into a single “score” that rates the performance of the client’s website. We need to keep our eyes trained on the performance on the important keyword phrases in order to have a sense that we are attracting the “most, right” traffic to the website (that comma between “most” and “right” is no accident).
There is an apt metaphor in one time-honored way to create a sculpture. The sculptor will sometimes create a clay model of the finished work and submerge it in water, progressively removing the water to expose the next horizontal plane that needs to be sculpted. The restricted view allows the artist to focus on the next few strokes of the chisel – very important when a single errant stroke could destroy the entire project.
While the risks aren’t the same when optimizing a website, that kind of focus – keyword by keyword – is critical to developing an effective natural search strategy. It is even more important when adjusting and tweaking the website.
In the next article we will look at developing, and adjusting, your keyword strategy to capture just the right market that makes sense for your business.
