There are a number of new metrics in the LookStat Analytics upgrade and I wanted to define them and point out how they can help you identify areas of opportunity in your portfolios. When you combine these with LookStat Collections, you can really start to get in and pull things apart to discover insights that will save you money and help you plan more profitable shoots. More on this coming soon. First, I wanted to define some of the metrics that you’ll see.

Revenue Per Image (RPI)
Why it Matters:
Allows you to calculate the earning power of an individual image or group of images. When you combine this with collections, allows you to compare shoots and concepts in an apples to apples fashion. For example, if you have a business shoot & a lifestyle shoot with slightly different image counts, the RPI of the shoot allows you to see which of them earns more per image and you can then use this information to compute your return on investment for the shoot.
How We Calculate It:
This is calculated on a daily and a monthly basis. The monthly calculation is Earnings for the Month/Images Online at the end of the month. This is then averaged over the timeframe being viewed. So, if you are viewing ‘This Year’ than the average monthly RPI refers to your monthly RPI average for 2010.
The daily RPI number is calculated as follows: Day’s earnings/Images Online that day. This too is averaged over the timeframe being viewed. Our view is that the daily number is the most accurate because it takes into account any uploading variations during the month. For example, if you uploading 1 image per day for 29 days and then uploading 500 on the 30th day, the montly RPI would skew very low which the average daily number would be more accurate. We are looking for feedback on this so I’d love to get your thoughts.
Sell Through Rate (STR)
Why It Matters:
Sell through rate allows you to see the overall commercial viability of your portfolio or your collection. If you have 100% sell through rate, that means every single one of your images has had at least one sale. This means that you didn’t shoot, retouch, keyword, upload & submit any images that no one bought. This is a good thing. If you find that certain shoots in your portfolio have low sell through rates, you are investing time and money in images that don’t interest buyers. Naturally, sell through rate is time dependent – for example, if you upload a 100 image shoot, it may take some time before all of those images see the light of day. Tracking STR after 90 days across different shoots for example is a good way to compare how they are doing relative to each other.
How We Calculate It:
We compute a daily STR (number of unique images that sold/images online that day) and a ‘Period STR’ which is the same calculation for the time period that you are viewing. Ideally, both numbers trend towards 100%. It’s normal for your daily value to be much lower than when you view All-time STR, for example. We’ll be working on some benchmarking data so you can start to see how
Trailing 30 Day Moving Average (T30)
Why It Matters:
This is the monthly trend and it smooths out the daily and weekly fluctuations associated with the normal weekly cycle of sales. When you overlay this on a chart showing weekly earnings, for example, you can see the general trend and how periodic peaks and valleys are affecting it. In the chart below, the orange line is the T30 earnings while the red line is the weekly earnings.

How We Calculate It:
As the name suggests, it is a moving average of the last 30 days. Our system also calculates the moving average of the last 7 days but we don’t currently display this. We felt the T30 line showed a better trend but we’re open to changing this. Please let us know what you think.
