Basic Definitions

Asset

Assets are the files you are selling, your products. An image is an asset, a video, a vector, an audio file or any other file on sale is an asset.

Upload

An upload is the same as an asset. It is the file you are selling.

Revenue

The amount of money generated by an asset or a set of assets.

Download

An individual sale.


RPD

What is it?

Revenue per download.

Where is it used?

We display this value for each one of your uploads in the upload's detail view. We also display it for each collection in the Collections overview and the collection's individual view.

Why is it useful?

The RPD indicates how much a customer is prepared to pay for an image. If the RPD value is high, that means that customers consistently buy larger sizes of that image. The same applies to a collection. If a collection has a high RPD, that means that customers are buying the images in large sizes, or the collection contains a good amount of premium priced images.

Some images, like landscapes and architecture images, tend to sell in large sizes, since customers buy them for print. Use the RPD to find which of your images are selling in large sizes and make sure you produce more such images, since they bring more money!

How do we calculate it?

We divide the images total revenue by the number of downloads it has. This tells us what the average revenue per download is. For collections we average the value across all images of the collection.


RPI

What is it?

Revenue per image.

Where is it used?

We display your RPI for each Collection. Go to the Collections overview or to an individual collection to find it.

Why is it useful?

Some collections have lots of images and others only have a few. To evaluate how successful a collection of image is, you want to know how much each individual image is generating. If the collection's images are good, each image will generate a lot of money. If the images are not so attractive for customers, then each image will produce a low revenue. This allows you to compare collections and identify what collections are strong. You should focus your production energy on such images.

How do we calculate it?

The RPI is calculated by dividing a collection's total revenue by the number of images in that collection.


RPI/m

What is it?

Revenue per image per month.

Where is it used?

We display your RPI/m for each Collection. Go to the Collections overview or to an individual collection to find it.

Why is it useful?

Comparing two collections is difficult, since some collections have lots of images, others less, and some have been around for a long time and others are brand new. The RPI/m allows us to break down the value of a collection into a value which can be compared across collections. We find how much revenue each image generates each month on average. This value then makes it very easy to compare two or more collections.

If for example one collection generates $2 per image each month, and another one generates $4 per image each month, then you know that the collection with the higher RPI/m contains more attractive images.

How do we calculate it?

We determine how old each image of a collection is, and then calculate how much each image has produced in each month of it's life. We average it across all images of the collection thus producing the RPI/m.


STR

What is it?

Sell Through Rate. This is a common metric in the retail business (supermarkets, clothes shops, etc…). It indicates what percentage of a collection has sold at least once.

Where is it used?

We display this value on the Collections overview and in the individual collection page.

Why is it useful?

The STR indicates how attractive your collection is. If many images have sold at least once, then you know that the collection as a whole appeals to buyers. If your collection has a low STR, that means many images remain unsold and the collection is not attractive. Explore what collections have good STR values and try to produce more images like that.

How do we calculate it?

We count how many assets in a collection have at least one download. We transform that into a percentage value which indicates the percentage of assets in a collection which have sold at least once.


STR Breakdown

What is it?

Sell Through Rate Breakdown. It is a more detailed view of the Sell Through Rate. We break down the STR displaying how long it takes for each file to make their first sale. We show what percentage of assets have sold within one week, within two weeks, within one month, within 2 months, 6 months, one year and never sold.

Where is it used?

You find the STR Breakdown for each collection in the collection's individual view.

Why is it useful?

The STR as described above has the disadvantage that as a collection grows older, the more files have at least one sale and the less meaningful the STR percentage value becomes. It converges towards 100% and then it becomes useless. That's why the STR breakdown is very useful regardless how old a collection is.

You can see in the STR Breakdown chart how long it takes for the collection's assets to make their first sale. If your files sell within a short time after upload, that means that they are very appealing to customers. If they don't sell very fast, then you probably have an unappealing collection.

How do we calculate it?

We check for each image what its upload date is and what its first sale date is. This tells us how long it took for that image to sell for the first time. We use that information to build the chart.


Fotolia Credits

What is it?

Fotolia's system currency is based on their own credits. Fotolia contributors see their earnings in credits and not in dollars. Your credits can be based on Euro or US Dollars.

Where is it used?

We do not use Fotolia Credits in Stock Performer. We convert the credits to dollars based on the credit conversion rate you configured when signing up to Stock Performer.

Why is it useful?

It is important that you configure the Stock Performer rate in accordance to your Fotolia configuration. Like that we will display your correct earnings in our charts.

How do we calculate it?

For those contributors who have their Fotolia credits based on Euro, we calculate the dollar conversion based on a fixed Euro to US Dollar rate.
