The 250-Byte Tool helps you to keep your back-end keywords within the maximum permitted data volume of 250 bytes.
What is a byte?
Simply put: data volumes are measured in bytes. The more bytes a file "weighs", the more storage space it consumes. Surely you are familiar with storage space specifications such as "32 gigabytes" in regard to smartphones, USB sticks or cloud storage. The following applies rule applies here: the more bytes, the more data can be stored on the respective data carrier. 32 gigabytes correspond to 32 billion bytes.
Back-end keywords on Amazon
Amazon allows back-end keywords with a maximum data volume of 250 bytes per listing. Most letters occupy 1 byte of storage space - but special characters and umlauts occupy 2 bytes or more. It is therefore difficult to estimate how much storage space the back-end keywords already occupy and whether there is enough space for additional keywords. This is where the 250 byte tool comes in handy.
💡 Even if your back-end keywords are already below the permitted 250 bytes, it may be worth checking them for duplicates with the 250 byte tool - this may free up space for additional keywords.
How to use the 250-Byte-Tool
Enter your back-end keywords in the array labeled "Text". The "KPIs" section shows you in real time how many keywords the field contains, whether it contains duplicates, how many characters you have entered and - most importantly - how many bytes your keywords are occupying.
With a click on the button "Remove Duplicates" you can automatically delete duplicate keywords. Together with the byte counter you are able to easily stay below the Amazon limit of 250 bytes.
