Frequently asked questions
What does the byte calculator do?
It counts the UTF-8 bytes of each keyword and of the whole list, and shows the line where your byte limit is exceeded.
Which byte limit is preset?
The preset is 249 bytes. You can change it to match the requirement for your marketplace and product type.
Why bytes instead of characters?
Special characters such as umlauts take more than one byte in UTF-8, so a list can have more bytes than characters.
Are my keywords stored?
No. Everything is calculated in your browser.
