Do i use more than 400 track keywords


I have track keywords, dynamically changed by users. sometimes 800-900 sometimes more than 900-1000 keywords.

1- “The default access level Allows up to 400 track keywords” writes in the documentation. which means that an application can track a maximum of 400 keywords or per a connection can track a maximum of 400 keywords?

2- how can i track these keywords?

such as do I open one connection per 400 keywords if i can single application or i cant create a application per 400 keywords
