If you want to use multiple shorteners in your website, to benefit maximum from your visitors you can use rotate scripts which loads different Full Page Script Code on each page click or refresh. I am not a coder, but I know that you can do that with javascript. Basically here is how it looks like.
You have a piece of javascript code which counts the refreshes or clicks from each unique browser session. On each next click or page reload, the code loads another different javascript code ( the Full Page Script Code generated from each shortener). I know there are some coders who visit the forum, for example @DevNagy and @Lukas are. If they can think of example of this rotation code and post a suggestion here, you must buy them some beer. :))
