Let me know when the book is out:
“Top 3 KPIs in Marketing & Sales. And How to Improve them.”
If you include your food-for-thought below, you may be quoted and/or interviewed, and you’ll definitely get a soft-copy for free:
3 Key Performance Indicators? But they must differ immensely from one company to another?!
Nope, they differ slightly less than you may think.
You'll get to read about the KPIs in the book.
A hint: All businesses must optimize the simple formula:
Contacts x Conversions x Customer Retention
...so the KPIs can all be derived from it.
Perhaps you'll have some more feedback on what I should include?!
