What's the most important feature that you like in certain SERP trackers? Why you use that tracker?

I'm working hard with my team on an website that will do SERP tracking and i want to integrate there things that matter for specialists.

SEO's, please write something. Really need to know what you appreciate most.

Regards,

I often use a keyword rank tracker that is known as SEOcentro which seems to a pretty good one. The thing that I like is that it tells where your site is ranked from the three major search engines. But, the result is limited up to the 5th page.
