When I type in "ringtone" in the keyword suggestion tool on DP, I get quite different results for Wordtracker vs. Overture. Wordtracker: ringtones 9,235 / day, ringtone 785 / day Overture: ringtone 63,395 / day Does anyone know which one is more accurate (reliable), or why there is such a huge difference?
Wordtracker and OVT use different search engines. Also, WT distinguishes between word order and singular / plural forms.
