Google has enough good stuff for web entrepreneurs really, I did a quick comparison of search volumes for Zain, MTN, Glo, Etisalat and got the chart above, not good for Zain really (they put bread on the table now). Zain is in marine blue and the blue topping that chart is actually MTN. It's not because Zain changed name too, the red line is Celtel so I figure the company's web presence is kind of low.
Glo is in yellow so I wonder what's going on here, anyway you got the gist, here is the live link.
Enjoy the trends you can, I compare my old name "kehinde adewusi" to "keni adewusi", google to yahoo and fried eggs to scrambled eggs.
You bring it on and let's see what's going on out there, remember to separate you keys with commas.
