Is yahoo cheaper then google ?

yahoo's probably cheaper because more people use google nowadays. google adword is good and effective.

I am not really sure never used their services.

People use Google more than Yahoo as a search engine. You get almost every information on Google where as Yahoo is not as update as Google. There are few more other reason on why Google is superior than Yahoo. Competion is likely more on Google rather than Yahoo. So Google can be more expensive than Yahoo.

i havent used yahoo before, so i cant tell the difference.

i think google is much more effective.

yes you are right it is more cheaper than google

As per my knowledge Yahoo is cheaper then Google, both are best search engine, but in this case yahoo is better then google. google quite expensive.

You will have more competitor on google as equated to yahoo. So yahoo will be decidedly cheaper.
