<report>       <report-name name="criteria performance report #559f659c928ac"/><date-range date="jul 3, 2015-jul 9, 2015"/>       <table>         <columns>           <column name="clicks" display="clicks"/>           <column name="keywordid" display="keyword id"/>           <column name="totalconvvalue" display="total conv. value"/></columns> </table> </report> 

if use google adsense preview tool not showing adds here. doing wrong or possibilities test account?

a test account doesn't accumulate impressions (as ads not being shown), you'll need set

$reportdefinition->includezeroimpressions = true;
