4. Modify the Widget code
Modify the code as shown below by adding the “if” condition (in bold). Make sure you add the “if” condition just after the <b:includable id='main' section> and the closing “if” code just before the </b:includable>.
<b:widget id='AdSense1' locked='false' title='' type='AdSense'>
<b:includable id='main'>
<b:if cond='data:blog.homepageUrl != data:blog.url'>
<div class='widget-content'>
<data:adCode/>
</div>
</b:if>
</b:includable>
</b:widget>
