google ads – where to put the code (again)

I’m trying to put Google ads on my site. I have searched the forum on this but can’t find quite the answer I need.

I’ve put the ad code just before the last div on the index.php page so the end of the page reads

`<p><?php _e(‘Sorry, no posts matched your criteria.’); ?></p>
<?php endif; ?>
<p align=”center”><?php posts_nav_link() ?></p>
<script type=”text/javascript”><!–
google_ad_client = “pub-7466261488630531”;
google_ad_width = 234;
google_ad_height = 60;
google_ad_format = “234x60_as”;
google_ad_type = “text_image”;
google_ad_channel = “”;
google_color_border = “EBDCC6”;
google_color_bg = “FFFFFF”;
google_color_link = “f0f0f0”;
google_color_text = “000000”;
google_color_url = “8a3207”;
//–>
</script>
<script type=”text/javascript”
src=”https://pagead2.googlesyndication.com/pagead/show_ads.js”&gt;
</script>
</div>
<?php get_sidebar() ;?>
<?php get_footer(); ?>`

The ads did show up briefly last night but, never content, I tried putting them on some other pages as well. The ads disappeared. I removed the code from the other pages so it is just on index.php but the ads have not come back.

My question: do I just need to wait for Google to check that my code is correct again or do I have it in the wrong place in the index.php file?
