Had adsense changed the coding?

I'm not sure if anyone will know but in the past when you used to set up adsense it was displayed like this:

<script type="text/javascript"><!--
google_ad_client = "PUB";
google_ad_width = 300;
google_ad_height = 250;
google_ad_format = "300x250_as";
google_ad_type = "text";

google_ad_channel = "ADSENSE CHANNEL";
google_color_border = "......";
google_color_bg = "......";
google_color_link = "......";
google_color_text = "......";
google_color_url = "......";
//-->
</script>

When I have looked into my stats because they were messing up I noticed a new layout, displayed like this:

<script type="text/javascript"><!--
google_ad_client = "PUB";

google_ad_slot = "*********";
google_ad_width = 300;
google_ad_height = 250;
//-->
</script>

Is that right? Also is the google ad slot the channel ID because I'm having some weird issues with my channels recently.

 

I don't think because that old codes working properly on my sites

 

I have a number of sites with adsense on and one of my older ones is working fine (old code) I did a change around with some of the channels and they began to mess up (new code).

 

Well IMHO both the type of formats work well.

 

Yeah, I have it working now. I think it was just an error when creating the ad block. I re-did it and integrated the new coding and it work fine so far.

 

"<script type="text/javascript"><!--
google_ad_client = "PUB";

google_ad_slot = "*********";
google_ad_width = 300;
google_ad_height = 250;
//-->
</script>"

This is the new code. You can edit these ads from your adsense account.
