A crawler, also known as a spider or a bot, is the software Streaming platform uses to process and index the content of webpages. The AdSense crawler visits your site to determine its content in order to provide relevant ads.
The crawl is performed automatically and the crawler report is updated weekly.
This is how the channel page looks like, before the AdSense banner is inserted:
If the AdSense crawler hasn’t ever visited your site, it may take up to 48 hours or more before the crawler visits and gathers content from that page. In the meantime, you may see that ads are displayed as transparent boxes or contain any alternative ad or color specified in the ad code or ads that are only slightly relevant.
Please wait a few days after your AdSense code is published for the ads to start showing up.
This is an example of an AdSense banner displayed on the channel page:
Note: when you are copying the AdSense code please pay attention it does not have extra comments.
Example: [ /* Comment – Right Bottom Front */ ].
Please check the AdSense Code you are trying to embed in the channel page, and strip any comments.
Example of Google AdSense code:
google_ad_client = “pub-2151667935419035”;
/* 468×60, created 7/17/08 */
google_ad_slot = “7112975069”;
google_ad_width = 468;
google_ad_height = 60;
