What to consider before you click on your own link units
AdSense publishers are permitted to click on link unit topics on their webpages, provided that they do not click on any Google ads on the resulting page. Clicking on the ads themselves is prohibited, as it has the potential to inflate advertiser costs.
However, you may still prefer not to click on the link unit topics that appear on your site, as clicking on these links has the potential to inaccurately inflate impressions and affect your reporting metrics.
