5. Do you guarantee to have relevant ads for my site?
Since the ability for us to serve ads on your site depends on a number of factors, such as our ability to crawl your site, the content of each of your web pages, and the availability of related Google ads, Google does not guarantee that we'll always have relevant ads to display. If we don't have relevant ads for a given page, or if we haven't yet crawled your site, we may display public service ads or your specified Alternate Ads, for which you will not accrue any AdSense earnings.
Similarly, if Google does not have ads for a search query, or if the query will return non-family-safe advertisements, we will not show ads.
