What does FILL RATE refer to?
Fill Rate refers to the rate at which we were successfully able to serve ads on a given website. This is also sometimes called Sell Through Rate.
Why don't ads always show up on my site?
Ad Networks like G&R must constantly balance relationships with Publisher websites and Advertisers. If not enough people want to advertise, the fill rate will be less than 100%. Sometimes advertisers only want to reach certain audiences - for example, only people visiting a website from the UK. If this happens, your site will have a 100% fill rate for people visiting from the UK but not necessarily for people visiting the site from anywhere else.
What is G&R doing to make my fill rate 100%?
G&R works hard everyday to sign on more advertisers. We also making deals with international ad networks to serve "backfill ads" when our ad inventory is low.
