# Why a zone shows nothing yet > A live zone that never shows our ad: who we buy today, how targeting and your floor decide, frequency limits, and how passback keeps the spot earning.

Not serving always comes with a reason: paused by you, paused by our team, site not verified, site under review, site paused, or closed to the market. Live means nothing on our side stops the zone from being sold. It does not promise that every visitor is bought. Also check that the tag is detected. If it still says Waiting for the first call, see [Create a zone and install the tag](https://lananetwork.com/guide/create-a-zone-and-install-the-tag). ## Who we buy today Today, buyers purchase impressions from mobile visitors whose browser is in English or Spanish. Everything else goes to your passback. Our tag asks for an ad only for these visitors; everyone else goes straight to your passback, without waiting. Automated and data-center traffic is passed back too. Then each advertiser campaign picks its own countries, devices, operating systems, languages, browsers and hours. A visitor that no live campaign targets gets your passback. Today most demand is for visitors in the United States, so a site with little US mobile traffic will see a low fill. ## Your floor and the format - Net floor: a bid only wins your zone if what it would pay you reaches your net floor. A floor far above the market means passback for most visitors. Lower it in the zone settings to test. - Format: a banner, slider, interstitial or in-page zone needs a campaign with an approved image of that size. A popunder zone needs a campaign that buys popunder. Some formats have no buyer today: the format list, the zone wizard and the Formats page show a No buyers today badge on them, and zones of that format go to your passback until a buyer arrives. - Frequency limits: a visitor sees at most one ad per zone per cap window, 24 hours by default. Interstitial zones show once per visitor per 24 hours and in-page zones once per 6 hours, whatever the zone says. Testing from the same phone, you will see an ad once, then the passback. ## Your floor and what it costs When a bid is under your net floor, the visitor goes to your passback and the zone shows a refused decision. Sites & zones and Reports show What your floor cost you: refused decisions, average refused bid (net CPM), your floor now and earnings you may have missed, over 7 days. It is an estimate from a sample of refused decisions over the last 7 days. A refused decision is not a guaranteed impression: a lower floor does not create bids that do not exist. - Suggested floor: next to the floor field, Suggested shows the 40th percentile of the net bids refused on your zone over the last 7 days (with enough data), otherwise the public floor of the format, converted to net. It is never under the network floor. Use suggested copies it into the field; press Save to apply. - A floor per region: Set a different floor per region opens three fields, United States, Canada, Australia and New Zealand, and the rest of the world. Defaults are 60 % and 30 % of your US floor, and you can change them. Unknown countries use the rest of the world floor. - Why regions: buyers today purchase mostly US mobile traffic; other regions mostly go to your passback. A lower floor outside the US only helps if a buyer targets those visitors. - Net eCPM by country: in Reports, break down by country, highest first. ## What passback means for you When we do not buy, your passback runs, so the spot keeps earning with your usual network. Interstitial and in-page zones have no passback: when we do not buy, nothing appears at all, which is expected. ## Read your numbers 1. Open Reports and pick the last 7 days. 2. Break down by zone and read the Fill column: the share of the visitors the tag asked about that we bought. 3. Break down by country or device to see where your traffic is. Fill is only computed by day, hour, site, zone and format, not by browser, OS or sub-ID. A fill of zero on a zone with traffic usually means your visitors are outside what campaigns target, or your floor is above the bids. ## If something goes wrong If the zone is live, the tag is detected, your floor is at the public minimum and you still see no fill after a few days of mobile traffic, contact support with the zone name: we can tell you which rule sends your visitors to passback. ## Frequently asked questions ### Does an empty zone cost me anything? No. A visitor we do not buy gets your passback, so your usual network keeps earning on that spot. ### Why do I see the ad once and never again? The frequency limit: one ad per visitor per zone per window, 24 hours by default. Use another phone or wait for the window to test again. ### Do you buy desktop traffic? Not today. Our tag only asks for an ad for mobile visitors; desktop visitors get your passback straight away. ### Will a lower floor always raise my fill? No. A lower floor only helps when there are bids under your current floor: it does not create bids that do not exist.
