# How USA PPC Teams Should Use Device Bid Adjustments

Not every click is worth the same price, and the device it comes from is one of the clearest reasons why. A USA service business may find that mobile searches produce most of its calls, while desktop searches produce most of its form fills — yet both are bought at the same bid, which means one device is overpaid and the other underfunded.

Start by splitting performance by device. Compare conversion rate and cost per lead for mobile, desktop and tablet separately over at least a month, so a single busy week cannot distort the picture. Where mobile converts well but wins too few auctions, a positive bid adjustment puts the ads in front of more of those searchers; where tablet traffic clicks but never converts, a negative adjustment stops paying full price for it.

Then match the landing experience to the device. Mobile visitors need a tap-to-call button and a short form, while desktop visitors tolerate a longer page with more detail. Sending both to the same page and blaming the bid is a common mistake; the bid adjustment only works when the page fits the device.

Finally, revisit device settings monthly. New phones, seasonal travel and changing customer habits shift the balance over time, so a setting that was right in spring may be wrong by autumn. Teams that review device reports alongside search terms, often with help from ppc campaign management specialists, pay each device what it is actually worth.
