Why Cost per Click Is Lower on Bing Than on Google
One of the strongest arguments for Microsoft Advertising is its lower cost per click. For the same keywords, you often pay significantly less per click than on Google. The main reason is simple: less competition. And from the same budget you get more clicks and, if you optimize correctly, more profit.
Why is cost per click lower on Bing?
Cost per click in an auction depends on how many advertisers compete for the same keywords. On Google, where almost everyone bids, competition is intense and pushes prices up. On Microsoft, far fewer advertisers bid, so there is less pressure on prices.
The main explanation is supply and demand. The result is that, for the same searches, clicks on Microsoft usually cost less.
Not because the traffic is lower quality - the search intent is the same - but because fewer advertisers are bidding on it. It is, in essence, a less crowded market, and the shortage of competitors translates directly into lower prices.
How does competition affect price?
In an ad auction, every click is put up for bid. The more advertisers willing to pay for a search, the more you need to pay to show up at the top. Competition is, in practice, the engine that inflates cost per click.
On Microsoft, with fewer competitors on the same keywords, the “auction” is more relaxed. You can get good positions at a lower cost, because you aren't fighting as many advertisers. That is the structural advantage of a network many people ignore: less competition means lower prices.
What does this mean for your budget?
The direct effect is efficiency. If each click costs less, the same budget buys more clicks. And if the traffic converts at a good rate, more clicks mean more conversions for the same money. In practice, Microsoft can stretch your budget further.
This matters most when costs on Google keep rising and hold you back. Instead of paying more and more for the same searches, you can move part of your budget to Microsoft and keep growing at a lower cost. Microsoft becomes a pressure valve for your budget.
Is it cheaper everywhere?
Not automatically, and not in every case. The cost gap varies by industry, by specific keywords and by how competitive your niche is on each platform. In some fields the gap is large, in others smaller; there are also niche situations where the two come close.
That is why the cost advantage should be verified for your specific situation, not assumed as a universal rule. An audit of the keywords relevant to your business shows where the real difference is and how much you can save by shifting part of your effort to Microsoft.
How do you take advantage of the lower cost per click?
The best way to benefit is to treat Microsoft as a complementary channel, not a replacement. You run Google for volume and add Microsoft for cheaper incremental reach. When costs on Google become prohibitive, Microsoft lets you keep scaling profitably.
A practical way to start is to import your campaigns from Google and then adapt them for Microsoft. You bring over a structure that is already validated and benefit from the lower costs right away, instead of building everything from scratch. The key is still adaptation: audience and competition differ, so the campaigns need to be adjusted too.
How do you keep the cost low through quality?
Low competition gives you a head start, but account quality amplifies it. A better Quality Score - earned through relevant ads, a tight structure and good pages - lowers the cost per click even further for the same position. In practice, you combine two advantages: a cheaper market and a well-managed account.
Cutting waste helps just as much. Negative keywords and shutting off weak placements make sure your already low budget goes only to the clicks that matter. A clean account on a low-cost network is one of the most efficient combinations in search advertising.
Low cost isn't everything: profit matters
A low cost per click is attractive, but it can become a trap if you look at it in isolation. Cheap clicks have no value if they don't turn into profitable sales. Likewise, a high ROAS from low-margin products can hide losses. Cost on its own doesn't tell you whether you are making a profit.
That is why the right measure remains profit - POAS (Profit on Ad Spend). Profit optimization accounts for the margin of each product and shows whether Microsoft's cost advantage actually turns into money earned. A low cost per click is an excellent start; profit is the destination.
