Summary
Market share, bidding to value or volume with a break-even target CPA or ROAS, is the strategic goal to align with when a company wants to increase its footprint in an industry. A break-even target lets Smart Bidding win auctions that a profit-led target would decline, so volume grows without the account going into loss. Track Search impression share and Search lost IS (rank) to confirm the share is actually shifting.

A company that wants to grow its footprint in an industry should align its bid strategy toward market share, bidding to value or volume with a break-even target CPA or ROAS.
- Profit – Bidding to profit values with maximize conversion value/ROAS.
- Leads – Bidding to maximize conversions with the conversion action: lead form.
- Market share – Bidding to value or volume with a break-even target (CPA/ROAS).
- Revenue – Bidding to revenue values with maximize conversion value/ROAS.
The correct answer is: Market share – Bidding to value or volume with a break-even target (CPA/ROAS).
Key Takeaways
- – The correct answer is market share, achieved by bidding to value or volume with a break-even target CPA or ROAS.
- – Set the break-even target from gross margin and average order value, then apply it as Target CPA or Target ROAS in the campaign bidding settings.
- – Profit, revenue and leads goals all use tighter targets that limit volume, so they work against a share-growth objective.
- – Track Search impression share and Search lost IS (rank) after loosening the target, because a break-even target only helps if the extra spend actually converts into more auctions won.
How do I calculate a break-even target CPA for a market share push?
Take your average order value, multiply it by your gross margin percentage, and that is the maximum you can pay for a conversion before you start losing money. If AOV is 5,000 and margin is 30 percent, break-even CPA is 1,500. Feed that number into Target CPA rather than the lower profit-led figure you would normally use.
Which bidding strategies support a break-even target in Google Ads?
Maximize conversions with an optional Target CPA and Maximize conversion value with an optional Target ROAS both accept a target you set. You choose them in the campaign settings under Bidding, then enter the target value in the field that appears. Without a target, both strategies simply spend the full budget, which is a volume play but gives you no control over the price you pay.
Does chasing market share mean I should ignore profitability completely?
No. Break-even is the floor, not a licence to overspend. The point of a break-even target is that the growth pays for itself at zero contribution, so you fund share gains without draining cash. Once you have the share you wanted, you tighten the target back toward a profit level.
How do I know the market share strategy is working?
Add the Search impression share, Search lost IS (rank), Search lost IS (budget) and Search absolute top impression share columns to your campaign view. Rising impression share alongside falling lost IS (rank) tells you the looser target is winning auctions you previously lost. Also check the Auction insights report to see whether your overlap and outranking share against competitors is moving in your favour.
