Bidding Strategies

Target Impression Share vs Manual Bidding: Who Chases Position

In short: Manual bidding fixes a price and accepts whatever position it earns. Target Impression Share fixes the position and share of impressions and raises bids up to a ceiling you set to hold it. Neither reads conversion data, so the choice is about whether you want to automate the chase for prominence.

Manual Bidding

Setting bid amounts yourself rather than delegating them to the platform, adjusting by keyword, ad group, or placement on your own schedule.

You control the number and the platform controls nothing beyond the auction itself. That gives clean cause and effect for testing, works on accounts with too few conversions for automation to learn from, and keeps spend predictable. As accounts grow, the ceiling shows: you cannot adjust per auction. The mistake is equating manual with cheaper, when in practice it mostly means slower to react.

Target Impression Share

Sets bids to reach a chosen share of impressions at a chosen page position, bounded by a maximum CPC ceiling you define.

You pick absolute top, top, or anywhere on the results page plus a percentage, and Google bids whatever is needed up to your ceiling. It is a visibility strategy, used mostly for brand defense and specific competitive terms where presence matters more than efficiency. The mistake is running it on non-brand terms with a high ceiling, since it buys position whether or not those impressions ever convert.

Side by side.

The differences that actually change what happens in your account.

	Manual Bidding	Target Impression Share
What you name	A maximum price per click.	A page position and a percentage of eligible impressions.
What varies	Position, with the price held.	Price, with the position goal held.
Cost control	The bid itself.	A separate max CPC ceiling, the only lever available.
Conversion data	Not used.	Not used.
Maintenance	Raising bids by hand each time you slip.	Automatic within the ceiling you set.
Right home	Small sets where each term's worth is known.	Brand defense and a short list of must-win terms.

What actually separates them.

Manual bidding will lose the slot rather than exceed your number; a position target will pay whatever the slot costs up to the ceiling, which is a different risk profile entirely.

The ceiling on a position target is doing the job your bid used to do, which is why leaving it generous behaves like an open budget on competitive terms.

Manual bidding can price each term individually, whereas a position goal applies across the campaign and pursues prominence on your weakest terms too.

Neither strategy learns, so improvement under both comes from your work on keywords, negatives, ad quality, and ceilings rather than from the bidder.

Impression share is reportable under manual bidding, so wanting visibility data is never a reason to switch strategies.

Which one should you use?

Use Manual Bidding when

Position is not the objective and predictable spend matters more.
Each keyword has a different worth you want expressed in its price.
Budgets are small enough that paying for the top slot would consume the day.
A test window where a fixed price keeps results readable.

Use Target Impression Share when

A competitor is bidding on your brand name and you keep manually raising bids to respond.
A short list of high stakes terms where being missing loses the deal.
A launch window where share of voice is genuinely the objective.
You have set a deliberate ceiling and will review spend while it runs.

Common questions.

Is a position target just automated bid raising?

Functionally close, with one difference that matters: it raises until the goal is met or the ceiling is hit, without any regard for what a click is worth. Manual bidding never exceeds your number. If you want a ceiling plus judgment about which auctions deserve it, neither option provides that, and conversion based bidding does.

What impression share percentage should I aim for?

Choose it from what absence costs rather than from a round number. Chasing very high share on any term means paying for the auctions you were losing for a reason, which are typically the least valuable ones. On brand defense a high share is defensible; elsewhere, moderate share with a firm ceiling usually spends better.

Which handles a competitor entering my brand terms better?

A position target, provided the ceiling is set deliberately. Manual bidding responds only when someone notices the slip and edits, which can take days. The trade is that the automated response has no idea whether the competitive pressure is worth matching, so the ceiling is the only place your judgment enters.

Or stop choosing between them.
