How to choose a Google Ads bidding strategy

Choosing the right Google Ads bidding strategy is one of the most important decisions you make when setting up a campaign. Your choice controls how Google spends your budget, which auctions it targets and ultimately what kind of results you get back.

There is no single best strategy. The right one depends on your campaign goal, your budget and how much conversion data you already have. Here is what each strategy does and when it works best.

## Manual CPC

Manual cost-per-click is the original bidding method. You set the maximum amount you are willing to pay for a click on each keyword or ad group, and Google tries to get you as many clicks as possible within your budget.

Use Manual CPC when you are launching a new campaign with no conversion history, when you need tight control over individual keyword bids, or when you are running a very small budget where every penny matters. The trade-off is time. You need to monitor performance and adjust bids yourself.

## Maximise Clicks

Maximise Clicks tells Google to spend your daily budget to get as many clicks as possible. It is a volume play and works well for awareness campaigns, new account testing or remarketing lists where you want to drive site traffic.

The risk is that clicks can come from low-relevance searches. Pair Maximise Clicks with solid negative keywords and watch your search terms report closely.

## Maximise Conversions

This strategy uses Google's machine learning to set bids that get you the most conversions within your daily budget. You do not set individual keyword bids. Google decides based on the likelihood of a conversion.

It needs conversion history, ideally at least 15 to 30 conversions in the past 30 days, to work well. If you switch it on with too little data, spending can spike with little to show for it. It is a strong choice once your account has a proven conversion baseline.

## Target CPA

Target cost-per-acquisition goes a step further. You tell Google the average cost you are willing to pay for a conversion, and Google aims to hit that target. If you set the target too low, spend will stall. If you set it too high, you will get conversions but at a higher cost than necessary.

A good starting point is your current average cost per conversion from the last four to six weeks. Target CPA works well for lead generation campaigns where you know what a lead is worth to your business.

## Target ROAS

Target return on ad spend is the most advanced automated strategy. You set a percentage return target, for example 400%, and Google bids to try to achieve it. It is best suited to ecommerce accounts with strong conversion data and consistent product margins (Home Instead saw +3,446% ad conversions through precisely this kind of optimised approach).

Target ROAS needs significant conversion history, at least 30 conversions in 30 days, and it works best across a well-structured campaign with clean conversion tracking. It is not suitable for most new or low-budget accounts.

## Enhanced CPC

Enhanced CPC (eCPC) is a hybrid. It starts from your Manual CPC bid and automatically adjusts it up or down (typically within a 30% band) when Google predicts a conversion is more likely. It is a good stepping stone from Manual CPC toward full automation while you build conversion data.

## How to choose the right one

Start simple. If you are new to Google Ads or have fewer than 15 conversions in the past 30 days, use Manual CPC or Maximise Clicks. Once you have a reliable conversion stream, move to Maximise Conversions. As your data grows, test Target CPA for lead gen or Target ROAS for ecommerce.
