What is Bidding in Online Advertising?

Bidding in online advertising is the process of setting an amount that you are willing to pay for a click or a thousand impressions (CPM) on your ad.  

Through bidding process, advertisers compete for ad placements on digital platforms such as search engines, social media, and etc. When a user initiates a search, visits a webpage, or engages with digital content, ad space becomes available for advertisers to display their ads.

Based on where user initiated the journey (, YouTube or an publisher website), an ad in text, image or video format is served to user in the available ad slots; such as search engine result page (SERP), or a banner ad on a website.

How Bidding Works?

Bidding in digital advertising works through a real-time auction process, where advertisers compete for ad placements. The advertiser with the highest bid and the most relevant ad typically secures the ad placement.

The winner of the auction is determined based on several factors, including bid amount, ad quality, and relevance.

What type of auction is used by Google?

Google Ads uses a second-price auction system. It means what you pay is determined during the auction.

As the auction is dynamic, the actual cost per click (CPC) you pay is calculated in real-time.

This is also usually accepted and mostly used bidding type in which each bidder places a bid, the highest bidder gets the first slot and pays the price bid by the second highest bidder plus 0.01$.

You can see how much winner pays in the example below:

Google Ads Cpc

Ads Winner Pays Second-price auction system encourages advertisers to submit bids that reflect the actual value they place for the ad placement and provides an incentive for advertisers to create high-quality, relevant ads to users or prospects.


In Google Ads, there are several factors that can influence bidding:

  1. Budget (Your Bid)
  2. Targeting Parameters (Device, Location and etc.)
  3. Ad Quality (Ad Relevance & Landing Page Experience)
  4. Ad Format and Placement
  5. Time and Day of Week
  6. Competition

Based on all these factors, Google Ads decides which ads to serve and how much to charge for each click.

If you’ve understood what is bidding and how second-price auction works so far, we can now move to Google Ads’ automated bidding strategy and its benefits.

You can read more here about Google Ads bidding basics and Auction from Google’s articles.

In Google Ads, there are main 3 bidding strategies:

  • Smart Bidding
  • Manual Bidding
  • Automated Bidding

Google Ads Smart Bidding Strategy

It is a subset of automated bidding strategies that use Google’s artificial intelligence to optimize for the desired results in the auction.

This means that your bids will be adjusted by Google’s AI based on wide range of contextual signals and advanced machine learning to help you achieve your campaign goals.

You can tie this campaign goal to a business goal and select your Smart bidding strategy accordingly. You can refer to table from Google:

Business goal

Campaign goal

Smart Bidding strategy

Increase sales or leads

Get as many conversions as possible at a fixed budget or fixed ROI

Maximize conversions, Target CPA

Increase profit

Get as many conversions as possible at a fixed budget or fixed return on ad spend (ROAS)

Target ROAS, Maximize conversion value

Google Ads Manual Bidding Strategy

Manual bidding is when an advertiser sets the maximum amount that they’re willing to pay for each click on a keyword or an ad slot (display placement).

The main advantage of manual bidding strategies is that they give advertisers more control over their budget and allow them to adjust bids on specific keywords.

The downside is that manual bidding can be time-consuming and prone to human error. Plus, it might be difficult to keep track and stay on top of changes in the market fluctuations. So, you may be missing some great opportunities while keeping your bidding at a certain level.

That’s where automated bidding comes into play.

Google Ads Automated Bidding Strategy

Automated bidding strategies leverage Google’s machine learning to set bids for your ads. You don’t need to manually update bids for specific ad groups or keywords.

As its name suggests, automated bidding sets bids automatically based on the outcome you expect. Don’t worry, there are several automated bidding strategies which serve almost all your business needs.

Rather than manually setting bids, advertisers rely on Google’s algorithms and machine learning to adjust bids dynamically and Google (as expected) dynamically determines bid amounts based on the likelihood of your ad generating clicks or conversions.

We will repeat the phrase “algorithms and machine learning to adjust bids dynamically” throughout this content frequently, so hold tight! 😊
(PS: Not for on-page SEO purposes but for the sake of topic itself)

Why Automated Bidding Strategies?

I hear you asking…

The key benefit of adopting automated bidding strategies, is that it enables your campaigns to respond to changes like; user behavior, device, location, browser, competition, and other factors that influence ad performance.

The second most important benefit is for the Google Ads Experts: Google Ads automated bidding handles the manual work of adjusting CPC bids manually since Google Ads automatically adjust bids for you.

Let’s not forget about the fact that Google holds the most information about its users, so letting Google adjust bids according to fluctuations in market, is a good choice in most cases.

So, this strategy, basically, saves you tons of time and effort whilst keeping your bids competitive!

Target Impression Share

Target Impression Share bidding strategy is designed to help advertisers achieve a specific level of visibility for their ads on the search engine results page (SERP) or display network.

This strategy focuses on getting a set percentage of impression share which your ads receive compared to the total number impressions available for your keywords in any given auction.

Here’s an overview of its goal, use cases, and benefits:


Primary goal of this bidding strategy is to help you maintain a desired level of visibility for your ads. And of course, it comes with a cost. Costs of results is likely to be higher than your regular costs because you aim for a more favorable and a higher ad placement.

For instance, you can set your desired impression share, such as 70%, and Google Ads will automatically adjust bids to achieve that goal.

This means whenever your ads are eligible to be displayed, they’ll appear on top of SERP by 70% as often as your budget allows, and the remaining 30% will be displayed at the different sections on SERP.

Use Cases:

This strategy is suitable for mostly awareness objective, in competitive industries, or specific keywords where maintaining ad visibility is crucial.

Target Impression Share bidding strategy is designed for getting you a higher visibility on SERP and visibility of your ads rather than the number of clicks or conversions. If that’s suits your needs then, this bidding strategy is right one for you. 


You can use this strategy to ensure that your ads appear at the top of the page or at a specific section of the page. This enhances your brand visibility and increases the likelihood* of clicks.

*Note: Higher impression share doesn’t necessarily guarantee more clicks or conversions, so monitoring the performance of your campaigns and adjusting your targeting, ad messaging, and landing pages as needed is crucial. This strategy works well in combination with other bidding strategies to ensure a well-rounded campaign approach.

Target CPA

CPA stands for Cost per Acquisition or Action.

This bidding strategy is designed to help advertisers optimize their campaigns to achieve a specific “acquisition cost” goal by using Google’s machine learning algorithms. It adjusts bids based on historical data and real-time signals to achieve the desired CPA.


Target CPA bidding’s primary objective is to maximize conversion/acquisition at a given CPA. By using this strategy, marketers aim to deliver a desired volume of conversions within their budget.

Use Cases:

It is ideal if you’re looking to achieve a specific cost per conversion while generating a substantial number of conversions.

You need to set a realistic ROAS expectation from the campaign in order to get them running and served (getting impressions/clicks/conversions).

Pro Tip: You can of course expect a ROAS of 2, 3 or higher but if your ROAS isn’t realistic, this will provide enough liquidity for algorithm to go & bring the desired ROAS regardless.

Automated Bidding Strategies In Google Ads

How to Calculate ROAS

ROAS is calculated by dividing the revenue from your ad campaigns by the ad spend. The formula is as follows:

ROAS = (Revenue from Ad Campaigns) / (Ad Spend)

Let’s assume our revenue from this specific Google campaign is €1,600.

And we spent €900 for the campaign.

Our ROAS would be 1.600 ÷ 900 = 1.7

This means that for every euro we spent on the campaign, we generated €1.7 in revenue.


Target ROAS bidding’s primary objective is to generate as much conversion value as possible while maintaining the specified target ROAS.

Use Cases:

It is well-suited for advertisers who aims to generate revenue and profits from their ad campaigns rather than clicks or impressions. You can allocate your ad spend towards high-value conversions and maximize the return on investment.

It is particularly effective for e-commerce brands with varying product margins or different pricing tiers.

Besides e-commerce brands, there are relevant use cases for B2B SaaS companies as well.

B2B companies use this strategy to generate qualified leads for their software solutions to attract higher-value leads that are more likely to convert into paying customers.

Use Cases for Target ROAS in B2B SaaS Companies:

  • Lead Generation Campaigns
  • Trial Sign-ups and Demos
  • Subscription Acquisition
  • Event Registrations and Webinars
  • Upselling and Cross-Selling

If you know the lifetime value of a paying customer, you can set your campaigns to create positive ROI. However, you need to set, once again, realistic ROAS targets.


Automated Optimization: Automated process of this bidding strategy allows Google’s algorithm to uses historical data, machine learning, and real-time signals so that it can adjust bids dynamically.

Targeted ROAS Goals: In target ROAS bidding, campaigns focus on generating revenue and profitability. You can ensure that your advertising efforts generate a positive ROI.

Conversion Value Focus: The algorithm focuses to achieve the target ROAS and sets the bids based on historical data, user behavior, and contextual information.

Viewable CPM

For this strategy, let’s break down the term “Viewable CPM” itself into 2 and see what they mean: CPM and Viewable.

CPM stands for Cost-Per-Thousand Impressions. (An easy and common metric)

What is “viewable” then?

An impression is considered “viewable” when it meets specific criteria, which is hereby quoted directly from Google’s own article:

An ad is counted as "viewable" when 50 percent of your ad shows on screen for 1 second or longer for Display ads, or plays continuously for 2 seconds or longer for video ads.

Because you’re getting more valuable impressions, vCPM cost is likely to be higher compared to your average CPM in the very same or similar campaigns with different bidding strategy than Viewable CPM.


Viewable CPM bidding strategy’s primary goal is to ensure that your ads are displayed to your target audience users in a viewable manner as described by Google. This increases the likelihood of your ads’ visibility.
