How The Ad Auction Works

PPC Guide: How the ad auction works & Best ROI

Ad bidding is the process through which ads are placed on search engine results pages (SERP) to generate ad revenue. It is a competitive process where advertisers bid against each other for ad space on the search engine results page. The ads that are clicked are usually the most relevant to the user.

To make the ad bidding process as efficient as possible, Google looks at several factors when calculating the quality score, one of which is ad rank.

Ad rank is determined by relevance, quality score, and position. relevance is determined by the keyword level match between the ad and the keyword(s) being targeted, quality score is determined by landing page quality and click-through rate (CTR), and position is determined by the bid price and position in the SERP.

Advertisers can also adjust their bids according to keyword bid quality score (KBS) and campaign budget. KBS measures how well ads are performing relative to their expected performance based on historical results of ads with similar keywords. The campaign budget determines how much an advertiser is willing to pay for ad space on the search engine results page.

In addition to ad rank and keyword bid quality score, Google considers other factors when bidding for ads including CPC (cost per click), CPM (Cost Per Thousand), ad group positions, ad relevance, and daily budget limits.

CPC calculates what an advertiser will be charged for every ad click while CPM estimates how much an advertiser will be charged per 1,000 impressions served.

Lastly, ad groups in Google Ads determine how many ads can be placed on one page and how they are displayed. Ad groups work similarly to campaigns in that they allow an advertiser to.

What is Quality Score?

Quality score is an indicator of how relevant an experience is to users and affects the position of ads in search results.

  • Quality score is rated on a scale of 1 (bad) to 10 (excellent). The higher the quality score, the higher the relevance and quality of the ad.
  • A high-quality score can lower cost-per-click (CPC), and/or improve the average position. Improving your quality scores can help you reach your target audience more effectively and save money.
  • Quality scores cannot be visible to advertisers, but Google does provide a rating. This rating gives advertisers an indication of how relevant their ads are to users and helps them make informed decisions regarding their ad campaigns.
  • Having a high-quality score is an important metric for successful PPC campaigns as it provides a measure of how well your ads are targeting your target audience and aids in making informed decisions regarding keyword bidding, ad copy, landing page, campaign budgeting, etc.

Google looks at three things when calculating Quality Score:

When calculating the Quality score in Google Ads, the keyword-level quality score takes into account landing page experience, expected click-through rate (CTR), the relevance of the ad to the query, and the relevance of the ad group to the keyword. In addition to these keyword-level quality score parameters,

Google also looks at landing page experience, expected CTR for an ad group, and relevance of the ad group to the keyword. These factors are used to rank keyword-level quality scores from 1 to 10.

Besides the keyword-level quality score, landing page experience is also considered when calculating the quality score at the keyword level. Indexing a landing page that provides a good user experience is one of the main criteria for a keyword’s quality score.

So, ads with relevant landing pages will have higher quality scores compared to ads with irrelevant landing pages. Furthermore, search ads that directly correlate with queries have higher quality scores compared to search ads that don’t directly correlate.

How does Google weigh each Quality Score factor?

Quality Score is the assessment of keyword relevance and quality performed by Google. Quality Score considers keyword relevance and quality, with a rating from 1-10. It considers landing page experience, expected click-through rate, and relevance to the query when calculating Quality Score.

Landing page experience measures the landing page’s relevance to the ad and if it provides a good user experience. The expected click-through rate measures the estimated number of times an ad will be clicked on.

This score takes into account all three factors that Google considers when calculating Quality Score.

What is Ad Rank?

Ad rank is a metric used in the auction process of pay-per-click ads (PPCs) to determine the positions if ads on search engine results from pages. Ad rank takes into account ad quality score, maximum cost-per-click (CPC), and the expected click-through rate of ad extensions and formats.

The ad rank is calculated using the formula: ad rank = ad quality score x max CPC + a combination of other factors, including the context of the search such as device and expected impact of ad extensions.

Ad rank helps advertisers make an informed decision regarding their bidding strategy by providing a relative measure of ad performance.

It helps them understand which ads are performing well and which aren’t. Additionally, it can help them adjust their bidding strategies accordingly and ensure they are getting the most value for their advertisement spend.

How does Google Ads bidding work?

In the bidding system of Google ads, advertisers can choose from different bidding strategies to optimize their campaigns. Each bidding strategy is based on the objective of the campaign, such as optimizing for clicks, impressions, or video views. The bidding strategies also take into account other factors at the time of the auction such as ad quality score.

The ad auction bidding process works as follows: When creating a Google ads campaign, you must choose a bidding strategy for your ads. This will determine your ad rank and bid. Your ad rank is determined by your auction-time quality score and bid.

The higher your ad rank, the cheaper your cost per click will be. In an ad auction, your bid becomes an important factor in determining your ad rank and cost per click.

The bidding strategies also vary based on the type of keyword being bid on.  For example, keyword bidding strategies are used for keywords that have high search volume but low relevance. Different keyword bidding strategies can help improve campaign performance.

What Factors Influence the Google Ads Auction?

The Google Ads auction takes into account several factors when determining which ads appear. These include your ad’s bid, the quality of the ads, the landing page experience, and the context of the person’s search. Each of these factors influences bidding strategies, which can be optimized for different goals such as conversion value, conversions, clicks, impressions, video views, or engagement.

Your bid amount is the maximum you are willing to pay for a click on your ad. It is important to determine your bid your budget and desired performance metric.

Your Quality Score is an assessment of the quality of your ad and is one of the factors used in the auction. A high-quality ad with a high-quality score could result in a higher bidding price than an inferior ad with a higher Quality Score. However, a low-quality ad with a high-Quality Score could also result in bidding below average.

How is CPC calculated?

CPC stands for Cost Per Click, the amount paid by advertisers to search engine partners for every user clicks on their advertisement. That’s the cost of acquiring a user’s attention and conversion to a sale.

  • The term is used in pay-per-click ad campaigns such as keyword ads, where the advertiser pays when the user clicks on the ad. It’s also used in cost-per-action ads, where the advertiser pays for each action taken by the user after seeing the ad.
  • A keyword ad campaign uses keywords to target users with specific interests. In a keyword ad campaign, people bid on ad positions based on how much they are willing to pay per click. This is known as keyword bidding.
  • The maximum CPC is the bid that an advertiser submits to be entered into the PPC auction. This is typically higher than the actual cost of bidding because it takes into account competition and other factors.
  • The quality score is determined by several factors such as keyword bidding quality, landing page quality, landing page relevance, landing page usability, search query quality, and copy quality.

The higher the quality score, the lower the cost per click will be.

  • An advertiser’s ad rank is calculated using factors such as landing page quality and keyword bidding quality. When comparing ad positions between different advertisers, search engine partners may use this value to determine which ad should be displayed on a page or given more visibility in search results.
  • The actual cost of bidding at an auction is calculated based on bids from other advertisers and how many impressions their ads are shown for. When bidding for and position at an auction, it’s important to consider.

How much does Google Ads cost?

Generally, keyword bidding is used to determine the bid price of an ad. The higher the keyword search demand, the higher the bid price. This bid price is then multiplied by the cost-per-click rate to get a number that represents how much it will cost to show an ad on a keyword search engine like Google or Bing.

Google Ads can be a great way to get your business noticed online, but it’s not free. The average cost per click for Google Ads is between $1 and $2 on the Google Search Network. Depending on the industry you’re in, the cost can vary—for example, auto ads can be as low as $0.58, while B2B ads can be as high as $3.33.

For mid-sized companies and agencies, the cost usually falls between $7,000 and $30,000 per month. You’re in control of your budget—you set the cap each month and you can stop at any time. Google Ads may come with a price tag, but the potential benefits of getting your business noticed online are priceless!

How many times does a Google auction run?

In the ad auction, ads are shown based on a bidding process. The bidding process decides who’s going to pay for the ad space. The higher the bid, the higher position on the page or in the ad appears.

  • Google ads run a lightning-fast auction every time someone searches on Google or visits a site that shows ads. This bidding process determines which ads appear for search queries and what quality of ads will appear.
  • The auction is based on five factors: bid, quality of the relevance to the keyword, and landing page quality score. These factors go into an algorithm that determines which ads are eligible to show for a search query and how much they’ll pay.

The bidding process lasts a fraction of a second and is repeated every time an ad is eligible to appear for a search query. That’s why you may see ads for the same keyword several times in one session of bidding.

  • There are two types of auctions: fast and slow. A fast auction results in an immediate price set by the advertiser and a fixed-duration auction results in multiple offers with a fixed duration. The number of bids made determines the winner of the auction.
  • You can control ad rotation with your bid in both types of auctions but it won’t make much difference except if you’re targeting specific keywords that often appear on the page you’re bidding on.

How does the Google auction work?

What is the average cost per click for Google Ads?

‘’Cost per click’’ (CPC) refers to the amount an advertiser pays each time a user clicks on their ad. The cost is determined by the keyword bid and quality score, plus the bidding increment. For example, if an advertiser uses a keyword with a bidding price of $2 and a quality score of 30, the cost per click would be $2.69.

The keyword bid is the maximum amount an advertiser is willing to pay for a keyword ad. The bidding increment is the difference between a keyword’s bid price and the cost per click. The quality score measures how relevant an ad is to a user’s search query.

The actual cost per click (also known as “CPC) is determined based on the maximum bid, quality score, and keyword competitiveness. For example, if the max bid for a keyword is $1 and its quality score is 15, the CPC would be $0.63. This cCPCpricing depends on factors such as keyword competition and bidding budget.

What is CPM bidding?

  • CPM bidding is a manual bidding strategy used for PPC ads that allow advertisers to set the highest amount they want to pay for eevery1,000 impression of their ad. The cost-per-mille (CPM) bid allows advertisers to control how much they are willing to pay per 1,000 impressions of their ad.
  • With CPM bidding, advertisers can choose a maximum bid that they are willing to pay for each ad click and adjust it as necessary based on the advertiser’s target cost per acquisition metric.
  • For example, an advertiser could decide to target an audience with an ad and set a maximum bid of $10. If the ads generated 3 clicks, the advertiser could expect to pay $3 per click. If ads generated 25 clicks, however, the advertiser could expect to pay $1 per click.
  • CPM bidding is used in auctions to determine whether ads will show on search engine results pages (SERPs) and in what order. For example, if an advertiser bids $5 for 1,000 ad impressions and another advertiser bids $4 for those same ad impressions, the ads may or may not be shown at the top of the search results page based on various factors such as the quality of the ad copy and landing page experience.
  • Depending on your targeting strategy, CPM bidding can provide valuable insight into your campaign’s performance and help you make adjustments as needed.


– Cost-per-click (CPC) and cost-per-thousand-impressions (CPM) are two commonly used advertising formats in digital media.

– CPCs are the cost of an advertisement based on the number of clicks it receives, whereas CPMs are the cost for an advertisement based on the number of impressions it takes.

– When comparing the two formats, there are a few things to consider. One is that CPC typically ranges from $0.02 to $3.00 per click, while CPMs vary from $0.01 to $10.00 per thousand impressions. Additionally, ads with CPCs tend to have higher ad relevance than ads with CPMs due to the price of ads being based on the number of clicks they receive, while ads with CPMs tend to have higher bidding due to the price per thousand impressions.

– When using both formats in tandem, ad relevance is maintained by ensuring relevant ads pay higher rates than non-relevant ads, making for better ad quality and visibility for all parties involved.

What is an ad group in Google Ads? How do ad groups work?

An ad group is a container for your Google Ads keyword, landing page, and ads. This way, you can group your ads by keyword and landing page to create themes for your campaign. This makes it easier for you to target your ads to specific demographics and audiences.

You may find it helpful to organize your keywords into ad groups based on the type of audience you’re targeting. For example, you could use keyword ad groups for keywords related to particular products or categories, such as ‘candy,’ ‘cooking devices,’ and ‘women.’ You could also use ad groups for keywords related to a particular topic or interest, such as ‘travel’ or ‘auto.’

Using keyword ad groups helps you target ads to relevant audiences based on their interests. However, it’s important not to dump all your keywords into the same ad group. Instead, consider organizing them into themes so that your ads are relevant and concise.

Google tends to reward advertisers who create well-structured ad groups with high-quality scores. Thus, you must create ad groups that are relevant and engaging for your audience.

What is ad relevance in Google Ads?

Ad relevance is a metric used to improve the quality of ads shown on the search results page of Google, Bing, and other search engines. It’s a measure of how relevant the keyword being bid on is to the advertisement and landing page. This helps improve click-through rates and Quality Scores in Google Ads. Ad relevance also helps ads be relevant to search queries and content on a landing page.

Ads are typically text or image-based. With the help of artificial intelligence, ad relevance can help ads match landing page content, keywords, and user intent. Social ads are used to promote products and services on social media platforms. They are also used to target specific demographics in the audience via custom audiences or ad group targeting.

How to improve your PPC bidding skills

There are several bid strategies you can implement to optimize the performance of your PPC ads. One of the most popular strategies is bidding on keywords with the highest cost-per-click (CPC) and bidding as high as possible. This is a great way to target the keywords with the highest potential ad revenue, but it can result in spending more money than you intend.

Instead, consider manually setting bids for each keyword based on your analysis of the keyword’s cost-per-click and ad popularity. This will help you stay within budget while targeting the keywords with the greatest potential for ad revenue.

Another strategy is to use automated bidding strategies such as Enhanced CPC and Target CPA. These strategies can help adjust bids for more efficient spending, which helps to maximize ad revenue without sacrificing quality or targeting.

Overall, it’s important to monitor campaigns regularly and adjust bids accordingly to ensure you’re meeting your goals and ad quality remains high.
