Let's take a closer look at ad rank and quality score. What is a quality score? The factors that influence your quality score and how this quality score affects your campaigns.

Also, we'll explain the ad auction, what ad rank is, and how to improve your ad rank. And you'll see how important ad rank is in the process of maximizing exposure for your ads. So what is your quality score? A quality score is a metric used by Google to measure the relevance and quality of your ads, your keywords, and landing pages.

It's an important factor in determining the ad rank and the cost per click in the Google ad auction. So it's gonna determine the performance of your campaign because the higher the ad rank, the higher your click-through rate's gonna be, right? And remember, at the very beginning of this course, we talked about how the first three ads that appear on the page account for over 40% of the traffic. So ad rank is a very important determinant of your ad success.

And the more clicks you get, the more it will impact the cost per click in your Google Ads auctions. The higher the quality score, the more of these auctions you will win. The quality score is calculated on a scale from 1 to 10, with 10 being the highest.

Quality score is based on several factors, including the expected click-through rate. So, based on the quality of your ads and the keywords you're selecting, the Google algorithm is going to determine what this ad is likely to receive in terms of clicks, right? And it's also based on your brand's history, the relevance of the ad, right? That's why using the right keywords, the relevant keywords in your headlines and your description, is important because they all increase ad relevance. The landing page experience is also important.

Once you send, once a person clicks through your ad, where are you sending them? And is that page optimized for conversions? Is that page providing quality, useful information to your perspective, to your audience that's coming through? So all of those are factored in in determining this quality score. So, how does a quality score affect your campaign? It affects your ad rank, cost per click, ad position, and ad visibility, right? You know, how often it's gonna appear and where it's gonna appear. The ad extensions you can show are set up.

When you set up your ad, right? We saw how to do that. But Google would determine, okay, who gets to have, you know, be on that map, you know, that map. Who gets to showcase their products, right? So that depends upon your quality score and your keyword performance, right? So in any rate, the higher the quality score is gonna give you a better rank, a better position, and all that's going to improve the performance of your campaign, right? So you want to improve your quality score by focusing on relevant ad copy, targeted keywords, and optimized landing pages, and you can maximize the effectiveness of your campaigns.

And that in turn will maximize the return on investment of your advertising efforts, right? But first, let's look at the ad auction. The Google ad auctions are dynamic, complex processes that occur in real time whenever a user searches. So in that split second between you, you know, after you enter a search phrase or a query into the browser and press enter, in that split second before the results actually show up, this auction takes place, and all these things are happening in a very short period of time.

And these steps that happen, you know, sort of user searches, and then Google determines, Google's ad auction system identifies which ads are eligible to appear in response to that user search query. Ads are eligible based on factors such as keyword relevance, ad quality, targeted settings, and bidding strategy. So if that person fits the target audience you're bidding for but lives in Wisconsin while you are bidding for people in New York or Pennsylvania, they're not eligible.

They may meet all the other eligibility requirements. They may have used the keyword that you are, you know, that you are bidding on, but they don't meet all the requirements of the audience, right? If they are typing a keyword you haven't bid on, they're not gonna be shown your ad either. So that's the first thing: after the user searches, the ad eligibility determination.

Then the ad rank calculation, right? And we're going to go into the specifics of this calculation, but for now, understand that for each eligible ad, Google calculates an ad rank that determines the ad's position on the search results page. So all these ads fit the requirement for keyword and audience, but now the ad rank is gonna say, well, this ad's gonna appear first, this ad's gonna appear second, this ad's gonna be on the next page, that type of thing. Ads with ad positioning and the highest ad ranks are placed in the most prominent positions on a search results page, typically at the top of the page or in the sidebar, right? Sometimes you see ads along the side of the search.

Lower-ranking ads may appear lower down the page or on a subsequent page. You might not even get on the first page. That's definitely gonna impact your click-through rates.

It's definitely gonna impact your conversions because fewer people are gonna see you on the second page, meaning fewer people are gonna click through your ad, get to your landing page, and convert. Then the actual ad auction process. The ad auction process is conducted in real time for each individual search query.

Google's ad auction system evaluates all eligible ads and determines their positions on a search page based on their ad ranks. And then ad placement: when they win the auction and are displayed on a search engine result page, top-ranking ads appear in the most visible positions. The order of ads is based on their ad ranks, with higher-ranking ads appearing higher on the page. So all of this is taking place during that auction, right? Cost calculation.

Advertisers are charged based on a pay-per-click model, meaning they only pay when users click on the ads. So that was one of Google's great innovations: saying, "Look, you show up in the search results." If they don't click on you, you're not paying for that, only if they click on you, right? Right, so your budget determines how much you're willing to pay.

And then when people actually click on you, then that's when the budget starts to be depleted, right? So let's drill down on ad rank. What is Google Ad Rank? Google ad rank determines the position of ads on the SERP and the Google Display Network. Ad rank is calculated based on the bid amount, right? The maximum dollars that an advertiser's willing to pay for a click on their ad.

That could be by cost per click when you set up your campaign. Also, when we were clicking on a search ad, if you were trying to run a campaign, it was a display ad campaign, where you are showing ads to people on various websites on the Google Display Network. Well, then you might also set a bid based upon the cost per impression, the number of times that the ad is seen.

And the metric to determine the cost per impression is cost per thousand, meaning how much are you paying for a thousand impressions? So a $10 cost per thousand means that to get your ad seen by a thousand people, it's going to cost you $10. If you want it to be seen by 2,000 people, it's gonna cost you $20. If you want it to be seen by 10,000 people, it's gonna cost you $100, right? So that's cost per thousand.

All right, once you set your bid amount, a quality score measures the relevance and quality of the ad keywords and landing pages. So, essentially, there is an equation: ad rights equals quality score times bid amount. So the better your ad is, the better, the more relevant it is, the more relevant your keywords are, the more appealing that Google determines it to be, the more effective Google determines your landing page to be, that's a higher quality score.

Then there's the bid amount. So the higher the bid amount, well, obviously, the more auctions you're gonna win. If you're willing to pay $10 per click and your competitors are willing to pay $ 7, you're gonna win more auctions, right? But the beauty of the quality score is that if you have a higher quality score, you might win auctions against competitors that are paying more, but essentially, the quality score is going to overcome some of that gap between what they're willing to pay and what you're willing to pay.

So, obviously, we can spend more, but what you can control is the budget might be out of your hands, but if you can get more, a higher quality score, you can get more auction wins out of the same budget as someone else, right? But your quality score is higher. So that leads us to the question: how to improve your ad rank? Well, if you wanna optimize your quality score, use keyword research to improve your ad headline and ad copy, and make sure whatever you describe in your description or address in your headlines is relevant to your target audience. It addresses their pain points, their needs, et cetera.

You also wanna test and improve your landing page experience. In section seven, we'll be discussing landing pages. And you wanna test ad copy, headlines, take the suggestion from Google Ads when it's telling you, you know, here's a suggested headline, use this headline. We think it'll increase your performance by X percent.

You saw some of those tips, but between you looking at your results and taking in insight from the platform, you wanna continue to try and optimize your qualities, you know, the effectiveness of your ad copy and headlines to improve your quality score. You can also adapt the gesture bidding strategy, which is the other part of the ad rank equation. To that end, increase the maximum bid amount for high-performance keywords and ads.

You're saying, look, I have, you know, for these particular keywords, which are so important, I'm gonna increase the bid on those. Maybe going into the holiday season might increase the bid on Black Friday, you know, there's gonna be a lot of competition, but I wanna win some of those competitions, you know, so I will increase it during that time period. Monitor competitors' bidding activity and adjust accordingly, right? And we can, I'll show you where you can do that on some of these platforms a little bit later.

Use bid modifiers to tailor bids to specific audience segments, so you can, it's a little bit more complicated, we're not really gonna get into that as much here, but you can, you know, as you set up your campaigns, you can say, look, for these particular audience segments, for these ad groups, I want to spend more, right? And you wanna leverage ad extensions, experiment with different ad extensions to see which ones resonate best with your audience, and drive better results. You wanna add an ample amount of ad extensions, seeing if there's additional ones you can include, additional pages that you can send people to, additional features and benefits that are likely to cause a reaction from the audience, see how the existing ones are doing, and, you know, basically adjust accordingly.
