Every second, there are billions of searches performed on Google, and the majority of search results pages include Google ads. Paid for by businesses, Google Ads is an effective way of driving relevant, qualified traffic to your website exactly when people are searching for the types of products or services your business offers.
In this article, you’ll learn what Google ads are, how Google ads work, and why you should run your own Google ads.

Google Ads is the name of Google’s pay-per-click (PPC) platform, which allows businesses to gain visibility across Google’s properties. The most common type of Google Ads ad is the search ad, which appears on the search engine results page (SERP) for searches relevant to the advertiser’s products and services—but businesses also use Google Ads to run display ads, shopping ads, YouTube ads, and more.
Below is an example of a Google SERP containing ads. There are two sections of paid results: one above the nonpaid or organic results, and one below.
As mentioned above, you can also run display campaigns which appear on the Google Display Network—an extensive collection of outside, third-party websites that have agreed to serve Google ads. Google Display ads can be in text, image, video, or rich media format, and can be targeted differently—such as through audiences and remarketing
Google shopping ads appear on both the regular SERP and in the shopping tab. These ads operate differently from regular search ads since you can’t target keywords. Instead, you maintain a detailed catalog of your products and Google will match them to searches. You can, however, tell Google which keywords you don’t want your ads to appear for.
Since Google owns it, YouTube advertising is done through Google Ads. You can create video, text, or display ads that appear during and before videos and elsewhere on the platform. YouTube ad targeting operates similarly to display targeting.
Google Ads is focused around keywords, the words that people are most likely to use when searching for their product. When advertisers create a Google Ads search campaign, they create ad with a specific offer and choose a list of keywords to target that are relevant to the offer. When someone searches on Google (also known as a query), Google will check to see if any advertisers are bidding on keywords relevant to that search. If there are, ads will appear on that SERP.
How does Google decide which ads to show? Enter: the Google Ads auction.
We explain, in full, how the Google Ads auction works here, but we’ll pare it down for a quick version. If, when someone searches on Google, advertisers are bidding on keywords relevant to the query, Google will enter all keywords into the auction that it deems relevant—one per account.
It will first give each keyword a Quality Score from 1-10, based on its relevance to the query and other factors. Then, it will give each keyword an Ad Rank score by multiplying its Quality Score by the corresponding advertiser’s maximum bid. The ads with the highest Ad Rank scores are the ones that show.
To “win” the Google Ads auctions and see your Google advertisement appear for relevant keywords, you’ll need to optimize your Quality Score and bid amount. The higher your Quality Score, in conjunction with your bid amount, the better your ad positioning. The following factors (among others) affect your Quality Score:
There are also overall benefits to having a high quality score:

In the US, the average cost per click for Google search ads across all industries is $2.32. In other countries, average costs for Google Ads are often much lower.
