Google Ads, formerly known as Google AdWords, is an online advertising platform developed by Google. It allows businesses and advertisers to create and display ads on Google’s search engine results pages (SERPs), as well as on the Google Display Network, which includes various websites, mobile apps, and other online platforms where Google ads can appear. Google Ads is a popular and effective way for businesses to reach potential customers and drive targeted traffic to their websites or landing pages.

Here’s how the Google Ads auction works:

  1. Advertisers Create Campaigns: Advertisers start by creating advertising campaigns in their Google Ads accounts. Within each campaign, they can create ad groups, which contain sets of related keywords and ads.
  2. Keyword Selection: Advertisers choose relevant keywords and keyword phrases that they want their ads to appear for when users perform Google searches. These keywords should be aligned with their business or products.
  3. Bid Strategy: Advertisers set a bid strategy for their keywords. They specify how much they are willing to pay for each click on their ads or for other campaign objectives like impressions or conversions.
  4. Ad Auction: When a user enters a search query on Google, Google conducts an ad auction to determine which ads will be displayed in the search results. This process happens in real-time for each search query.
    • Keyword Relevance: Google evaluates the relevance of the keywords in the advertiser’s campaign to the user’s search query. Ads with more relevant keywords have a better chance of appearing.
    • Bid Amount: Google considers the bid amount set by the advertiser. A higher bid doesn’t guarantee top placement but can improve the chances of getting displayed.
    • Ad Quality: Google assesses the quality of the ad, which includes factors like ad copy relevance, click-through rate (CTR), and the quality of the landing page. Ads with better quality scores may outrank higher-bidding ads.
  5. Ad Rank: Google calculates an Ad Rank for each ad in the auction, which determines the ad’s position on the search results page. Ad Rank is calculated using the formula: Ad Rank = Bid Amount × Quality Score.
    • Bid Amount: This is the maximum bid the advertiser is willing to pay for a click.
    • Quality Score: A metric that assesses the quality and relevance of an ad and its landing page. It’s based on CTR, ad relevance, and landing page experience.
