Here’s a brief explanation of the question – what is Google AdWords?

Google AdWords is an advertising platform by Google. It allows advertisers to show ads on Google’s ad inventories which include – Search Engine Result Pages (SERPs), Search Partners, and Google Display Network (GDN).

AdWords is an auction-based advertising platform where advertisers need to place bids on keywords to show their ads on Google. It is also important to note that, unlike any other advertising system, AdWords uses a second price auction system to decide various ad positions and actual costs for ads for different advertisers. It makes AdWords a unique advertising system where ads’ pricing is decided not only by the amount someone bids but by a combination of bids and ads’ quality score.

It’s easy to spot an AdWords ad on Google SERPs, partner search engines, or on a web page, app etc. from GDN. Some of the examples ads from AdWords are given below. Usually, these ads have clear indications like – Ads by Google, Sponsored etc.
