PPC stands for pay-per-click, a model of internet marketing in which advertisers pay a fee each time one of their ads is clicked. Essentially, it’s a way of buying visits to your site, rather than attempting to “earn” those visits organically.

Responsive search ads are an innovative form of advertising which allows marketers to come up with multiple descriptions and headlines for their ads.

In other words, a responsive search ad is a form of Google Ad that allows creators to create as many as fifteen titles and four descriptions at once. 

It is an effort from Google to make search ads more flexible and productive.

A zero-click SERP is one where the answer is displayed directly at the top of a Google search result.

The search intent of the user is satisfied without having to click any actual search result links.

Search intent is the why behind a search query. In other words, why did the person make this search? Do they want to learn something? Are they looking to make a purchase? Or, are they looking for a particular website?

 UX is a qualitative foundation for digital marketing, or you can say any marketing. User experience can be defined as the understanding of user needs to help and create products and services that provide a meaningful experience to the customers.

A social media platform's live feature provides a better source of interaction between the influencer and their audience.
For Example:
