What are paid keywords? [SEO]?

 In the context of search engine optimization (SEO), paid keywords refer to the use of paid search advertising to target specific keywords or phrases that users are searching for. When a business buys a paid keyword, their ad will appear in the sponsored results section of the search engine results page (SERP) when someone searches for that particular keyword. The business pays the search engine a fee each time someone clicks on their ad, which is known as "pay-per-click" (PPC) advertising. Paid keywords can be a useful way for businesses to drive traffic to their website and increase their visibility in search results, especially for highly competitive keywords or phrases.
