In the context of internet marketing and SEO, a bid refers to the amount of money an advertiser is willing to pay for each click on their ad or for each thousand impressions of their ad. Bids are typically set in online advertising platforms, such as Google Ads, and play a crucial role in determining the ad’s position and visibility in search engine results or on websites. Higher bids often result in better ad placement and increased chances of attracting relevant traffic to a website.
