PPC, or pay-per-click, is an online marketing model in which advertisers display ads on websites and only pay when a user clicks on the ad. The three R's of PPC are:
1. Research: Advertisers must carefully research potential keywords and create ad groups around themes to ensure their ads are relevant to users' search queries.
2. Relevance: Ads must be relevant to the keywords they are targeting and the user's search query in order to be effective.
3. ROI: Advertisers must track their campaigns closely to ensure they are getting a positive return on their investment.
PPC can be an effective way to drive traffic to your website and generate leads, but it is important to keep the three R's in mind to ensure success.
