What is the best way to use SEM for lead generation

The best way to use SEM for lead generation is to create targeted campaigns that focus on specific keywords related to your product or service. You should also create compelling ad copy that is tailored to the audience you are targeting and use remarketing campaigns to reach out to people who have already visited your website. Additionally, you should use A/B testing to optimize your campaigns and track your results to measure the effectiveness of your efforts.
