SEO is the process of optimizing a website to rank higher in search engine results, making it more visible to people searching for relevant keywords. This involves on-page and off-page optimization techniques to improve organic (non-paid) search traffic.
SEM involves using paid advertising on search engines (e.g., Google Ads) to display ads in search results. Advertisers pay each time a user clicks on their ad. PPC campaigns are highly targeted and allow for quick results.
Social media marketing entails creating and sharing content on social media platforms like Facebook, Twitter, Instagram, and LinkedIn. It helps build brand awareness, engage with followers, and drive traffic to your website.
