Social media marketing and search engine optimization are both ways to promote articles in content marketing. They are both inbound channels. But they are very different from each other. In fact, social and search are opposites in many ways.
SEO is about being discovered and getting traffic through search engine rankings. It fills the top of the funnel and creates awareness. Whereas Social media marketing is about connecting, building relationships and getting traffic from social media networks like Facebook, Twitter, Instagram, Pinterest etc. It strengthens the middle of the funnel and creates engagement.

Yes, social media marketing and SEO (search engine optimization, Digital Marketing) are different but complementary strategies in digital marketing.
Social media marketing involves promoting and engaging with your target audience on social media platforms like Facebook, Twitter, Instagram, and LinkedIn. The goal of social media marketing is to build brand awareness, generate leads, and drive website traffic through social media channels.
SEO, on the other hand, involves optimizing your website and content to rank higher in search engine results pages (SERPs) for relevant keywords. The goal of SEO is to increase organic traffic to your website through search engines like Google, Bing, and Yahoo.
While both social media marketing and SEO aim to drive traffic and improve online visibility, they differ in their approach and tactics. Social media marketing involves creating and sharing engaging content on social media platforms, interacting with followers, and using social media advertising to reach a wider audience. SEO involves optimizing website structure and content, building backlinks, and using relevant keywords in on-page and off-page optimization efforts.
In summary, while social media marketing and SEO are different strategies, they can work together to improve online visibility, drive traffic, and increase conversions for your business.
