Is social media marketing better for B2C or B2B businesses?

BTC definitely, however, you can take advantage of Social Marketing in B2B as well. 

Need more inspiration to guide your marketing campaign and to see real-life examples of B2B versus B2C ads? AdEspresso has compiled 50 of the most successful B2B ads posted on Facebook. Check out what they all have in common: clean graphics, Twitter worthy intros, and no humor to be found anywhere.

In 2015, B2B company The Digital Marketer posted more than 4,500 ads on Facebook. You may want to check out their map of what copy worked, what didn’t, and how to design the best images that get attention.

Now for B2C, Business to Community has compiled a list of the best social media campaigns of 2015. From Star Wars to Starbucks, you can see which companies stood out last year and the ads that brought in the money.

Even though the map to get to the final destination is clearly different, the desired result of making a profit is the same… and so are the fundamental principles. As Dhamdhere wisely comments about B2B and B2C marketing, there are a few things that remain same: the “need to communicate powerfully and effectively with the customers… because whether it’s B2C or B2B, ultimately it’s B2P, i.e. business to people.”

It's equally useful and important for both. After all, managers and decision makers use social media, too. 

B2B social media marketing differs, however, from one geographical area to another in terms of platformes used. 

(Subreddits for specific professions, LinkedIn, and Twitter are some channels I think B2B social media marketing thrives in. Again, it depends on how business managers in the target region use social media.)
