In my last blog on whether you should use Pinterest for your inbound marketing plan I mentioned that the platform was made for collectors and that it drives more referral traffic then YouTube, Google Plus and LinkedIn combined. Even with over 21 million users Pinterest may not be the best platform for you. Just because a social media platform has a lot of users and is very successful does not mean that you should use it for your inbound marketing strategy. A personal example would be StumbleUpon. According to shareaholic SutmbleUpon has the second highest traffic referral rates and fairly decent user base of 16 million worldwide users. Indeed, 14% of inbound traffic to my website from social media sites has come from StumbleUpon. Yet I have not received one lead from that traffic. I get less traffic from Twitter and Facebook but more leads. For some reason StumbleUpon and my site just don’t click. That’s fine, I do a lot better on LindedIn with my largest share of traffic and leads coming from organic search. Just because a site is popular does not mean it’s a good fit.
