Social is no longer just about conversation and content; it’s now an established channel for customer acquisition, remarketing and engaging existing fans/customers to support retention programs. It may be relatively immature compared to search and email marketing but it’s a channel in which most ecommerce teams are ramping up investment (people and tools).
You can also make sure that you’re not bleeding revenue due to friction somewhere along that path. How does that work? When you focus on organic search traffic, you’re compelled to take the battle to multiple marketing fronts. While SEO outperforms all other channels regarding ROI, it doesn’t always work in isolation. Email marketing, content marketing, social media, and other channels can all serve your SEO strategy. I’ll tell you something about marketers who are truly worth their stuff.
The advantage of paid search is that you can have your website listed on the first pages in a prominent spot on Google and other search engines. However, showing up is only part of the process. You need to create an ad that not only leads to clicks, but to sales or whatever result you're looking for. If you don't know what you're doing, it's possible to write an ad that people are drawn to and click on, however, you don't make sales. Since you pay per click, and clicks can add up quickly, you can lose money.
