Very good tips on traffic generation. However, for those with time constraint, back-links is a quick method along with another easy method, blog commenting. I would second most of the people who commented in support of guest posting. Yahoo answers may get mixed responses depending on the topic. If you have time, you can also post on related forums and try video marketing.
You have also mentioned Quuu for article sharing and driving traffic. I have been using Quuu for quite sometime now and I don’t think they’re worth it. While the content does get shared a lot, there are hardly any clicks to the site. Even the clicks that are there, average time is like 0.02 seconds compared to more than 2 minutes for other sources of traffic on my website. I have heard a few guys having a similar experience with Quuu and so, I thought should let you know.
Social media is one of the most popular free marketing tools around, and plays a role in driving traffic to your website. Use Facebook, Instagram, and LinkedIn to promote blog posts and other useful pages on your website. This way you can turn your social media audience into website visitors, and draw traffic from their networks if you post shareable content.
