Guest blogging is a pretty straightforward way to grow traffic to any website. As long as you're guest blogging on a site that has considerable reach, it should generate some healthy traffic numbers for you. Even better? Ensure that the guest blog is topical or related to the industry that you're in. You might find a hard time convincing popular blogs and bloggers to guest blog on their site, but it's well worth it when just one of them agrees.
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.
No, unfortunately we can not guarantee that the absolute safety of Google Adsense Traffic. This is because we have seen instances in which websites were penalized for receiving large bulks of traffic (and clicks) to their Google Adsense ads. Therefore, if you use it, we strongly recommend you to use it in moderation and in conjunction with other traffic sources. More information >>
